Summary for Field Activity Number 1993-010-FA

Area of Operations: San Pablo Bay, California, United States, North America, North Pacific

Dates: May 24, 1993 to May 29, 1993

Objectives: Deploy and recover OBSes.

Type of Activity:

Information to be derived:

Summary: Three of the four OBSes were recovered without incident. OBS C-9 confirmed release but could not be found by the recovery party. C-9 was eventually recovered by a tug boat operator on June 2nd. The OBSes worked well in this operation. There were no mechanical or electronic problems. The remote communications capability with the OBS on deck (which is new as of this operation) worked well. In small boat work such as this, the small spheres were a blessing and in fact the work could not have been done with the large spheres. Using a whaler as a deployment and recovery vehicle is marginal. The davit, which held the OBS 40 inches above the rail and 20 inches out, was essential in deploying the OBSes. Work needs to be done on developing navigational and power systems that can work effectively on small boats, particularly since the majority of recent deployments have been small boat operations.
