An ice floe (/ f l oʊ /) is a large pack of floating ice often defined as a flat piece at least 20 m across at its widest point, and up to more than 10 km across. [1] Drift ice is a floating field of sea ice composed of several ice floes. They may cause ice jams on freshwater rivers, and in the open ocean may damage the hulls of ships.
Arctic sea ice is the polar bear's habitat. It has been declining at a rate of 13% per decade because the temperature is rising at twice the rate of the rest of the world. [79] [119] By the year 2050, up to two-thirds of the world's polar bears may vanish if the sea ice continues to melt at its current rate. [120]
The group drifted over 1,800 miles (2,900 km) on the ice floe for the next six months [59] before being rescued off the coast of Newfoundland by the whaler Tigress on April 30, 1873. [60] All probably would have perished had the group not included the skilled Inuit hunters Ipirvik and Hendrik, who were able to kill seal on several occasions.

Similarly, ships can get stuck between drift ice floes. The two major ice packs are the Arctic ice pack and the Antarctic ice pack. The most important areas of pack ice are the polar ice packs formed from seawater in the Earth's polar regions: the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of the Southern Ocean. Polar packs ...
The combination of warming temperatures and strong winds can make ice floes most likely to occur in late winter and early spring, so make sure you pack some common sense if you’re planning on ...
