Bouguer gravity anomaly

Gravity data inversion or interpretation requires the removal of the gravitational effects of the a priori known geologic and/or morphologic features within the Earth’s system to model and reveal the remaining signals of the unknown anomalous subsurface density distributions. The Bouguer gravity anomalies reduced by the normal gravitational field of the Earth and the gravitational attraction of the topographic masses above the sea level are frequently used in geophysics for this purpose.

This paper presents a comparative study of two different forward methods such as the space domain method and the frequency domain method. The performance of each method was evaluated on two synthetic models. Finally, the more effective method was applied to calculate Bouguer gravity anomaly in the East Vietnam Sea and adjacent areas using the latest available dataset from the TOPEX mission.
