Applying both Free Air and Bouguer corrections to gravity readings is appropriate when isolating density anomalies. The Free Air anomaly adjusts gravity readings from the reference ellipsoid to the station location, accounting for elevation effects. However, this does not eliminate the influence of topographic masses, which is addressed by the Bouguer correction. The Bouguer correction removes the excess mass between the gravity station and the datum, typically approximated as a flat plate. For accurate results, these corrections should be applied consistently across all gravity readings, alongside necessary adjustments for instrument drift and latitude. The Free Air correction adds approximately 3.086 g.u./metre for elevation, while the Bouguer correction uses a mathematical formula involving density, gravitational constant, and plate thickness. In regions with significant topography, more complex corrections may be needed, requiring computational methods for precision.
