TerraScan Seanet WHOI-Provided Science Berthing Van Tools: VPR - Winch (440VAC, 30 Amps) Mocness ARGOS RDF Program-Provided SPMR system (Bio-optical sensor) Science Tools: Possibility of 3rd chest freezer (sci) in UNOLS GP Van Chiller for Incubator on aft deck will be tucked onto 01 Deck as last year - (220 VAC, low amps ~8 amps) Russian made microscope in main lab (220VAC, low amps) Shipboard Equipment/Nav: Other Requirements: Night Work Anticipated Notes: All hazardous materials will be removed by the science party at the end of the cruise in Woods Hole There will be 2 ship survey work with the Weatherbird 2 Drifting Spar Deployment - Deployed during Survey 1, recovered during Survey 2 or Tracer 2. Procedure procured and given to Bosun. The SPMR is a hand-lowered instrument that is designed to minimize ship shadows. There will be a small hand reel for the cable that needs to be bolted to the deck. We want casts from daylight hours (preferably 0900 to 1600) and normally deploy from the stern with stern facing the sun. The deployment takes two people minimally; one running the aquisition computer and one handling the kevlar cable. Transit 3.5 days outbound (includes test stations in slope water, Gulf Stream, and Sargasso) 1.5 days inbound Search: 5 days VPR + XBT underway survey CTD casts and MOCNESS tows: (1) eddy cores, (2) eddy edges, (3) "ambient" First snapshot: 6 days CTD grid with noon and midnight MOCNESS tows - 4 days 25 stations at 1 hour per station 1/2 hour bio-optical casts for stations falling between 0900-1600 hrs 8 MOCNESS tows at 3 hours per tow 2 days steaming time VPR survey - 2 days Second snapshot: repeat of first snapshot, 6 days Joint operation with Weatherbird (intercalibration stations) Ledwell (UNOLS GP) van on starboard, Main Deck Lott van on 01 Deck, aft Navy Clearance Status: Last Modified: 12/13/2006 Check List: Required?
