+--------------------------------------------------------------------------+ | ATLANTIS CRUISE SYNOPSIS | +--------------------------------------------------------------------------+ Voyage - Leg: AT 15-15 Voyage Dates: 10 Jan - 05 Feb, 2007 Chief Sci(s): Timothy Shank, Costa Vetriani (Lutz/Vetriani/Luther/Shank/Tolstoy) Address: Timothy Shank, Costa Vetriani (Co-Chief Scientists) Woods Hole Oceanographic Institution MS 33 Biology Department Woods Hole, MA 02543 Phone: 508-289-3392 Email: tshank@whoi.edu Cruise Objective: The specific objectives of our program are to: (1) determine the post-eruptive distribution of hydrothermal activity and nascent biological assemblages; (2) examine the temporal and spatial changes in benthic communities through in situ observations, sampling, and manipulative experimentation; and (3) correlate of changes in faunal community structure with variations in microbial community composition, in situ fluid chemistry, pH, and temperature. Science Activities: To this end, in situ voltammetric sensor devices (both autonomous and mounted directly on DSV Alvin) will be used to measure a variety of chemical species, including H2S/HS-, FeS, Fe2+, Mn2+, O2, pH and temperature over time in a variety of nascent vent habitats as well as those associated with colonization substrates specifically designed for temporal co-located and integrated comparisons of microbial community structure, fluid chemistry, and macrofaunal colonization. We will deploy a large volume water pump for microbial collection, colonization substrates, in-situ electrochmical sensors, seafloor markers, and OBS arrays. We will recover colonization substrates and OBS arrays. We will sample fauna and rocks, and conduct detailed educational and outreach activities in conjunction with the R2K program.

Downlooking surveys using a digital camera may require strobes with a retractable boom as configured in April 2004 and June 2005. Camera settings should be established ahead of time 2. Magnetometer as used in June 2005; mounted on the sail. 3. Note that we require a slurp sampler sufficient for the collection of vent fish. We are currently working with engineers to try to help make this happen. Program-Provided 1.

The AIS electrochemical sensor. The weight and size has been reduced since April 2005. Wiring is the same. Need wiring schematic. Sensor - 2 systems total - 12 wires total - RS422 (2 TSP) - +/- 12 vdc power - any pressure vessels ? - air weight 40 lbs each - water weight 22 lbs each RS422/RS232 Converter - already gas tested - air weight ??? Laptop Computer - already gas tested - air weight ??? 6. An RNA collector device (in two configutaions) will be used- one similar (if not identical) as was used in April 2005 (configuration 1 weight= 5lbs in air/2 in water' configuration 2 weight= 16 in air/8 in water) - requires 2 Pelagic pumps 7. Marker Holders - 8 markers per holder - Water weight ???? - Dimensions/drawing/picture ???? 8. Pressure/Tide Gage (SeaBird-26 tide gauge) -(from Response Cruise - to be recovered by Alvin) -total weight of the package (CTD plus fiberglass tripod cradle) is 56lbs in air and 27lbs in sea water. The unit has been Alvin certified - Sonardyne Homer probe beacon mounted on the tripod (code # 70) - Will require a weight to be released prior to recovery by Alvin 9. `Insect' - New comms device - small housing - +/- 12 vdc - TX+, TX-, RX+, RX- - Dimensions/drawing/picture ???? - Water weight ????? - Interconnection Wiring Diagram ???? 10.

TowCam (1/4-JD) Items to be used in the sphere Laptop computers Digital SLR and video cameras (already gas tested) Shipboard Equipment/Nav: Other Requirements: Science party will have ~ one -70deg freezer of samples all samples will be removed at the end of the cruise. Chems/hazmats will be removed in San Diego in April. Loading in Manzanillo: Tolstoy will send one 20' container from UCSD to Manzanillo, contents will be unloaded onto ship Hazmats will be compressed gases for use by Vetriani's group (Nitrogen, and a Carbon Dioxide/Hydrogen mix). Gases and MSDS/Hazmat forms were loaded in San Diego in October. We anticipate at least 10 nights of TowCam operations (could be as many as 15 or 17 nights).* Marshall Swartz, who will be sailing as SSSG and occupying SSSG berthing, with direction from Dan Fornari, Adam Soule, and myself, will conduct these operations. Our night program will consist of three elements: CTD casts (perhaps 4 to 5) Recover OBSs (perhaps 5) TowCam surveys (perhaps 10-15) Per our previous discussions, we will also deploy elevators as needed for our Alvin program (e.g., ISEA, water sampler, etc.) Notes: Navy Clearance Status: Granted 12/27/06 WITHIN 50 NM RADIUS OF 09-40N 104-13W DURING PERIOD 100700Z JAN THRU 070700Z FEB 07 Last Modified: 02/01/2007 Check List: Required?
