Project: 511 – 2D Model Single layer – 1 density contrast Onshore

In this project, you will use 2D gravity modeling software in an onshore setting to calculate the 2D gravity effect of the topography.
This effect, the 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 onshore Free-Air gravity is from the large density contrast at the air-topography interface.
This same type of large density contrast but at the water-sediment interface is what necessitates the Bouguer correction for offshore gravity data.
Without the correction, mapped gravity data is largely a reflection of the topography.
