    Science objectives/activities planned:
Primary mission: Place a suite of instrument moorings in the central Wilkinson Basin (42 deg 42' N 69 deg 38' W). Initially, we will acoustically release and recover the bottom of a mooring placed at this site in October 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. Secondary mission: Before and after the mooring deployments (as time permits), we will conduct a hydrographic survey of the ba
sin area. If weather is good and instrument recovery/deployment goes well, we estimate about 20-25 CTD casts. (note to WHOI readers - this single line type of entry in a tiny box is really difficult to enter and edit-- please excuse errors or inconsistencies - Frank Bub).

    Do you require slip rings?
YesNumber of conductors:your CTD
    Do you need non-standard wire?
NoIf so, what type?
    Do you need a traction winch?
Will you be bringing any equipment (winches, blocks, etc.) that lowers equipment over the side?

If yes, please provide details:
Will there be special requirements for:

    Electrical power
    Equipment handling
    Inter/intraship communications
    Science stowage

If yes to any of the above, please identify: We anticipate deployment of buoy jacketed steel cables (2@100 m, 1@ 215 m) from drums.

Will any of the following items be used on board?

    Explosive devices
    Portable air compressors
    Flammable gases
    Isotope van

Will hazardous material be used aboard, or deployed by an ROV? No

What measures or plans have been made a) in the event of a spill, and b) for the removal and/or disposal of these materials at the completion of the cruise?

Vehicle equipment required:Check one or both:
Major water samplers
Large capacity slurp samplers
Small capacity slurp samplers
Bio collection boxes
Push corers

    Other comments and information:
* Transducer requirement for continuous
depth recorder.
* We hope to download all ship recorded
data (CTD/met/tsal/navigation/adcp)
before docking.
* No special computer requirements (we will
use ship PCs and bring our laptops)
* Foreign nationals will be UNH students.
* Point of Contact is Frank Bub.
* I would make the area for cruise
desciption entry a little bigger.
* Can you send a back-copy of this submission
for our records? Thanks - FLB
