Summary of Field Work: |
We will deploy five ocean-bottom seismometers approximately 140km northwest of San Diego, CA for four months. We request four days of ship time, two days for a deployment and two days for a recovery, during the summer of 2018. The proposed research serves two purposes: 1) collect crucial broadband data for in-situ calibrations of the SIO differential pressure gauges (DPGs), and 2) assess local seismicity on the San Clemente Fault. |
|
Summary of Facility Requirements: |
We will deploy five ocean-bottom seismometer (OBS) packages furnished by the ocean-bottom seismometer instrument pool (OBSIP) for four months. The R/V Sproul has adequate storage space, A-frame, deck space, and equipment to facilitate this study. We may also use the Knudsen 3260 3.5 kHz chirp system currently installed on the R/V Robert Gordon Sproul for an echo-sounding survey. |
|
Summary of other requirements and comments: |
This proposal is pending funding approval from the UC Ship Funds program, and will support graduate research, data collection, and instrumentation. |

Description of Repeating cruise requirements: |
We will be deploying five instruments for four months. We request one two-day cruise for the deployment and one two-day cruise for recovery. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Our primary constraint is the availability of the ocean-bottom seismometers. We have secured the necessary instruments for a four month period beginning in June 2018. |

Explanation of Science Party Requirements and Technician Requirements |
The science party will consist of the PI (Adrian Doran), the co-PI (Gabi Laske), two engineers from the SIO OBS group, and two students from UCSD. Only one technician should be required as each cruise will include approximately 18 hours of transit time and 12 hours of work. |
