Gray Whales 101
Collision/Entanglement Risk: 20,000 whales x 2 trips per year x 20,000 lb/whale = A lot of blubber!

Purpose, Objectives, & Integration
Alignment to Program’s Mission and Objectives Acceleration of clean, affordable energy generation that is both
economically viable and environmental responsible. Provides mitigation technology for potential show stopper.

Technical Approach
Project Objective and Technical Approach Project Objective: Test the effectiveness of an acoustic deterrent
mechanism in deflecting migratory gray whales around wave energy structures.
Technical Approach: Intermittently operate acoustic deterrence device at Yaquina head and measure behavioral response changes using the same theodolite tracking methodology used for the 2008 baseline study.
Key Issues To Be Addressed and Their Significance Effectiveness of Deterrence: The test will verify the effectiveness of an
acoustic signal to ‘nudge’ whales from a project area.Significance – validates mitigation approach IF mitigation is required
Unique Aspects of Approach Collaborative effort between OSU/MMI and PEV Leverages more than $300K in previous OWET funding
6 | Wind and Water Power Program eere.energy.gov
Technical Approach
Deterrence device deployed in 45-m water depth – operates intermittently.
Research team positioned at base of Yaquina Head Light.
Spotter initiates contact with binoculars and relays approximate position to Theodolite operator
Theodolite measures inclination and distance to target.
Computer calculates position and predicts next surfacing.
Data analyzed to compare statistical presence at 500m and 2 km from sound source.

Technical Approach
Sound Projector located approximately mid-water
400kg Mellinger Lander Anchor
Batteries and electronics located on anchor
Rechargeable battery Sound Level 170dB at
source 1 sec pulse per minute for
6 hours per day Surface marker with
Carmanah light per USCG PATON regs

Plan, Schedule, & Budget
Schedule Initiation date: September 1, 2009 Missed 2009/2010 migration due to contract and NOAA permit delays. Missed 2010/2011 migration due to equipment failure. Ready to go for 2011/2012 migration! Planned completion date: October 2012
Major Milestones Task 1 Permits – All Permits Received - November 2010 Task 2 Research – Acoustic Device (rev 2) Complete – October 2011 Task 2 Research – Data collection – late Dec 2011 or early Jan 2012
Budget No variances at this time. OSU able to absorb equipment replacement cost Estimated Expended Budget to Date: $333,537

Accomplishments and Results
Task 1 – Permits Received Oregon Department of State Land’s Short Term Access
Agreement on 9/30/2010. Received Army Corps of Engineers permit on 10/26/2010. Received NOAA Level B harassment permit on 11/1/2010. Received Oregon State University’s Animal Care and Use Permit on
11/17/2010. Received Letter of authorization from the United States Coast Guard in lieu
of the Private Aid to Navigation on 11/18/2010 after providing more detail on the specific navigation light that was selected.
Copies of Permits have been posted to the MHK KnowledgeBase at:

Challenge/Resolution
Electronics Enclosure Challenge – Reliability of electronics enclosure (failed on first
deployment) Resolution – Redesign enclosure and pressure testing prior to
deployment.
Weather Challenge – Initial deployment and observation limited
Resolution – Hope for sunny skis and fair seas!
