Summary for Field Activity Number 88020

Alternate Leg: ID (F-13-88-NC)

Area of Operations : Point Sal, Northern California, United States, North America, North Pacific

Dates: December 5, 1988 to December 13, 1988

Chief scientist: D.Cacchione, D.Drake
   

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 side-scan survey at project sights R8, PJ1, a,d R9. 2. Deploy 2 surface guard buoys at each sight (R8, PJ1, R9). 3. Deploy 3 subsurface current meter moorings at R8,PJ1, R9. 4. Deploy 2 GEOPROBE tripods at R8 and PJ1. 5. Collect box cores for detailed and sediment analyses. 6. Collect hydrographic and suspended matter samples.
