CHIRP system (Edgetech SB 512i FSSB chirp sub-bottom profiler) - tow the chirp fish just below the keel on the Oceanus to get the instrument into quiet water for profiling. Survey area Water depths are 30 to 100 M. Plan A is to use 9/16" trawl wire as down line and wire tie conducting cable to it. It would go into the water in the evening and then recover in the morning. Plan B is to use the ship's Knudsen system for profiling if chirp fish not functional. Minor coring to determine locations for tripods. (Box core or Van Veen Grab) Surveying Eyeball to be lowered on .322 to study grain size of ocean floor for tripod placement. 100 meter conducting cable to be hand attached to .322 wire via snap clips. Eyeball softly touches bottom. Blocks needed from vessel - Block for 9/16" trawl wire or snatch block on crane for deployments. Small-Boat Transfer Date: 1 Oct / 1000 hr. Location: Port Transfers: 12 off, 10 on, 2 remain Leg 3 Dates: 1 Oct - 8 Oct General Work: box, kasten and piston coring - 24 hour operations Study Area: western Gulf of Lions, 50-500 m; eastern Gulf of Lions, near mouth of Rhone Participants (12): UW, 2 scientists, Chuck Nittrouer (chief scientist), coring TAMU, 2 scientists, Beth Mullenbach (leader), coring ISMAR (Italian), 1 scientist, Stefano Miserocchi, coring UCSC/AOA, 2 scientists, Dan Orange (leader), coring USGS, 2 scientists, Homa Lee (leader), coring ULaval (Canadian), 2 scientists, Jacques Locat (leader), coring UBarcelona (Spanish), 1 scientist, Joan Fabres, coring ---- Specifics - 24 hour coring operations planned Box Core and Kasten Core will use 9/16 trawl wire. Ewing Piston Corer requires a 25 ft. 1/2" leader clamped on 9/16" trawl wire. This is a lightweight piston corer using 10 or 20 ft lengths of 3" PVC pipe. Core Logger and X-Ray machine used aboard in main lab Blocks needed from vessel - Will block used for 9/16" wire have big enough throat for 9/16" wire and 1/2" leader clamped together? Small-Boat Transfer Date: 8 Oct / 1000 hr. Location: Port Transfers: 11 off, 12 on, 1 remains Leg 4 Dates: 8 Oct - 15 Oct General Work: instrument deployments (permanent and temporary), water-column and seabed (Bothner corer) sampling Study Area: western Gulf of Lions, 10-100 m Participants (13): OSU, 3 scientists, Rob Wheatcroft (chief scientist), coring, instrument deployment (permanent) Dalhousie (Canadian), 1 scientist, Paul Hill, coring, instrument deployment (temporary) BIO (Canadian), 2 scientists, Tim Milligan (leader), coring, instrument deployment (temporary) UVa, 2 scientists, Pat Wiberg (leader), coring ISMAR (Italian), 1 scientist, Stefano Miserocchi, coring BC, 3 scientists, Gail Kineke (leader), instrument deployment (permanent), water sampling UPerpignan (French), 1 scientist, Xavier Durrieu de Madron, water sampling ---- Mostly shallow water operations (27-100 meters water depth) Coring and instruments deployments during day, "Gafanhota" casts from hydroboom at night. CTD casts to collect near bottom (~5 meters) water. CTD data to be collected as backup. Deploy - (at 27meter site) - Profiling CTD and ARP Tripod (1,200 lbs) using ship's crane Deploy/Recover - INSSECT (~450 lbs) deployed for 36-48 hours then recovered Casts- Slow Corer(Bothner corer)(12 per day)(1,100 lbs, 11 ft. tall), ship's CTD for water collection (10 casts expected), "Gafanhota" casts (~100-150 lb CTD instrument which touches down on bottom) Blocks needed from vessel - Snatch Block on crane boom for deployments. Quick release for deployments from crane CTD block in normal place for CTD casts. Special Needs - "Gafanhota" casts will be from the 0.322 wire switching from the CTD to the "Gafanhota" Pre-Cruise Demob in Port Dates: 15-16 Oct Primary Work: Packing and removal of UW cargo container, Packing of another rented cargo container, stowage of some gear in berthing van (Lee and Locat should complete this at end of Leg 2) Participants: All Leg 3 participants and Chuck Nittrouer ------------------------------------------------------------------------------------------------------------------------------------------------------------- Tripod/Instrument Deployment Methods 1. When the instrument is on the bottom or within a meter of the bottom, a release command is sent. As soon as the release is completed the glass ball (hardhat) clears the release and lowering line away from the instrument bringing the release to the surface for recovery. We have had great success with this method on the Oceanus. 2. Slip line method.(See Diagrams) . It can be accomplished but the Bosun suggests that an obtuse angle for the slip line be used to make sure the slip line does not twist. This would mean having the tied off end at the bow and the slipped end coming over the side at the stern. It also requires the package to be lowered to below the keel before triggering the quick release on the crane. Navy Clearance Status: Last Modified: 12/13/2006 Check List: Required?
