Other ID: OC130

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Data Type(s): Location-Elevation: Navigation, Sampling: Biology, Sampling: Geology, Sonar: Single Beam, Time Series: Mooring (physical oceanography)

Scientific Purpose/Goals: 1. Recover 2 subsurface moorings and 1 bottom tripod system deployed in Lydonia Canyon. This recovery completed the 2-year field measurement program in Lydonia and Oceanographer Canyons. 2. Recover 3 sediment-trap moorings deployed near Mobil Block 312. This array was designed to measure the resuspension and transport of drill muds discharged during drilling. 3. Deploy 5 subsurface moorings on the continental slope. This array initiates a large study of currents and sediment movement along the outer shelf, continental slope, and upper rise. 4. Conduct a detailed hydrographic survey around Lydonia and Oceanographer Canyons and along the continental slope in support of objectives 1 and 3. 5. Obtain hydrostatically damped cores in the Mud Patch, Lydonia Canyon, and around Lease Block 312 to document the vertical distribution of drill muds in surficial sediments. 6. Obtain surface grab samples around Lydonia and Oceanographer Canyons to refine surface-sediment texture map. 7. Recover 5 surface marker buoys deployed to mark instrument sites.
