Abstract Outlines gravimetric method based on use of observed gravitational potential of Earth. Characteristics of global geoid spherical harmonics are input data for method. Calculated 3D vertical and lateral sections show distribution of masses in all ranges of depths up to 3,500 km, geometry and sizes of density inhomogeneities, transformation of plumes at different depths, cross-section along boundary of Antarctic lithosphere plate, and dynamic features and links of Antarctic and Arctic with other regions in great depths.
