Description:
Abstract:
This 100-m-resolution sediment thickness data raster for the Offshore of Eureka, California, map area is part of USGS Data Series 781 (Golden and Cochrane, 2019). Seismic data were collected by the USGS in 2009 using a mini-sparker seismic systems installed on the Humboldt State University R/V Coral Sea. The data were processed by the USGS into segy format files. The data are available as a georeferenced TIFF image.
Purpose:
The surveys were conducted to map geology and benthic habitat as part of the USGS California Seafloor Mapping Program (CSMP), a collaboration with California State University Monterey Bay (CSUMB) and the National Oceanic and Atmospheric Administration (NOAA). Partial funding was provided by the California Ocean Protection Council. These data are intended to provide regional geospatial information in California State waters for offshore resource and ecosystem management. These data are also intended for science researchers, students, policy makers, and the general public. These data can be used with geographic information systems or other software to help identify geomorphologic features and surficial lithology. These data are not intended to be used for navigation.
Supplemental_Information:
Additional information about the USGS field activity from which some of these data were derived is available online at:

Attribute_Accuracy:
Attribute_Accuracy_Report: Not applicable for raster data.
Logical_Consistency_Report: No formal logical accuracy tests were conducted.
Completeness_Report:
Dataset is considered complete for the area mapped with MBES data.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The sparker position may vary as much as 20 m from the navigation reference on the vessel.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Estimated to be approximately 1 m, along the track lines where data is well constrained, but may be much greater in areas between tracklines where interpolation occurred, or data processing swell correction was inaccurate.
Lineage:
Process_Step:
Process_Description:
Water bottom (seabed) and depth to an interpreted base of the Last Glacial Maximum (LGM) horizons were digitized from seismic-reflection data using Kingdom Suite software. The difference between the two horizons was exported from Kingdom Suite for every shot point as XY coordinates (UTM Zone 10) and two-way travel time (TWT). The thickness was determined by applying a sound velocity to the TWT of 1,500 m/sec in water and 1,600 m/sec velocity in sediment, resulting in sediment thickness values.
Process_Date: 2023
Process_Step:
Process_Description:
XY locations and sediment thickness values Z were imported to ArcGIS format as points and interpolated to a surface using the Trend tool.
