Updated gravity stations and anomaly compilation over Lake Superior
New gravity compilation has been compiled for the Lake Superior region. The gravity compilation includes survey stations available from Natural Resources Canada, National Centers for Environmental Information (formerly National Geophysical Data Center), Minnesota Geological Survey, and U.S. Geological Survey. Individual databases were combined and duplicates were removed resulting in a database of 63,880 gravity stations. The gravity station data were reprocessed from observed gravity to simple Bouguer anomaly following standard methods that depend on the station type (for example, land, lake surface, or lake bottom observation) and used a reduction density of 2,670 kg/m3. The compilation provides a consistent dataset appropriate for gravity modeling that extends across Lake Superior shores.
