The compilation of onshore data consisted of nearly one million Bouguer gravity anomaly values computed by using a reduction density of 2.67 grams per cubic centimeter. The offshore data consisted of approximately 800,000 free-air gravity anomaly values. USGS employees: Godson and Scheibe
Gravity anomalies are produced by density variations within the rocks of the Earth's crust and upper mantle. Mapping of these density variations is the primary use of gravity anomalies.
Are there legal restrictions on access or use of the data?
The USGS has made every effort to verify the veracity of this information, but is not liable for any inaccuracies.
