+--------------------------------------------------------------------------+ | ATLANTIS CRUISE SYNOPSIS | +--------------------------------------------------------------------------+ Voyage - Leg: AT 13 Voyage Dates: 18-31 January 2006 Chief Sci(s): Terry Joyce (Toole) Address: WHOI 266 Woods Hole Rd MS #21 Woods Hole, MA 02543 Phone: 508-289-2530 Email: tjoyce @whoi.edu Cruise Objective: Science Activities: The work plan is as follows: The vessel will loaded 16 & 17 January, depart from WHOI 18 January, and make way for a target location just south of the Gulf Stream, at a longitude near 70oW. After making our first CTD cast, we will then prepare to deploy the compound spar, "S", the largest single deck item on the vessel. After deployment, our efforts will be to zig-zag across the Gulf Stream, following the compound spar as it drifts downstream, making CTDs, radiosondes, and launching floats & drifters as required. After ~. 10 days, we would recover the compound spar, occupy a CTD station at the location of the surface meteorological buoy "F", presently being deployed on Oceanus (target location is: 38.5N, 65W ), and return to port on 31 January. The actual cruise scenario will depend on the location & structure of the Gulf Stream during the cruise, as given by daily satellite data. Major activity categories: - Occupy ~ 90 CTD stations to 1000m depth (Joyce, Talley, Lozier) - Deploy ~ 20-25 Radiosondes, shipboard air-sea fluxes from mast (Edson) - Deploy & recover AirSea Interaction Spar (Edson) and tethered moored profiler (Toole) - Deploy subsurface bobbing, acoustic floats (Fratantoni) - Deploy surface `holey sock' drifters (Lumpkin) - ADCP profiling using 75 kHz Ocean Surveyor (Joyce) - Replace sensors on CLIMODE Mooring by small boat towards end of cruise as weather conditions allow (Bahr) Operations Area: NA6 34-40DEGN, 72-62DEGW 1000m typical, 3000m max.

(508) 289-2277 fax: (508) 457-2185 email: ecaporelli @whoi.edu Arrival Port: Woods Hole, MA Agent: Same As Above Installed Scientific ADCP - 75kHz - Mission Critical Equipment: CTD/Rossette - Dual T/C, single Oxy. - WHOI is a backup Salinometer IMET Sensors - All - with mounted backup sensor - Critical Seabeam Thermosalinograph Fume Hood Uncontaminated Seawater for PCO2 system WHOI-Provided Science Tools: Program-Provided Science Tools: Shipboard Doppler/GPS Navigation Equipment/Nav: Small Boat Operations Other Requirements: Night Work Anticipated Atlantis HiSeasNet is mission critical to this cruise to provide Gulfstream satellite image guidance. Shipboard 75kHz Ocean Surveyor ADCP is mission critical to this cruise. IMET sensors are mission critical to this cruise. Backup windspeed and direction are required and mounted on IMET mast CTD: SIO/ODF will provide primary rosette/CTD system, Autosals, oxygen titration and nutrient analysis. Backup CTD: WHOI 24x4L rosette/CTD will be backup system. LADCP: WHOI will provide RDI dual workhorse LADCP for use on WHOI rosette as backup. Notes: Hazardous materials may be used by the SIO/ODF groups for oxygen titration and nutrient analysis. They will provide the inventory for these. All hazardous materials will be removed from the ship upon return to WHOI at the end of the cruise. PCO2 system run by Nick Bates (BBSR) will require the Uncontaminated Seawater system Jonathon Ware (WHOI) will need to mount sensor on IMET Tower - waiting for more information Science party would like to store floats and Mooring gear in the ALVIN and ROV hangers SPAR BUOY and MMP MOORING: Need 2 cranes and operators for deployment of Spar Buoy and Cable (both cranes at the same time) Spar buoy (ASIS) will be deployed and recovered on this cruise. Buoy will be connected by long floating tether to small surface expression of a drifting MMP mooring (FILIS). Buoy will be deployed first from portside, then MMP mooring will be deployed from starboard aft. This buoy weighs 6,000 in air and is 15 meters long. Buoy is very heavily instrumented with delicate equipment and requires special handling over the side to assure upright deployment. * It is STRONGLY urged that a test deployment of this Spar buoy (without MMP) be done off the Atlantis portside into Great Harbor while the ship is at dock prior to the cruise. This is to be certain that all logistics are worked out prior to the cruise and that crew and deck team are familiar in good conditions with the operation.. A test is tentatively scheduled for the 17 January (estimated to take 2 hours) Buoy will be loaded aboard and secured along bulwarks aft portside. Method of deployment and recovery will require use of portside crane with two lifting points and two quick release hooks. Three airtuggers on pedestals with sufficient line will be required for deployment and recovery. * Ship is requested to provide sufficient compressed air supply for operating three tuggers at full load simultaneously. WHOI will provide TSE winch which will be used for deployment and recovery of drifting MMP mooring. TSE winch will be located on aft starboard side, aft of stbd crane. TSE winch weighs 7,000 lbs. * Ship asked for removal of starboard aft quarter bulwarks during MMP deployment and recovery. * Ship is asked to provide power for TSE winch at this location. * Ship is asked to provide inflatable boat for possible use during deployment and recovery if problems develop with buoy/mooring. Request use of the inflatable used for Alvin work. This boat can be kept in the normal position starboard of the Alvin starboard hangar door. Three wire baskets containing the tether and related equipment will be located on starboard deck aft of the Alvin hangar. Will Ostrom (ext 3288, wostrom @whoi.edu) will provide details on the deck plan. - (1/9/06) Bob Weller wants the Atlantis to stop by his CLIMODE surface moooring (CLIMODE surface mooring (F) was launched at 38 19.25 and -64 46.34) if the opportunity presents itself on our AT13 cruise, and deploy a small boat with Frank Bahr with some replacement sensors. Estimated time on location is 2 hrs, with 1/2 hr. needed on the buoy itself. This will occur near the end of our cruise and only under favorable weather conditions as determined by the Master of the Atlantis Navy Clearance Status: Last Modified: 01/19/2006 Check List: Required?
