Summary for Field Activity Number 87044

Area of Operations : southern California

Dates: November 1, 1987 to November 3, 1987

Chief scientist:
   

Objectives: The objective of this short cruise was to attempt to locate and recover a current mooring deployed at 34 degrees 54.7 N, 120 degrees 59.5 W in about 400 m of water off Pt. Sal, CA. The mooring, containing 3 EG&G vector averaging current meters, was deployed as part of the California Montitoring Program (CAMP) in May 1987 and was to be recovered in July 1987. No attempt could be made to recover or interrogate the mooring on the July cruise because of heavy weather and ship failures. Recovery was re-scheduled for September. On this cruise, the mooring did not respond to any acoustic commands; it was assumed that either the release had failed or that the mooring was dragged away fishing activity. Because of the equipment and importance of the data, an additional acoustic search using the release gear, a side-scan sonar search with an EG&G 50 kHz system, and a search utilizing a remotely operated vehicle(ROV) were planned to locate the lost mooring.
