Chief Sci(s): Barbara Hickey (Hickey) Address: School of Oceanography Box 357940 Universtiy of Washington Seattle, WA 98195-7940 The contact person for questions regarding this cruise is Nicolaus Adams at National Marine Fisheries Nicolaus.Adams@noaa.gov (206) 860-6787 Phone: Hickey 206-543-4737 Email: hickey@ocean.washington.edu Cruise Objective: This cruise gives scientists an opportunity to measure the physical, chemical and physiological conditions under which the algae Pseudo-nitzschia produce the toxin domoic acid, where and when they release it into the environment, and the conditions under which the toxin-producing algae move toward the coast of Washington. When this happens it is taken up by shellfish, which leads to closure of beaches to razor clam collection to avoid outbreaks of toxic shellfish poisoning. Science Activities: CTD surveys, surveys of surface water properties including dissolved Fe using a towed fish and the shipboard underway system and ADCP, identification of species, on-deck incubation experiments, and shipboard laboratory experiments will be performed. Drifters will be released both near the Juan de Fuca Eddy, and near the coast. The ship will follow these drifters for several days each, so scientists can re-sample parcels of water as they age to measure changes in physical, chemical and biologic constituents. Additional biological samples will be taken for growth rate determinations and incubation experiments. Many of the biological samples taken will be preserved for further analysis on land.

Freezer Walk In Cooler IMET Sensors - Wind (speed and direction), air temperature, PAR WHOI-Provided Science Seabeam Tools: Isotope Van - Liquid Scintillation Counter Chemical Storage Van Anti Vibration Table (Dark Room) We request a fluorometer be installed in the flow-through system. For the growth experiments, we are requesting that a PAR sensor be mounted on the ship, as well as on the CTD. WHOI will provide an over the side pump system and Thermosalinograph samling to minimize noise from bow thrusters. Program-Provided Special Handing Needs: Science Tools: We plan to tow a fish for sampling dissolved heavy metals (Fe and Cu0, by suspending a fish from the ship's starboard aft telescoping boom crane. Kevlar line and plastic tubing run from the fish, through the block on the crane, to a spool on deck, which is wound by hand. The tubing then runs through a pump near the ROV bay, then into the Wet Lab, where a clean (bubble) room (~8' x 5' in area) will be set up next to the aft port-side sink. The fish weighs ~15-20 lbs, and is designed to depress the line as the tubing is towed. In underway mode, the fish is surveying at ~5-10m depth. From time to time, profiles of Fe concentration will be taken at stations. To more easily track the drifters we would like to mount our GONIO antennae above the bridge. Van Veen Sediment Grab Smith-MacIntyre Sediment Grab Drifters Incubator in lab (size of a stand up fridge 110V) nitrate sensor on the CTD rosette, need to check on pressure tests of batter pack Shipboard CRUISE TRACK Equipment/Nav: This cruise plan will be highly adaptive, depending on where we find concentrations of Pseudo-nitzschia and/or domoic acid, and weather conditions. Initially, we will start the surface surveys in the Strait of Juan de Fuca, using both the flow-through system and the iron sampler attached to the ship's crane. These will be augmented with bucket samples taken to detect the presence of Pseudo-nitzschia (PN) and domoic acid. Thereafter, we will proceed to occupy a version of the hydrographic grid listed in and Figure 1. Upon completion of the hydrographic grid, we plan two personnel switches via a small-boat operation in Neah Bay, WA (just inside the Straits of Juan de Fuca) on September 13, and 20. This is a very protected harbor, and the water is almost always calm there. We will then return to the eddy, where we will deploy a satellite-tracked drifter, and sample water for more incubation experiments. We plan to follow this drifter for several days, making CTD casts and sampling water periodically, while shipboard experiments continue. We plan to go back to Neah Bay for a second personnel swap via small boat operation on September 20. We will then proceed to deploy and follow another drifter in upwelled water near the Washington (Perhaps between sites KB1-2). At least one repetition of the hydrographic survey is anticipated. Repetitions of the drift experiments are planned as time permits. The following figures show the station grid and cruise track form the ECOHAB cruise from September 2003. The grid remains the same, but the portion of the cruise where the ship follows drifters will, of course, be different. NOTE: CRUISE TRACK FIGURES WILL BE ELECTRONICALLY TRANSFERED TO THE MASTER SEPERATELY Other Requirements: Electrical Power Requirments: We will have 4 incubators aboard. Hopefully, we can put 2 on the main deck, and 2 on the 02 deck, forward of the vans. All need power and sea water hoses.We also plan to run a compressor for the iron pump on the main deck, port side. Notes: SAMPLING PLAN: Tentatively, a sub-surface mooring will be deployed in the southern portion of our sampling grid at 47DEG 36'N, 124DEG 31'W. This deployment would occur as the first event on this cruise. However, this operation may be cancelled as a result of ship schedule alteration. Continuous (Surface) sampling using the ADCP, the flow-through system with thermosalinograph and a Fluorometer installed, the iron-sampling boom, a Flow Cam, a Flow-Cytometer, and bucket samples (at times) The ADCP will be used continuously to measure profiles of the currents. The results will be analyzed and assimilated in the modeling effort. The thermosalinograph with fluorometer will measure surface temperature, salinity and fluorescence. The water pumped using the Fe-boom will continuously sample for iron, as well as collect clean water for many of the physiological experiments, and for surface nutrient analyses. The FlowCam will identify phytoplankton abundance, composition, size, fluorescence, light scattering, and species in the water. Flow-cytometry will also measure cell abundance, composition, size fluorescence and light scattering. Buckets will be used to collect samples to measure for PN cells and domoic acid as well as some species identification. Hydrographic surveys will measure temperature, salinity, fluorescence, oxygen, PAR and light transmission. Samples will be drawn from the Niskin bottles for nutrient analysis, as well as for size-fractionated chlorophyll, particulate and dissolved domoic acid, algal species identification (using a molecular probe), and micro-zooplankton grazing experiments. Periodically throughout the cruise CTD casts will be made to collect water for on-deck incubation experiments and the shipboard laboratory experiments. Water for these experiments will also come from the Fe-sampler. Several times during the cruise, the Fe-pump will be used to measure vertical profiles of Fe concentration. Occasionally, sediment grabs will be taken using a Smith-MacIntyre or Van Veen grab sampler. Drifters with an attached light will be released both near the Juan de Fuca Eddy and near the coast. The ship will follow these drifters for several days each, so scientists can re-sample the same parcels of water as they age to measure changes in physical, chemical and biological constituents and processes, as well as the physiology of the plankton. To more easily track the drifters we would like to mount our GONIO antennae above the bridge. Three other drifters will be released at times during the cruise to assess the surface current patterns. Laboratory experiments will include radioisotope uptake experiments using tritium, C-14 and Fe-59, as well as non-radioactive N-15. As discussed with David Simms, we will be deploying an Fe-fish over the starboard side using the knuckle crane. Fe- Fish will be towed during daytime ops between CTD stations at 7-8 Kts. To more easily track the drifters we would like to mount our GONIO antennae above the bridge. We will need power to incubators ( 2 on main deck, 2 on the 02 deck near the rad van, to the rad van and to the compressor used for pumping clean water from the Fe-fish. Hazardous Materials will be used in small amounts for many of the chemical and biological analyses that are planned for this cruise. A full inventory of chemicals used, their amounts, the procedures and spill kits needed to clean up spills,MSDS sheets (3 copies), personal protective equipment will be provided to the ship before the cruise and upon arrival in compliance with the directions on this website. A request for use of isotopes is in preparation, for submission to the WHOI RSO. All hazardous material will be removed from the ship after it docks at the University of Washington after the cruise. Arrangements are being made with the RSOs at University of Washington and the National Marine Fisheries NW Laboratory to receive shipments to the Atlantis, and to handle waste.
