Geophysical and core sample data collected offshore central California, during field activity 2019-651-FA (ver 2.0, August 2023)

This dataset includes sub-bottom seismic and sediment core data collected during USGS field activity 2019-651-FA. Data were collected aboard the M/V Bold Horizon in October 2019 offshore central California in the vicinity of Morro Bay. Sub-bottom data include multichannel sparker and CHIRP seismic in SEG-Y format with associated navigation tracklines. Core data include photo and computed tomography (CT) scans, and various mineralogical, radiometric, and other sampling data. Users are advised to read the metadata documents thoroughly for information on each data type provided. These data were collected to further our understanding of geologic hazards near the Hosgri Fault, improve risk assessments for local communities and critical infrastructure, and to provide data for future research on regional tectonic, sedimentary, and geomorphic evolution of coastal California. This work was funded through a Cooperative Research and Development Agreement (CRADA) between the USGS and Pacific Gas and Electric Corporation.
