SCCOOS Coastal Ocean Currents Monitoring Program 1 2007 Annual Report

Executive Summary

The following document represents the 2007 Annual Report for the Southern California Coastal OceanObserving System (SCCOOS) implementation of the Coastal Ocean Currents Monitoring Program(COCMP) in Southern California. Presently in the third of a three-year grant from the California StateCoastal Conservancy (SCC), SCCOOS is developing and implementing ocean current monitoring infrastruc-ture for the region in a manner that is best suited for a broad range of regional and statewide needs. Programobjectives are met and enhanced through partnering activities organized through SCCOOS, a consortiumengaged in implementing a multi-disciplinary ocean observing system for the region, and one of elevenRegional Associations (RAs) operating a Regional Coastal Ocean Observing System (RCOOS) as part of theIntegrated Ocean Observing System (IOOS). Executed through a parent grant to the business office of theMarine Physical Laboratory at Scripps Institution of Oceanography, organizations supported throughCOCMP include the University of California at Los Angeles, Santa Barbara, and San Diego, the Universityof Southern California, Raytheon Corporation and the Jet Propulsion Laboratory. The program also supportssignificant subcontracts to California-based equipment vendors and service providers. Alliances with dataprovider user groups, private interests, and state, local, and federal agencies are a central part of our systemdevelopment efforts to entrain the widest range of interested parties to participate in California’s oceanobserving investments.

COCMP system components include Surface Current Mapping (SCM) to map ocean surface currentswithin the Southern California Bight; high resolution (GPS-tracked) drifters; propeller and buoyancy driv-en autonomous platforms; surf zone current measurements and modeling; a Regional Ocean ModelingSystem (ROMS) with data assimilation for nowcasting and forecasting of the physical properties of the ocean;and IT infrastructure compatible with federal planning efforts for IOOS. Data from HB06, the focused, inte-grative effort of many of the COCMP components executed in the Huntington Beach area in response torequests from early stakeholder input to the COCMP design process, continue to be analyzed and modeled.This end-to-end effort served to connect nearshore observations with end-user water quality needs, anddemonstrated the capabilities of observing system technologies across a wide range of conditions.

Data and information products are now being made available at the SCCOOS web site (www.sccoos.org)in near real-time, and integrated with monitoring data obtained by regional data provider user groups whenthose data are made available. Examples of web-based products are provided in Appendix A to this report.

The SCCOOS implementation of COCMP includes an internal program management structure thatallows efficient design, installation, and operation of the California Proposition 40/50 funded infrastructure.COCMP is one of the building blocks of capacity for both regional and state observing systems. To this end,SCCOOS is committed to coordinating with the Central and Northern California Coastal Ocean ObservingSystem (CeNCOOS) to ensure a unified statewide system, and to achieve a minimum level of interoperabil-ity, as articulated in the Memorandum of Understanding (MOU) signed in December of 2003.

Introduction

This report represents the efforts of the Southern California Coastal Ocean Observing System forCOCMP in calendar year 2007. With the official start for the program in mid-March 2005, SCCOOS isnow in the 31st month of a nominal three-year program. While the infrastructure implementation phase ofthe Proposition 40/50 sponsored system is not yet complete, we are routinely reminded of the value of thesystem by the numerous data requests we receive, and the enthusiastic reception COCMP has with region-al stakeholders.

Six new HF radar sites were installed and networked with the other California stations in 2007 by USC,UCSB, Cal Poly, and Scripps, bringing the number of sites to a total of 45 for the entire state. In addition, per-missions for several new stations were approved at the close of the year, allowing COCMP-sponsored tech-nical staff to proceed with the installation of equipment in early 2008.

Underwater glider work has continued, with operations now expanded to sample the subsurface oceanoffshore Monterey. This on-shore/offshore transect complements transects offshore Central and SouthernCalifornia. These are providing valuable data that is being used to understand the larger scale ocean climateand variability known to play a role in controlling coastal ecosystems.

Participants of the Huntington Beach 2006 nearshore and surf-zone demonstration (HB06) continue tointerpret, analyze, and integrate data sets collected during the intensive collaborative project.Demonstration partners met in June 2007 to review the effort and to coordinate next steps. Deliverablesinclude a bundled data product for users, a list of ranked priority applications, and a list of optimized set ofinstruments. An outcome of HB06 has been an improved model of surf zone currents and circulation for theHuntington Beach/Santa Ana River region. This model continues to operate, and provides nowcasts andforecasts to local managers on a routine basis.

With the COCMP investment in modeling, the ROMS team of UCLA, JPL, and Scripps continue toimprove our ability to predict ocean behavior. The 1km resolution ocean model is now in routine operation,with nowcasts and forecasts created every six hours. The ocean modeling team has also developed new gap-filling algorithms based upon statistics of the data that are proving valuable for generating operational sur-face current products. The technique has also been used for an assessment of Mexican discharges enteringthe U.S. (for EPA), and more recently to assess surface currents in the San Francisco bay region during theCosco Busan spill. The Los Angeles and Long Beach Ports region has expressed interest in this application,and is working with SCCOOS to access surface current and wave data for the area.

The data management team has worked with model operators to provide user-friendly tools to accessand visualize the ocean model output for Southern California. With the modeling infrastructure nearingmaturity, an important task will be to test and validate the utility of the model for specific user missions. Tothis end, the data management team is tabulating model results from the system at specific ocean dischargelocations in order to conduct a performance assessment.


Working with stakeholders and the SCCOOS Senior Advisory Committee (which includes several stateagency representatives), SCCOOS has identified the following topical areas as regional priorities for theobserving system:

• Water quality, including harmful algal blooms

• Climate variability and marine ecosystems

• Search and rescue, marine safety, and oil spill response

• Public uses of SCCOOS data

These priorities remain consistent with COCMP program objectives and state goals. SCCOOS looksforward to continued collaboration with the State Coastal Conservancy in implementing a state-of-the artocean observing system that meets the needs of the state, and serves as a model for the development of a sci-ence-based decision support system for the country.

Tasks and Deliverables

The Coastal Ocean Currents Monitoring Program for Southern California will continue with the activi-ties proposed in our original grant agreement. Estimated time periods are provided in bold and parentheses torepresent the minimum requisite time period to complete each task, and do not represent man months of effortexpended. These periods do not necessarily commence on the date of the approval of the Annual WorkProgram but are program dependent and are often inter-related to the progress of other related tasks. Therefore,these periods are initiated, managed and may be modified at the discretion of the program scientists.

2007 Work Program for Task A• Continue the installation of new sites to achieve full build out of the SCCOOS COCMP HF radar

network. Our projected install rate is seven sites/year. Locations will be determined in conjunctionwith Task A.1, and prioritized based on site accessibility and permitting response. Proposed andactive HF radar sites can be viewed from http://www.sccoos.org/SoCal. Our targeted sites includecompletion of the LA Basin region and installations in both northern San Diego and the region ofcoastline between Point Conception and San Luis Obispo.

• Install communication hardware where necessary as sites become available in order to operate andconfigure remote sites.

• Continued IT development to deliver hourly radial and combined ocean surface current measure-ments for near real-time monitoring. Provide data in multiple formats that provide utility to COCMPuser-base.

Deliverables for December 2007:

• Status report on HF radar systems and product development. Updated map of SCM antenna locationsalong the coast, continued documentation submitted for proposed site requests permits.

• Site Installations for an estimated 7 sites. Projected locations include: Diablo Canyon, Santa CruzIsland (2 sites), Point Sal, Nicholas Canyon, Newport Beach, Dana Point, Point Loma

• Prototype, Integrated real-time data products of surface currents. (ongoing development activity dis-tributed over 12 months)

GoalsMapping of ocean surface currents has been identified as a cross-cutting activity to a number of region-

al observation needs and science issues. The goal of the HF radar component is to establish an array of sur-face current mapping radars in Southern California. This program is conducted in concert with SouthernCalifornia Coastal Ocean Observing System (SCCOOS) HF radar operators located at California PolytechnicState University (Cal Poly), University of California, Santa Barbara (UCSB), the University of SouthernCalifornia (USC), and Scripps Institution of Oceanography (SIO). These radars are part of a larger scale sur-face current mapping (SCM) network that, when combined with Central and Northern Coastal Ocean

A. ESTABLISH SCM ARRAY FOR MAPPING OCEAN CURRENTSCollaborating Program Scientists: Mark Moline (Cal Poly), Burton Jones (USC), Libe Washburn (UCSB), Eric Terrill (SIO)


Observing System(CeNCOOS), allows COCMPto cover most of the Californiacoast. The HF radar arraymeasures surface ocean cur-rents for use in a broad rangeof practical and scientificapplications as discussed atthe SCCOOS website(www.sccoos.org) such assearch and rescue operations,storm water management, oilspill response and fisheriesmanagement.

Progress Toward GoalsEntering the third year of

the program, activities haveincluded final assessments of HF radar locations, completion of new installations, processing of permits tooccupy private and public property, finalizing supporting equipment to include outdoor enclosures and air-conditioning units and telemetry, and operating and maintaining existing HF radar sites. The 2007 WorkProgram included seven site installation estimates for the year: Diablo Canyon, Santa Cruz Island (2 sites),Point Sal, Nicholas Canyon, Newport Beach, Dana Point, and Point Loma. SCCOOS HF radar participantsinstalled a total of six SCM sites. Installed locations deviated slightly from the 2007 estimate due to re-pri-oritization of permitting. Installed sites for 2007 include: Diablo Canyon, Santa Cruz Island, Point San Luis,Fallback 22 (formerly Point Sal), Nicholas Canyon, Dan Blocker, and Dana Point. SCCOOS maintains sitestatus through an interactive web page.

• Evaluate physical locations for SCM antennas deployment taking into account local noise, distance tothe ocean, potential structural interference, and site permission process.

• Assess installation logistics particular to each site location. Determine means of equipment transportincluding car, boat, and helicopter travel.

• Note foreseeable impediment to successful installation and operation of SCM locations. While acces-sible power and communications significantly ease site construction, existing buildings, towers, andground characteristics can significantly affect the performance of SCM antennas.

Deliverables for December 2007: Status reports as required on site assessment detailing location and existinginfrastructure beneficial or detrimental to setup, installation milestones anticipated particularly for remotesites with no existing power and/or communications.

Progress for Task A.1SIO SCCOOS programmers

have developed an interactivesite management tool for SurfaceCurrent Mapping antenna sys-tems: www.sccoos.org/SoCal.The site is used for planning pur-poses, and includes CaliforniaCoastline Records Project,Google maps, and Topozonelinks to radar sites based on GPSlocation. Users are able to viewavailable geographic informationfor the site location, and uploadimages taken at the site locationfor discussion and review. Thesite hosts publicly displayed data,such as site name, affiliation,owner information, location,

images, and public notes or files, as well as login required information such as maintenance notes, and pri-vately maintained images and contributed files. This management tool has been replicated for CeNCOOS(www.sccoos.org/CeNCOOS), providing statewide consistency and compatibility. SCCOOS programmersare currently working toward an improved front end for this site management tool, which will provideincreased continuity between SCCOOS and CeNCOOS.

CalPoly, UCSB, USC, and SIO continued efforts on HF radar site assessments and permissions through-out the year of 2007. Assessments were made to evaluate physical locations for HFR antenna deployments,taking into account radio interference, distance to the ocean, potential structural interference, and the effortrequired to gain site permissions. Installation logistics particular to each site location were investigated, andphysical accessibility to the sites determined. Existing buildings, towers, and ground characteristics weretaken into account, as they can significantly affect the performance of HFR antennas. A status report onSCM Site Assessment for each site is as follows:

Southern California*Point Loma: A site at the Point Loma Wastewater Treatment Plant would provide coverage north of the point,and combine with radials from the existing site installed on US Navy property at Battery Humphries.SCCOOS personnel recently received an approved “Right of Entry” from the City of San Diego grantingdeployment approval. The site will be installed early 2008.

La Jolla: The lifeguard station at the La Jolla children’s pool is an excellent location for an SCM site. This sitewould provide coverage within La Jolla cove and combine with the long-range system at SIO, as well as theSan Elijo site to the north. This location has proved difficult to obtain permissions for due to its location indowntown La Jolla, and we are considering relocating to a site at Camp Pendleton.

† San Elijo: The San Elijo State Park site provides coverage to both the north and south, as the view is unob-structed. This site is advantageous in that the antenna is mounted on an existing light post, and does notinterfere with any views since the park is located along a stretch of highway in San Elijo. No status change.

*Camp Pendleton (formerly Oceanside/Carlsbad): SIO initiated discussions with Camp Pendleton personnel for adeployment on military property just south of the LCAC (Landing Craft Air Cushion) facility. Upon furtherreview, it was determined that this location is in an operationally sensitive area. SCCOOS personnel workedwith Camp Pendleton operations and environmental personnel to determine an agreeable site location. Thelifeguard facility at Camp Del Mar at the southern point of Camp Pendleton, and a former LORAN site atSan Mateo at the northern point of Camp Pendleton both proved to be suitable locations. Site approvals forboth locations are in the final stages. The San Mateo site will require a solar power solution, while the CampDel Mar site will utilize existing lifeguard infrastructure.

† Santa Catalina East: Located at the Wrigley Institute for Environmental Studies, the radar currently combineswith Point Fermin, Dan Blocker and Dockweiler providing coverage of San Pedro Bay, as well as part of SantaMonica Bay. This site provides direct access to the USC network for communications. No status change.


† Dana Point: The Headlands Harbor PointPark at Dana Point would have been anideal location for an SCM installation,given the wide field of view and geo-graphic protrusion from the coast. TheCity of Dana Point, however, denied therequest for an installation under theHeadlands Park conservation easementagreement of March 2006. SIO receivedapproval from the Ocean Institute todeploy a system on the roof of the westernmost building. This site was installed inFebruary, 2007.

*Newport Beach: The end of the Newport Beach Pier was selected due to its unobstructed views both north andsouth. This site will provide coverage of the southern portion of San Pedro Bay, including Newport Harbor,Santa Ana River and Talbert Marsh. This system will combine with radars located on Santa Catalina Island,Point Fermin and Dana Point. Testing has taken place and the site is deemed viable. SCCOOS personnel havesubmitted detailed engineering drawings, received signature approval from a licensed professional engineerand are in the final stages of the approval process.

† Dockweiler (formerly Huntington Beach): The LA County Lifeguards installed permanent lifeguard structures atDockweiler Beach that have both power and data capabilities. This site proved to be an excellent locationfor the Central Santa Monica Bay site. Together with the Dan Blocker and Catalina radars, coverage includesthe mouths of Ballona Creek and Malibu Creek. The LA County Lifeguards have been extremely coopera-tive in allowing installations at their facilities. SCCOOS has benefited from a long term-relationship withmembers from WatchTheWater.org. No status change.† Point Fermin: This site is located on the southern tip of the Palos Verdes Peninsula overlooking the entranceto the L.A. Harbor. Situated on USCG property, the site is secure and provides coverage north towardMalibu, south toward Newport Beach and west to Catalina Island. This is an area with a high volume of ves-sel traffic. No status change

*Point Vicente: Following several site surveys, USC has determined the best location for an SCM site would beat an L.A. County Lifeguard station in Redondo Beach. This location provides good coverage for southernSanta Monica Bay, where it interacts with the Dockweiler and Dan Blocker radars, and seaward to the SSW,where it overlaps with the Catalina radar. This is a site in development; we are awaiting permission from theCounty Lifeguards to allow a more complete evaluation of the site.

† Dan Blocker (formerly Point Dume): Dan Blocker (Corral Beach) is located on the north side of the Santa MonicaBay in Malibu. The antenna is currently attached to the lifeguard stand, which offers a close proximity tothe water. This site was chosen because power and communications already exists at the site due toWatchTheWater.org installations, and because of the coverage it provides. The Dan Blocker radar combineswith Dockweiler and Catalina Island. The site was installed in September 2006, and remained operationalthrough February 2007, when lifeguards shut down power due to radiation hazard concerns. Since this time,

SCCOOS personnel have worked with lifeguards to answer all questions and concerns regarding the safeoperation of a surface current mapping site. These conversations have persisted throughout the year; the siteshould become active in early 2008.

Central Coast California† Santa Cruz Island (formerly Anacapa Island): Radials from a site on the south side of Santa Cruz Island would com-bine with radials from sites Pt. Mugu, Ormand generating station, Zuma Beach, and/or Leo Carillo State Parkto extend coverage to ocean areas south of the northern Channel Islands. Permission was obtained for a U.S.Navy controlled location, and deployed in May 2007. After operating for about 3 months, Navy personneloperating the site realized that they had mistakenly given permission to use the site, and UCSB staff wereinstructed to shut down and disassemble the equipment. UCSB is now in the process of obtaining site per-mission through the Naval Base Ventura County, who legally manages this site, the site at Pt. Mugu, and asite located on San Nicolas Island. A land use agreement for the three SCM sites is in the latter stages of nego-tiation between the US Navy and UCSB Business Services office.

*Point Mugu (formerly Oxnard): This site looks very promising since it would provide extensive coverage of areassouth of the Northern Channel Islands and east of the Santa Barbara Channel. It is also a secure locationbecause it is on the naval base at Pt. Mugu. UCSB personnel are working to obtain permission to use thePoint Mugu site by submitting information as requested by US Navy personnel. UC Regents approved pay-ment of $7500 for the Electromagnetic Interference, Electromagnetic Compatibility, Hazards ofElectromagnetic Radiation to Personnel, and Hazards of Electromagnetic Radiation to Fuel(EMI/EMC/HERP/HERF) studies. This study was completed in 2007. Permissions for this site have beengrouped into one request for Santa Cruz Island, Point Mugu, and San Nicolas Island, and are under reviewwith UCSB Business Services office.

† Nicholas Canyon (formerly Ventura): As with Pt. Mugu, this site would provide coverage of ocean areas south of thenorthern Channel Islands and outside the eastern entrance of the Santa Barbara Channel. Permission wasobtained from Los Angeles County Lifeguards to install on existing infrastructure owned by the lifeguards.A 25 MHz collocated antenna was installed at the site and operated for about a month. Lifeguards workingat the site were concerned with the radiation from the CODAR, despite evidence presented regarding itssafety. They threatened their management with union actions, forcing a compromise. We agreed to shut thesite down and move to a slightly different location, which requires approval from the city of Malibu. TheCity of Malibu initially gave verbal approval of the project, and UCSB obtained a final written permit toinstall electrical infrastructure.

*Point Conception: A site at Point Conception, especially in combination with a site at Point Arguello, wouldprovide extensive coverage of the upwelling center there, and include many of the oil production platformsin the region. The permissions process is in the final stages with the USCG. Following submittal of a plan,the USCG requested that SCCOOS staff determine a source of electrical power to USCG station, ensuringthat electrical lines remained separate. Following several incorrect leads for Southern California Edison andPG&E, staff has determined power runs through Vandenberg Air Force base, and is now able to pursuerequested action.

Point Arguello: Our examination of likely coverage indicates that this would be a good location for two SCMsites, one long range and one medium or short range. Radials from a long-range system at Point Arguello


would combine with those from Santa Rosa Island to produce total current vectors over a large area oceanarea south of the Northern Channel Islands. SCCOOS staff submitted a site request for Point Arguello; how-ever, the USCG has determined this site is not optimal for a SCM system. This location cannot support trans-mitting antennas. Even the USCG landowners were unable to install a system that required transmission,and had to go to Vandenberg Air Force Base (VAFB). SCCOOS personnel are currently working with VAFBfor an agreeable solution.

† Fallback 22 (Point Sal): This site would provide overlapping coverage with radars at Pt. Arguello and Pt. SanLuis. On November 13, 2007 Cal Poly received the fully executed license from the United States Air Forceto access and reactivate the SCM site on Vandenberg Air Force Base (VAFB) just south of Point Sal, former-ly installed by UCSB. The Fallback 22 site license given to Cal Poly also granted access to SCCOOS person-nel from UCSB. The site was online by end of November 2007.† Point San Luis: The fully executed license to access, install, and operate a SCM site at Point San Luis (LUIS) wasreceived by Cal Poly from the USCG on November 27, 2007. Additional installation and access permissionfrom the joint landowner, the Port San Luis Harbor District, was granted on October 5, 2006. The site wasinstalled in December, 2007.† Diablo Canyon (formerly Point Buchon): Permission was secured from PG&E to install both a long-range and a stan-dard-range SeaSonde at their Diablo Canyon Power Plant. Brian Zelenke presented the COCMP programat Cal Poly to PG&E management on November 29, 2006, culminating in official support from the DiabloCanyon Power Plant for the COCMP. PG&E, however, was unable to provide power to the site; therefore,Cal Poly staff have sought a solar power solution. Diablo Canyon supports a long-range system (CeNCOOS)and high resolution system (SCCOOS), installed in May 2007.† Point Estero: A number of sites on the Abalone Farm in Cayucos near Point Estero were accessed for their suit-ability for HFR measurements. The site is currently installed at the optimal location surveyed.Measurements of the frequency space present at the Abalone Farm between 12-14 MHz showed radio sta-tion interference from 13.41-13.57 MHz in the WFM band, impeding operation using the intended fre-quency of 13.5 MHz. Federal Communications Commission (FCC) permission was sought to operate at alower band and a Special Temporary Authority (STA) was granted for operation at 12.165 MHz. No statuschange.

Task A.2 Site Permissions


• Identify and contact local land owners regarding necessary site permits for installation and site visits.

• Perform and document any required permission surveys where needed. To be completed where nec-essary

Deliverables for December 2007: Status reports as required on site permissions outlining granting agenciesand documentation submitted for site approval. Included in this report will be details on antenna character-istics and accessory equipment.

Progress for Task A.2The permissions process proves variable for each location, depending particularly on site owner and

land situation. SIO SCCOOS personnel have compiled surface current mapping focused literature, enablingstaff to present a common informational package to site owners. The folders and pamphlets have provenextremely valuable when requesting permissions, and provide an overview of program goals, instrumentdetails, and site requirements.

SCCOOS personnel have pursued permissions with the USCG since the inception of COCMP, and havereceived finalized permissions for Point Fermin and Point San Luis. After receiving the license from theUSCG to install a SCM site at Point San Luis on November 27, 2007, Cal Poly technicians arranged for ameeting on-site with the USCG Sector Los Angeles-Long Beach Aids to Navigation Team (ANT) onDecember 11, 2007. The USCG ANT personnel who operate and maintain the USCG equipment at Pt. SanLuis provided guidance to technicians regarding power installation. The following day on December 12,2007 Smith Electric completed the electrical wiring, thereby providing power to the SCM site. OnDecember 18, 2007 Cal Poly staff fully deployed the SCM site at Point San Luis and SIO staff integrated datato the national network on December 20, 2007. Antenna pattern measurement calibration of the site isplanned for 2008.

A joint effort between UCSB and Cal Poly SLO researchers resulted in a fully executable agreement foruse of a previous SCM site near Pt. Sal. UCSB researchers were able to obtain a real estate lease documentfrom the US Air Force detailing the requirements for establishing a SCM site on Air Force property. Whenit was determined that the business services office at UCSB was unwilling to sign the agreement, and the AFwas unwilling to modify the agreement, researchers at SLO presented the agreement to their office whowere able to accept the agreement as is. The site was installed by UCSB and SLO researchers, and is now fullyoperational.

As SCCOOS is unable to install SCM sites on USCG property at Point Arguello, UCSB researchers vis-ited Vandenberg Air Force Base to reassess the area outside the USCG property. With the extended capa-bilities of a recently developed transmit antenna, new potential sites were identified and assessed. Some exist-ing infrastructure is present, such as power, although non-grid power might be required. For networking,satellite communications will almost certainly be required, due to lack of other options in the area.Researchers at Cal Poly SLO are pursing an agreement with the Air Force to occupy one of these sites.

UCSB researchers visited a site near Gaviota to assess the location for suitability as an SCM site. UCSBpersonnel have pursued an agreement with the landowner, Union Pacific Rail Road, with the help of a con-


sultant who has a thorough knowledge of the area and its governmental requirements. Although UnionPacific has been unresponsive, UCSB has obtained a letter of support from a local congress person.

Task A.3 Frequency Allocation


• Maintain FCC current FCC licenses. Make adjustments as needed for new radar sites.

Deliverable for December 2007: SCCOOS acquisition of FCC experimental licenses for all proposed HFradar sites. Status report.

Progress for Task A.3SIO SCCOOS personnel submitted an FCC experimental site request for 18 additional locations spanning

several frequencies on April 27, 2005, which was the largest request the department had ever received. TheFCC partially granted the request on February 10, 2006 for 17 of the 18 locations. The FCC application willneed an update of locations in order to accommodate the repositioning of two sites: Dan Blocker replacingPoint Dume and Dockweiler replacing Huntington Beach due to ease of permissions and improved coverage.

SCCOOS has submitted an FCC license renewal on 18 May 2007. NOAA is pursuing approval andtransition of HF radar for mapping surface currents into the permanent frequency band. NOAA has request-ed several center frequencies with bands in the 25MHz, 13MHz, and 5MHz frequency range. We antici-pate that this process will take 4-5 years for approval. SCCOOS will continue to operate under the existingexperimental licenses. If the May 2007 renewal is denied, SCCOOS surface current mapping systems will bealtered to operate under existing NOAA experimental licenses.

This past year, SCCOOS staff began experiencing crippling radio interference on October 29, 2007 atDiablo Canyon for approximately eight hours per day, typically between the hours of 7:00 A.M. and 7:00P.M. PST. During the periods when the interfering radio signal was transmitting, the SCM sites were unableto make any measurements. University of Southern California also reported radio interference at their SCMsite on Santa Catalina Island (SCCI). Cal Poly technicians Brian Zelenke and Dan Elmore traveled to DCSRon November 11, 2007 and made recordings and measurements of the interfering radio source and deter-mined that it spans the frequencies 13.5-13.525 MHz. This range of frequencies is of particular concern asit falls directly within the only frequency band for which SCCOOS is permitted by the FederalCommunications Commission (FCC) to operate its standard-range SCM sites.

Figure 4. Diablo CanyonStandard Range (DCSR) —Antenna loop pattern meas-ured at DCSR withoutsmoothing (left) and with 20°smoothing (right) as meas-ured by the antenna beampattern calibration.Calibration occurred prior tofrequency interference.


With the assistance of Bill Rector of CODAR Ocean Sensors (COS), a likely source location for theinterfering signal was suggested: TV Tower Road along the ridge of the Cuesta Grade in San Luis Obispocounty. On November 27, 2007 Cal Poly staff drove to the two commercial antenna sites along TV TowerRoad. Measurements of the radio environment with both an Icom receiver and a Hewlett Packard spectrumanalyzer suggested that the interfering signal wasn’t originating from these antennas. The signal presentedas a constant car-horn like tone that appeared to be an artifact of malfunctioning equipment, as it did notappear to contain any information or speech. Further attempts to direction-find the interference yieldedsuch a large search radius that it was not possible to pinpoint the origin of the interference with the equip-ment available.

The interfering signal ceased transmission for approximately a week around the Thanksgiving holidayand again stopped transmitting about a week before Christmas. That the interfering signal is present mainlyduring working hours and that it has stopped being transmitted during traditional vacation times suggeststhat the source emanates from a malfunctioning piece of equipment used by a business. As of this writing theinterfering signal has yet to resume broadcast. If this radio interference returns, further efforts in conjunc-tion with COS and SCCOOS partners will be made to determine the source and nature of the interferencebefore requesting the assistance of the FCC.

Task A.4 Site Preparation and Equipment Order


• Determine additional hardware required for site operation. Consult with hardware vendors as need-ed to maintain delivery schedules.

Deliverable for December 2007: Progress report of delivered HF radar equipment.

Progress for Task A.4Significant efforts have gone into assessment of

enclosure specifications, reliable data communications,and power requirements. These standards have been inte-grated into the technical document: Deployment &Setup of a High-Frequency Radar for Ocean SurfaceCurrent Mapping: Best Practices, which details lessonslearned and recommended deployment and operation ofCODAROS HF radar systems.

SCCOOS is currently entering the final year of HFradar systems delivery from the equipment vendor.CODAROS has delivered fifteen to date, and fourteen systems have been installed. In 2008, seven more sys-tems will be delivered. A 25MHz system at SIO is being tested, and will be deployed at the Point LomaWastewater Treatment Plant in early 2008. UCSB and SIO group modified the COCMP equipment orderto upgrade six older UCSB CODAR SeaSonde units. The upgraded systems will have GPS timing, USB con-nectivity, and be able to use updated CODAR Ocean Sensors system software. The upgrades are necessaryto allow the systems to share the frequency spectrum with other SCCOOS HF radars, and to prevent themfrom becoming obsolete. The final (6th) SeaSonde system upgrade was initiated and will be completed in

Figure 5. CatalinaIsland Standard Range(USCC)—SurfaceCurrent Mapping(SCM) site installedwith recommended con-figuration: stainless steelenclosure with air condi-tioning, UPS powerbackup, and wirelesstelemetry.


March 2008. Once completed, all UCSB operated SCM sites will be able synchronize with other SCM sitesas necessary. SCCOOS staff anticipates continued on schedule delivery and installation.

Task A.5 Standard Operating Practices


• Provide hourly radials in real-time to operator accessible website.

• Download and archive lower level spectral data for detailed analysis and reprocessing capabilities.

• Develop and improve standards for antenna operation and maintenance. Conduct beam pattern meas-urements where needed.

Deliverable for December 2007: Progress report of any outstanding maintenance, telemetry, or operationissues.

Progress for task A.5SIO SCCOOS programmers have developed detailed system diagnostic utilities from the available meta-

data, allowing for a quick look at data transfer latencies, system health, data reliability, and error estimates.SCCOOS staff have drafted the technical document: Deployment & Maintenance of a High-Frequency Radar forOcean Surface Current Mapping: Best Practices (2007).

Maintenance and CalibrationFollowing the activation of the Diablo Canyon long range and high-resolution system, Cal Poly techni-

cians began talks with PG&E regarding calibration of this SCM site with a boat antenna pattern measure-ment (APM). Logistics of the APM were complicated by a security zone surrounding the Plant, which pro-hibits vessels from entering the waters within two nautical miles of the Diablo Canyon Power Plant (DCPP)(viz. United States Code of Federal Regulations, Title 33, Navigation and Navigable Waters, §165.1155Security Zone; Diablo Canyon Nuclear Power Plant, Avila Beach, California). Staff successfully negotiatedwith PG&E staff to allow an APM of DCSR within these waters; on October 12, 2007 PG&E provided itsown captain and vessel, free of charge, to perform the APM.

Figure 6. Diablo Canyon Standard Range (DCSR)—Radial surface current velocities measured by DCSR before the APM was applied (leftpanel) and one week later with the APM applied (right panel). Note the more realistic distribution of the vectors with the APM applied.


HF Radar ModificationsUCSB researchers have pursued the improved operational performance of SCM site through improve-

ments in hardware, operator training, and software research and development. UCSB staff developed adipole Tx antenna, and improved (tunable) monopole antenna, which has significantly improved SCM siteperformances.

The Santa Cruz Island site presented several technical challenges. The island is almost entirely withoutinfrastructure, with the exception of a site operated by the U.S. Navy, which is powered from a large solararray. Because of obvious cost savings of using existing infrastructure, it was decided to try operating at thesite despite it being a minimum of 750 m to the water. The distance from the water created a need to maxi-mize the transmitted signal power. This was accomplished by using a custom made, tunable di-pole antenna,which allowed us to operate the site successfully. A second challenge was imposed by the need to cool thetransmitter while consuming less power than a typical air conditioner. To accomplish this, a water-coolingjacket was designed and built by an undergraduate engineer using work-study funds. A final technical chal-lenge overcome at the site was the use of an 802.11b wireless network to telemeter data to UCSB, despite the30 mile separation. Identifying the proper equipment for the task was accomplished with input from the SantaBarbara Amateur Radio Club. The Santa Cruz Island site remained operational until permission negotiationsrequired temporary offline status. UCSB personnel expect to have completed permissions in early 2008.

Support from other agenciesFunding through NOAA supported UCSB and SIO technical personnel to work on improvements in

quality assurance/quality control procedures for SCM data. NOAA has also supported SIO efforts to devel-op the software architecture for a national network of HF radar. As described above, COCMP benefitsdirectly from this work

Reliant Energy maintained and repaired an electric circuit at our Mandalay Generating System SCMsite, which has greatly increased its reliability. Based on previous experience, the value of this electricalmaintenance is about $2,000.

UCSB provides power to the Coal Oil Point SCM site at a cost of about $2000 per year.

Funding for HF radar operations and analysis was obtained as part of the NSF-funded Santa BarbaraCoastal Long Term Ecological Research (SBC-LTER) project.


Task B.1Wave & Current Observations

2007 Work Program for Task B.1

• The surf zone component of the San Pedro/Huntington Beach (HB06) observation program was suc-cessfully completed in November 2006. In 2007, these observations will be quality controlled, and(owing to the limited funds available) partially analyzed. The highest analysis priority is to use theobservations to calibrate and improve our operational model for real-time waves and currents (TaskB.3). Additionally, funding permitting, we will begin to analyze our COCMP-supported drifterobservations, an important step in our long-term goal of understanding the transport and mixing ofsurf zone pollutants.

Deliverable for December 2007: Present results at meetings, and provide the calibrated alongshore currentmodel to Task B.3 for implementation.

Progress for Task B.1The 2007 project goals were achieved. Surf zone observations collected as part of the San

Pedro/Huntington Beach observational program (HB06, completed in November 2006) have been qualitycontrolled, and are freely available. The observations have been used to calibrate and improve our opera-tional model for real-time waves and currents (Task B.3), and in ongoing studies of surf-zone turbulence andmixing, and of nearshore Chl distributions. Preliminary analysis of HB06 observations will be presented infour talks at the Spring 08 Ocean Sciences meeting, and is described in two student first-authored journalarticles (submitted).

Support from other agenciesONR and NSF support for analysis of COCMP-supported drifter observations at HB06 is a sub-element

in new multi-year awards (concerning nearshore transport and mixing) totaling approximately 1.6M. HB06observations and preliminary results are also being used to motivate funding for additional hardware to beused in future studies of nearshore currents and mixing on California beaches. A 200K proposal to ONR fora 2nd dye sampling jet ski is pending. An approximately 50K proposal to provide real-time estimates of thetransport and mixing of pollutants in the surf zone at the Santa Ana River mouth in Huntington Beach ispending (NOAA).

Task B.2 Transition Zone Observations - Drifter Deployment


• Bin surface current velocities derived from drifters and compute mean and variance ellipse maps.Compare drifter statistics with HF radar data once HF radar data has been processed with measuredantenna patterns and data is qa/qc’d.

Deliverable for December 2007: Submit summary analysis report of HB06 field deployment data.

B. ESTABLISH NEARSHORE AND SURF ZONE OBSERVATIONSCollaborating Program Scientists: Bob Guza (SIO), Falk Fedderson (SIO), Mark Moline (Cal Poly),Carter Ohlmann (UCSB), Dan Rudnick (SIO), William O’Reilly (SIO)


Motivation and GoalsThe nearshore transition zone, defined as the region outside the surf zone to ~2 km offshore in water

depths of 10-50 m, is poorly observed. This region lies beyond that of typical surf zone experiments, butinshore of the region typically resolved with HF radar instrumentation. While moorings have beendeployed in the nearshore transition zone, mooring data give only fixed-point measurements, and do notresolve the complete time and space evolution of the flow field. The societal relevance of the transition zoneis clear, as it is heavily utilized both commercially and for recreation. Continuous in situ observation of thetransition zone currents is difficult, but is becoming increasingly feasible as several technologies improve.

The overarching goal of the transition zone drifter deployments is to observe the surface flow field onshort time (30 minute) and space (100 meters) scales. These data will be used to better understand the tran-sition zone surface current physics, for validation of remotely sensed high frequency (HF) radar data, and forvalidation of numerical model results. Little is known about the performance of HF radar and coastal circu-lation models in the transition zone. Goals for 2007 relate to the processing, synthesis, analysis, and inter-pretation of the HB06 drifter data.

Progress for Task B.2A total of 16 drifters were repetitively (when drifters reached the surf zone they were retrieved and

reset) deployed off the coast of Huntington Beach, CA on 15 days during the 15 September to 15 October2006 intensive observation period. A total of 262 drifter tracks were sampled. Each track consists of positiondata (accurate to a few meters) recorded every 10 minutes for between 1 and 5 hours. Surface current veloc-ities are simply computed from changes in position over a ten minute period. During 2007, the drifter datawere synthesized to give a general picture of the observed surface current physics in the transition zone.

Drifter tracksA total of 262 drifter tracks were sampled on 15 days during the 15 September to 15 October 2006 peri-

od. The raw data and derived products have been archived on the web at http://www.icess.ucsb.edu/drifter/HB/index.php. Drifters generally movedonshore and/or down coast with velocitiesbetween 4 and 30 cm s-1 (Figure 7). Thelargest velocities were in the down coastdirection at more that 40 cm s-1 on 2 and4 October. Only on 9 October did theentire fleet of drifters move up coast.Offshore movement of the entire drifterarray was never observed. Drifters justbeyond the surf zone occasionally becameentrained in rip currents and movedslightly offshore intermittently.

Figure 7. The complete set of 262 drifter tracks collected during the HB06 experi-ment. Green dots indicate starting positions, red +’s give ending positions, and thesmall blue dots are the drifter positions every 10 minutes.


Mean velocities and varianceAverage velocities computed from all drifter observations are between ~5 and 20 cm s-1 in the onshore

and down-coast direction (Figure 8a). Corresponding variance ellipses are oriented primarily in the alongshoredirection for the most offshore region, and are nearly circular over the inshore region just beyond the surf zone(Figure 8b). For the offshore region, variance values are of the same order as mean values. Variance values justbeyond the surf zone are a few cm/s and generally only a fraction of the corresponding mean values.

Across-shore and alongshore velocity shearsTwo of the most interesting findings to date are the pronounced across-shelf shear in the alongshore cur-

rent (Figure 9a), and a region of surface convergence just beyond the surf zone (Figure 9b). These flow fea-

Figure 8b. Variance ellipses corresponding to mean values shown inFigure 2a.

Figure 9b. As in Figure 3a for the on-shore component of velocity.Figure 9a. Alongshore velocity as a function of water depth or distancefrom shore. The 20 m depth contour is located roughly 2 km from theouter edge of the surf zone. Velocities are computed with all drifter datacollected within 2.5 meter depth bins, a value selected to give a somewhatuniform distribution of observations. Error bars show +/- standarddeviation values for velocity observations within a depth range.


tures act on scales less 1 km, suggesting that they might not be resolved in HF radar derived surface currentobservations and coastal circulation model results. The features are important for many applied problems inparticle (e.g. pollutants, larvae, objects lost at sea) tracking. The observations suggest that water parcels mov-ing toward shore don’t continue their swift movement toward the beach, but rather converge just beyondthe surf zone and then only percolate into surf zone waters. The observations show that the alongshoremovement of particles is a strong function of the distance from shore within the first few kilometers from thebeach. These results are being disseminated to both the SCCOOS HF radar and modeling communities foruse in validation procedures.

Task B.3 Modeling Wave Evolution & Currents to Nowcast Surf zone Currents

(Santa Monica and Huntington Beach Region)


• Preliminary results from HB06 show that our operational models for waves (seaward of the surf zone)and alongshore currents (within the surf zone) are usually reasonably accurate. However, the wavescomponent of the model does not include seas generated by locally strong winds, and in these casesthe associated model for wave-driven alongshore currents also necessarily fails. To the extent possiblewith the available funds, we will include local winds in the wave and current models for the SantaMonica and Huntington Beach regions.

• Real-time estimates of surf zone waves and current for a 4.5-km reach at Huntington Beach, alreadyavailable at http://cdip.ucsd.edu/hb06/ using interim models, will be upgraded to use improved mod-els (Task B.1). Additionally, the model coverage will be expanded to include the Santa Monica andHuntington Beach regions.

Deliverable for December 2007: Operational, real-time models for waves and surf zone currents in the SantaMonica and Huntington Beach regions.

Progress for Task B.3The 2007 project goals were achieved. Preliminary results from HB06 showed that an operational

model for waves (seaward of the surf zone) and mean alongshore currents (within the surf zone) were usual-ly reasonably accurate. However, the predicted currents were inaccurate when local winds had a strongalongshore component. Locally generated wind-seas have been included in the newly developed regionalwaves model, thus improving the agreement between observed and modeled surf zone currents.

Nowcasts and forecasts of surf zone waves and current for a 4.5-km reach at Huntington Beach,http://cdip.ucsd.edu/hb06/ now include local wind seas. The online model coverage for surf zone currentsis being expanded to include the Santa Monica and Huntington Beach regions (rollout anticipated 1 Apr2008). Coverage of the long, sandy beaches in Southern California is expected by the end of 2008 (Figure 7).

Support from other agencies CDIP (supported by CDBS and USACE) provides the regional wave observations that drive the surf

zone models.


Task B.4 Northern and Central California Nearshore Data


• Nearshore wave predictions for Monterey Bay have been validated by Naval Postgraduate Schoolinvestigators and the results presented at the 2006 AGU Meeting. Generally good agreement wasfound between the model and nearshore buoy measurements for swell waves (wave periods greaterthan 8 seconds), however, the model underpredicted local generated "sea breeze" waves owing to thelarge distance between the initializing NOAA buoy offshore and the validation site in the SE cornerof Monterey Bay. This suggests an additional directional wave buoy is needed (within or close toMonterey Bay) to enhance model predictions of short period local seas in this region.

• The nearshore wave predictions will be expanded in 2007 to include other sections of the Central andNorthern California coastline that are impacted by high surf. This data will be available on theWWW, and provided to Naval Postgraduate School investigators for use in their longshore currentmodel.

Deliverables for December 2007: Operational, real-time wave modeling of selected high impact sections ofthe Central and Northern California coast.

Progress for Task B.4The 2007 project goals were achieved. Real-

time, high-resolution wave products are availablefor selected high impact sections of the Centraland Northern California coast. Nearshore wavepredictions are now operational for Santa Barbara,Monterey, Santa Cruz and San Francisco Counties(Figure 2). Eureka, Crescent City and Fort Braggwill be added in 2008 (Figure 1). The NavalPostgraduate School is downloading predictions inreal-time for the southern half of the MontereyBay coast (Monterey Harbor to Moss Landing). Inaddition, the wave predictions are available in betatest mode on the CDIP site http://cdip.ucsd.edu/?moplist=Overview&xitem=overmap. A publicportal to the new nearshore data is under develop-ment.

Support from other agenciesCDIP (supported by USACE, CDBW) initial-

izes and runs the operational, network wavemodel. The Northern California portion of theCDIP wave network annual operating budget isabout $392,000. New CDIP Wave Buoys($100,000 from CDBW), deployed in Monterey

Task C.1Underway CTD

2007 Work Program for Task C.1

• Evaluate the newly-commercialized underway CTD operational deployments.

• Continue operations of the underway CTD system across the San Pedro Channel in the LA region.

• Conduct Quality Assurance / Quality Control (QA/QC) of data.

Deliverable for December 2007: Operation of the underway CTD and submission status report of underwayCTD, respective data retrieval and QA/QC.

Progress for Task C.1As planned, a newly commercialized underway CTD (uCTD) system was purchased from

OceanScience, of Oceanside, CA in 2007. The system has been significantly improved since the first versionthat had been in use since 2005. Major improvements include: 1) a better, more automated winch with levelwind; (2) data is downloaded more rapidly via a wireless “Blue Tooth” data link; (3) a new suite of conduc-tivity, temperature, and pressure sensors. The sensors are manufactured by SeaBird Electronics of Bellevue,WA, and will be calibrated annually by that company. This will ensure consistent, accurate calibrationthrough time.

Preliminary testing of the new uCTD has been very successful. Field operations are simpler and will beeasier for the marine technicians to maintain over time. In particular, the winch operation is less demandingand data downloads are faster.

C. ESTABLISH SUBSURFACE OBSERVATIONSCollaborating Program Scientists: Libe Washburn (UCSB), Russ Davis (SIO)


Underway CTD operations were conducted across the San Pedro Channel as planned through February2007. Operations were halted due to mechanical problems with the R/V Sea Watch, the vessel used for oper-ating the uCTD. Additional delays occurred when the USCG changed the certification of the Sea Watch sothat it could no longer transport supplies to Catalina Island. Personnel at the Southern California MarineInstitute, the ship’s operator, have appealed the decision. Since then, trips have been planned and cancelledduring the appeal process. This has been an extremely frustrating situation, given the success of this project sofar. PI Washburn is working with USC personnel to resume operations, possibly from another vessel.

Quality assurance and quality control procedures were developed for data collected with the newuCTD. The principal data products from the uCTD operations are vertical profiles of temperature and con-ductivity versus pressure at 6-8 stations, both outbound and inbound, across the San Pedro Channel. Transitsrun between San Pedro and the Wrigley Marine Science Institute on Catalina Island. Other data productsinclude: 1) profiles of derived variables such as salinity, density, and buoyancy frequency; 2) plots of verticalproperty sections; 3) maps showing station locations in relation to coastlines and bathymetry. Raw data aretransmitted to UCSB soon after each cruise. These data are then processed and made available for download-ing at a website at UCSB (http://www.icess.ucsb.edu/iog/uCTD/index.php), and at the SCCOOS website(www.sccoos.org).

Task C.2 Bight-Scale Monitoring—Glider Operations

2007 Work Program for Task C.2

• Continue (under COCMP funding) to maintain hopefully continuous operation on CalCOFI Line 90(Dana Pt.) sampling temperature, salinity, currents, and phyto- and zooplankton abundances.

• Continue (under other funding) similar coverage on Line 80.

• Begin (under COCMP funding and in collaboration with Francisco Chavez of MBARI) to use a sin-gle glider to occupy a repeated line off Monterey Bay near CalCOFI Line 67. This will extend cover-age to describe, on seasonal time scales, the changes in physics, phytoplankton and zooplankton to thearea between Monterey and San Diego.

• Continue quality control of the data, begin providing the data in real-time to the ROMS modelingeffort, and begin retrospective analyses of both HB06 and the repeated offshore lines.

Deliverable for December 2007: Submit a status report on the missions enumerated above. Maintain the pub-licly accessible data archive. Provide simple scientific summary of results from the first three years of work.

Motivation and goalsThe COCMP underwater glider program addresses the physical and ecosystem variability associated

with climate variability in the California Current and Undercurrent and in the nearshore waters. The ini-tial goal is to establish a baseline for the seasonally varying physical and biological structure of these watersagainst which changes can be measured. The sampling goal is to maintain approximately continuously oneunderwater glider on CalCOFI Line 90 that intercepts the coast near Dana Point, Line 80 that comes ashorenear Point Conception, and Line 67 that extends west-southwest from Monterey.

The main physical phenomena believed to cause ecosystem variability along the California coast are (a)modulation of the supply of nutrients to the phytoplankton base of the food web, (b) physical transport ofspecies with different geographical distributions, and (c) changes of factors like temperature that influence


the viability of individual species. To observe the properties affecting these processes, the SIO glider fleetuses temperature, salinity and velocity observations to describe physical factors like alongshore advection,upwelling, and mesoscale eddies, fronts and jets. Chlorophyll-a fluorescence is an indicator of changes inphytoplankton abundance and the acoustic backscatter strength of the velocity-measuring ADCP trackszooplankton abundance. We are developing, under separate funding, a nitrate sensor installation for thegliders to complete observations of physical, nutrient, and biological variability.

Within the SCCOOS environment we look to two methods of analysis to convert the glider time seriesinto information that can be used to manage human activities that, in conjunction with climate forcing,stress marine ecosystems. Most immediately, analysis of glider observations will provide case studies and sta-tistical descriptions of the subsurface variability connecting physical climate and changes in ecosystems.Ultimately, dynamically consistent ocean models, like ROMS, constrained by ocean observations, areexpected to provide the most complete relations between climate and ecosystems. By observing subsurfacephysics, and also biological variables within the California marine environment, gliders complement thedescriptions of surface currents obtained from the SCOOS surface HF radar array and the less frequent butmore complete shipboard physical, chemical and biological sampling obtained from CalCOFI.

Progress for Task C.2During 2007, the program reached its full strength, with continuation of continuous sampling on Lines

80 (implemented in May 2006), Line 90 (begun October 2006) and implementation of repeated samplingnear Line 67 off Monterey. The following table gives time periods of each cruise on the three CalCOFI linesduring 2007.

20 Nov 07-10 Jan 08

In normal operation we plan for four cruises of approximately 90 days each for each year (as occurredon Line 90). Sensor failures caused premature recovery of two cruises off Point Conception (Line 80). Wehave not yet received the third budgeted glider for COCMP work, and as a consequence there was a gapbetween deployments off Monterey while we performed refueling and maintenance on the one glider avail-able for that operation. We now have enough gliders to maintain approximately continuous sampling on allthree lines through 2008, so long as there are not losses.

All cruises supported depth, temperature, salinity, acoustic velocity shear, chlorophyll-a fluorescence,and acoustic backscatter measurements. The data are available in raw form in real time throughspray.ucsd.edu, and are assimilated by the ROMS model syntheses prepared at JPL. All data from cruisesrecovered before December 2007 have been quality controlled and archived. These archived data can beplotted through the Spray web site, and are presently ingested into the SCCOOS data system. The ingestionis able to automatically determine if these data are from an active or completed mission. Data retrieval and


display tools are being developed for accessing andpresenting SPRAY glider data on thewww.sccoos.org website.

A summary of results from the first 18months of measurements on Lines 80 and 90 wassubmitted to Limnology and Oceanography by Davis,Ohlmann, Rudnick and Hodges. This disclosesthe seasonal differences between the upwellingseason, which peaks in spring, and the wind relax-ation season, which peaks in fall and winter. Alsodefined by the absolute velocity measurementswas the poleward flowing CaliforniaUndercurrent (see Figure 12), which is strong overthe shelf, particularly in winter, but was found tobe unexpectedly ubiquitous throughout the Bight,and common offshore of the Channel Islands. Thisrepresents a surprisingly strong poleward advec-tion that must be an important factor in howspecies with planktonic life stages remain offCalifornia for significant periods in the face of thepersistent equator-ward near-surface advectionby the California Current.

Less expected wasthe observation of a per-sistent upper-ocean eddysouthwest of Pt.Conception (see Figure13). While we did nothave continuous cover-age, the eddy, or a recur-rent twin, was observedin the same location onsuccessive transects overa six-month period. Thetemperature, salinity andchlorophyll-a inside theeddy were intermediatebetween the rich SantaBarbara Channel waterfound closer to shore andthe nutrient-depleted

offshore waters (see Figure 14). More surprising was the concentration of zooplankton (as indicated byacoustic backscatter) near the edges of the eddy. The persistent Line 80 eddy is an example of the mesoscalestructure that dominates much of the glider data, and which is believed to be as important to climate-ecosys-tem coupling as are connections occurring on the large scale.

Support from other agenciesThe repeated glider sampling involves funding contributions from four separate sources. COCMP has

provided two gliders and a third is on order. COCMP also supports the continuing maintenance, deploy-ment/recovery, and data management functions, primarily on Lines 90 and 67. The Gordon and Betty MooreFoundation initiated the combined physical and biological sampling on Line 80 as an adjunct to theCalifornia Current Ecosystem Long Term Ecological Research (LTER) site, and is underwriting transition ofthe ISUS nitrate sensor to a glider installation. NOAA funding through the Office of Global Programs andthen the Climate Observations Program helped through 2006 with development of the Spray glider and theprocedures and suite of sensors used today. Finally, the Coastal Services Center of NOAA has supportedcoastal glider sampling with Spray through 2007, primarily on Lines 90 and 93. We have asked the CoastalServices to support some ongoing glider operations beginning in 2009.

D. ESTABLISH REGIONAL OCEAN MODELINGCollaborating Program Scientists: Jim McWilliams (UCLA), Bruce Cornuelle (SIO), Yi Chao (JPL)

Task D Establish Regional Ocean Modeling

Task D.1, D.3.2 Model Research and Development, Synthesis of SCCOOS Data Fields and Ocean Modeling

• Evaluate the ROMS forward model by comparing simulations with available observations and adjustthe ROMS configuration if necessary

• Improve the ROMS tidal simulation by adjusting the tidal boundary conditions and bottom topogra-phy; evaluate the tidal ROMS performance by comparing simulations with the tide gauge measure-ments and satellite altimetric observations


• Refine the HF radar data assimilation scheme by constructing more realistic error covariance

• Develop the necessary web-based infrastructure and implement the MM5 mesoscale atmosphericmodel ROMS tidal-resolving circulation model for real-time forecasting and demonstrate its real-time operations

• Define and produce the model-based products for practical applications, in collaboration with otherpartners and application users

Deliverables for 2007:

• A real-time operation of ROMS with fully resolved tides and assimilation of HF radar and other datasets.

• Model derived products for applications users, in collaboration with COCMP partners and applica-tion users.

• A web site portal hosting all the model output and images that will be connected to the COCMP website and SCCOOS/CeNCOOS web sites

• Publications of the ROMS modeling, data assimilation and real-time forecasting.

Progress on Task D.1The ROMS was applied to the simulation of

the Southern California Bight (SCB) circulation.The forward model results were verified withobservations from tidal gauges, CalCOFI data,AVHRR SST and T/P SSH data and mooringdata. The ROMS error covariance has beenrefined with a particular focus on the HF radardata assimilation. We are in the process of evalu-ating the ROMS hindcast/nowcast/forecastfields by comparing them with available observa-tions.

Tidal gauges: The model was forced by the eighttidal constituents. The barotropic tidal ampli-tudes and currents along the open boundaries arefrom the TPXO.6.2 (OSU Global Tidal InverseSolution). Six tidal gauges are available in theSCB. Figure 15 shows the time series of the SSHmodeled and observed at the six tidal gauges.The statistic results of the tidal amplitudes andphases in terms of different tidal constituents aredisplayed in Figure 16. The good agreement pre-sented in the two figures demonstrates thatROMS simulates well the barotropic tidal sig-nals. Comparisons between the ROMS nowcast/forecast and the tide gauge measurements are produced inreal-time and displayed on the ROMS portal.

Figure 18. The SST anomalies in the summer andwinter from the model (top) and AVHRR (bottom).


CalCOFI data: There are six CalCOFI cruiselines (stations) in the SCB. In this reportwe chose Line 87 to present the evaluationof the model. Line 87 crosses the center ofthe SCB. Figure 17 shows the mean verti-cal profiles of salinity and temperature insummer and winter. A comparison of themagnitudes, spatial structure, and seasonalvariation between the model results andthe data shows strong similarity.

AVHRR SST: The seasonal SST anomalies fromboth the model and the AVHRR data arecalculated based on the period 1996-2003,Figure 18. In the summer and winter, theSCB experiences both positive and nega-tive anomalies; there are bigger anomaliesnear the coast than in the open ocean.

T/P SSH: only three T/P tracks pass the SCBdomain. The tracked SSH data were usedto study the inter-annual variability in theSCB. Figure 19 shows the time series ofthe SSH anomalies along the three tracks.The positive anomalies in both the modeland the T/P data during 1997-1998,when the ENSO event occurred, can beclearly seen.

Mooring Data (Synoptic Event): a strongupwelling event took place in the SCBduring March 2002. The forwarded modewas used to study the event. The SST timeseries at the Santa Monica Mooring wereplotted. The SST drops by 4.0 degree in 2-3 days. The model successfully simulatedthe extreme event (Figure 20).

Progress on Task D.2The UCLA group is utilizing two mesoscale atmospheric models simultaneously for meteorological fore-

casts over the SCCOOS domain. The first is MM5, the model used initially by the UCLA group to supportSCCOOS. MM5 has been run operationally in near real-time at UCLA for roughly two years. The othermodel is the WRF (Weather Research and Forecasting model), a model fast becoming the community stan-dard in regional atmospheric modeling. Our goal is to move the modeling basis of SCCOOS forecasts fromMM5 to WRF. WRF has been continuously running the past few months in parallel with the MM5 fore-casts to test its computational stability, and to optimize physical and dynamical choices. Both MM5 and WRFare initialized daily with 06Z national forecasts from NCEP, and run for 48 hours. The testing of WRF hasbeen successfully completed, and we are currently in the process of transitioning the near SCCOOS real-timeforecast from MM5-based runs to WRF-based runs. By the end of January 2008, all the forecasts will be donewith WRF. The wind model will continue to beoperated at high resolution within the southernCalifornia domain and provided to the ROMS oceanmodeling system

Progress on Task D.3UCSD has begun to transition the improved

(weighted least squares) velocity estimation algo-rithm to the community. There is still some docu-mentation and explanation needed for full accept-ance.

Upgrades continue for the mapping methodsfor the HF coastal radars, and efforts continue torefine estimates of the covariances of velocity fromobservations. For compatibility with the JPL3DVAR effort, UCSD has added the capability ofcomputing covariances in terms of the Helmholtzdecomposition (velocity potential and streamfunc-tion) (phi and psi) in addition to u and v. Observedcurrents are being separated into components withdistinct physical sources: wind-driven, tidal, and lowfrequency, for example. Each component is expectedto have independent statistics, and we are workingto estimate covariances for each from observations.These covariances will provided the basis for fillingHF radar data gaps and for short-term surface cur-rent predictions. These gap-filling techniques havebeen applied to surface currents measured in the SanFrancisco Bay region, and were used to estimate tra-jectories of the oil spilled during the Cosco Busanincident. Mapping methods used for the Southern

Figure 21 (above); Figure 22 (below)


California bight radars to OI from unweighted least-squares are now upgraded, and real-time mapping of thelong-range radar network, including estimates of streamfunction and velocity potential, has been implement-ed. Figure 21 and Figure 22 show the objectively interpolated map of ocean currents for southern Californiaand the streamfunctions of the velocity field, which also identifies the presence of eddies, an importantdynamical feature, which can extend the lifetime of waterborne constituents (e.g., biota, contaminants, andsediments). These computations are updated hourly and available on the www.sccoos.org website.

UCSD is working on statistical-dynamical wind-driven current models for inferring the wind-drivencomponent of current as added information for the mapping, and continues to work on implementing4DVAR ROMS assimilation (using initial conditions as the only control) in the Southern California region.ROMS tracer dispersion modeling continues, using downscaled winds from the California reanalysis usingthe Regional Spectral Model (RSM). These experiments and the comparisons of the reanalysis winds withobservations show that better wind forcing products are needed. Getting wind from the MM5 SCCOOSruns that JPL has been using is being explored.

As a complement to the ROMS assimilation, UCSD has implemented MITgcm 4DVAR (adjoint) assim-ilation of radials for the San Diego region on a 1 km grid. The MITgcm 4DVAR assimilation has initial con-ditions, boundary conditions, and forcing as controls, and produces dynamically consistent evolving fields.The comparison of the more stringent 4DVAR assimilation with the JPL 3DVAR should provide insightsinto the resolving power of the observing network, and the adjoint sensitivity can be used to evaluate obser-vation strategies.

In pursuit of finer spatial scales in the nearshore region, UCLA has developed a new model configurationspanning the continental shelf and slope in Santa Monica Bay, Palos Verdes peninsula, San Pedro Bay, and thesite of the Huntington Beach experiment in 2006. A realistic, shelf-scale, high-resolution regional experimentwith ROMS for Palos Verde (PV) Shelf, California, has been carried out. Energetic submesoscale eddiesdetached from the PV cape, and the “filament" structure is visualized by meandering salinity fronts right at theshoreline (Figure 23). Grid refinement from 1-km (left panel in Figure 23) to 200-m resolution (right panel)appears to introduce more intense horizontal SSS gradient and associated eddies. The offshore extent of the fil-ament is computed to be of O (1 km), and it differs from a classical view of offshore transport process by rip cur-rent, undertow, or shear waves associated with shear instability in alongshore currents. Headland wake insta-bility, nearshore wave-driven currents, barotropic shear instability within the upwelling zone, and baroclinicinstability along the fronts are considered to be key processes in generation of these submesoscale eddies and

variability. A related scientific processstudy of submesoscale currents in acoastal upwelling regime has also beencarried out (Capet et al., 2008a, b, c).

E1. Information Technology Development

Work Program for Task E.1

• Continue the networking of real-time HF radar systems.

• Deploy Linux based system portals at HF radar nodes of operation. Portals serve as onramps to thereal-time data system.

• Maintain and expand the capabilities of a Linux based system portal deployed at JPL to act as an HFradar data archive and data system off-ramp. This system is located at JPL to facilitate data assimila-tion into the ocean model.

• Manage the flow of data from the distributed SCM sites, including data storage, data archives, anddata access.

• Continue the development of prototype user interfaces to COCMP funded observations.

Deliverable for December 2007: Interfaces for accessing COCMP funded observations. Status report of datasystem including the development and adaptations made to the system, difficulties experienced, and achieve-ments. Present summary of data system interfaces.

Progress on Task E.1SCCOOS supported programmers began coding to restructure the real-time data storage system. As the

data system continues to increase in size, data queries and data serving can become slow for the user. Effortsare underway to reorganize the database schema and storage methods. Individual data streams require a ded-icated database with a shared metadata catalog. Parsing the SCCOOS database causes more complex relation-ships between parameters for querying across multiple datasets, but significantly improves access and stor-age requirements by limiting a single large system.

Through continued collaboration with other program participants, HFR data is currently being sharedfor the generation of data products benefiting the public. SCCOOS continues in its implementation of theCOCMP HF radar dataexchange for all of California,and has made significantadvances in building HFradar data transport for theregion. SCCOOS supportedprogrammers also continueto develop HF radar metada-ta, and to implement a net-work Common Data Format(netCDF) for data dissemina-tion of statewide HF radarsurface current maps.

A total of 10 new HFR sites were added to the near real time data acquisition and processing system fora total of 45 sites within California. An additional data acquisition computer (Portal) was deployed atUniversity of California, Santa Cruz (UCSC) (07/25/2007). There are now five operational portals deployedin California, and one that is ready for integration at the University of Southern California. The previousdeployed portals are operational at University of California at Santa Barbara (UCSB) (2006/01/30), SanFrancisco State University (SFSU) (2006/04/11), California Polytechnic State University (Cal Poly)(2006/11/15), and Scripps Institution of Oceanography (SIO). The UCSC High Frequency Radar Network(HFRNet) Portal was brought on-line to serve data from UCSC/NPS HFR sites on December 5, 2007. Theinstallment of this Portal lightens the load on the SFSU Portal, providing a larger buffer for each system. Thislarger buffer effectively enables the system to tolerate longer network outages. The SFSU portal remains inoperation, and continues to serve data from SFSU and BML HFR sites. Future HFRNet developmentincludes deployment of a data repository computer (node) at UCSC and access to total vector data. Currently,data access is available through near real-time online Google map graphical displays. SCCOOS data manage-ment includes continuing development at the radial data level, focusing on schema development and meta-data extraction for further diagnostic information and quality control.

In the first quarter of 2007 SCCOOS provided feedback for the newly created Integrated OceanObserving System (IOOS) Observation Registry, fol-lowing a request for input from RegionalAssociations. SCCOOS programmers provided anXML document designed to meet minimum FederalGeographic Data Committee (FGDC) required fields(Content Standard for Digital Geospatial Metadata(CSDGM) core requirements), and endeavored toconform to both IOOS registry requirements andFGDC metadata standards. Programmers alsodetailed a best-fit 1-to-1 relationship between theIOOS registry specification and the FGDC specifica-tion. These standards have now been expanded to afull FGDC metadata document, and submitted to theIOOS Data and Communications SteeringCommittee (DMAC) in October 2007. The full sub-mission can be found at ioosdmac.fedworx.org, withthe guest login: High Frequency Radar SurfaceCurrents.

Deliverable for December 2007: Progress report for COCMP funded product development efforts.Workshop dates, summary of user interactions, and examples of prototype products.

Progress for Task E.2The SCCOOS data management team continued to improve existing and develop new products

throughout 2007. This year several efforts focused on facilitating data exchange with the Jet PropulsionLaboratory (a node was shipped on 2006/05/15) for HF Radar data assimilation into their modeling runs, anddevelopment of an interactive utility for visualizing model output. The modeling interface for the ROMSNowcasts currently reads the Nowcast NetCDF files directly, and can return on-demand cross-sections atany given time. A secondary interface emulates "virtual moorings," allowing a user to view a time-series ofROMS modeled output at a specific location over long time ranges. ROMS Nowcasts are data sets capturedat a specific time; by aggregating multiple nowcasts, data managers have been able to build a time-series (4thdimension) component into the visualization process. Stepping through multiple Nowcasts on the fly can besignificantly resource intensive. SCCOOS programmers have hand-selected targeted areas for these "virtualmoorings" located at the ocean outfalls along the coast. This allows time series to be pre-generated andspeeds the access time for end users.

In 2006, the SCCOOS data managementteam implemented a statewide Google maps inter-face for COCMP real-time surface current maps.The common interface has been deployed for bothSCCOOS (http://www.sccoos.org/data/hfrnet/)and CeNCOOS (http://www.cencoos.org/hfrnet/). The Google maps interface is interactive,allowing zoom in/zoom out capabilities, 25 houraverage current fields overlay, four resolutions ofcurrent vectors, and up to 24 hours of historicaldata. Beginning in October 2007, SCCOOS pro-grammers worked to expand and improve tilingcapabilities to accurately accommodate both thespherical Earth model and the WGS84 model.For most SCCOOS applications, this effort willnot affect data usage; however, for the purpose ofnavigational aids, the differences at high resolu-tion can be quite drastic. Tiling a map that was rendered in WGS84 without properly accounting for thesubtleties of the datum can cause errors up to tens of meters. After the correction, projection errors havebeen reduced to a few feet or less, depending on the quality of the original map. At this time, the tile gener-ation system requires additional development, as all tiled maps require customized scripts. Tiling is resource

intensive, and not all maps can be tiled in a reasonable amount of time. The data management team is con-sidering alternatives, such as generating on-demand products and caching. In 2007, HF Radar data hasaccounted for over 100 million tiles. Older tiles may need to be discarded after some time, and regeneratedon-demand. A tile management system will become necessary if multiple data sets are to become tiled.

Finally, SCCOOS programmers have continued work to improve the usability of the website by devel-oping a unified, map-based interface displaying assets from a variety of sources in an efficient and flexiblemanner. The interface takes the form of an integrated, full-window-sized map to maximize the active areaavailable to the user, and features an intuitive layering mechanism designed to tailor the display to the view-er's needs. Individual data assets are served in keyhole markup language (KML) to offer further integrationwith Google Earth in the future. This interface has already proved to be a valuable tool internally forSCCOOS, allowing for simple visualization of related data assets. Future work will allow for a greater vol-ume of real-time information to be available through this interface, and will also allow direct access to moreinformation about each data source from the asset map. SCCOOS plans to launch this map interactively onthe website in early 2008.

Surface Current Mapping at PG&E’s Diablo Canyon Power Plant: Site Plan

PROJECT BACKGROUND The Center for Coastal Marine Sciences at California Polytechnic State University (Cal Poly), San Luis Obispo has been funded by the State of California through funds from propositions 40 and 50 to establish an ocean observing system along the central California coast to obtain real-time measurements of ocean surface currents. Cal Poly, along with a larger consortium of institutions, has formed the Coastal Ocean Currents Monitoring Program (COCMP), whose aim is to synthesize measurements of ocean currents into products that will provide a scientific basis for evaluating and improving management, guardianship of, and response to the ocean environment and its resources. Benefits derived from this program will include:

• Tracking and predicting the trajectories of pollution, including sewage releases and oil spills.

• Increased effectiveness of search and rescue operations.

• Increased efficiency in responding to natural hazards like storm surge and coastal erosion.

• Increased efficiency of maritime shipping. • Increased precision in weather and climate forecasts.

The backbone of this project is the installation of high-frequency radio (HFR) transmit and receive antenna systems at appropriately spaced projections along the coastline, so as to afford the systems an uninterrupted and overlapping field-of-view of the ocean’s surface. The Diablo Canyon Power Plant represents a unique location for the measurement of ocean surface currents, as it provides an ideal field of view, and is therefore an important component of this collaborative effort. SURFACE CURRENT MAPPING SYSTEMS The measurement principle for HFR surface current mapping systems is based upon transmitting radio waves and measuring the echo from the ocean’s surface. The radio waves are transmitted from an antenna on shore, scattered off the ocean surface, and subsequently received by another antenna next to the transmitter. The Doppler shift in the received radio signal allows the determination of currents at different ranges and angles in a radial pattern centered at the radio antennas. Combining overlapping measurements from multiple systems deployed along the coast allows determination in real-time of both direction and velocity of ocean currents. The Diablo Canyon Power Plant’s unique location will allow measurements of surface currents to be made out to 150+ km, allowing the necessary overlap with adjoining systems.

HFR Antenna Specifications: Long-Range SeaSonde®, manufactured by CODAR Ocean Sensors of Mountain View, CA (Figure 1). Operation of the HFR antennas requires them to be placed within 200' of the water's edge. Both antennas require an unobstructed view of the ocean to function properly and must be separated by around 200'. The antennas need to be located well away (at least 200') from metallic structures and yet further from any antennas. Quantity: Two antennas, one transmit (Tx) and one receive (Rx):

• Transmit Antenna 1. 43 feet high, supported by guy wires 2. Radial ground elements at base of antenna 3. Broadcasts radio waves at approximately 5

MHz with an average power of ~60 W (about the power of a light bulb)

• Receive Antenna 1. 20 feet high, supported by guy wires 2. Four 4 foot radial elements are located at 12 feet 3. One 8 foot vertical element is located at 12 feet

Electronics Enclosure (Figure 2) • A weatherproof outdoor enclosure with nominal dimensions 36" high x 24" wide x 32" deep connected by coaxial cables to

the transmit and receive antennas. The enclosure will be used to house the transmit and receive electronics, universal power supply, and an air conditioner for climate control. Power requirements for the system are 120 VAC at approximately 800 W.

Marina Del Rey, CA 90292 3 July 2007 Mr. Rodriguez:

As discussed in a meeting with Mr. Wayne Schumaker, Mr. Carlos Zimmerman, and Chief Fernando Boiteux on July 2, 2007, the purpose of this letter is to provide details of an installation proposed for Nicholas Canyon Beach.

All parties present at the meeting agreed that an existing metal telephone pole would be a suitable location to install our instrument system (see figures below). The installation would require replacing an existing metal telephone pole with a new wooden pole. The new wooden pole would be installed adjacent to the existing pole, within the safety chain located on site. Once this pole is installed, telephone service wires for the lifeguard tower would be moved to the new pole. The metal pole would be cut off at about 3 ft. from the ground, capped, and painted yellow for safety. Cutting the pole off above ground prevents the need for digging it out of an unstable slope, and it was suggested that maintaining its height at about 3 ft. would be safer than cutting it off at ground level.

This installation would use a single antenna. The antenna would be installed on the new telephone pole, similarly to the installation shown in the attached figures. The computer and electronics would be housed in a small metal housing (approx 36”x30”x36” tall) set on the ground adjacent to the telephone pole. We would install a power meter adjacent to an existing meter, and run the power to our equipment underground. Running power underground to our equipment would require trenching across the road.

Please contact me if you have any questions or need additional information. I have also contacted Richard Mollica, the Associate Planner from the City of Malibu, whose approval will be required. Thank you,

Brian Emery, Staff Researcher Marine Science Institute University of California Santa Barbara, CA 93106-3060 805-893-8480 [email protected]

Synopsis

Organizations:

SCCOOS (Southern California Coastal Ocean Observing System)

COCMP (Coastal Ocean Currents Monitoring Program)

Funding:

California Clean Water, Clean Air, Safe Neighborhood Parks, Coastal Protection Act of 2002

(Proposition 40), and the Water Security, Clean Drinking Water, Coastal and Beach Protection

Act of 2002 (Proposition 50)1.

Primary purpose:

To provide essential information to agencies tasked with managing marine life resources, coastal

water quality, and coastal hazard issues.

General radio information:

Low power radio transmitters and receivers called SeaSondes. Radios operate in the range of 25

Mhz, operating at an average power of 40 watts. Three SeaSondes are located near Los Angeles

County Lifeguard Facilities: Dockweiler State Beach, Dan Blocker (Corral) and Nicholas Canyon

State Beach.

Safety Information:

1.) The level over which biological effects of radio frequency electromagnetic fields (EMF) may

occur is at a specific absorption rate (SAR) of 4 watts per kilogram (W/kg), as averaged over the

whole body. The SAR level of 4 W/kg is not based on a level where hazards will occur, but at a

level where a biological effect is measurable.

2.) Maximum Permitted Exposure (MPE) levels were then determined from this SAR level. The

MPE was determined by using factors of 10 and 50, producing MPE levels of 0.4 W/kg and 0.08

W/kg 7. (The maximum permitted exposure levels were set at one tenth (1/10th) and one fiftieth

(1/50th) the level where biological effects may occur.)

3.) According to ‘worst case’ estimates, the power density at all accessible locations near the

SeaSonde antenna is below the lower MPE of 0.08 W/kg. At a distance of 12 ft. from the

antenna, the power density is less than one third (1/3) this MPE level 16, or 150 times lower than

the level where biological effects may occur.

1. Benefits of the Southern California Coastal Ocean Observing System (SCCOOS)

SeaSonde systems installed at the Dockweiler Headquarters, Dan Blocker Beach, and

Nicholas Canyon Beach, are part of a larger, statewide program for observing surface currents in

the coastal ocean. The State Coastal Conservancy and the State Water Resources Control Board

initiated this program using voter-approved funds (from the California Clean Water, Clean Air,

Safe Neighborhood Parks, and Coastal Protection Act of 2002 (Proposition 40) and the Water

Security, Clean Drinking Water, Coastal and Beach Protection Act of 2002 (Proposition 50)) 1.

The program, called the Coastal Ocean Currents Monitoring Program (COCMP), is divided into

northern and southern consortia. The Southern California Coastal Ocean Observing System

(SCCOOS) is the southern component of the COCMP, covering the California Coast from the

Mexican border to Pismo Beach.

The primary goal of the COCMP and the SCCOOS is to provide essential information to

agencies tasked with managing marine life resources, coastal water quality, and coastal hazard

issues. Information from SCCOOS also benefits many segments of the population, from

regulatory agencies to beach goers. These benefits include improved warnings of coastal marine

health hazards, more efficient use of resources, safer marine operations, and a better

understanding of climate change. Emergency response agencies and the United States Coast

Guard Search and Rescue (USCG SAR) benefit from coastal ocean observations. Improved

monitoring of winds and currents is already, saving lives and money in US coastal waters. Recent

studies have shown that surface current monitoring can increase search and rescue efficiency by a

factor of 100% or more, greatly reducing risk to human life 2. Fishers, recreational boaters, and

commercial shippers, benefit from increased safety in coastal waters. Wave, wind and current

information help them plan their trips and minimize exposure to severe conditions at sea.

National security agencies may also benefit from surface current monitoring. Research is

underway to use the same current mapping technology for tracking vessels over the horizon 3.

SCCOOS surface current mapping sites consist of low power radio transmitters and

receivers called SeaSondes. These are commercial oceanographic instruments (manufactured by

CODAR Ocean Sensors, of Los Altos, CA) in wide use around the country. Presently about 90

sites operate around the country and about 78 report their data in real time over the internet 4.

These sites are the observational backbone of SCCOOS. The SeaSonde measures the ocean

current speed and direction from ~ 1 to 45 miles offshore. Maps of surface current from existing

sites are posted hourly, in real-time, on the SCCOOS (http://www.sccoos.org) web site. When

completed, the SCCOOS, along with the Central and Northern California Coastal Ocean

Observing system (CenCOOS, http://www.cencoos.org) will measure currents along the entire

California coast, giving scientists, researchers, and resource managers an unprecedented

understanding of the state and health of the coastal ocean.

2. Applicable levels for maximum permissible exposure (MPE)

SeaSondes measure ocean surface currents by transmitting and receiving low power radio

waves. The Federal Communications Commission (FCC) must license all radio transmitters and

other transmitters of electromagnetic fields (EMF). Under the National Environmental Policy Act

of 1969 (NEPA), the FCC must consider whether these transmitters affect the quality of the

human environment 5. Consequently, the FCC has adopted guidelines for human exposure to

EMF.

Since the FCC is not a research or medical institution, it relies on the findings of other

non-governmental organizations to determine the recommendations for safe levels of EMF

exposure. These organizations include the American National Standards Institute (ANSI), the

Institute of Electrical and Electronics Engineers (IEEE), and the National Council on Radiation

Protection and Measurements (NCRP). They have issued recommendations for human exposure

to EMF at radio frequencies (RF). The recommendations were developed after extensive reviews

of the scientific literature related to RF biological effects, and serve as a consensus standard

developed by representatives of industry, government agencies, the scientific community, and the

public 6. The FCC, the Occupational Safety and Health Administration (OSHA), and the

American Radio Relay League (ARRL) then adopted the recommendations.

To determine the safe levels of EMF exposure, the standards-setting groups based limits

for exposure on levels where recognized hazards may occur and then incorporate appropriate

safety margins to ensure adequate protection. The level over which biological effects may occur

is at a specific absorption rate (SAR) of 4 watts per kilogram (W/kg), as averaged over the whole

body. Maximum Permitted Exposure (MPE) levels were then determined from this SAR level by

using factors of 10 and 50, producing MPE levels of 0.4 W/kg and 0.08 W/kg 7. In other words,

the maximum permitted exposure levels were set at one tenth (1/10th) and one fiftieth (1/50th)

the level where biological effects may occur.

The SAR level of 4 W/kg is not based on a level where hazards will occur, but at a level

where a biological effect is measurable. The observation of a biological effect, in and of itself,

does not necessarily suggest the existence of a biological hazard. Furthermore, at a SAR level of

0.4 W/kg, a factor of 10 below the level where an effect is found, there is no evidence for

production of harmful biological effects. With regard to long-term exposure to RF below MPE

levels (0.4 W/kg and 0.08 W/kg), studies have failed to find evidence for a causal link to cancer

or any related condition 8.

The safety factors of 10 and 50 are used to define two tiered levels: the higher

controlled/occupational level, and the lower, uncontrolled/general population level. The lower

exposure level, (uncontrolled/general population) applies in situations “in which persons who are

exposed as a consequence of their employment … cannot exercise control over their exposure” 9.

Because the exposure is ‘uncontrolled’, these limits were set with the assumption of continuous

exposure. As long as the population/uncontrolled limits are not exceeded, indefinite, continuous

exposure is allowed 10. To restate, the MPE levels for uncontrolled/general population exposures

were set assuming continuous (24 hrs/day, 7 day/week) EMF exposure 11.

When discussing EMF and health, it is important to distinguish radio wave EMF from

other types of EMF that have short wavelengths and high energy content. For example,

microwave EMF is a hundred times more energetic than the energy of a SeaSonde radio wave 12.

Even shorter wavelengths of light, with much higher energy content such as ultraviolet (UV), are

called "ionizing" because of the way they interact with molecular structures, including human

tissue. The energy of radio wave EMF is not great enough to cause the ionization of atoms and

molecules and is therefore characterized as non-ionizing. It is important that radio wave EMF

and ionizing EMF not be confused when discussing biological effects of electromagnetic energy,

since the mechanisms of interaction with the human body are quite different 13.

3. How SCCOOS SeaSonde emissions compare with MPE levels.

The FCC publishes the MPE limits, discussed above, in terms of measurable EMF

parameters. The published Maximum Permissible Exposure (MPE) limits for uncontrolled

environments, applicable to a Seasonde transmitting at a frequency of 25 Mhz, are 14:

EMF Parameter___________MPE Limit_______

Electric Field strength 33 volts/meter

Magnetic Field strength 0.09 amperes/meter

Power Density 0.288 milliwatts/cm2

These parameters describe the same MPE limit in terms of three different measurable quantities.

For an area to be considered safe, measurements of these quantities (Electric Field Strength,

Magnetic Field Strength, and Power Density) must be below these levels. The quantities can be

related mathematically, and are equivalent.

SeaSonde emission levels can be calculated using readily available software from a

number of sources 15. These calculations tend to over-predict power density levels, but are useful

for "worst case" predictions. When performing these calculations, it is conservatively assumed

that ground reflections of radio waves occur. Given this assumption, calculations indicate that the

emission levels from SCCOOS SeaSondes are below MPE limits at distances greater than 6 ft

from the center of the antenna 16. Note that this distance is measured relative to the antenna

transmitting ‘element’. For SeaSondes, the transmitting element is the vertical whip, which is

typically at least 12 ft. from the ground. (At Nicholas Canyon, the antenna element is about 30 ft

of the ground). As with all EMF transmitters, EMF levels decreases very rapidly with distance

from an antenna. At 12 feet from the SeaSonde antenna, power density levels are 0.08

milliwatts/cm2, or less than 30% of the maximum permitted exposure

17.

Given the conservative assumptions made in these “worst case” calculations, along with

the fact that ground reflections are not expected to occur, and that transmitted power levels are

typically much less than 50 watts, it is likely that the SeaSonde emissions are below the MPE

levels even near the antenna. However, we can confidently state that SeaSonde emissions are

well below MPE limits at distances greater than 6 ft from the center of the antenna.

Summary

Each SCCOOS SeaSonde installation contributes to the increased knowledge and

understanding of the ocean and its ecosystems. It provides data that may be used for search and

rescue operations, and the increased safety of mariners. The EMF emissions from these

installations are well below levels considered safe by various standards-setting agencies

including the FCC and OSHA. SeaSondes at comparable distances from other occupied

structures have been operated at other sites for several years with no adverse effects. No ill

effects on human health are expected from the operation of these installations. Public safety is a

primary concern; improved public safety is one of our research goals.

21 September 2007 To Whom It May Concern:

The purpose of this letter is to request permission to install an oceanographic instrument at the Navy Site on Santa Cruz Island, California. This installation would allow us to map ocean currents in areas of the ocean that are inaccessible from other locations. The following paragraphs summarize the purpose of the installation, its practical benefits, and the installation requirements.

An instrument at Santa Cruz Island would become part of the Coastal Ocean Current Monitoring Program (COCMP). As funded by the California State Coastal Conservancy, the goal of the COCMP is to obtain real-time measurements of ocean currents, and then to make these measurements useful to those tasked with addressing coastal water quality, coastal hazard, and marine life resource issues. The instrument we propose to install would measure the ocean current speed and direction up to 60 miles offshore. Researchers would use this data to understand the ocean circulation and its effect on local ecosystems, fisheries, coastal erosion, and storm water transport and dispersion. This data would also aid maritime vessel traffic, oil spill response, and search and rescue operations. When completed, the COCMP will measure currents along the entire California coast, giving scientists, researchers, and resource managers an unprecedented understanding of the state and health of the coastal ocean.

The attached figure 1 shows an example of currents from the Santa Barbara Channel.

These ocean current maps are posted hourly, in real-time, on Southern California Coastal Ocean Observing System (SCCOOS) (http://www.sccoos.org/data/hfrnet/) and University of California, Santa Barbara (http://www.oceancurrentmaps.net/) web sites. An installation at Santa Cruz Island would work with existing instruments in the Santa Barbara Channel, and with instruments to be installed at Point Mugu and San Nicolas Island. Together, these instruments would measure ocean currents in the Santa Monica Bay, and west across the Santa Cruz basin between Santa Cruz Island and San Nicolas Island. Current speed and direction is measured hourly for every 2 square kilometers of ocean surface.

The ocean current measuring technique is a type of low powered radio system (50 W

maximum) that operates in the HF band (~13.5 Mhz), similar to a VHF or CB radio. The computer and electronics are typically housed in a small shed or a smaller weather-proof metal box, and cables run to two antennas, one for transmit and one for receive. We’ve experimented with transmit antennas and based on our experience we would need an approximately 45 ft. tall transmit antenna for Santa Cruz Island. Currently we are adapting a flag pole for the purpose, which would require not guy wires or bulky support structure. The receive antenna consists of 4 horizontal whips and one vertical whip, each 8 ft. long, on top of a 15 ft. mast (see figure 2 below). The system requires ~350 W of electricity to operate.

Installing this instrument at Santa Cruz Island would greatly benefit our project and vastly improve our knowledge of currents in the Southern California Bight. Please let me know if I can provide any further information. Thank you for your consideration,

COASTAL OCEAN CURRENTS MONITORING PROGRAM SURFACE CURRENT MAPPING SYSTEM

SURFACE CURRENT MAPPING ANTENNA SITE PROPOSAL

I. PROJECT REQUEST

I am writing on behalf of a consortium of research organizations participating in the Coastal Ocean Currents Monitoring Program (COCMP), funded by the California State Coastal Conservancy. Participating consortium members are part of the Central and Northern California Ocean Observing System (CeNCOOS) or the Southern California Coastal Ocean Observing System (SCCOOS). In conjunction with SCCOOS, Scripps Institution of Oceanography (SIO) would like to deploy a surface current mapping antenna at the Ocean Institute in support of the ocean monitoring program. In this location, we would locate an antenna, electronic enclosure with access to power and a network connection for data transmission.

II. PROJECT DESCRIPTION The goal of the coastal ocean observing system is to obtain real-time measurements of ocean currents, ocean wave heights, water temperatures, meteorological parameters, and other oceanographic parameters. The measurement of coastal currents allows scientists to examine how the ocean interacts with the atmosphere and land, and responds to long and short time scale climate change. Understanding ocean circulation benefits numerous research efforts, environmental applications, government projects, and public interests. A few applications include water quality monitoring (aid in identifying the source of pollution impacting beaches and coastal waters), oil spill response (forecasts used for predicting spill dispersion), search and rescue (real-time currents can help narrow search paths), and recreation (wave, wind and current information to help plan and minimize exposure to severe conditions at sea). Central to this research is the measurement of coastal currents along a wide region of the coast, the backbone of which is the installation of approximately thirty five short-range transmit and receive radio antenna systems, and fifteen long-range systems which are used to map ocean surface currents. The Surface Current Mapping technique is a type of low powered radio system that operates in the HF band. High-resolution systems operate in the region of 24 - 27MHz and produce current measurements with 1-2km resolution and approximately 30km coverage; standard SeaSondes operate within 12 - 14MHz with 1-5km resolution and 70km coverage; long-range SeaSondes operate within 4-5MHz and produce measurements at 6-10km resolution over 100km range. Radio waves, tuned to a specific length of ocean waves, originate from the transmit antenna onshore, scatter off the ocean's surface, and are subsequently acquired by the

1

receive antenna. The received radio signal, when appropriately processed, allows for the measurement of currents at different ranges and angles using a radial pattern centered at the receive antenna. By combining data from multiple systems deployed along the coast, both northerly and easterly currents can be determined. All data will be made available to the public in real-time.

III. DEPLOYMENT SPECIFICATIONS

a. Ideal deployment conditions include the following: 1.) Close to ocean: less than 150 meters to water's edge 2.) Wide field of view (180o up to 360 o) 3.) Area relatively clear of obstructions (power lines, antennas, large metal

objects) 4.) Flat or sloping hill to rear (steep hills will cause reflections) 5.) 120 AC power available (~800Watts continuous). If necessary, systems

are installed with solar power. 6.) Network connection accessible (either through existing network or

COCMP installed wireless connection)

b. Radio antenna specifications:

1.) High-resolution SeaSonde (qty. 1 antenna) • Transmit/receive antenna is 20 feet high • Four 4 foot radial elements are located at 12 feet • One 8 foot vertical element is located at 12 feet • Antenna mast supported via guy wires

c. Enclosure houses transmit and receive electronics, universal power supply, and air conditioner for climate control. This equipment is easily contained in an enclosure 34"D x 24"W x 36"H or can be housed in existing infrastructure. Power requirements for the system are 120VAC at approximately 1,000Watts continuous.

d. Below are pictures of a high-resolution deployment, long-range deployment, and

enclosure and mounting images.

of Oceanography, UCSD is being funded by NOAA to initiate shelf to shoreline

observatory developments creating an ocean observation system within the Southern

California Bight. One component of the multidisciplinary coastal observatory includes

near real-time measurements of surface currents. The measurement principle for surface

current mapping systems is based upon transmitting radio waves tuned to a specific

length of ocean wave, and acquiring the reflected signal from a receive antenna. The

signal, when appropriately processed, will return radial current vectors covering a range

of up to ~150km for long-range system in ~5km intervals. Combining data from multiple

systems deployed along the coast enables us to calculate both northerly and easterly

currents. The system deployed on San Clemente Island would optimally combine with a

long-range system deployed on Point Loma. We are actively pursuing site requests at the

USCG facility on Point Loma. We currently have a high-resolution system (~40km

range; ~1.5km resolution) deployed on SPAWAR property at Battery Humphries, which

combines radially with installations at Border Field State Park and Coronado Island.

Surface current measurements can be viewed at:

http://www.sdcoos.ucsd.edu/data/CurrentsList.cfm.

After reviewing potential sites on San Clemente Island, we have determined two potential

locations for one of the long range antenna systems (noted above). Long-range surface

current mapping systems consist primarily of two antennas (transmit and receive), a

weatherproof housing for electronic equipment (transmit and receive module, data

acquisition computer, and networking equipment), and if needed a wireless network

antenna. I have included more detailed specifications including antenna and enclosure

dimensions as well as signal characteristics as an attachment. The installation would

include mounting the transmit and receive antennas 50 meters apart approximately 60

meters from the water's edge. If a nearby facility is available, we would use existing

infrastructure for housing the electronic equipment. Otherwise, we would install the

weatherproof housing, which has a typical footprint of 126cm (h) x 63cm (w) x 85cm (d).

We would also ensure networking connectivity to SIO, and if required, install a wireless

network antenna linking to the San Diego Super Computer Center through the Mount

Thirst connection. Following initial installation, maintenance visits to the island would

consist of approximately four trips per year for system check and data backup.

(Be Specific) URGENCY OF APPROVAL AND WHY ??:_We hope to install the system as

soon as possible in order to start testing and mapping the surface currents in Southern

California. The project goal is to have the system operational by the end of the summer.

LCDR Jeff Brockus, PE Chief, Shore Team North Maintenance & Logistics Command Pacific (stn) November 10, 2005 Subj: USCG assistance request for surface current mapping project In conjunction with the Southern California Coastal Ocean Observing System, Scripps Institution of Oceanography, I would like to request a surface current mapping antenna installation on US Coast Guard property at Point Loma. We are also in the application process for a similar installation on Navy property on San Clemente Island as a complimentary site. The goal of the coastal ocean observing system is to obtain real-time measurements of ocean currents, ocean wave heights, water temperatures, meteorological parameters, and other oceanographic parameters. The measurement of coastal currents allows scientists to examine how the ocean interacts with the atmosphere and land, and responds to long and short time scale climate change. Understanding ocean circulation is also important to scientists conducting research related to the transport of fish larvae and marine pollutants. Another goal of the project involves the development of ocean computer models of physical and biological processes, which integrate the experimental mapped ocean surface currents. The ocean current measurements are numerically assimilated to initialize, constrain, and validate the models. Assimilation of HF radar measurements into advanced computational oceanic models is a challenging and experimental research area, that when matured, could prove extremely beneficial in many areas including search and rescue, oil spill response, coastal erosion, maritime vessel traffic, and storm water transport and dispersion. As indicated, central to this research is the measurement of coastal currents along a wide region of the coast, the backbone of which is the installation of approximately twenty short-range transmit and receive radio antenna systems, and four long-range systems which are used to map ocean surface currents. The Surface Current Mapping technique is also referred to as CODAR (Coastal Ocean Dynamics Applications Radar) and is a type of low powered radio system that operates in the HF band. These HF radar systems are also presently being evaluated by other agencies for their ability to remotely track surface vessels. Should this capability reach a mature level, the combined capacity of mapping ocean currents (primary) and tracking vessels (secondary) could be of potential interest to the USCG mission.

After a preliminary review of sites, we have determined that Point Loma is an ideal location for a long-range system. I have included an informational package, which provides an overview of system specifications, installation components, and an installation scenario. Please let me know if I can provide any further information. We look forward to working with you.

SCRIPPS INSTITUTION OF OCEANOGRAPHY Marine Physical Laboratory Carl Huie Federal Communications Commission May 23, 2005 Subj: experimental license expansion justification A consortium of research scientists from the University of California (UC), the California State University system (CSU), and private learning organizations (University of Southern California, Naval Postgraduate School) have been funded by both Federal and State of California agencies to conduct scientific research along the coast of California. Central to this research is the measurement of coastal currents along a wide region of the coast for purposes of examining how the ocean interacts with the atmosphere and land, and its response to short and long time scale climate change. Examples include ocean response to winter storms, El Nino, the Pacific Decadal Oscillation, and other climate change events. Understanding ocean circulation is also important to scientists conducting research related to the transport of fish larvae and marine pollutants. Agency sponsorship for these scientific efforts includes research offices from within NOAA, the National Science Foundation, the Office of Naval Research, and the California State Coastal Conservancy. The wide area observation region for these projects has stimulated the creation of a scientific ocean observatory composed of many different types of scientific instruments (both in the water and land based), whose data when collected and integrated, are analogous to a multi-user telescope. A component of this observatory involves the installation of several low power radio antennas, which use backscatter to map ocean surface currents. This scientific instrument (also referred to as CODAR for Coastal Ocean Dynamics Applications Radar) operates in the HF band. The research tool is experimental and is currently being evaluated at many sites around the country for their ability to accurately measure ocean surface currents. Several studies are underway to compare CODAR generated ocean surface currents with buoys and underwater robots. These efforts will continue with the wide area expansion proposed. Another goal of the project involves the development of ocean computer models of physical and biological processes, which integrate the experimental mapped ocean surface currents. The ocean current measurements are numerically assimilated to initialize, constrain, and validate the models. Assimilation of HF radar measurements into advanced computational oceanic models is a challenging and experimental research area, that when matured, could prove extremely beneficial in many areas including search and rescue, oil spill response, coastal erosion, maritime vessel traffic, and storm water transport and dispersion. Frequency band usage at the existing antenna sites for mapping surface currents has traditionally fallen under a not to interfere FCC experimental frequency license. We desire an extension of this allocation in support of these research efforts to our expanded coverage area. Please feel free to contact us should you desire additional background on our scientific research or radio spectrum needs.

Annual Work ProgramSouthern California Coastal Ocean Observing System (SCCOOS)

Grant # 04-078

Period of Performance: Year 4, 1 January 2008-31 December 2008 (Project No-Cost Extension)

Project Description

This grant by the California State Coastal Conservancy (SCC) covers the implementation for the CoastalOcean Currents Monitoring Program (COCMP) in Southern California. Originally a 3 three year grant, ano-cost extension was granted to allow work to continue into the 4th year to complete the project. Thegrant is to develop and provide ocean current monitoring infrastructure for the region on a variety of spaceand time scales, in a manner that is best suited for a broad range of regional and statewide needs. Data andinformation products will be made available in near real-time where possible, and integrated with monitor-ing data obtained by regional data provider user groups when those data are made available. The 2008Annual Work Program includes an internal program management structure that will allow efficient design,installation, and operation of the California Proposition 40/50 funded infrastructure. The SouthernCalifornia Coastal Ocean Observing System (SCCOOS) is coordinating with colleagues in NorthernCalifornia to ensure a unified statewide system, as specified through a Memorandum of Understanding(MOU). (http://www.sccoos.ucsd.edu/docs/SCCOOSMOU04.pdf).

The system elements proposed to meet COCMP objectives include Surface Current Mapping (SCM) tomap ocean surface currents within the Southern California Bight; high resolution (GPS-tracked) drifters;propeller and buoyancy driven autonomous platforms, integration of data from moorings maintained bylocal agencies; surf zone current measurements and modeling; a Regional Ocean Modeling System with dataassimilation for nowcasting and forecasting of the physical properties of the ocean; and IT infrastructureconsistent with the architecture proposed for the U.S. Integrated Ocean Observing System (IOOS). To com-plement the establishment of Southern-California wide observing system infrastructure, a focused, integra-tive effort of many of the COCMP components was executed in fall of 2006 in the San Pedro/HuntingtonBeach region as an end-to-end effort to connect nearshore observations to end-user water quality needs(HB06). Alliances with additional data provider user groups will be established to entrain the widest rangeof interested parties. The following is the 2008 Annual Work Program to complete the identified goals andobjectives of the program in its 4th year.

Tasks and Deliverables

The Coastal Ocean Currents Monitoring Program will continue with the activities proposed in theoriginal SCCOOS grant agreement. Estimated time periods are provided in bold and parenthesis to repre-sent the minimum requisite time period to complete each task, and do not represent man months of effortexpended. These periods do not necessarily commence upon initiation of this grant or approval of theAnnual Work Program, but are program specific and often inter-related to the progress of other relatedtasks. Therefore, durations are initiated, managed and may be modified at the discretion of the program sci-entists. Activities should be considered ongoing throughout the reporting period unless otherwise noted.


A. ESTABLISH SCM ARRAY FOR MAPPING OCEAN CURRENTS• Finalize the installation of new sites to achieve full build out of SCCOOS COCMP. Our projected

install rate is eight sites this year. Locations will be determined in conjunction with Task A.1, andprioritized based on site accessibility and permitting response. Proposed and active HF radar sites canbe viewed from http://www.sccoos.org/SoCal.

• Install communication hardware where necessary as sites become available, in order to operate andconfigure remote sites.

• Continued support and improvement of data access to hourly radial and combined ocean surface cur-rent measurements for near real-time monitoring. Provide data in standardized format that provideutility to COCMP user-base.

Deliverables for December 2008:

• Status report on HF radar systems and product development. Updated map of SCMantenna locations along the coast, continued documentation submitted for proposed siterequests permits.

While individual PI analyses of the data maycontinue in 2008, this task is essentially complete. .

Deliverable for December 2008: Summary of any new results from analysis conducted in2008.

Task B.2 Transition Zone Observations - AUV Deployment

• No funding exists for this component in 2008.

Task B.2 Transition Zone Observations - Drifter Deployment


Task B.2 Transition Zone Observations - Mooring Deployment


Task B.3 Modeling wave evolution & currents to nowcast surf zone currents (Santa Monica and

Huntington Beach region)

• Preliminary results from HB06 show that our operational models for waves (seaward of the surf zone)and alongshore currents (within the surf zone) are usually reasonably accurate. However, the wavescomponent of the model does not include seas generated by locally strong winds, and in these casesthe associated model for wave-driven alongshore currents also necessarily fails. To the extent possiblewith the available funds, we will include local winds in the wave and current models for the SantaMonica and Huntington Beach regions.

• Real-time estimates of surf zone waves and current for a 4.5-km reach at Huntington Beach, alreadyavailable at http://cdip.ucsd.edu/hb06/ using interim models, will be upgraded to use improved mod-els (Task B.1). Additionally, the model coverage will be expanded to include the Santa Monica andHuntington Beach regions.

Deliverable for December 2008: Continuation of tasks identified for 2007 including con-tinued operation of real-time models for waves and surf zone currents in the Santa Monica andHuntington Beach regions where possible.

Task B.4 Northern and Central Nearshore Wave Data

• Continued operation where possible of the nearshore wave predictions expanded in 2007 thatinclude other sections of the Central and Northern California coastline that are impacted by highsurf. These data will be available on the WWW, and provided to Naval Postgraduate School inves-tigators for use in their longshore current model.

Deliverables for December 2008: Continued Operational, real-time wave modeling ofselected high impact sections of the Central and Northern California coast where possible.

C. ESTABLISH SUBSURFACE OBSERVATIONS

Task C.1 - Underway CTD

• Evaluate the newly-commercialized underway CTD operational deployments.

• Continue operations of the underway CTD system across the San Pedro Channel in the LA region.

• Conduct Quality Assurance/Quality Control (QA/QC) of data.

Deliverable for December 2008: Continued operation of the underway CTD and submis-sion status report of underway CTD; respective data retrieval and QA/QC.

Task C.2 - Bight-Scale Monitoring–Glider Operations

• Continue (under COCMP funding) to maintain hopefully continuous operation on CalCOFI Line 90(Dana Pt.) sampling temperature, salinity, currents, and phyto- and zooplankton abundances.

• Continue (under other funding) similar coverage on Line 80.

• Continue (under COCMP funding and in collaboration with Francisco Chavez of MBARI) to use asingle glider to occupy a repeated line off Monterey Bay near CalCOFI Line 67. This will extend cov-erage to describe, on seasonal time scales, the changes in physics, phytoplankton and zooplankton tothe area between Monterey and San Diego.

• Continue quality control of the data, begin providing the data in real-time to the ROMS modelingeffort, and begin retrospective analyses of both HB06 and the repeated offshore lines.

Deliverable for December 2008: Submit a status report on the missions enumerated above.Maintain the publicly accessible data archive.

Task D.3 Covariance and Objective Mapping using COCMP observations

• Refine and deploy new mapping technology based on radial data instead of vector currents. Thisshould improve quality control and mapped currents. Transition this new method to the real-timeapplications.

• Similarly convert the covariance estimation from using vector currents to radials. Work on methodsto keep covariances well-behaved (positive definite). Continue to decompose covariance by differentphysical processes, including frequency bands and forcing sources (tides, winds, remote forcing). UseSan Diego data for test case scenarios.

• Continue Regional Ocean Modeling System (ROMS) runs on fine grids using observed winds and
