Objectives: This cruise was conducted as a part of the sediment transport component of the MMS California OCS Phase II Monitoring Program. Data were successfully collected during the spring/summer of 1987. This cruise was designed to obtain data during the winter season. The specific objectives were: 1. conduct a sidescan survey at project sites R8, PJ1, and R9; 2. deploy 2 surface guard buoys at each site (R8, PJ1, and R9); 3. deploy 3 subsurface current meter moorings at R8, PJ1, and R9; 4. deploy 2 GEOPROBE tripods at R8 and PJ1; 5. collect box cores for detailed sediment analyses; and 6. collect hydrographic and suspended matter samples.

Type of Activity: Sampling; Mooring work; Seismic profiling;

Information to be derived: Time series data; Samples and chemical analysis; Grain size analysis; Suspended sediment concentrations; Sea floor map;

Summary: Moorings deployed: 6 (#327, 328, 329, 330, 331, and 332, recovered FA 89004 FARNELLA Feb. 21-28, 1989). CTD stations: 13; Sidescan sonar: 48 km; Box cores: 6 (processed shipboard by WHOI for E. Crycelius, Battelle); Gravity core: 1; Water samples: 33.
