Other ID: EW9415,LARSE
Status: Completed
Organization(s): USGS, Pacific Coastal and Marine Science Center
Funding Program(s): Los Angeles Region Seismic Experiment (LARSE) (MU161)
Principal Investigator(s): Tom Brocher
Affiliate Investigator(s):
Information Specialist(s): Ray Sliter
Data Type(s): Seismics: Air Gun / Water Gun, Seismics: Multichannel, Sonar: Single Beam, Seismics: Sub Bottom Profiler
Scientific Purpose/Goals: Study deep seismic structure of Transverse Ranges, Los Angeles Basin, and Inner Continental Borderland
Vehicle(s):
Start Port/Location:
End Port/Location: 13, 1994 - Long Beach, CA and 21, 1994 - San Diego, CA
Start Date: 1994-10-13
End Date: 1994-10-21
Equipment Used: 24channel, airgun, 3.5khz
Information to be Derived: Multi-channel images of southwest edge of Los Angeles Basin show basin sediments truncated at large northeast dipping system of structures that separate them from Catalina Schist basement to the southwest. Moho beneath the Inner Continental Borderland is flat at about 14 km depth and it dips northeast to 20 km beneath Los Angeles Basin.
Summary of Activity and Data Gathered: Data were gathered along three long profiles, all of which extended both onshore and offshore. One extended from the Mojave Desert to San Clemente Island, a second from Soledad region to the region west of San Clemente Isand, and a third from Orange County to the area offshore south of the northern Channel Islands.
