Description:

Abstract:

This data release contains 25 multichannel minisparker seismic reflection (MCS) profiles that were collected in February of 2016 from the Catalina Basin offshore southern California by the U.S. Geological Survey Pacific and Coastal Marine Science Center in cooperation with the University of Washington. Data were collected aboard the University of Washington’s R/V Thomas G. Thompson on USGS cruise 2016-616-FA. MCS profiles were collected to image the Catalina and San Clemente fault systems as well as the San Gabriel Canyon and Channel system.

Purpose:

Data were acquired to support USGS geologic hazards projects to aide hazard assessment of southern California’s offshore Catalina and San Clemente fault zones. Data collection was funded by UW Student Ship Funds. Chirp sub-bottom data, high-resolution multibeam bathymetry, and backscatter data (Dartnell and others, 2017) were collected coincidentally. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.

Supplemental_Information:

Additional information about the field activities from which these data were derived is available online at:

Process_Description:

Seismic-reflection profiles were acquired using a 1.2kJ Joule minisparker source and recorded with a 150 meter, 24-channel Geometrics MicroEel analog seismic streamer with 6.25m group spacing.

Process_Date: 20160226

Process_Step:

Process_Description:

MCS profiles were processed using SIOSEIS and Echos seismic software. SIOSEIS processing included conversion from SEGD to SEGY and geometry. Echos processing included NMO, spherical divergence gain, three trace runmix, 80-600Hz bandpass filter, two static corrections to adjust for swell along the streamer, spiking deconvolution, stack, water column mute, trace balance, finite difference time migration, AGC, water column mute and a second 3 trace runmix. Navigation was converted to UTM zone 11N and smoothed over 50m using MatLab.
