How deep is the frost line in Antarctica?

Antarctica is the coldest, driest, windiest, and highest continent on Earth. It is also home to the thickest ice sheet on the planet. The average thickness of the ice sheet in Antarctica is about 2,160 meters (7,087 feet). The deepest point on the continent is Bentley Subglacial Trench, which is 2,555 meters (8,383 feet) below sea level. The frost line in Antarctica is the depth at which the ground remains frozen all year round. The frost line varies depending on the location and the time of year. In general, the frost line is shallower in the coastal regions of Antarctica and deeper in the interior. The frost line also varies depending on the type of soil. In sandy soil, the frost line is shallower than in rocky soil. The average frost line in Antarctica is about 1 meter (3 feet) deep.
