Static Gravity Field Anomalies
The terrestrial gravity information was taken from the DTU10 global gravity field. Shown here are the so-called free air gravity deviations from an ideal ellipsoidal Earth model, in units of milli-gal. Areas colored yellow, orange or red are areas where the actual gravity field is larger than the featureless-Earth model predicts, while the progressively darker shades of blue indicate places where the gravity field is less.
