Claim:
1. A method of processing marine gravity data, the method comprising: obtaining an initial free-air anomaly per profile from raw data acquired by a ship equipped with a marine gravity meter traveling along a plurality of profiles on the sea; filtering out high-frequency components from the initial free-air anomaly using a power-profile moving average method to produce a filtered free-air anomaly; extracting a reference free-air anomaly from a data source: calculating a reference corrected free-air anomaly by performing a per-profile comparison for each of the plurality of profiles between the filtered free-air anomaly and the reference free-air anomaly, and shifting the filtered free-air anomaly in response to the reference free-air anomaly; and showing in a display a per-profile free-air anomaly using the reference corrected free-air anomaly.
