These data were collected in 2022 on expedition TN403 (USGS Field Activity 2022-621-FA). Samples were taken to the USGS Pacific Coastal Marine Science Center for subsampling and geochemical analyses. Data include major, minor, and trace element concentrations, location information (latitude, longitude, depth), analytical methods, and instrument detection limits where available.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1DJPX9G", "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.68a50b3ed4be02198e361b59.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_68a50b3ed4be02198e361b59", "keyword": ["Assessments", "CMHRP", "Coastal and Marine Hazards and Resources Program", "Escanaba Trough", "Global Ocean Mineral Resources", "Gorda Ridge", "Material Resources", "Mineral Resources", "Nonliving Resources", "PCMSC", "Pacific Coastal and Marine Science Center", "Pacific Ocean", "Physical/Chemical Features", "U.S. Geological Survey", "USGS", "USGS:68a50b3ed4be02198e361b59", "chemical analysis", "geochemistry", "geoscientificInformation", "mass spectroscopy", "metallic mineral resources", "mineral resources", "oceans"], "modified": "2026-04-03T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-127.5477, 40.6957, -127.4463, 41.0822", "theme": ["geospatial"], "title": "Major, minor, and trace element data for rock samples from the Escanaba Trough (Gorda Ridge)"}
