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 nine RIM watersheds.  When summed, the loads from the nine RIM stations represents the total load delivered from nearly eighty-percent of the bay watershed.  To determine the trend in loads, the annual load results are flow normalized to integrate out the year-to-year variability in river discharge.  The trend in load is derived from the  flow-normalized load timeseries and represents the change in load resulting from changes in sources, delays associated with storage or transport of historical inputs, and (or) implemented management actions.\", \"distribution\": [{\"@type\": \"Distribution\", \"accessURL\": \"http://dx.doi.org/10.5066/F7Q81B5N\", \"description\": \"Landing page for access to the data\", \"format\": \"XML\", \"mediaType\": \"application/http\", \"title\": \"Digital Data\"}, {\"@type\": \"Distribution\", \"description\": \"The metadata original format\", \"format\": \"XML\", \"mediaType\": \"text/xml\", \"title\": \"Original Metadata\"}], \"identifier\": \"USGS:577e6a3ce4b0ef4d2f44ee37\", \"keyword\": [\"Nitrogen Trends\", \"Phosphorus Trends\", \"Suspended Sediment Trends\", \"USGS:577e6a3ce4b0ef4d2f44ee37\", \"Water Quality\"], \"modified\": {\"date\": \"2020-08-27T00:00:00Z\", \"timezone\": \"UTC\", \"timezone_type\": 3}, \"publisher\": {\"@type\": \"org:Organization\", \"name\": \"U.S. Geological Survey\", \"subOrganizationOf\": \"Department of Interior\"}, \"spatial\": [\"{\\\"spatial\\\":{\\\"type\\\":\\\"Bounding Box\\\",\\\"coordinates\\\":\\\"-79.167480469182, 36.208470061656, -74.904785156852, 42.714410712674\\\"}}\"], \"theme\": [\"geospatial\"], \"title\": \"Nitrogen, Phosphorus, and Suspended-Sediment Loads and Trends measured in Nine Chesapeake Bay Tributaries: Trends in Annual Loads, Water Years 1985 - 2015\"}","source_transform":null,"status":"error"}
