Rd. West Boothbay Harbor ME 04575 Phone: 207-633-9668 Email: cpilskaln@bigelow.org Cruise Objective: Deployment of 4 oceanographic moorings; few CTD casts Science Activities: Operations Area: 43 degrees 36.3 minutes N; 68 degrees 43.5 minutes W and 43 degrees 30 minutes N; 67 degrees 50 minutes W 150-290 m SSSG Tech: sssg @oceanus.whoi.edu Departure Port: Woods Hole, Massachusetts Agent: Master R/V Oceanus Attn: Scientist's Name c/o WHOI 266 Woods Hole Rd. Woods Hole, MA 02543 Contact: John Dyke tel. (508) 289-3770 fax: (508) 457-2185 email: jdyke@whoi.edu Arrival Port: Woods Hole, Massachusetts Agent: Same as above Installed Scientific 12 kHz Equipment: CTD/Rosette 24X10L Niskins Fume Hood Refrigerator WHOI-Provided Science Mooring Winch Tools: Air Tuggers (2) Program-Provided Science Tools: Shipboard Doppler/GPS Navigation Equipment/Nav: Other Requirements: Loading of mooring gear, sediment traps, etc. will require dock forklift and ship's crane. Load gear on 30th and wind mooring on 31st to mooring winch Notes: Hazardous Material - None necessary/all harardous material (4% buffered formalin & seawater solution) will be deployed in sediment trap sample cups at mooring sites. We'd like to have a discussion of the mooring deployments/plan with the ship's bosun on the day we load, if that's possible. Towed Instrument (DiVa) has been removed from Synopsis due to a component delay. REVISED General deployment plan for Pilskaln moorings, April 1-4, 2005, R/V Oceanus See accompanying mooring schematics and instrument and surface buoy info. Subsurface mooring deployments are all planned for over the stern. **May be necessary, due to buoy height, to deploy large surface buoy over starboard side with crane, leading the mooring wire back around the starboard quarter and through the A-frame to the winch (see below). First site will be the Offshore Penobscot Bay site (43.605 N; 68.725 W), 158 m bottom depth. Mooring with a large surface marker buoy (MSI G2000 with light tower) will be deployed first using crane to place surface buoy over the side. Wire rope will be spooled and deployed through stern block as above followed by a quick release anchor drop. Subsurface trap mooring will be deployed next, using standard anchor-last technique. Quick release used for placing traps and railroad wheel anchor in water. Four-float "packages" can also be deployed using quick release if desired. Wire rope will be spooled onto small deck winch and run thru an A-frame block that can pass the booted terminations. Instruments/float packages will be inserted at terminations on the fan-tail with the assistance of tag lines and A-frame control. Traps (McLane time-series traps) must be kept as vertical as possible during deployment so as not to lose preservative solution from the moderately sealed trap cups. Subsurface mooring will be placed approximately 1 nm from the surface buoy mooring. Following deployment of the moorings, we will move off about 1 nm or so and complete a full-depth CTD cast. Second site will be Jordan Basin site (43.499 N; 67.839 W), 290 m bottom depth. Deployment procedures for the surface and subsurface moorings will be the same as the first site with the following addition: A McLane WTS time-series suspended particle sampler will be deployed 5 m below the surface buoy, followed by the wire rope and railroad wheel anchor. Same cautionary note regarding keeping the traps as vertical as possible during deployment. Full depth CTD cast will be completed after deployments at a safe distance from the moorings. Note: Could the ship please provide a snap block on the A-Frame which will pass the terminations/shakles. Navy Clearance Status: Last Modified: 12/13/2006 Check List: Required?
