    Power

Anticipated standard oceanographic cable use:

Instruments(s)
Instrument Weight(s)
Maximum Depth
    Conducting hydro
regular CTD Niskin rosette
    Steel hydro
    Steel trawl
    .681" fiber optic
    Do you require slip rings?
Number of conductors:
    Do you need non-standard wire?
YesIf so, what type?Hytrel coated Vectran (bring our own)
    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: We have arranged with SSSG to use Frank Bahr's SeaSoar SeaMac winch to deploy up to 11 battery-operated in-situ pumps using our own plastic-coated non metallic wire (1000m). If possible, we would like to place this winch on the 01 deck and deploy off the hydroboom. We have also asked to use the non metallic metering block that SSSG has.
Will there be special requirements for:

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

If yes to any of the above, please identify: The 11 in-situ pumps each have a shipping crate ~3'x4'x2' to store

Will any of the following items be used on board?

    Explosive devices
No
    Portable air compressors
No
    Flammable gases
No
    Radioisotopes
No
    Isotope van
No

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?
a) We will bring emergency spill kits for the acid and base we will be using.
b) acids and bases will be neutralized for disposal at the end of the cruise.
