    POC / contact info:
Departure port & date:Manzanillo, Mexico, Dec 27 2007
    Distance to first station:
~2.5 days
    Number of stations:
We will work primarily in thework in the bulls eye area and possibly one off axis site.
    Distance between stations:
distance to off axis site < 1 day
    Total days on station:
Arrival port & date:not determined yet
Op area:mainly bulls eye area at 9.50N
Depth range:2500-2900 m
    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: Sievert: OCE-0452333

    Science objectives/activities planned:
The focus of the activities by the Sievert group will be microbiology. The overall objective is to better contraint and characterize chemolithoautotrophic processes at vents. We will be primarily sampling diffuse flow vent fluids, but also black smoker chimeny and basalts. We also plan to deploy a large volume pump on an elevator for in situ filtration of diffuse flow fluids.

Fume hood
    Relay transponder for wire use
Deionized water systemChest freezer (OC and KN only)
CTD/rosette system-70 deg freezer
Walk-in cooler (AT only)
Pinger for wire use

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?
a) Hazardous material will be accompanied by the respective spill kit.
b) We plan to take chemicals, waste, and gases off the ship at the next US port.
