Description:

Abstract:

This dataset includes multi-sensor core logger (MSCL) data from sediment cores collected in Lake Ozette, Washington. The sediment cores were collected during USGS field activities 2019-622-FA and 2021-641-FA for investigating submarine landslide deposits triggered by large Cascadia Subduction Zone earthquakes.

Purpose:

Identification of fault-related submarine hazards is a primary mission of the USGS Coastal and Marine Geology Program. In the US Pacific Northwest region, the greatest earthquake and tsunami threat is posed by the Cascadia Subduction Zone. From 2019-2021 the USGS carried out a detailed field investigation of earthquake-triggered landslide deposits in Lake Ozette, WA, to reconstruct the timing and severity of large subduction zone earthquakes in northern Cascadia. Field data collected as part of this investigation include boomer single-channel seismic, chirp seismic, and sediment cores. These data are intended to further our understanding of geologic hazards relating to the Cascadia Subduction Zone, improve risk assessments for local communities and critical infrastructure, and to provide data for future research on regional tectonic and sedimentary history of northern Cascadia.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Quality control of attribute accuracy was conducted during field data collection, processing workflows, and in compilation of this data release.

Logical_Consistency_Report:

No formal logical consistency tests were conducted. MSCL data values are sometimes inaccurate where there is air within the core section (usually near the start and end of core sections) due to the multi-sensor core logger’s calibration to expect sediment. This may result in nonsensical data values such as negative densities and P-wave velocities.

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. No MSCL data are available for vibracores VC-16 and VC-34.

Lineage:

Process_Step:

Process_Description:

Vibracores (VC- labeled core IDs) were collected using a Rossfelder P-5 vibracorer during USGS field activity 2019-622-FA and bob cores (BC- or -BC labeled core IDs) were collected using a mini-hammer corer during USGS field activity 2021-641-FA. The cores were transported back to the USGS Pacific Coastal and Marine Science Center core lab for splitting and archiving and subsequent analyses.

Process_Date: 2021

Process_Step:

Process_Description:

Multi-sensor core logger (MSCL) data were acquired on a Geotek MSCL-S system (https://www.geotek.co.uk/products/mscl-s/). Each core was scanned through the system which records core thickness, p-wave amplitude, p-wave velocity, density, magnetic susceptibility, and acoustic impedance. Users are advised to review the data carefully as measurement intervals and measurements taken vary among cores. No data values are noted by ‘n.d.’ values and often occur near the start and end of core sections.
