| Gravity Data for Southwestern Alaska (1294 records compiled) |
| The gravity station data (1294 records) were compiled by the Alaska Geological Survey
and the U.S. Geological Survey, Menlo Park, California. This data base was received
in September 1986. Principal gravity parameters include Free-air Anomalies and Simple
Bouguer Anomalies (no terrain correction applied) and topographic elevations to compute
the 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. The data are randomly
distributed within the boundaries of central Alaska. |
