The vector file is included in \"TransgressiveContours_SaltPointToDrakesBay.zip,\" which is accessible from https://pubs.usgs.gov/ds/781/SaltPointToDrakesBay/data_catalog_SaltPointToDrakesBay.html.\n\nAs part of the USGS's California State Waters Mapping Project, a 20-m grid of depth to the transgressive surface of the last glacial maximum was generated for the areas within the 3-nautical mile limit between Salt Point and Drakes Bay was generated from seismic-reflection data collected in 2009 supplemented with outcrop and geologic structure from DS 781. The resulting grid covers an area of approximately 550 sq km. The depth to the transgressive surface of the Last Glacial Maximum ranges between 0 and 102 meters.\n", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://pubs.usgs.gov/ds/781/", "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.2734a6ab-6077-4249-890a-f9807ed6fb9d.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_2734a6ab-6077-4249-890a-f9807ed6fb9d", "keyword": ["Bodega Bay", "Marin County", "Pacific Ocean", "Point Reyes", "Sonoma County", "State of California", "USGS:2734a6ab-6077-4249-890a-f9807ed6fb9d", "coastal geology", "environment", "geoscientificInformation", "geospatial datasets", "maps and atlases", "marine geology", "oceans", "sediment isopach", "sediment thickness", "seismic reflection methods", "seismic-reflection data", "stratigraphic thickness"], "modified": "2025-05-14T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-123.473993, 37.868433, -122.762732, 38.640196", "theme": ["geospatial"], "title": "Transgressive Contours--Salt Point to Drakes Bay, California"}
