A Fast Forward and Inversion Strategy for Three-Dimensional Gravity Field
Mathematics, 2023 Obtaining a three-dimensional (3D) density distribution within a reasonable time is one of the most critical problems in gravity exploration. In this paper, we present an efficient 3D forward modeling and inversion method for gravity data.

Spectral methods in gravity inversion: the geopotential field and its derivatives
Annals of Geophysics, 1997 The 3D spectral analysis of the gravitational potential field for a given mass distribution is studied. The derived quantities, the gravitational force field and the gravity gradient tensor are computed in frequency space.

Seabed topography beneath Larsen C Ice Shelf from seismic soundings [PDF]
The Cryosphere, 2014 Seismic reflection soundings of ice thickness and seabed depth were acquired on the Larsen C Ice Shelf in order to test a sub-ice shelf bathymetry model derived from the inversion of IceBridge gravity data.

Minimum‐structure borehole gravity inversion [PDF]
SEG Technical Program Expanded Abstracts 2008, 2008 The borehole gravity technique has been well established in hydrocarbon exploration geophysics since the 1970's. The concept behind borehole gravity is simply to measure the variation in the Earth's gravitational field while traveling along a borehole. Densities both close to and far from the borehole can be derived from such measurements. However, the
