    Science objectives/activities planned:
The scientific objectives of the project are: (1) to understand the exchange of mass and properties across the East Greenland shelfbreak, including the role of atmospheric forcing due to storms; and (2) to clarify the source of water comprising the Denmark Strait Overflow water.

The primary activities on the cruise are: (1) recover 8 moorings that were deployed last fall; (2) carry out a hydrographic/vmadcp/VPR survey of the region; (3) make atmospheric measurements, with enhanced sampling during storms.

I would like to stress that we are working in the area of the North Atlantic storm track in the fall season, so we expect heavy weather. We will also be working close to the marginal ice zone during part of the cruise. In particular, we may occupy hydrographic sections on the shelf right up to the edge of the pack ice.

WHOI shipboard scientific instrumentation desired:
    12 kHz bathymetry system
ADCP - 75 KHz
ADCP - 150 KHz
XBT system
CTD/rosette system
10-liter Niskin bottlesMET sensors:

    Do you require slip rings?
YesNumber of conductors:
    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? Yes

If yes, please provide details: Mooring winch (this is the same winch that Craig Lee will use on the previous leg).
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 will recover 8 moorings, and the hardware (top floats, glass balls, etc) need to be stowed.

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?

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?
