We developed and applied a novel numerical scheme for a gravimetric forward modelling of the Earth’s crustal density structures based entirely on methods for a spherical analysis and synthesis of the gravitational field. This numerical scheme utilises expressions for the gravitational potentials and their radial derivatives generated by the homogeneous or laterally varying mass density layers w...

Abstract The coastal marine gravity field is not well modelled due to poor data coverage. Recent satellite altimeters provide reliable altimetry observations near the coast, filling gaps between open ocean and land. We show potential of recent for modelling using least squares collocation technique. Gravity prediction error coast better than 4 mGal. anomalies are validated with sparse shipborne...

In this study, a sexaxial figure of the Earth was created using randomly distributed 6400 control points on geoid, which generated by EGM2008 gravity model. The shape ellipsoid is defined its six orthogonal axes. To construct new geometric figure, eight triaxial ellipsoids were fitted to Cartesian coordinates in each octant geoid least squares method. Its origin constrained coincide with centre...
