Description:

Abstract:

This data release contains 43 chirp sub-bottom profiles that were collected in November of 2014 from the Catalina and Santa Cruz Basins offshore southern California by the U.S. Geological Survey Pacific and Coastal Marine Science Center. Data were collected aboard the University of California’s R/V Robert Gordon Sproul on USGS cruise 2014-645-FA. Chirp profiles were collected to assess earthquake and submarine landslide hazards offshore southern California.

Purpose:

Data were acquired to support USGS geologic hazards projects to aide hazard assessment and shallow geologic structure mapping of southern California’s offshore Catalina, Catalina Ridge, San Clemente, and San Diego Trough Fault Zones. These data were collected to update the USGS Quaternary fault database and shaking hazard models developed by the Working Group on California Earthquake Probabilities. In addition, the survey imaged a large landslide complex in Santa Cruz Basin in order to determine causes and age of seafloor failure. Data collection was funded in part by UC Student Ship Funds. Multichannel seismic-reflection data were collected coincidentally. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.

Attribute_Accuracy_Report: Identified as the best available version

Logical_Consistency_Report:

Chirp sub-bottom data were collected during USGS field activity 2014-645-FA using a hull-mounted Knudsen320B 3.5 kHz digital echosounder. Quality control was conducted during the collection process. Note some lines contain only a few traces.

Completeness_Report:

Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.

Positional_Accuracy:
