    Science objectives/activities planned:
The major objectives of the Galápagos Rift Alvin dives are to:
1. Assess the temporal and spatial changes that have occurred among and within Galápagos faunal assemblages through a detailed mapping and sampling program.

2. Correlate observed variations in faunal and microbial assemblage composition with observed variations in fluid chemistry, sulfide mineralogy and chemistry, pH, and temperature (i.e., nutrition-related properties of the fluids) via extensive biological sampling and in-situ and laboratory analysis of fluid chemistry and sulfides.

3. Explore the Galápagos Rift for previously undetected high-temperature venting and new vent fields/animal communities using ABE, towed camera systems and CTD tow-yos. Any new discovery will be mapped and sampling using Alvin and ABE.

4. Develop a comprehensive model of vent community succession at the Galapagos Rift sites . Our goal is that the model we develop can be used to guide the design of future studies and manipulative experiments.

Alvin dives at 2-3 primary areas around 86W Galapagos Rift to
revisit the 1977-79 vents
and exploration at 88W or 89.5W
for new vents
ABE surveying during Alvin operations in 86W vent area
and exploration in other areas
night-time CTD rosette tow yos
for vent exploration
night-time digital camera surveys using the CTD coax wire and stbd hydroboom for deployment
possible use of std hydrowire and
rock corer

possible use of trawl winch and dredge

transponder nav will require 2-3 nets - 1 for 86W vents and
others at other areas to be

8 xponders are requested - 2-3 nets

86W area will have 3-4 xponders
to be used by ABE and Alvin.

need a few additional transponders as back up requested total is 10 on board.

WHOI shipboard scientific instrumentation desired:
    12 kHz Transducer
    3.5 kHz Transducers
Fume Hood
XBT SystemRefrigerator
Deionized Water SystemChest Freezer
    Gravity Corer
CTD/Rosette System-70 Deg Freezer
    Rock Dredge
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: 8-10 xponders needed
Ultra-short baseline (USBL) navigation?
Doppler/GPS navigation?

Will you be using portable science vans? Yes How many: 1 - ABE van

Science Van #1
Science Van #2
Science Van #3
see rod catanach

Anticipated standard oceanographic cable use:

Instrument Weight(s)
Maximum Depth
    Conducting hydro
CTD rosette, towed camera
CTD-std wt, camera ~2000#
    Steel hydro
rock corer
    Steel trawl
    .681" fiber optic
    Do you require slip rings?
YesNumber of conductors:for CTD
    Do you need non-standard wire?
NoIf so, what type?
    Do you need a traction winch?
Will you be bringing any equipment (winches, blocks, etc.) that lowers equipment over the side?

If yes, please provide details:
Will there be special requirements for:

    Electrical power
    Equipment handling
    Inter/intraship communications
    Science stowage

If yes to any of the above, please identify: ABE, SeaNet, towed camera (needs CTD hookup) (requires that Alvin small boat be move to 01 deck)

Will any of the following items be used on board?

    Explosive devices
    Portable air compressors
    Flammable gases
    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?
