Cruise Objective:   "An Observational/Modelling Study of Wintertime
                    Convection and Water Mass Formation (CONVEX)" - NSF
                    grant OCE-9530249.
                    Primary mission: Place a suite of instrument moorings
                    in the central Wilkinson Basin (42-42' N, 69-38' W).
                    Secondary mission: before and after the mooring
                    deployments (as time permits), conduct a hydrographic
                    survey of the basin area.
Science Activities: Sub-surface mooring recovery/redeployment, CTD/rosette
                    casts (optimistically 20-25 stations)

                    Initially, we will acoustically release and recover the
                    bottom of a mooring placed at this site in October '97
                    and set adrift early December (due we suspect to
                    fishing activity - we have recovered the buoy and
                    tackle to about 215 m depth. Flotation, rubber bands
                    and an acoustic release are still attached to the
                    anchor). Three moorings will then be placed to augment
                    a guard buoy and thermister chain deployed at this site
                    in October 1997. These include (1) a 5 ft dia steel
                    guard buoy, (2) a 6 ft dia foam instrument buoy with an
                    IMET weather package on the tower, a string of 4
                    temp-cond pairs on a cunducting cable, and 2 workhorse
                    ADCP units mid-depth, and (3) a subsurface Aandaraa
                    thermister chain. This set of deployments will be
                    confined to a tight triangle 100-150 m on a side.
Operations Area:    Wilkinson Basin / Gulf of Maine
                    42-43N, 69-71W
                    Water depth: 60-280 m

Notes:                            * Point of Contact & ChSci is Frank Bub
                                  * Requirement for continuous depth
                                  recorder use
                                  * We hope to download all ship recorded
                                  data (CTD/met/tsal/navigation/adcp)
                                  before docking

                                  1@215m)
