Age-0 walleye were caught in Fox River during October 2014.  Total length, weight, age, and proportion of weight represented by water were determined for each of the walleye.  Whole-fish homogenates were prepared during 2014-2015 and during 2017.  Total mercury (HgT) concentration, methylmercury (MeHg) concentration, and mercury (Hg) isotope ratios were determined in the homogenates during 2014-2015 and during 2017-2018.  All mercury determinations were made at the USGS Mercury Research Laboratory in Middleton, Wisconsin.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9APFL8X", "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.5c091bbfe4b0815414d0bc39.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5c091bbfe4b0815414d0bc39", "keyword": ["Fox River", "Green Bay", "Lake Michigan", "USGS:5c091bbfe4b0815414d0bc39", "biota", "lower Green Bay", "mercury", "mercury contamination", "walleye"], "modified": "2020-08-20T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-88.6816, 44.3081, -87.1436, 45.5525", "theme": ["geospatial"], "title": "Fox River walleye mercury isotope data"}
