    Other vehicle-related equipment (list):
    Science equipment to be installed on vehicle:
    Electronic equipment used in the ALVIN personnel sphere:
    None
    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?
