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.  The file containing annual loads for all applicable NTN monitoring stations is provided in the \"Attached Files\" section. \nFirst posted: February 18, 2020 (available from author)\nRevised: May 2020 (version 2.0)", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P931M7FT", "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.5e2207b3e4b014c853036d6a.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5e2207b3e4b014c853036d6a", "keyword": ["Chesapeake Bay Watershed", "Delaware", "Maryland", "New York", "Pennsylvania", "USGS:5e2207b3e4b014c853036d6a", "United States", "Virginia", "WRTDS", "Washington DC", "West Virginia", "load analysis", "nitrogen", "nutrients", "phosphorus", "rivers", "suspended sediment", "trends", "water quality", "weighted regression"], "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 1985-2018: Annual loads (ver. 2.0, May 2020)"}
