Abstract

Summary

In the calculation of the Earth’s shape the mass distribution under the ellipsoid is assumed to be homogeneous. A local excess of mass within the ellipsoid will deviate from the local gravity.

As a result of the uneven distribution and heterogeneity of the Earth’s internal mass, the geoid is a corrugated equipotential surface. Corrugations may be positive (the geoid being above the ellipsoid) when there is a mass excess or they may be negative (the geoid being under the ellipsoid) when there is a difficult table in the basement.

In this paper we have calculated the geoid and quasi-geoid for the territory of Romania and overlaid them on the geological elements of depth.
