The raster data file is included in \"Bathymetry_OffshoreBolinas.zip,\" which is accessible from https://pubs.usgs.gov/ds/781/OffshoreBolinas/data_catalog_OffshoreBolinas.html. These data accompany the pamphlet and map sheets of Cochrane, G.R., Dartnell, P., Johnson, S.Y., Greene, H.G., Erdey, M.D., Golden, N.E., Hartwell, S.R., Manson, M.W., Sliter, R.W., Endris, C.A., Watt, J.T., Ross, S.L., Kvitek, R.G., Phillips, E.L., Bruns, T.R., and Chin, J.L. (G.R. Cochrane and S.A. Cochran, eds.), 2015, California State Waters Map Series \u2014 Offshore of Bolinas, California: U.S. Geological Survey Open-File Report 2015\u20131135, pamphlet 36 p., 10 sheets, https://doi.org/10.3133/ofr20151135.\nThe bathymetry map of Offshore Bolinas, California, was generated from bathymetry data collected by California State University, Monterey Bay (CSUMB), by Fugro Pelagos, and by Moss Landing Marine Laboratory (MLML). Mapping was completed between 2004 and 2010, using a combination of 200-kHz and 400-kHz Reson 7125, and 244-kHz Reson 8101 multibeam echosounders, as well as 468-kHz SEA SWATHPlus and 250-kHz GeoSwath interferometric systems. Moss Landing Marine Laboratory mapped the nearshore region north of Bolinas in 2004 prior to the California Seafloor Mapping Program (CSMP). The nearshore region from south of Bolinas Lagoon to Stinson Beach was mapped by Fugro Pelagos in 2009 for a project outside of the CSMP and only bathymetry data were collected. These mapping missions combined to collect bathymetry from about the 10-m isobath to beyond the 3-nautical-mile limit of California's State Waters.\nNOTE: the horizontal datum of the bathymetry data (NAD83) differs from the horizontal datum of other layers in this data series (WGS84). Some bathymetry grids within this map were projected horizontally from WGS84 to NAD83 using ESRI tools to be more consistent with the vertical reference of the North American Vertical Datum of 1988 (NAVD88). These data are not intended for navigational purposes.", "distribution": [{"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.1512f147-5de9-4400-96de-be10635debbe.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "accessURL": "https://pubs.usgs.gov/ds/781/OffshoreBolinas/data_catalog_OffshoreBolinas.html", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_1512f147-5de9-4400-96de-be10635debbe", "keyword": ["sonar methods", "distributions", "imageryBaseMapsEarthCover", "multibeam echo sounder", "Coastal and Marine Hazards and Resources Program", "geospatial datasets", "seabed", "Bathymetry", "maps and atlases", "Pacific Ocean", "U.S. Geological Survey", "Marine Nearshore Subtidal", "USGS", "CMHRP", "State of California", "Marin County", "Transform Continental Margin", "Stinson Beach", "bathymetry and elevation", "Bolinas", "environment", "marine geophysics", "Seafloor Topography", "Northern California Ecoregion", "Bolinas Lagoon", "Marine Offshore Subtidal", "Continental/Island Shelf", "USGS:1512f147-5de9-4400-96de-be10635debbe", "oceans", "Pacific Coastal and Marine Science Center", "geoscientificInformation", "Rock Substrate", "bathymetry measurement", "bathymetry", "PCMSC", "Unconsolidated Mineral Substrate"], "modified": "2023-03-02T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-122.78, 37.81, -122.58, 37.97", "theme": ["geospatial"], "title": "Bathymetry--Offshore Bolinas, California"}
