These data provide continuous sets of observations for geologic interpretations spanning political boundaries such as US States and the US-Canada border where bedrock geology is largely concealed beneath glacial deposits and surface water. These data are providing constraints for on-going 3D geologic modeling of the Midcontinent Rift System and are helping to understand the metallogeny of the region.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7F18X8S", "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.57067fc5e4b032f77a8a437c.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_57067fc5e4b032f77a8a437c", "keyword": ["Great Lakes", "Lake Superior", "Michigan", "Minnesota", "Ontario", "USGS:57067fc5e4b032f77a8a437c", "Wisconsin", "aeromagnetic surveying", "bathymetry", "bouguer anomaly", "digital elevation models", "free-air anomaly", "geoscientificInformation", "geospatial datasets", "gravimeter measurement", "gravitational field (earth)", "magnetic field (earth)", "topography"], "modified": "2020-09-29T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-93.579236, 44.345422, -83.453750, 49.640125", "theme": ["geospatial"], "title": "Updated aeromagnetic and gravity anomaly compilations and elevation-bathymetry models over Lake Superior"}
