    Science objectives/activities planned:
Fisher: Main purpose of this part of the expedition is to service subseafloor observatories. This involves using the submerisble, Alvin, to download data and recover and deploy sampling instrumentation. Observatories to be accessed were emplaced during ODP Leg 168 (1996) and IODP Expedition 301 (2004), serviced with ROPOS in 2004, then serviced with Alvin in 2005, 2006, 2007, 2008. The primary goals that motivated these experiments are hydrogeological, geochemical, microbiological, and geophysical.

Lee: Six Alvin dives will be made at Axial area to study the thermal biology of vent paralvinellid worms. Generally, small collections of macrofauna 10 x 10 cm area (30 to 200 grams of biomass) will be made in high, moderate, and cool temperature environments on chimney structures in the vent field.

WHOI shipboard scientific instrumentation desired:
    12 kHz bathymetry system
    3.5 kHz bathymetry system
Fume hood
    Relay transponder for wire use
Refrigerator
Deionized water systemChest freezer (OC and KN only)
CTD/rosette system-70 deg freezer
Walk-in cooler (AT only)

Is nighttime work anticipated on this cruise? Yes

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

Long baseline (LBL) transponder navigation? Yes No. of xpndrs/nets: 1 @ 1301/1027/1026
Ultra-short baseline (USBL) navigation? Yes
Doppler/GPS navigation? Yes

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

Maximum Depth
    Conducting hydro
    Steel hydro
    Steel trawl
    .681" fiber optic
    Do you require slip rings?
NoNumber of conductors:
    Do you need non-standard wire?
NoIf so, what type?
    Do you need a traction winch?
No
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 2008, when it worked well for all operations. Custom system preloaded with Plasma line that was designed specifically for CORK instrument string recovery.
- Overall dimensions are 5 ft x 6 ft.
- Deck dimensions are 4 ft by 6 ft. where it lands on the deck, meant to fit UNOLS bolt pattern
20 hp, and is expected to draw about 25 A @ 480V 3ph.
will be mounted under the port boom like 2007, 2008

Additional gear being prepared
Wheat:
• 36" snatch block with 2" minimum throat (MBARI)
• sinker bars and floatation
• drop weights and landing shoes
• Nylon thimbles for terminating eye splice in primary member at the osmoshackles end (to be made up on board)

Becker
• ~320+ lbs of floatation
• a couple spare yale grips for extra lifting points if necessary
Will there be special requirements for:

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

If yes to any of the above, please identify: Power for winch above, bringing instruments, weights, floatation over the rail in evenings

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