Regional and Local Anomaly Separation in the Almada Basin (Bahia State), Using Gravity Data from the Grace Satellite

We have detected in the Almada Basin, northeast Brasil, a high correlation between the regional gravity effects produced by the crust-mantle interface obtained from 2D forward modeling and the gravity data from the GRACE satellite. The altitude of the satellite mission of about 500 km works naturally as an upward continuation filter, allowing the use of this kind of data as an independent estimator of the regional component of the gravity field in the Almada Basin.
