how deep is the ice at the north pole
Polar ice cap Earth's North Pole is covered by floating pack ice (sea ice) over the Arctic Ocean. Portions of the ice that do not melt seasonally can get very thick, up to 3–4 meters thick over large areas, with ridges up to 20 meters thick. One-year ice is usually about 1 meter thick. The area covered by sea ice ranges between 9 and 12 million km². In addition, the Greenland ice sheet covers about 1.71 million km² and contains about 2.6 million km³ of ice. When the ice breaks off (calves) it forms icebergs scattered around the northern Atlantic.[2]
South Magnetic Pole The South Magnetic Pole is constantly shifting due to changes in the Earth's magnetic field. As of 2005 it was calculated to lie at 64°31′48″S 137°51′36″E﻿ / ﻿64.53000°S 137.86000°E﻿ / -64.53000; 137.86000,[2] placing it off the coast of Antarctica, between Adélie Land and Wilkes Land. In 2015 it lay at 64°17′S 136°35′E﻿ / ﻿64.28°S 136.59°E﻿ / -64.28; 136.59 (est).[3] That point lies outside the Antarctic Circle. Due to polar drift, the pole is moving northwest by about 10 to 15 kilometres (6 to 9 mi) per year. Its current distance from the actual Geographic South Pole is approximately 2,860 km (1,780 mi).[1] The nearest permanent science station is Dumont d'Urville Station. Wilkes Land contains a large gravitational mass concentration.
