Online_Linkage: https://doi.org/10.5066/P9W5RAL4 Description: Abstract: Seismic reflection data and cores were collected in Ozette Lake, Washington, in 2019. Radiocarbon samples were taken from cores in select locations. 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 reflection profiles, chirp seismic reflection profiles, 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. Additional sampling of the split cores included grainsize analysis, X-ray fluorescence (XRF) scanning, and radiocarbon sampling to date stratigraphic ages. Source_Used_Citation_Abbreviation: Dartnell and others, 2024 Process_Date: 20240116 Process_Step: Process_Description: Where suitable material was present, samples from sediment layers of interest were collected and sent to the W.M. Keck Carbon Cycle Accelerator Mass Spectrometer (KCCAMS) Facility or the National Ocean Sciences Accelerator Mass Spectrometry (NOSAMS) Facility for radiocarbon dating.
