Online_Linkage: https://doi.org/10.5066/P9EC35PF Description: Abstract: This substrate, geomorphic, and geologic attributed polygon shapefile in the Offshore of Eureka, California, map area is part of USGS Data Series 781 (Golden and Cochrane, 2019). The map area is one of 83 map areas of the California State Waters Map Series. The polygons are derived from multibeam echosounder (MBES) data and derivatives of that data using video-supervised and unsupervised classification. Attributes and attribute values are named following the Coastal and Marine Ecological Classification Standard (CMECS; Federal Geographic Data Committee, 2012) to be useful for ecosystems management. Purpose: To expand geologic mapping to the seafloor within California's State Waters, to update coastal habitat mapping, and to contribute to a uniform regional habitat database. Additionally, to provide a habitat map for the public and Eco-science community to aid in land-use and land-management decisions both onshore and offshore.

Online_Linkage: https://pubs.usgs.gov/mf/2000/2336/ Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Polygons were derived using video supervised classification and unsupervised classification, and attribute values assigned to polygons are based in part on geologic interpretation; the accuracy of the attribute values and of substrate observations from video cannot be quantified. Polygons were visually checked for overshoots, undershoots, duplicate features, polygon closure, and other errors by the lead author and by the GIS technicians who created the digital database. Logical_Consistency_Report: Units are consistent based on an accuracy assessment using observations of substrate in video data. Completeness_Report: Data are complete, in the conversion of rasters with 2-m resolution some small areas were eliminated by filtering to reduce the number of small polygons. The smallest area represented is approximately 0.5 square meters. All geospatial database elements are attributed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Polygons were mapped by numerical classification of 2-meter-resolution backscatter intensity, and derivatives of bathymetry data, and from visual observations of underwater sea floor video. Sea floor video information position accuracies are highly variable, on the order of 10 meters. Horizontal position given is ship position. A towed camera can be on the order of 10 meters distance from the ship during deployment. MBES data have a horizontal accuracy of approximately 2 meters in continental shelf depths. A horizontal accuracy of polygon boundaries cannot be quantified. Lineage: Process_Step: Process_Description: Mosaics of bathymetry and backscatter intensity data for the map area were created from component surveys conducted by Fugro Pelagos Inc. and the California Seafloor Mapping Lab at California State University Monterey Bay. Process_Date: 2023 Process_Step: Process_Description: Seafloor induration was derived from the backscatter intensity and derived ruggedness rasters using the video-supervised method of Cochrane (2008). The CMECS Substrate Induration values are described in Federal Geographic Data Committee (2012). Process_Date: 2023 Process_Step: Process_Description: The seafloor induration raster was combined with a CMECS slope class raster, a bathymetry position index raster and a CMECS depth zone raster resulting in 30 unique classes of seafloor. The raster was filtered to reduce the number of small areas and converted to polygons. The resulting shapefile has a few geoforms that were classified by hand in places where geologic interpretation was used.
