Online_Linkage: https://doi.org/10.5066/P9W5RAL4 Description: Abstract: Seismic-reflection data and cores were collected in Ozette Lake, Washington, from 2019 to 2021. These data were used to investigate 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 Ozette Lake, 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.

Source_Citation_Abbreviation: Dartnell and others, 2024 Source_Contribution: High resolution bathymetry data Process_Step: Process_Description: Sediment cores were collected throughout Ozette Lake, WA during USGS field activity 2019-622-FA and 2021-641-FA using either a vibracorer (VC- labeled core ID), a gravity corer (GC- labeled core ID), or a mini-hammer corer (BC- labeled core ID). Water depths were derived from high resolution bathymetry (Dartnell and others, 2024). Sediment cores were sent to USGS Pacific Coastal and Marine Science Center (PCMSC) for processing and archiving. At PCMSC, cores 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 JPEG using imagemagick command line tools.
