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

                       On Deck Incubators will need 3lbs of ice per hour
                       for a 24 hour period. Multiple periods per cruise
                       with down time in between

                       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)
