on-deck incubators (deck locations TBD) – they will be occupied for the whole cruise. Nicole Pereira will be running 2 x 30 hour incubations in the small Zehr Lab incubators with 60L water each from two 1700hrs casts (deck locations TBD). Sara Thomas will require 1 of the UH on deck incubators and she is planning to bring a chest freezer sized incubator that would need to go into the staging bay on the KM (she will have an incubation continuing from the previous HOT cruise in this incubator). 4.0 OPERATIONAL PLANS Shipboard operations: CTD operations; primary productivity array; optics casts; trace metal sampling; misc. experiments. Underway/continuous operations: ADCP, thermosalinograph, pCO2 system, fluorometry, and meteorology. Whenever pumping of the ship’s tanks is needed, it must be conducted outside the circle that defines station ALOHA (Sect. 1.0). To avoid disruptions in the schedule, this operation should be coordinated with the chief scientists and we have allocated three times a day when this operation can occur. 4.1. Water column measurements Vertical profiles of temperature, conductivity and dissolved oxygen will be made with an instrument package consisting of a Sea-Bird CTD attached to a 24-place rosette with 12 liter Bullister sampling bottles. We will need the ship’s CTD winch and crane for these operations. Water samples for biogeochemical measurements will be collected on each cast. There will be an additional instrument to be included with the OTG CTD package – an ISUS which is a real time, chemical free sensor for measuring nitrate. Its power requirement is 0.625 amps at 12V. Furthermore we wish to mount a lowered ADCP to the rosette frame. The lowered ADCP is self-contained and does not need integration with the CTD. It has a mounting that puts it at the centre of the CTD frame. 4.2. Pump sampling In addition to sampling the water-column using the CTD-rosette, we will also use Dan’s diaphragm water pumping systems. It will be installed and deployed at 25m. Flow rate is roughly 4L/min. 4.3. Automated Trace Element Sampler (ATE) The ATE will be hand-deployed daily off the back deck to a depth of 10 m. The ATE will be recovered after 30 minutes in the water. The ATE is approximately 1’ tall and 4’’ in diameter, weighting 5 lbs. 4.4. VANE sampling Trace-metal clean samples will be collected once using VANE samplers attached to the 0.322 hydrowire. Depths are base of ML, DCM, 50-70m below DCM, 250, 375, 500, 750, 1000, 1200 (hydrothermal maximum), and 1400 [max depth of cast is 1500m].

4.5. Hyperpro Daily deployment of Satlantic radiometer to characterize irradiance and radiance. The Hyperpro is a profiling unit with one up-looking and one down-looking hyperspectral radiometer, a WET Labs ECO-BB2F triplet (measuring Chlorophyll-a fluorescence and backscattering in the blue and red wavelengths), temperature and conductivity sensors. This instrument also incorporates a ship mounted surface radiometer. The Hyperpro will be deployed from the stern through a small block hung from the A-frame. The instrument is hand-lowered and retrieved with assistance from the winch. 4.6. ACS/AC9/FRRf/LISST An optical package including a Wet Labs AC9 that measures water column spectral absorption and attenuation at nine wavelengths, a Chelsea Fast Repetition Rate Fluorometer (FRRf), a SeaBird Seacat with temperature, conductivity, fluorometer, and pressure sensors, and a LISST particle size and distribution analyzer will be deployed two times during the cruise. Each deployment will consist of two up and two down profiles to a target depth of 200 m at a constant speed of 10 m/min during both the downcast and upcast. An instrument soaking period at just below the surface will be required between the two profiles. The A-frame and capstan will be needed for this operation. 4.7. Primary production experiment Samples for the primary productivity experiment will be collected from the rosette. Before dawn (Sunrise 0606 hrs on August 8th), a free drifting incubation array will be deployed from the stern using the A-frame and Sea-Mac winch. The array is equipped with two ARGOS satellite transmitters (platform #’s 3028, 60482, emailing positions to [email protected], password: argosfix), strobe lights and a radio transmitter (156.425 MHz). The ship shall keep within site of the array while performing CTD operations for the last 6 hours of the approximately 12-hour time the array will be in the water unless the array drifts outside of the ALOHA circle. If the array drifts out of the circle, the ship should return inside the circle to conduct CTD casts, and the monitoring of the array will be coordinated with the watch leader. All radioactive waste generated by the experiment shall be returned to the University of Hawaii. Only qualified personnel shall handle radioactive material. 4.8. Acoustic Doppler Current Profiler The ship’s acoustic Doppler current profiler (ADCP) will be in operation during the duration of the cruise. The OTG technicians will be in charge of the ADCP system. 4.9. Thermosalinograph, pCO2 system, Fluorometer, and meteorological system The ship’s thermosalinograph, pCO2 system and fluorometer sampling the uncontaminated seawater supply system will be in operation during the duration of the cruise while the ship is outside of Snug Harbor. The ship’s meteorological system shall be in operation throughout the cruise. Access to real-time underway data through the ship’s network will be required. The OTG technicians will be in charge of the thermosalinograph, pCO2 system, Fluorometer, and meteorological suite operations.

5

4.10. We also request that OTG group initiate the shell script to automatically send the ships coordinates approximately hourly by email to [email protected] and [email protected]. This will be important to cross-calibrate the instrumentation in the water (sea-gliders-floats). If possible, it can be left running from July-September as it would be useful on the HOT legs as well. 5.0. EQUIPMENT 5.1 The science party shall be bringing the following

1. One 20 ft. laboratory van (Karl Flow Cytometry) 2. One 20 ft. laboratory van (#23) with assorted equipment for radioisotope and

general use 3. One 20 ft. OTG rad van 4. All required chemicals and isotopes 5. Large vacuum waste containers 6. Liquid nitrogen dewar 7. Polypropylene line 8. Drifting primary production array with light and radio transmitter, floats, weights,
