    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: Complex - see comments at end of form
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

Anticipated standard oceanographic cable use:

Instrument Weight(s)
Maximum Depth
    Conducting hydro
    Steel hydro
possible elevators ?
300 lbs in water
2700 m
    Steel trawl
    .681" fiber optic
MPL Control Vehicle
2700 m
    Do you require slip rings?
Number of conductors:
    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: use of MPL Control Vehicle at nights; recovery of CORK instrument strings (see comments below)

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
Scoop nets
High temperature probe
Low temperature probe
Heat flow probe
Portable CTD
Digital Still Camera
Search Sonar
Profiling Sonar
Rock Drill (Jason only)
Video Duplication (Jason)
    Other vehicle-related equipment (list):
    Science equipment to be installed on vehicle:
through-hull penetrators for
(1) CORK top-hat connector (3 conductors, approx 40 lbs in water)
(2) Seyfried electrodes

Wheat fluid samplers
various equipment just carried in basket:
mini-cone for CORKs (supplied by Wheat et al), acoustic modems recovered from 2 CORKs (150 lbs), CORK logger running, latching and reseating tool (the last containing an atmospheric-pressure chamber and already certified and used on Alvin in 1995)
    Electronic equipment used in the ALVIN personnel sphere:
CORK data recovery laptop and backup already tested, with certificates
    Other comments and information:
Transponders very complex for whole cruise - separate MPL net plus Alvin net needed at 3 CORK locations, Alvin xponders may be needed at 4th. If Alvin CTFM working, some Alvin xponders may not be needed. Also, we may be able to utilize Cowen/Johnson JASON xponders if they can be left installed.
Recovery of CORK sensor strings pulled up by CV: Recover CV, then CORK data logger (300 lbs) then attached sensor string ranging from 140 to 650 m in length and terminated with fluid samplers and sinker bar (200 lbs). We will bring cable grips and 2 special cable handling tools, probably need to use crane to lift and recover 10 m at a time. Will need help of bosun and crew for these operations!
