These data accompany the pamphlet and map sheets of Johnson, S.Y., Dartnell, P., Golden, N.E., Hartwell, S.R., Greene, H.G., Erdey, M.D., Cochrane, G.R., Watt, J.T., Kvitek, R.G., Manson, M.W., Endris, C.A., Dieter, B.E., Krigsman, L.M., Sliter, R.W., Lowe, E.N., and Chin, J.L. (S.Y. Johnson and S.A. Cochran, eds.), 2015, California State Waters Map Series\u2014Offshore of Tomales Point, California: U.S. Geological Survey Open-File Report 2015\u20131088, pamphlet 38 p., 10 sheets, scale 1:24,000, https://doi.org/10.3133/ofr20151088.\nThe bathymetry map of the Offshore of Tomales Point Map Area, California, was generated from bathymetry data collected by California State University, Monterey Bay (CSUMB), by Fugro Pelagos, and by the U.S. Geological Survey. 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 234-kHz and 468-kHz SEA SWATHPlus phase-differencing sidescan sonars. 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. NOTE: 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", "accessURL": "https://pubs.usgs.gov/ds/781/OffshoreTomalesPoint/data_catalog_OffshoreTomalesPoint.html", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.7aba9039-5ad0-44ed-889a-d8e8d69ec910.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_7aba9039-5ad0-44ed-889a-d8e8d69ec910", "keyword": ["sonar methods", "distributions", "imageryBaseMapsEarthCover", "multibeam echo sounder", "Coastal and Marine Hazards and Resources Program", "geospatial datasets", "seabed", "Bathymetry", "maps and atlases", "USGS:7aba9039-5ad0-44ed-889a-d8e8d69ec910", "Pacific Ocean", "U.S. Geological Survey", "Tomales Bay", "Marine Nearshore Subtidal", "USGS", "CMHRP", "State of California", "Marin County", "Transform Continental Margin", "bathymetry and elevation", "environment", "marine geophysics", "Seafloor Topography", "Northern California Ecoregion", "Marine Offshore Subtidal", "Continental/Island Shelf", "oceans", "Pacific Coastal and Marine Science Center", "geoscientificInformation", "Rock Substrate", "bathymetry measurement", "bathymetry", "PCMSC", "Tomales Point", "Unconsolidated Mineral Substrate"], "modified": "2023-03-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-123.10, 38.10, -122.90, 38.25", "theme": ["geospatial"], "title": "Bathymetry--Offshore of Tomales Point, California"}
