In this project, you will use 2D gravity modeling software in an offshore setting to calculate the 2D gravity effect of the bathymetry. This gravity effect (2D or Simple Bouguer correction) will then be applied using profile processing software to the Free-Air gravity thus producing Bouguer gravity. Most of the signal in Free-Air gravity processed to sea level is from the large density contrast at the water-sediment interface. This same type of large density contrast but at the air-topography interface is what necessitates the Bouguer correction for onshore gravity data. Without the correction, the gravity data profile is largely a reflection of the bathymetry.
