Online_Linkage: https://doi.org/10.5066/P1VQIJ2Q Description: Abstract: This dataset presents core information such as core IDs, section numbers, lengths, depth intervals, and locations from sediment cores collected in Cascadia (offshore northern California, Oregon, and Washington) aboard the M/V Bold Horizon September 2022. An inventory of core section computed tomography (CT), multi-sensor core logger (MSCL), and photograph scan files available in this data release are listed here. Purpose: As part of a multi-year project focused on characterizing offshore marine geohazards (tsunamis, earthquakes, and landslides), the U.S. Geological Survey (USGS) Coastal and Marine Hazards and Resources Program is conducting research offshore northern California, Oregon, and Washington to gain a better understanding of the geologic hazards of the region, improve risk assessments for local communities and critical infrastructure, and to provide data for future research on regional tectonic, sedimentary, and geomorphic evolution. Sediment cores were collected to enable a detailed investigation of Cascadia's geologic history and ongoing activity.

Logical_Consistency_Report: No formal logical consistency tests were conducted. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Users are advised to carefully read the rest of the metadata record for additional details. Some cells are intentionally left blank if there was no recovery of the core or other issues with core quality. These issues are noted in the ‘notes’ column. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: A Hemisphere V110 GPS system was used to obtain latitude and longitude point locations during the field activity, with a stated accuracy of 0.6 meters (95 percent confidence). Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Water depth values at core locations were estimated from multibeam bathymetric data (Dartnell and others (2021), or Dartnell and others (2023), or Ryan and others (2009)). No formal vertical accuracy tests were conducted. Lineage: Process_Step: Process_Description: Cores were collected aboard MV Bold Horizon using a U.S. Geological Survey (USGS) jumbo piston corer (JPC) on cruise 2022-653-FA. The JPC system consisted of a 2500-lb head weight, 8.71-centimeter diameter barrel, and polybutyrate liner. The JPC trigger arm was set up to collect a trigger core (TC) associated with each JPC (if successful). Gravity cores (GC) were collected using the same JPC system (minus trigger and TC) in two localities. JPCs and GCs were extruded and sectioned at sea. The cores were then transported back to the USGS Pacific Coastal and Marine Science Center. Process_Date: 2022 Process_Step: Process_Description: Cores were scanned, split, and sampled at the USGS Pacific Coastal and Marine Science Center core lab in Santa Cruz, CA. Information about the cores were combined into a comma-delimited text value document (2022-653-FA_cores.csv). Process_Date: 2022 Process_Step: Process_Description: CT TIFF images, line scan photo TIFF images, and MSCL CSV files were renamed for consistency with other datasets in this data release (Hill and others (2025)).
