Dynamic topography results in uplift and subsidence events on Earth’s surface with amplitudes on the order of a kilometer over time periods of a few million years. These vertical motions are known to have influenced ice sheet evolution, but how dynamic topography has controlled the current state of present ice sheets is unknown. Here, we explore this by running ice sheet models to their equilibrium state after removing present-day dynamic topography. We find that Antarctic ice cover is significantly different without dynamic topography; the Marie Byrd Land sector of West Antarctica loses 1.542 ×106 gigatonnes of ice, while the Weddell Sea sector gains 1.23623 ×106 gigatonnes. In Greenland, we see ice loss in the east and large sectors of the ice sheet become marine based. Taken together, these findings indicate that present-day dynamic topography has played a major role in the equilibrium geometries of modern ice sheets.
