Summary of Field Work: |
We plan on conducting two targeted multi resolution seismic surveys along the San Clemente Fault using CSULB’s sparker-Multi-Channel Seismic (MCS) system as well as the Driscoll Neotectonics Lab’s Compressed High Intensity Radar Pulse (CHIRP) instrument. Once on station (north or south site, contingent on US Navy Base San Clemente Island range schedule) the MCS system, consisting of a seismic source (Sparker) and receiver (16 Channel Geo-Eel digital hydrophone streamer) will be deployed, enabling regional scale data to be collected. The method of deployment and recovery for the MCS system will be either A-frame, 9/16 trawl wire or by hand; to be determined jointly between ResTech(s) and PI and ultimately contingent on sea state. Bureau of Ocean Energy Management mitigation measures will be employed to minimize the impact of seismic surveys on marine mammals. Once the MCS survey is complete the MCS system will be recovered and secured on deck. Following the MCS survey the CHIRP instrument will be deployed via the shipboard A-frame, 9/16 steal cable and winch, and towed at a yet TBD depth where the signal to noise ratio is optimal for data collection. Once the targeted survey is complete, the CHIRP will be recovered and secured for transit to the second site. At second site seismic instruments will be deployed in the same order as first sites, deployment and recovery methods will be dependent on sea state. |
