<P> 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 . </P>
