Drenth", "hasEmail": "mailto:bdrenth@usgs.gov"}, "description": "This data release provides digital flight line data for a high-resolution airborne magnetic survey over parts of northwestern Minnesota near the town of Mentor. The airborne survey was funded by the Earth Mapping Resources Initiative and was designed to meet complementary needs related to geologic mapping and characterization of mineral resource potential. A total of 40,139-line km of magnetic data were acquired over an irregular-shaped area of 9140 km2. Data were collected from a fixed-wing aircraft flown at mean terrain clearance of 120 meters (m) above topography along N-S flight lines spaced at 250 m intervals. Tie lines were flown in an E-W direction every 2500 m. Data were collected by EDCON-PRJ and NV5 Geospatial, Inc. under contract with the USGS using a fixed wing aircraft with a magnetometer mounted in the tail stinger. The survey operated out of the Crookston, Minnesota airport from May of 2021 to July of 2021. Files that are available in this child item include flight line data for the magnetic survey and a geotiff of the gridded total-field anomalies.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P97D2JJE", "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.633e0098d34e342aee056924.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_633e0098d34e342aee056924", "keyword": ["Silver River", "Polk County", "United States", "Red Lake County", "northwestern Minnesota", "Thief River Falls", "Clearwater River", "magnetic field (earth)", "United States of America", "geophysics", "geospatial datasets", "Mineral Resources Program", "Red Lake River", "economy", "Marsh River", "Earth Mapping Resources Initiative", "GGGSC", "U.S. Geological Survey", "USGS:633e0098d34e342aee056924", "Clay County", "USA", "USGS", "Geology, Geophysics, and Geochemistry Science Center", "MRP", "Mentor Complex", "airborne geophysical survey", "horizontal magnetic gradiometry", "Thief River", "Minnesota", "Becker County", "Marshall County", "vertical magnetic gradient", "Pennington County", "Norman County", "EarthMRI", "geoscientificInformation", "aeromagnetic surveying", "Wild Rice River"], "modified": "2023-01-24T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-95.649796, 46.945464, -96.887468, 48.340636", "theme": ["geospatial"], "title": "Airborne magnetic survey, northwestern Minnesota, 2021"}
