Oceanography, University of California San Diego, La Jolla, CA 92093-0244 Phone: Brown - 858 534 5368 Tryon - office: 209 Vaughan Hall (858) 822-0591 Tryon - lab: 244 Vaughan Hall (858) 534-6961 Email: Tryon - mtryon @ucsd.edu Brown - kmbrown @ucsd.edu Cruise Objective: Brown - Instrument pick-up and push coring for biological samples and (re) surveying of seep sites. Science Activities: Alvin Dives and CTD casts recovering 7 ocean bottom instruments via acoustic release and doing 2 Alvin dives to resurvey the deployment sites, take tube cores, and collect animals and a few rocks. There will also be 1-3 CTD casts to as close to the bottom as is reasonable (1000 to 1050 meters), primarily to profile oxygen for the biologists Operations Area: Brown - 8oN55.45; 84W18.45 - 1000m-1800m SSSG Tech: sssg @atlantis.whoi.edu Departure Port: Balboa, Panama Agent: Master R/V Atlantis Attn: Scientist's Name IN TRANSIT c/o Panama Agencies Co.

Request 12khz hull transducer connection to science provided Edgetech deck unit to release instruments. Other Requirements: 17" Hard Hat float for Instrument pickup if release fails (requires 2 balls/pickup) Notes: Science party will leave equipment and samples onboard to be off-loaded in San Diego after EPR eruption response cruise, need 1cu ft of -70 space (EC 5/23) Instrument recoveries: Recoveries have to be done in daylight - radio beacons and flags but no strobes. We have 2 sites separated by about a kilometer with 2 instruments on site A and 5 on site B. We want to recover the 2 at A before the first dive so that if there is a release failure we have the option of using Alvin to recover. Similarly for site B. Assuming we leave Balboa in the am we should be on site A before dawn (1.75 day transit) and will have time for the first two recoveries before the dive: Sunrise is 0517, instrument rise time is about 25 minutes. After the dive we should have time to recover 2 to 3 of the instruments at B (sunset at 1800). The following morning we can recover the rest of them before the dive. If an instrument release fails we would prefer to bring down floats on a tether to float it up rather than bringing it up on Alvin's basket. Alvin ops: We will not have a transponder array - doppler is good enough. The two sites are well navigated and there should not be problems finding them. We will visually survey the sites to look for any changes in them and collect tube cores, animals, and maybe a rock or two. We would like two racks of cores, 24 total for each dive. We also need bio box and scoop nets. If time permits we will also do a few low temperature heat flow measurements in the sediment. We will not need major bottles or slurp pump. CTD cast: We would like to do 1-3 casts over the sites, primarily to profile oxygen, in between the dives at whatever time is convenient to Dave.
