Description:
Abstract:
This 100-m-resolution sediment thickness data raster for the Offshore of Arcata, 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.
