+--------------------------------------------------------------------------+ | OCEANUS CRUISE SYNOPSIS | +--------------------------------------------------------------------------+ Voyage - Leg: OC 433 Voyage Dates: 31 Oct - 12 Nov, 2006 Chief Sci(s): Bruce Keafer (McGillicuddy) Address: WHOI Redfield 3-32 Phone: 508-289-2509 Email: bkeafer@whoi.edu Cruise Objective: 1)NOAA event response and modeling project- Re-map the distribution of toxic dinoflagellate cysts of Alexandrium fundyense and Alexandrium ostenfeldii in the Gulf of Maine and the Bay of Fundy. This survey is part of the emergency event response and modeling studies associated with blooms of 2005 and 2006. This survey will show the change in cyst abundance and distribution after the bloom of 2006. The results will be input into biological/physical models as the inoculum for simulations of the next bloom in the spring of 2007. 2)Piggyback objective-pCO2 survey perfomed by the University of New Hampshire - Underway data collection system connected into the ship's uncomtaminated seawater flow. CTD/Optical profiler deployed about once/day or as time permits to provide vertical resolution of hydrographic properties. Science Activities: Craib Coring, Van Veen grab samples, Optical profiler Operations Area: Gulf of Maine/Bay of Fundy 42-45N; 66-71W 20-270 SSSG Tech: sssg @oceanus.whoi.edu Departure Port: Woods Hole, MA Agent: Master R/V Oceanus Attn: Scientist's Name c/o WHOI 266 Woods Hole Rd.

WHOI-Provided Science Berthing Van Tools: Program-Provided Craib Corer - 280 lbs. Science Tools: Shipboard Equipment/Nav: Other Requirements: Night Work Anticipated There will be two types of deployments over the starboard side: 1) Craib Corer or Van Veen grab sampler. This will require the termination of the standard conducting wire of the primary winch system to be cut and a Chinese finger installed for physical connection to the Craib Corer (this configuration was used during a 2005 survey on Oceanus and worked well). Weights will be added to the Corer as needed (probably 6 x 25 lbs= 200 lbs + 80 lbs Corer = 280 lbs total). If possible, a wire pinger will be installed directly on the Craib Corer to determine its location off the bottom before entry into the sediment. - An optical profiler package has been reinstated (JD 10/25) 2)An optical profiler package with Sea-bird CTD will be deployed separately off the starboard side using the ship's alternate winch system (about once/day). The data is recorded internally and thus will not need a conducting wire connection, only a physical connection. The CTD termination will not need to be cut (we hope). Weight will be added as needed.. Notes: Spill kits with adsorbents for formalin will be brought onboard. Waste formalin (5%) will be collected in a glass vacuum container and transfered to a plastic 5 gal. drum for storage on the O1 deck tied into a cage. That drum will be removed by the Safety Office upon disembarkment. Unused formalin and methanol along with the samples will be returned to the lab. We will bring Craib Corer with yoke to attach to Chinese fingers at termination of CTD cable. We need WHOI to supply 2 Van Veen samplers as back-up sampling equipment should the Craib Corer fail or misfire in hard sediments. Since CTD/rosette is not requested, though CTD Rosette will be aboard. there may be a need by UNH personnel to collect water samples at various times. This will be done with Niskin bottles that they provide to grab ground-truth samples for their PCO2 survey. Navy Clearance Status: Last Modified: 12/13/2006 Check List: Required?
