|DMA Antarctic Gravity Data
|The gravity station data (65,164 records) were gathered by various governmental organizations
(and academia) using a variety of methods. The data base was received in August, 1993.
Principal gravity parameters include Free-air Anomalies and Simple Bouguer Anomalies
(no terrain correction applied). 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 south of 50 degrees South.
