Web31 Oct 2024 · In oceanography the marine geoid represents an important reference surface relative to which the ocean dynamic topography (ODT) can be inferred from sea surface height (SSH) measurements obtained by satellite altimetry. In the past temporal variations of the geoid were presumed to be small compared to other error sources and were neglected. WebBy definition, the geoid describes the irregular shape of the earth and is the true zero surface for measuring elevations. Because the geoid surface cannot be directly observed, heights above or below the geoid surface …
