    Science objectives/activities planned:
The work plan is as follows: The vessel will loaded 16 & 17 January, depart from WHOI 18 January, and make way for a target location just south of the Gulf Stream, at a longitude near 70oW. After making our first CTD cast, we will then prepare to deploy the compound spar, “S” (below), the largest single deck item on the vessel.

After deployment, our efforts will be to zig-zag across the Gulf Stream, following the compound spar as it drifts downstream, making CTDs, radiosondes, and launching floats & drifters as required.

After ca. 10 days, we would recover the compound spar, occupy a CTD station at the location of the surface meteorological buoy “F”, presently being deployed on Oceanus (target location is: 38.5N, 65W ), and return to port on 31 January.

The actual cruise scenario will depend on the location & structure of the Gulf Stream during the cruise, as given by daily satellite data.

Major activity categories:

- Occupy ca. 90 CTD stations to 1000m depth (Joyce, Talley, Lozier)

- Deploy ca. 20-25 Radiosondes, shipboard air-sea fluxes from mast (Edson)

- Deploy & recover AirSea Interaction Spar (Edson) and tethered moored profiler (Toole)

- Deploy subsurface bobbing, acoustic floats (Fratantoni)

- Deploy surface ‘holey sock’ drifters (Lumpkin)

- ADCP profiling using 75 kHz Ocean Surveyor (Joyce)

See "other comments" below for critical items.

    Do you require slip rings?
YesNumber of conductors:3
    Do you need non-standard wire?
If 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:

Will any of the following items be used on board?

    Explosive devices
    Portable air compressors
    Flammable gases
    Radioisotopes

Will hazardous material be used aboard, or deployed by an ROV? Yes

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?
Hazardous materials may be used by the SIO/ODF groups for oxygen titration and nutrient analysis. They will provide the inventory for these.
All hazardous materials will be removed from the ship upon return to WHOI at the end of the cruise.
