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 RIM watersheds.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P93PZGMM", "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.60ef201bd34e93b366704f13.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_60ef201bd34e93b366704f13", "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", "WRTDS-Kalman", "USGS:60ef201bd34e93b366704f13", "New York", "trends", "WRTDS", "Kalman filtering"], "modified": "2021-09-16T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-79.167480469182, 36.208470061656, -74.904785156852, 42.714410712674", "theme": ["geospatial"], "title": "Chesapeake Bay River Input Monitoring Network 1985-2020: WRTDS input data"}
