Cruise Funding Source:

Contract:

Type of Activity:

Mooring work
side-scan sonar survey
collect box cores

Objectives:

This cruise was conducted as part of the sediment transport project of the California OCS Phase II Monitoring Program. The objectives of the cruise were to: 1.) Conduct a side-scan sonar survey at three locations (in the vicinity of regional stations R8, PJ1, and R9, stations A, B and C, respectively); 2.) Deploy subsurface current moorings at these three sites; 3.) Deploy GEOPROBES at stations A and B; 4.) Collect box cores for detailed sediment analysis; 5.) Conduct a hydrographic and suspended matter survey on three cross-slope transects.

Information to be derived:

Time series data
Samples and Chemical Analysis
Grain size analysis
Suspended Sediment Concentrations
