This dataset includes photographs of sediment cores collected offshore central California in the vicinity of Morro Bay. These data were collected aboard the M/V Bold Horizon in October 2019 for use in regional hazard assessments relating to the Hosgri Fault.
Identification of fault-related submarine hazards is a primary mission of the USGS Coastal and Marine Hazards and Resources Program. The Hosgri Fault is a submarine fault system that likely poses the greatest submarine earthquake threat in the central California region. To gain a better understanding of this fault system, the USGS collected sparker multichannel seismic, CHIRP seismic, and sediment cores to enable a detailed investigation of its geologic history and ongoing activity. These data are intended 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.

USGS PCMSC Marine Facility personnel Rachel Marcuson, Jenny McKee, Cordell Johnson, and Dan Powers led vibracore collection operations.
Core photographs were taken on a Geotek multi-sensor core logger (MSCL) system.
Quality control of attribute accuracy was conducted during field data collection and processing workflows.
No formal logical consistency tests were conducted.
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.
Cores were collected aboard the M/V Bold Horizon using a Rossfelder P-5 vibracorer on U.S. Geological Survey cruise 2019-651-FA. The cores were transported back to the USGS Pacific Coastal and Marine Science Center core lab where they were split and photographed using a Geotek multi-sensor core logger (MSCL) system. Cores over 1.5 m in length were split into multiple sections to permit scanning. Images from the scanner had ruler scales appended using the Geotek Add Ruler v 1.4 software and then multi-section core images were recombined and converted to JPG using imagemagick command line tools.

Core photographs are provided in a zip archive (2019-651-FA_cores_photos.zip) accompanied by CSDGM FGDC compliant metadata. Note that rulers appended to images are provided for scale only and do not necessarily correlate with length measurements in the tabular data provided with this data release (for example the length along a core where a radiocarbon sample was collected). Users are advised to use the rulers as a scale to make length measurements along the core.
Unless otherwise stated, all data, metadata and related materials are considered to satisfy the quality standards relative to the purpose for which the data were collected. Although these data and associated metadata have been reviewed for accuracy and completeness and approved for release by the U.S. Geological Survey (USGS), no warranty expressed or implied is made regarding the display or utility of the data on any other system or for general or scientific purposes, nor shall the act of distribution constitute any such warranty.
