Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted Regression on  Time, Discharge, and Season).  The load results represent the total mass of nitrogen, phosphorus, and suspended sediment that was exported from each of the NTN watersheds.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7RR1X68", "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.59da8c70e4b05fe04cc9b2d0.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_59da8c70e4b05fe04cc9b2d0", "keyword": ["United States", "suspended sediment", "phosphorus", "nitrogen", "Pennsylvania", "West Virginia", "Maryland", "nutrients", "rivers", "Virginia", "load analysis", "Chesapeake Bay Watershed", "Delaware", "water quality", "weighted regression", "Washington DC", "New York", "trends", "WRTDS", "USGS:59da8c70e4b05fe04cc9b2d0"], "modified": "2020-08-27T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-79.167480469182, 36.208470061656, -74.904785156852, 42.714410712674", "theme": ["geospatial"], "title": "Chesapeake Bay Nontidal Network 1985-2016: WRTDS output data"}
