These samples were collected to obtain representative samples of surficial geologic map units.  This Data Release is related to ongoing USGS mapping activities at U.S. Army Base Fort Drum, New York.\nLaboratory work was conducted using sediment analysis instrumentation housed in the Bascom Laser Diffraction Sedimentology Laboratory at the U.S. Geological Survey in Reston, Virginia.  Samples underwent laser diffraction PSA using a Beckman Coulter LS 13 320 XR particle size analyzer.  pXRF analysis was conducted on representative subsamples using a Bruker S1 Titan instrument on a benchtop stand.\nThis work is a collaboration with the Fort Drum Environmental Division and was funded by the National Cooperative Geologic Mapping Program.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P13TVQX9", "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.6a7a25fb1ba49b951e8403df.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6a7a25fb1ba49b951e8403df", "keyword": ["FBGC", "Florence Bascom Geoscience Center", "Fort Drum", "Jefferson County", "Lake Iroquois", "Munsell", "New York", "Quaternary", "U.S. Geological Survey", "USGS", "USGS:6a7a25fb1ba49b951e8403df", "X-ray fluorescence", "XRF", "color", "delta", "geochemistry", "geologic mapping", "geoscientificInformation", "glacial", "glacial lake", "glaciation", "grain size", "pXRF", "particle size", "sedimentology", "sieving"], "modified": "2026-09-03T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-75.8496, 44.0066, -75.3765, 44.2602", "theme": ["geospatial"], "title": "Multi-proxy sedimentological data from U.S. Army Base Fort Drum, Jefferson County, New York, 2026"}
