These data represent over 40 years of gravity surveying in the state of Minnesota. This release is the first significant revision of the Minnesota gravity database since the compilation by Chandler and Schaap (1991), that the reader is referred to for information on the older data. Since that compilation, approximately 2000 stations have been added from data used to support a variety of projects for the Minnesota Geological Survey (MGS). Additionally, archival data not available for the earlier compilation are now included.
