Wolock, U.S. Geological Survey, written commun., 2008).\n\t\t\nThe MRB_E2RF1 catchments are based on a modified version of the U.S. Environmental Protection \nAgency's (USEPA) RF1_2 and include enhancements to support national and regional-scale \nsurface-water quality modeling (Nolan and others, 2002; Brakebill and others, 2011).\n\t\t\nData were compiled for every MRB_E2RF1 catchment for the conterminous United States covering \nNew England and Mid-Atlantic (MRB1), South Atlantic-Gulf and Tennessee (MRB2), the Great Lakes, \nOhio, Upper Mississippi, and Souris-Red-Rainy (MRB3), the Missouri (MRB4), the Lower Mississippi, \nArkansas-White-Red, and Texas-Gulf (MRB5), the Rio Grande, Colorado, and the Great basin (MRB6), \nthe Pacific Northwest (MRB7) river basins, and California (MRB8).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P98VCZLM", "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.c438ae58-988f-44a9-8a8d-3d70016274e4.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_c438ae58-988f-44a9-8a8d-3d70016274e4", "keyword": ["CALI", "California", "Catchment", "Contact time", "Conterminous United States", "GLMR", "Great Lakes, Ohio, Upper Mississippi, and Souris-Red-Rainy", "Inlandwaters", "LMTG", "Lower Mississippi, Arkansas-White-Red, and Texas-Gulf", "MORI", "MRB", "MRB2", "MRB3", "MRB4", "MRB5", "MRB7", "MRB8", "MRB_E2RF1", "MRB_E2RF1WS", "Major River Basins", "Missouri", "NAWQA", "PANW", "Pacific Northwest", "SAGT", "SPARROW", "South Atlantic-Gulf and Tennessee", "USGS:c438ae58-988f-44a9-8a8d-3d70016274e4", "environment", "geoscientificInformation", "inlandWaters"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-127.910792, 23.243486, -65.327751, 51.657387", "theme": ["geospatial"], "title": "Attributes for MRB_E2RF1 Catchments in Selected Major River Basins of the Conterminous United States: Contact Time, 2002"}
