Wisconsin Gravity Data for the Marshfield Area
The gravity station data (8388 records) were compiled by Professor Ervin. This data base was received in April 1993. Principal gravity parameters include Free-Air Anomalies and Simple Bouguer Anomalies. Terrain corrections have also been computed. The observed gravity values are referenced to the International Gravity Standardization Net 1971 (IGSN 71). The gravity anomaly computation uses the Geodetic Reference System 1967 (GRS 67) theoretical gravity formula. The data are randomly distributed within the area of central Wisconsin between 44 and 45 degrees north latitude.
