+--------------------------------------------------------------------------+ | ATLANTIS CRUISE SYNOPSIS | +--------------------------------------------------------------------------+ Voyage - Leg: AT 11-20 Voyage Dates: 05 - 26 Nov 2004 Chief Sci(s): Marvin Lilley (Booksh/Edwards) Address: University of Washington School of Oceanography Box 355351 Seattle, WA 98195 Phone: 206-543-0859 Email: lilley@u.washington.edu Cruise Objective: Booksh Group - Testing of chemical instruments (Raman Spectrometers, resistivity and hydrogen sensors) in hydrothermal fluids. Collection of hydrothermal fluid samples. Bach/Edwards - In-situ incubation studies of Fe and S oxidizing microorganisms on mineral surfaces. Collection of glass, sulfide, sediment and fluid samples. n situ incubation studies of Fe and S oxidizing microorganisms on mineral surfaces. 1) Recovery of incubation baskets at: 9 Deg 50.64504' 104Deg 16.35504' Depth 2564 9 Deg 49.672560' 104 Deg 16.5438' Depth 2545 9 Deg 43.52946' 104 Deg 16.50834' Depth 2537 9 Deg 28.77402' 104Deg 14.5986' Depth 2562 9 Deg 43.58784' 104Deg 15.0639' Depth 2581 9 Deg 50.39868 104Deg 17.49876' Depth 2512 9 Deg 50.4' 104Deg 17.89284' Depth 2516 9 Deg 28.79532' 104Deg 15.60354' Depth 2558 2) Installation of incubators on axis and off axis (up to 1 km) in the 9-o28-9-o50 area 3) Recovery of samples (basalt glass, chimney sulfides, and hydrothermal sediments) and their alteration products 4) Sampling of fluid-solid pairs for heavy stable isotope geochemistry Mullineaux - Night program investigating the temporal variation of larval supply to vent communities using larval pumps and sediment moorings. Specifically, we will need ship time and deck crew support for: 1. Short-term deployment (~ 2 week) and recovery of 2 sediment trap moorings 2. Five separate 24-hour deployments of a plankton pump mooring 3. Deployment at the end of the cruise of 2 sediment-trap moorings and 1 current meter mooring Precise positioning on the seafloor is essential for these moorings. In the past, we have let the moorings free-fall from the ship, and then positioned them with the submersible. Instead, for this cruise, we will be attaching the moorings with an acoustic release to the end of the hydrowire and lowering them to the seafloor. We plan to use ship-based and seafloor navigation systems in order to position the moorings and survey them in.

Science Tools: Raman Spectrometer - Needs 24v Alvin power, RS232 communications. More info to be provived later. Booksh sampler (offload instrument) 12Dx36L, ~250#aw, ~150# ww Additional Lilley ICL connection required (26v,G,Rx,Tx) Shipboard Mullineaux - We will need transponder nav to survey Equipment/Nav: mooring positions, but the net used for Alvin should be sufficient; we may need USBL and Doppler/GPS nav, but are not sure) Bach - We will use existing transponder net to navigate at 9-o50. Will use ship GPS to go to locations at 9-o43 and 9-o28 and navigate sub using GPS survey and DVLNAV. Transponder Nav - Bio Vent to Tubeworm pillar USBL nav Doppler/GPS nav Other Requirements: Night work anticipated Notes: Mooring deployments - 600 lbs Max - 2750 meters max depth Mullineaux - There will be special requirements for equipment handling - especially the anchor-first lowering of moorings on the hydrowire. We will need assistance from the deck crew at night for these lowerings, and from navigation personnel for surveying in positions of the moorings. Agreement has been made with Alvin group to purchase 71 plates for mooring anchors. Mullineaux - We will need space in the hold for shipping crates and assorted boxes We will need space on deck during the cruise for the 2 sediment traps, a cage of glass balls, and (3) 3-ball surface floats Bach - We will need space in the hold for shipping crates and assorted boxes We will need space in the -70 freezer (about 1/3 of volume) and chemical storage van for storage of samples and chemicals until ship docks in San Diego (after Cary cruise) Hazardous materials (Flammable Gases) will be offloaded in San Diego after the following leg. Mullineaux - EtOH ,DMSO, D-cell batteries (we will need help figuring out how to dispose of used batteries at end of cruise) Bach - EtOH, paraformaldehyde, HCl, NaOH Laptops need testing for use in Alvin- next test Oct 20/21 Navy Clearance Status: Approved 10/22/04: WITHIN 30 NM RADIUS OF 09-40N, 104-16W DURING PERIOD 041600Z NOV THRU 200000Z DEC 04 Last Modified: 01/19/2006 Check List: Required?
