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
Lat/Lon:
Depth range:2500-2900 m
    Will the vessel be operating within 200 NM of a foreign country?
    Which country?

Funding agency:
      NSF
Specify:

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.
