Arrival port & date:4 July 1998
Op area:Endeavor/Middle Valley/CORK Sites
Depth range:2000-2600
    Will the vessel be operating within 200 NM of a foreign country?
    Which country?
    Are visas or special travel documents required?

Funding agency:

Grant or contract number: multiple

    Science objectives/activities planned:
1. Chave/Van Dover (6 dives): ALISS camera imaging at selected vents in the Endeavor main vent field. This requires securing all Alvin external lights
after submarine positioning. Ancillary science includes biological and geological sampling, deployment and recovery of settlement experiments,
vent water sampling, and testing of a hydrogen probe. Acoustic navigation using existing transponders will be required, and must be coordinated
with ROPOS operations from Thomas Thompson nearby.

2. Lilley (2 dives). Water sampling in Middle Valley and servicing CORK sites 857D and 858G, including acoustic data downloading.
Acoustic navigation required using existing net.

3. Becker/Davis (1 dive). Servicing CORK sites 1027C and 1026B, including data downloading and modem installation. Acoustic
navigation is not required if CTFM is operational.

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

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

Long baseline (LBL) transponder navigation? Yes No. of xpndrs/nets: 2 or 3, depending on permanent installations
Ultra-short baseline (USBL) navigation?
Doppler/GPS navigation?

Will you be using portable science vans? No How many:

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

    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?
