+--------------------------------------------------------------------------+ | ATLANTIS CRUISE SYNOPSIS | +--------------------------------------------------------------------------+ Voyage - Leg: AT 11-17 Voyage Dates: 8 - 28 Sep 2004 Chief Sci(s): Barbara Hickey (Hickey) Address: Univ. of Washington Box 355351 School of Oceanography University of Washington Seattle, WA 98125 Phone: (360)825-3911 Email: bhickey@u.washington.edu/nkachel@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 released domoic acid moves 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. 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.

Direction, PAR, Ait Temp WHOI-Provided Science Isotope Van Tools: Program-Provided Science Tools: Shipboard Doppler/GPS Navigation Equipment/Nav: Other Requirements: Night Work Anticipated Notes: *** Please note the CTD stations water depths are 20 to 1000 meter requiring near bottom casts. Stations are located nearshore and in the traffic lanes. Operations are 24hrs a day. Arrangements are being made with the radiation officers at the University of Washington and the National Marine Fisheries Service in Seattle, WA to have any and all isotope material removed and/or disposed of at the end of the cruise on September 28. Other hazmat materials will be removed by the scientists responsible for each. Vera Trainer of NMFS is working with the WHOI RSO to obtain the necessary permits, and to fulfill WHOI's requirements for using isotopes aboard the Atlantis. Tow fish for sampling dissolved heavy metals (Fe and Cu0), by suspending a fish from the ship's crane on the starboard side of the main deck. Kevlar line and plastic tubing run from the fish, through the block on the crane, to a spool on deck, which is wound be hand. The tubing ten 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. For the growth experiments, we are requesting that a PAR sensor be mounted on the ship, as well as on the CTD. We request a fluorometer be installed in the flow-through system. Electrical Power Requirements: 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 CRUISE TRACK 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.
