    dct:description "The gravity station data (5,905 records) were compiled by the U. S. Geological Survey. This data base was received on July 11, 1997. Principal gravity parameters include observed gravity, Free-air anomalies and Bouguer anomalies. The Bouguer gravity anomaly values were computed using the 1967 gravity formula (International Association of Geodesy, 1971). See Open-File Report 90-265 for further information." ;
