The geochemical landscape of northwestern Wisconsin and adjacent parts of northern Michigan and Minnesota (geochemical data files) | Info |
Updated aeromagnetic and gravity anomaly compilations and elevation-bathymetry models over Lake Superior
New gravity and magnetic compilations and elevation-bathymetry models compiled for the Lake Superior region, providing 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. Data are provide in GeoTiff, GXF, and CSV (for gravity station data) formats. |
