Description:

Abstract:

This dataset includes multi-sensor core logger (MSCL) data of sediment cores collected in Cascadia (offshore northern California, Washington, and Oregon) aboard the M/V Bold Horizon September 2022.

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.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Quality control of attribute accuracy was conducted during field data collection and processing workflows.

Logical_Consistency_Report: No formal logical consistency tests were conducted.
Completeness_Report:

This 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.

Positional_Accuracy:

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Core depth values are relative to the top of sediment in the uppermost core section. Coring-induced compaction, if any, was not determined. 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, 3.43-inch diameter barrel, and polybutyrate liner. The JPC trigger arm was set up to collect a trigger core (TC) associated with each JPC (if successful). JPCs 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 segmented into 150 cm (or shorter) sections and split into "working" and "archive" halves in the USGS Pacific Coastal and Marine Science Center core lab. Sediment surfaces were cleaned and smoothed on the "working" halves of split cores. Multi-sensor core logger (MSCL) data were acquired on a Geotek MSCL-S system (www.geotek.co.uk/products/mscl-s/). Each core was scanned through the system and measured simultaneously for density and magnetic susceptibility. Cores with multiple segments are composited into a single comma delimited text CSV file. Total depth in core, depth in an individual core segment, and core segment numbers are provided in the CSV files. File names correspond to the names of each core. For example, ‘2022_653_FA_JPC03.tif’ corresponds to all sections of jumbo piston core ‘JPC03’. A list of MSCL CSV files is included in this data release in the 2022-653-FA_cores.csv file (Hill and others (2025)).

Process_Date: 2022

Process_Step:

Process_Description:

MSCL CSV files were renamed for consistency with other datasets in this data release (Hill and others (2025)).
