The free-air gravity anomaly grid was derived from raw gravity data acquired with a Bell BGM-3 gravimeter and converted to mGal values using the meter constant. A 10 minute cosine taper was then applied to the 1 second values and output at 10 second intervals. Eötvös corrections for ship speed, cour...
