    Science objectives/activities planned:
We have three main objectives for this cruise. One is to collect adult invertebrates from vent communities, bring them to the surface alive, and spawn them to produce larvae for shipboard experiments in pressure vessels. A second is to deploy free-standing moorings with plankton pumps attached, in order to collect larvae from near-bottom waters and retrieve them alive. The third is to use the 'Laredo' sampler to collect microbes from high temperature fluids. A variety of ancillary studies will also be conducted. Recruitment blocks will be recovered and, possibly, deployed. An in-situ freezer for Alvinellids will be tested (H. Felbeck, SIO). Animals will be collected for a variety of studies. Current-meter moorings will be deployed and recovered. Video and still cameras will be used to characterize communities at vents.

WHOI shipboard scientific instrumentation desired:
    12 kHz Transducer
Fume Hood
Deionized Water SystemChest Freezer
-70 Deg Freezer
Pinger for Wire Use

Is nighttime work anticipated on this cruise?

    Critical MET sensors:
    Critical CTD sensors:

Do you need Seabeam? (AT and KN only) No

Long baseline (LBL) transponder navigation? Yes No. of xpndrs/nets: one net to cover Nav between 'Biovent' (9 51N) and 'Worm Hole' (9 49N)vents;
Ultra-short baseline (USBL) navigation?
Doppler/GPS navigation?

Will you be using portable science vans? Yes How many: we'll be using the storage vans where we stored gear last May

Science Van #1
Science Van #2
Science Van #3

Anticipated standard oceanographic cable use:

Instrument Weight(s)
Maximum Depth
    Conducting hydro
    Steel hydro
    Steel trawl
    .681" fiber optic
    Do you require slip rings?
NoNumber 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?

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: Mooring deployments will require capstan and crane. We plan to load gear in San Diego (Nov. 1999)

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? 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?
