The map will be updated as needed. The California Seafloor Mapping Program is a cooperative partnership between state, federal agencies, universities, and industry to create a comprehensive coastal/marine geologic and habitat base map series for all of California's state waters. The U.S. Geological Survey, Pacific Coastal and Marine Science Center maintains the California Seafloor Mapping Program website with this page dedicated to showing the extent of mapping and ground-truth progress. 20080601 201303011 ground condition In work As needed -124.50000 -117.00000 41.70000 33.50000 General Marine Geology Multibeam Geology Habitat Bathymetry Backscatter Sea Floor Ocean Floor Topography U.S. Geological Survey USGS Coastal and Marine Geology Program CMGP ISO 19115 Topic Category elevation imageryBaseMapsEarthCover oceans Global Change Master Directory (GCMD) oceans > bathymetry/seafloor topography > bathymetry Geographic Names Information System (GNIS) Bodega Bay California Catalina Island Channel Islands Crescent City Farallon Islands Fort Bragg Humboldt Bay Long Beach Harbor) Los Angeles Harbor Monterey Bay Morro Bay Pigeon Point Point Arena Point Conception Point Mugu Point Reyes San Clemente Island San Diego San Francisco Bay Santa Barbara Santa Barbara Island Santa Catalina Island None Please recognize the U.S. Geological Survey (USGS).

Therefore, no assessment of the accuracy of the identification of entities and assignment of attribute values in the data set and a description of the tests used are provided. No explanation of the fidelity of relationships in the data set and tests used are provided. Data will be updated as needed. No additional information about omissions, selection criteria, generalization, definitions used, and other rules used to derive the data set are provided. No explanation of the accuracy of the horizontal coordinate measurements and a description of the tests used are provided. No explanation of the accuracy of the vertical coordinate measurements and a description of the tests used are provided. ESRI shapefiles were created for California Seafloor Mapping Program map sheets. The shapefiles were converted into Google map files and added to the Google map.
