    Science objectives/activities planned:
service instrumentation at up to seven subseafloor “CORK” hydrological observatories installed by ODP in 1996 and IODP in 2004;
2) make in situ, shipboard and shore-based measurements to characterize the microbial geochemistry of the subseafloor basement (basaltic crust) utilizing subset of above 7 CORK observatories; and
3) test underwater optical communication device associated with a temperature probe deployed within a thermal vent

WHOI shipboard scientific instrumentation desired:
    12 kHz bathymetry system
Oxygen titration apparatus
    3.5 kHz bathymetry system
Fume hood
Refrigerator
Deionized water systemChest freezer (OC and KN only)
CTD/rosette system-70 deg freezer
Walk-in cooler (AT only)
10-liter Niskin bottles
Pinger for wire use

Is nighttime work anticipated on this cruise? Yes

    Critical MET sensors:
    Critical CTD sensors:

Do you need Seabeam? (AT and KN only) Yes

Long baseline (LBL) transponder navigation? Yes No. of xpndrs/nets: 3/net; 1, possible 2 nets
Ultra-short baseline (USBL) navigation?
Doppler/GPS navigation? Yes

Will you be using portable science vans? Yes How many: 1 WHOI radioisotope van

    .681" fiber optic
    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? Yes

If yes, please provide details: The Fisher et al. group will be bringing out a custom winch system to be deck mounted for recovery of observatory instrument strings with a Spectra line. This is to be the same system fielded in Sept. 2007, but it is being refurbished/redesigned by the vendor in Seattle. Co-PIs Wheat and Jannasch are preparing a document describing winch operations, which we will forward for discussion with Alvin/Atlantic staff.
Will there be special requirements for:

    Electrical power
No
    Equipment handling
No
    Inter/intraship communications
No
    Science stowage
No

If yes to any of the above, please identify:

Will any of the following items be used on board?

    Explosive devices
No
    Portable air compressors
No
    Flammable gases
No
    Radioisotopes
Yes
    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?
Various reagents typically used at sea will be used during the cruise. A complet list will be furnished a later date prior to cruise. (examples include formaldehyde, mercuric chloride, hydrochloric acid).
