The overall objective is to better contraint and characterize chemolithoautotrophic processes at vents. We will be primarily sampling diffuse flow vent fluids, but also black smoker chimeny and basalts. We also plan to deploy a large volume pump on an elevator for in situ filtration of diffuse flow fluids. Seyfried - Instrument testing, deployment and recovery. In-situ chemical measurements in diffuse and focused flow hydrothermal fluids. Water and sulfide sampling. Science Activities: Operations Area: Sievert - mainly bulls eye area at 9.50N - We will work primarily in the in the bulls eye area and possibly one off axis site. distance to off axis site < 1 day Seyfried - bulls eye area at 9.50N 9 30-56'N, 104 12-20'W 2500-2700 m Departure Port: Manzanillo, Mexico Agent: Primary Agent: Vasile Tudoran Transport 819 Ohio Ave. Long Beach, CA 90804 Contact: Vasile Tudoran Phone: (562) 882-5590 Fax: (562) 434-9800 Email : [1]vtudoran@aol.com Subagent: Master R/V Atlantis Attn: Scientist's Name IN TRANSIT MANZANILLO MEXICO c/o Continental Maritime SA 83 Calle Colhuas, Centro 28200 Manzanillo, Colima MEXICO Contact: Daniel Arias Romo Phone/Fax: 011 52 314 33 21223 Cell: 011 52 314 100 8862 Email: [2]danielromo2003@yahoo.com.mx Arrival Port: San Diego, California Agent: Master R/V Atlantis Attn: Scientist's Name c/o Paxton, Shreve & Hays Inc. 2191 Main St. San Diego, CA 92113 Contact: Tom Jenkins Phone: (619) 232-8941 Fax: (619) 232-3006 Telex: 6731029 SHREVE SDG Email: [3]marineops@pshinc.net SHIP Installed or Normally Relay Transponder for wire work Carried Equipment: 3.5 kHz Bathymetry Deionized Water System CTD/Rosette 23X10L - temperature, salinity, density, oxygen, fluorescence, transmission (5-10 total for cruise (EC 10/26)) Pinger for wire use Fume Hood Refrigerator -70 Deg Freezer (freezers Sievert (EC 10/26)) Walk-In Cooler Seabeam Underway Sea water system (EC 10/26) WHOI-Provided Equipment: Isotope Van Science Party-Provided McLane large volume pump - ~120 lbs in air to a Equipment: max depth of 2500m 150L Liquid Nitrogen to be reflilled (EC 10/26) Notes: Night Work Anticipated a) Hazardous material will be accompanied by the respective spill kit. b) We plan to take chemicals, waste, and gases off the ship at the next US port. ALVIN/JASON Installed or Normally Major Water Sampler Carried Equipment: Large Capacity slurp pump (EC 10/26) small capacity slurp pump bio box (12x12x12 & 12x12x24) High & Low temperature probe Magnetometer CTD Digital Still Camera (Fwd looking) Seach Sonar Profiling Sonar Elevator USBL Navigation Doppler/GPS Navigation Science Party-Provided Sievert - A McLane in situ large volume pump is Equipment: going to be deployed as an elevator. It is planned to bring the pump close to the deplyment site the night before a dive by wire and then to position at the site with Alvin the next day. Either on the same dive or the following dive Alvin is going to release the pump. This procedure has been tested very succesfully on previous cruises, the latest being AT15-15. For the deplyment of the pump we will need weights (5 plates) and floats (4 spheres). We plan for a maximum of pump 8 deployments. Deployments will use relsease and deck box from Mullineaux cruise. (EC 10/26) 1 elevator deployment (EC 10/26) Possibly Autonomous Microbial Sampler (AMS): may not go on the cruise. The dimensions of the cage are 49.5 cm (19.5'') wide x 46 cm (18'') deep x 56 cm (22'') high, and the instrument weighs 38.6 kg (85 lbs) in air when the ISC contains no water and 46.7 kg (103 lbs) in air with the ISC full of water, which would be the typical weight when handled on deck. The instrument weighs 16 kg (35 lbs) in freshwater or 15.4 kg (34 lbs) in seawater (ISC full of water). Needs connection to inside. In situ chemical analyzer (be used by Nadine LeBris) specifications to follow. needs connection to inside. 2 laptop computers (Sievert, Le Bris) to be used in the sphere. has been tested (EC 10/26) Seyfried - We will provide Alvin with four Impulse RMG-4FS cables (bare wire on Alvin end). Alvin needs to provide + 26 V and RS232 communication to all four cables. These will be used interchangeably by many of the science instruments planned for this cruise. We need the capability to operate four instruments simultaneously. Chemical sensor data loggers (15 lbs), Seewald-type gas tight samplers (20 lbs). All are water weights. Ding/Seyfried: needs 4 RS232 penetrations. Bill & Kang will supply cables. Equipment sent to be pressure tested at WHOI Oct 5th.
