Summary: The gravity station data (32,152 records) were compiled by the U. S. Geological Survey. This data base was received on February 23, 1993. Principal gravity parameters include observed gravity, Free-air anomalies and Bouguer anomalies. 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.

CAVEAT: Caution is recommended in using these data, which have been furnished to NGDC with minimal documentation. As part of our on-going data rescue efforts, NGDC will continue to seek improved documentation.
