+--------------------------------------------------------------------------+ | ATLANTIS CRUISE SYNOPSIS | +--------------------------------------------------------------------------+ Voyage - Leg: AT 12 Voyage Dates: 20 (~13:00) - 31 Oct 2005 Chief Sci(s): Lauren Mullineaux (Babb/Watling/Adkins/Rohwer) Address: WHOI MS34 Woods Hole MA 02543 Phone: 508 289-2898 Email: lmullineaux@whoi.edu Cruise Objective: Mullineaux - The objective of this study is to determine how coral communities form and persist on deep seamounts, in order to understand the dynamics of the component populations and their susceptibility to disturbance. To accomplish this, we need to know where and when communities form, how often they are recolonized, and whether subsequent colonists are supplied by the local populations or immigrate from remote sources. Watling - The recent discovery of deep water corals along the continental shelves and slopes of the United States have ignited strong public interest in their conservation. Many of the corals are long lived and others, especially those that form large bioherms, may be important habitat for a variety of invertebrates and fish, some of the latter of commecial importance. However, at the present time knowledge of the occurances of deep corals in the U. S. is still imperfect so finding areas to target for conservation may involve best guesses or limiting ourselves tot he sites already known. Science Activities: Mullineaux/Adkins group: Collect deep water corals (scleractinians and gorgonians) and image communities and habitat on Balanus seamount. Deploy colonization surfaces for long-term recruitment study. Watling/Auster group: Collect deep-water corals and image communities and substrate. Also measure deep water temperatures and salinity. Rohwer group - Collect deep water corals and incubate them in situ in order to identify, enumerate and measure metabolic activities and growth rates of associated microbes. Chambers have been developed that allow incubation of coral fragments with various substrates and labels at depth. These samples will then be preserved (at depth) before being brought to the surface for onboard microscopic analysis. Operations Area: Balanus seamount, Physalia seamount, and continental slope of Georges Bank 39-23'N 65-23'W, ~39-51N 66-55W, and 40-10' to 40-30'N and 68-10' to 67-10'W 500 to 4000 m SSSG Tech: sssg@atlantis.whoi.edu Departure Port: Woods Hole, MA Agent: Master R/V Atlantis Attn: Scientist's Name c/o WHOI 266 Woods Hole Rd.

Would like to try using 12kz pinger and USBL to position current meter during drop from wire. Pinger for wire use Deionized Water Fume Hood Refrigerator Walk-In Freezer -70 Deg Freezer Walk-In Cooler (~4c for cold water w/samples storage) IMET Sensor Anti-vibration microscope table WHOI-Provided Science ALVIN Group Tools: Small capacity slurp pump, large capacity slurp pump with multichambers as backup Bio Collection Box - 12X12X24, 12X12X12 Push Core (~1 per dive, cores to be saved and frozen intact) Scoop Nets Low Temperature Probe CTD 1.2 L rack of niskin bottles Alvin External Digital Still Camera - Oriented down with strobes Search Sonar Profiling Sonar (logged for post processing) USBL Navigation Doppler/GPS Navigation with sub surveyed at start of dive (and end if time/power permit) Program-Provided Fornari Tow Cam Science Tools: Coral incubators Shipboard Equipment/Nav: Other Requirements: Night Work Anticipated: tow camera and Seabeam Rohwer group will be bringing two incubators for microbial measurements. Overall dimensions of each are L-17", W-8", H-18"; dry weight 16 lbs and wet weight ~ 6 lbs.Chambers are aluminum base with polycarbonate containers, stainless hardware. These incubators were sent to Woods Hole for Alvin group input. Notes: Mullineaux and Watling groups will remove hazardous materials back to their laboratories for disposal. Rohwer group will contact you with their plan Watling group may have cameras needing gas testing Navy Clearance Status: Granted 10/17/05: WITHIN 20 NM RADIUS OF 39-24N 65-24W DURING PERIOD 200400Z THRU 290000Z OCT 05 WITHIN 10 NM RADIUS OF 39-50N 66-57W DURING PERIOD 200400Z THRU 310000Z OCT 05 WITHIN 30 NM RADIUS OF 40-10N 67-40W DURING PERIOD 200400Z THRU 310000Z OCT 05 Granted 10/25/05: WITHIN 10 NM RADIUS OF 39-50N 66-14W DURING PERIOD 260400Z THRU 310000Z OCT 05 WITHIN 10 NM RADIUS OF 39-39N 65-58W DURING PERIOD 260400Z THRU 310000Z OCT 05 WITHIN 10 NM RADIUS OF 39-53N 67-25W DURING PERIOD 260400Z THRU 310000Z OCT 05 Last Modified: 01/19/2006 Check List: Required?
