+--------------------------------------------------------------------------+ | OCEANUS CRUISE SYNOPSIS | +--------------------------------------------------------------------------+ Voyage - Leg: OC 413 Voyage Dates: 23 May -12 Jun 2005 Chief Sci(s): Brian Binder (Binder) Address: University of Georgia Dept. Marine Sciences University of Georgia Athens, GA 30602-3636 Phone: 706-542-6408 Email: bbinder@uga.edu Cruise Objective: The primary objective of the project is to examine the relationships between growth rate, grazing mortality, and relative abundance for two pico-phytoplankton groups (Prochlorococcus and Synechococcus) in surface waters of the Sargasso Sea. On-board flow cytometry will be used to assess the abundance of these phytoplankton. A suite of experimental approaches for measuring growth and grazing mortality in natural picoplankton populations will also be applied. Science Activities: This work will involve both on-deck incubations and intensive water-column sampling. For incubations, trace metal-clean Go-Flo samples will be required (see Other Comments, below). For the water-column measurements, CTD casts will be repeatedly made in the vicinity of a free-drifting drogue (see Other Comments); drogue deployments will last ~36 hr. Operations Area: We plan to occupy 2 or 3 major stations, with 1 or 2 drogue deployments and experimental series at each. Additional short stations along the transect from WHOI to BATS will also be made.

SSSG (Andy Girard) is supplying small "Grey Coastal Winch" with hydraulic power pack (480vac, standard 30 amp plug ) This winch was approved by Al Suchy and Captain Bearse for this operation. Non-Metallic Metering Block also being supplied by SSSG. Small cube refrigerator Program-Provided We will supply 3/16" 'AmSteel' cable and GO-FLO Science Tools: bottles for trace metal-clean sampling (maximum depth = 100 m; maximum load = two 12-liter bottles). We will want to protect the cable from contact with the rail and other metal structures. - We will hand deploy a holey-sock drogue, suspended at 75 m depth or shallower, marked with a high-flier buoy with radio beacon (160.785 MHz) and strobe light. Individual deployments will last a maximum of 36 hrs. - Liquid Nitrogen will be used in the Main Lab (~five 35-liter Dewers) for sample storage. We will need to arrange for delivery of liquid nitrogen dockside, just prior to departure. Hand deployed net tows Deck Incubators - Seawater supply by garden hose needed Lab Incubator - to be secured in Main Lab Shipboard Equipment/Nav: Other Requirements: Night Work Anticipated Electrical Requirements - 3 phase, 208V, 50A electrical supply in Main Lab (for Flow Cytometer) Notes: HazMat list will be supplied prior to cruise. All quantities are anticipated to be small (~ 1 liter or less) except 10% HCl (~20 liters) and liquid nitrogen (~100 liters). All HazMat will be removed and transported back to home institutions at completion of cruise. Navy Clearance Status: Last Modified: 12/13/2006 Check List: Required?
