WebMay 31, 2024 · A geoid represents a hypothetical surface (mean sea level) that the earth’s oceans would follow based solely on gravitational and rotational forces. The geoid surface extends under or over the landmasses and is irregular as it “undulates” above and below the ellipsoid due to irregularities in the mass distribution within the earth. WebThe geoid is in essence an equipotential surface of the actual gravitational field. In the vicinity of a local mass excess that adds potential Δ U to the normal Earth’s potential at a point, the surface must warp outward in order to keep the total potential constant.
