Concentration and discharge data were sourced from public and/or published datasets and the Weighted Regressions on Time, Discharge, and Season model (Hirsch et al. 2010) was used to estimate monthly concentrations and flow-normalized concentrations for all sites over their period of record. Sites span eight climate zones, ranged from 18 degrees N to 70 degrees N, and vary in drainage area from < 1 km2 to nearly 3 million km2. These monthly concentration data were then used to cluster sites into average (i.e., average of all years) and annual (i.e., each year individually) seasonal regimes using a time-series clustering approach. The annual regimes were used to quantify how often a site moved among regimes over its period of record (i.e., stability). Site characteristics including climate zone, discharge, and concentration-discharge behavior were explored as potential drivers of cluster membership and stability.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9CXDEE8", "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.6511aeabd34e823a0275dc3e.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6511aeabd34e823a0275dc3e", "keyword": ["Canada", "Finland", "Norway", "Russia", "Sweden", "USGS:6511aeabd34e823a0275dc3e", "United States", "biogeochemistry", "phenology", "river", "silicon"], "modified": "2023-11-14T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-180.0000, 15.9613, 179.6484, 73.9225", "theme": ["geospatial"], "title": "Monthly dissolved silicon concentrations from 198 rivers in the Northern Hemisphere"}
