Seven of the lakes were monitored by the National Ecological Observatory Network (NEON), and one by the U.S. Geological Survey (USGS Site No. 01670144). The study lakes span a gradient from oligotrophic to hypereutrophic conditions and were analyzed to evaluate ecosystem metabolism as potential early warning indicators (EWIs) of ecological state change in real-world ecosystems.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P13AKNWB", "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.6968f6a2d4be0249f340d72e.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6968f6a2d4be0249f340d72e", "keyword": ["Crampton Lake", "Lake Anna", "Lake Barco", "Lake Suggs", "Little Rock Lake", "Prairie Lake", "Prairie Pothole", "Toolik Lake", "USGS:6968f6a2d4be0249f340d72e", "algae", "freshwater ecosystems", "inlandWaters", "photosynthesis"], "modified": "2026-06-23T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-157.1484, 26.1160, -76.9922, 69.5345", "theme": ["geospatial"], "title": "Lake metabolism model inputs and outputs from select U.S. lakes, 2018-2025"}
