Science objectives

This proposal will seek to charaterize the geology, geochemistry, microbiology and macrobiology of two new hydrothermal fields on the Mid Cayman Rise - the Piccard hydrothermal field at ~5000m depth near 18deg33min N, 81deg 43minW and the Von Damm hydrothermal field at ~2300m depth near 18deg23min N, 81deg48minW

Science Activities

1) Deployment of transponders for LBL at one or both sites
2) Jason-based Geophysical surveys (Reson + Gravity ± Magnetics) at each site (24h)
3) Jason-based sampling (5-6 days at each site) to include: fluids (Seewald +/- Major pairs); sulfides (young with fluids and older); rocks; push cores; microbial mats (pumps including Chip Breier's SUPR sampler); macro-biology (shrimp, tubeworms, gastropods, other vent-endemic fauna, fish)
4) CTD operations including use of SUPR sampler mounted on CTD-rosette
5) Multibeam mapping of seafloor +/- imaging for plumes using new ship's multibeam (effective to >2000m on Juan de Fuca in 2011)

Navigation


Will you be using Long Base Line (LBL) navigation? no

Will you be using Ultra-short baseline (USBL) navigation for other than Alvin operations? no

Navigation

GPS
LBL
USBL

Navigation Notes: Both LBL and USBL useful for Jason nav at these depths

Winches

CTD Winch with .322" Electro-mechanical wire
Trawl Winch with .681 fiber optic

Winch Notes: Only Jason and CTD operations are anticipated this cruise

Wire use and application

CTD Winch with .322" Electro-mechanical wire
Trawl Winch with .681 fiber optic


Wire Notes: SUPR sampler mounted on CTD rosette frame or on Jason. For CTD ops, we would like to use the adsl model package put together by Marshal Swartz - to do so all 3 conducting wires of the CTD seacable must have full conductivity.

On the CTD the SUPR sampler will have these weights: 60 kg in water, 100 kg in air
On Jason the SUPR sampler will have 2 configurations
Config. A (1 unit) 15 kg in water, 30 kg in air
Config. B (3 units) 45 kg in water, 118 kg in air - includes 28 L of water

The Mat Sampler (Breier's) will also be used by Huber and Breier on Jason and weighs 25 kg in water and 50 kg in air.

Specialized tech support (Seabeam, coring, other): CTD operations will be led by J.Breier (AOP&E, WHOI)
We also anticipate wanting to conduct at least some multibeam surveys, over the known vent sites, to examine for active fluid flow signals using the new shipboard multi-beam, to be led by J.Kinsey (AOP&E, WHOI)

Other required equipment and special needs: 

Gravimeter (Kinsey)--- Need for shipboard gravimeter will not be finalized until Nov 2011.  J. Kinsey, the requesting scientist, runs the UNOLS gravimeter pool (from which this gravimeter will be supplied) and can thus handle all of the shipping and installation. Some SSSG support will be required for installation.  If installed, the gravimeter will ride the Atlantis back to Woods Hole and be off-loaded there.
