+--------------------------------------------------------------------------+ | ATLANTIS CRUISE SYNOPSIS | +--------------------------------------------------------------------------+ Voyage - Leg: AT 11-27 Voyage Dates: 19 May - 3 Jun 2005 Chief Sci(s): Timothy Shank (Shank) Address: Woods Hole Oceanographic Institution MS 33 2-14 Redfield Building Woods Hole, MA 02543 Phone: 508-289-3392 Email: tshank@whoi.edu Cruise Objective: Specifically, our objectives are to: (1) biologically characterize and chemically "map"in detail the Rosebud site and its microhabitats through the in-situ characterization of temperature, pH, and other physiochemical parameters that link with microbial biofilms and the colonization of different invertebrate species; 2) conduct comparative quantitative digital image surveys of the vent field to assess the changes in community structure that have occurred since May, 2002. Image results extracted from our constructed photomosaics and detailed imaging surveys of the Rosebud vent field in 2002 revealed that this site consists of 4 major venting areas containing vestimentiferan tubeworms (majority less than 6 cm in length), linear rows of bathymodiolid mussels (average ~1cm in length) growing along cracks in the sheet lava surface, and adjacent carpets of amphianthid anemones (ca. 50 per square meter); (3) install a suite of time-series instruments to assess correlations in the structure of the various vent communities with species-specific larval presence (through time-series larval collectors), larval settlement (through basalt panel, time-lapse camera and temperature probe array deployments), and vent fluid temperature and chemistry (through autonomous in-situ measurements; and (4) conduct a night exploration program that employs towed camera surveys/CTD surveys to explore for undiscovered high-temperature venting (a phenomena enigmatically unobserved to date on the Galapagos Rift) as well as other historic vent sites, including the once well-known Musselbed site (8km from Rosebud) to determine if and how it might have been affected by volcanic activity.

We would like the Insite camera system with strobe oriented in a forward-looking position in order to optimize it for future use. Notes: We anticipate having only ethanol and formalin on board, and will dispose of these in Seattle, the next US port. Internal sphere equipment will need gas testing - Additional information on this will be forthcoming.
