Mean sea level is
WebThe theoretical mean sea level (or theoretical mean water, MW) is an estimate for the long-term mean value (more precisely, expectation value) of sea level, made for practical purposes. Land uplift, global sea level rise, as well as changes in the Baltic Sea water balance are taken into account. Because of these changes the theoretical mean sea ... WebJun 3, 2024 · The geoid is the shape that Earth’s ocean surface would take if the only influences acting upon it were gravity and Earth’s rotation. Changes in the solid Earth affect Earth’s gravitational field, causing the height of Earth’s geoid to vary by up to 100 meters (328 feet) around the globe.
