The USGS range-wide sea otter census has been undertaken each year since 1982, using consistent methodology involving both ground-based and aerial-based counts. The spring provides the primary basis for gauging population trends by State and Federal management agencies. Sea otter distribution in California (the mainland range) is considered to comprise a band of potential habitat stretching along the coast of California, and bounded to the north and south by range limits defined by combining independent otters within a moving window of 10-kilometer stretches of coastline (as measured along the 10-meter bathymetric contour; 20 contiguous ATOS intervals each) and taking the northern and southern ATOS values, respectively, of the northernmost and southernmost stretches in which at least five otters were counted for at least 2 consecutive spring surveys during the last 3 years.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9B2KNB3", "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.5d85427ce4b0c4f70d086f23.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5d85427ce4b0c4f70d086f23", "keyword": ["California", "Central California Coastal", "Southern California Coastal", "USGS:5d85427ce4b0c4f70d086f23", "aerial counts", "biogeography", "biota", "distribution", "environment", "mammals", "ocean", "range", "sea otter census", "sea otters", "shore counts"], "modified": "2020-08-30T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-122.373376708, 34.4181571927, -120.273461145, 37.196219752", "theme": ["geospatial"], "title": "Annual California Sea Otter Census: 2019 Range Extent Shapefile"}
