    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: We plan to put gear on and off in San Diego, we may need use of a gear elevator

    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?

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:
    Electronic equipment used in the ALVIN personnel sphere:
    Other comments and information:
    Do we have access to ROV's without extra charge?
    One of our sites is at 4950 m - can Alvin go this deep?
    An ROV would be helpful, but we have no extra funds
    We plan to supply gravity and box cores from Scripps (loaded in June)
    Can you tell me what frequency Alvin can hear from a deep transponder (short term)
    Does ALVIN's CTD have an oxygen sensor?
    Does ALVIN provide a free nisken bottle.
    Is any new sampling gear available?

    I have not used ALVIN since 1991 and would like to know what has changed and what new facilities are available.
    Also, I have never used the new Atlantis - so information about items already there (fume hood?) would be helpful.
    Because of the unusual nature and late notice for this NURP program we are on a shoestring budget AND tight schedule.
    Most of us are getting off the R/V Sproul on July 29th and have to bring some gear to Kodiak.
    We are assuming 24 hr ship ops including nighttime coring - is this available?
