During the 2015 EPA NCCA, samples were collected at 732 sites for analysis of algal toxins and cyanotoxins at the Organic Geochemistry Research Laboratory (OGRL) at the U.S. Geological Survey Kansas Water Science Center (KSWSC) by liquid chromatography triple quadrupole mass spectrometry (LC/MS/MS). Samples from the Atlantic, Gulf, and Pacific coasts of the conterminous U.S. were analyzed for anatoxin-a, cylindrospermopsin, domoic acid, dinophysistoxin-1, dinophysistoxin-2, gymnodimine, 10 microcystin congeners, nodularin, okadaic acid, pectenotoxin-2, and 13-desmethyl spirolide c.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9AW1K45", "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.5fda4b1dd34e30b9123ce48e.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5fda4b1dd34e30b9123ce48e", "keyword": ["13-desmethyl spirolide c", "Alabama", "California", "Connecticut", "Delaware", "Florida", "Georgia", "Louisiana", "Maine", "Maryland", "Massachusetts", "Mississippi", "New Hampshire", "New Jersey", "New York", "North Carolina", "Oregon", "Rhode Island", "South Carolina", "Texas", "USGS:5fda4b1dd34e30b9123ce48e", "United States", "Virginia", "Washington", "algal toxins", "anatoxin-a", "chemical analysis", "cyanotoxins", "cylindrospermopsin", "dinophysistoxin-1", "dinophysistoxin-2", "domoic acid", "environmental health", "gymnodimine", "liquid chromatography", "mass spectrometry", "microcystins", "nodularin", "okadaic acid", "pectenotoxin-2"], "modified": "2025-02-27T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-124.3177245, 24.70726415, -67.34738635, 48.9119915", "theme": ["geospatial"], "title": "2015 National Coastal Conditions Assessment: Algal Toxins and Cyanotoxins in United States Estuary Samples Detected by Liquid Chromatography Triple Quadrupole Mass Spectrometry (LC/MS/MS)"}
