The survey area was Carpinteria Salt Marsh, California USA, which comprises 9 Ha tidal channels, 2 Ha salt flats, 17 Ha upland habitat, 6 Ha tidal pans, 52 Ha vegetated marsh, 2 Ha tidal flats. Using nearly 4,000 transects in potential snail habitat, we mapped snails throughout the estuary. Specifically, we systematically placed transects at intervals stratified within targeted habitat types: channels, pans, or marsh (or planar habitat that was mixed marsh and pan). At a quarter of the quadrats, we also estimated snail size-frequency distributions. Because we recorded the location of each quadrat, these data can be used to map the distribution of snails throughout this estuary.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "http://doi.org/10.5066/F7PG1PWZ", "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.582a508be4b0c253bdff7d38.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_582a508be4b0c253bdff7d38", "keyword": ["California", "Carpinteria", "Carpinteria Salt Marsh Reserve", "Santa Barbara County", "USGS:582a508be4b0c253bdff7d38", "distribution", "estuary", "habitat", "mapping", "salt marsh", "snail", "trematodes"], "modified": "2020-09-11T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-119.54535349, 34.394584289, -119.5262487, 34.405836436", "theme": ["geospatial"], "title": "Distribution and mapping of the snail Cerithideopsis (Cerithidea) californica at Carpinteria Salt Marsh, California USA, June to August 2012"}
