Dataset includes both raw and processed chirp data. 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.

Browse_Graphic_File_Type: JPG Native_Data_Set_Environment: Field seismic data was collected with EdgeTech Discover acquisition software and processed using Shearwater Reveal (v. 5.1) on a CentOS Linux 7 operating system. Seismic tracklines were processed using ArcGIS Pro (v. 2.9.1) on a Windows 10 operating system. 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: All SEG-Y and navigation data were derived from the same instruments and processing workflows. 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. Data release will be updated as additional data is processed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: A Hemisphere V110 GPS system was used for obtaining navigation data during the cruise with a stated accuracy of 0.6 meters (95 percent confidence). Lineage: Process_Step: Process_Description: Field seismic data collection: Seismic data was collected during USGS field activity 2019-622-FA using an EdgeTech SB-512 CHIRP sub-bottom profiler and Discover seismic acquisition software. Field data were collected in JSF and SEG-Y formats. Navigation data was collected simultaneously with a Hemisphere V110 GPS and saved into the seismic headers during acquisition. Process_Date: 20191024 Process_Step: Process_Description: The following processing flow was carried out in Shearwater Reveal (v. 5.1) to process field data output to SEG-Y files: (1) Field-collected SEG-Y files were imported to Shearwater Reveal and navigation was converted to WGS 1984 UTM Zone 10 North. These coordinates are populated in the seismic trace headers in bytes 73 and 77. SEG-Y files were added to the data zip file (2019-622-FA.seismic.chirp.zip).
