A 2 kilometer Isostatic anomaly grid for the state of Nevada. Number of columns is 269 and number of rows is 394. The order of the data is from the lower left to the right and then up one row.

A 2 kilometer Bouguer anomaly grid for the state of Ohio. Number of columns is 187 and number of rows is 217. The order of the data is from the lower left to the right and then up one row.

This study of gravity data from Nevada is part of a statewide analysis of mineral resources. The main objective of the gravity study were: 1) to infer the structure and composition of the basement; 2) to determine the thickness of Cenozoic deposits. An iterative procedure based on the gravity data, a knowledge of the surface geology, and an estimate of the density of Cenozoic deposits was used to separate the isostatic residual gravity field into two component parts, a "basement" component and a "cover thickness" component.

A 1 kilometer Complete Bouguer Anomaly gravity grid of interior Alaska. Only those grid cells within 10 kilometers of a gravity data point have gravity values. Number of columns is 850 and number of rows is 600. The order of the data is from the lower left to the right and then up one row.

A 1 kilometer Complete Bouguer Anomaly gravity grid of interior Alaska. All grid cells within the rectangular data area (from 61 to 66 degrees North latitude and from 144 to 159 degrees West longitude) have interpolated data values. Number of columns is 850 and number of rows is 600. The order of the data is from the lower left to the right and then up one row.

In 1985, Dr. William F. Haxby of the Lamont-Doherty Geological Observatory of Columbia University prepared this data base of free-air gravity anomalies, based on the radar altimetry of the SEASAT satellite mission in 1978.

Gravity anomalies and sea surface heights have been computed on a 0.125 degree grid in the ocean areas from a combined GEOS3/SEASAT/GEOSAT altimeter data set. This data base was received in March 1993. The area of data coverage is latitude 72N to 72S and longitude 0E to 360E.

The 1x1 degree Terrestrial Mean Free-Air Gravity Anomaly and Geoid Undulations Data Base was compiled and developed by the Ohio State University. This data base was received in March 1993. Principal gravity parameters include mean elevation, mean free-air anomaly and source id. The gravity anomaly computation uses the Geodetic Reference System 1967 (GRS 67) theoretical formula. The data are global in coverage where data are available.
