Sea ice arises as seawater freezes. Because ice is less dense than water, it floats on the ocean's surface (as does fresh water ice). Sea ice covers about...

The Sea of Ice, (German: Das Eismeer) (1823–1824), is an oil painting that depicts a shipwreck in the Arctic by the German Romantic painter Caspar David...

Sea ice in the Arctic region has declined in recent decades in area and volume due to climate change. It has been melting more in summer than it refreezes...

melting ice sheets and glaciers accounted for 44% of sea level rise, with another 42% resulting from thermal expansion of water.: 1576  Sea level rise...

sea ice is the sea ice of the Southern Ocean. It extends from the far north in the winter and retreats to almost the coastline every summer. Sea ice is...

covered by ice (sea ice, glacial ice, or snow) year-round, and nearly all parts of the Arctic experience long periods with some form of ice on the surface...

the entire Barents Sea is more or less completely ice-free. From 1920 to 1944, Finland's territory also reached the Barents Sea. The Liinakhamari harbour...

The loss of grounded ice (as opposed to floating sea ice) is the primary contributor to sea level rise. Humans have been using ice for various purposes...

Arctic ice pack is the sea ice cover of the Arctic Ocean and its vicinity. The Arctic ice pack undergoes a regular seasonal cycle in which ice melts in...

to more than 10 km across. Drift ice is a floating field of sea ice composed of several ice floes. They may cause ice jams on freshwater rivers, and in...

discussed ice as a means of transport. The Swedish mining expert Daniel Tilas (1712–1772) was, in 1742, the first person to suggest drifting sea ice was a...

Drift ice, also called brash ice, is sea ice that is not attached to the shoreline or any other fixed object (shoals, grounded icebergs, etc.). Unlike...

glaciers, polar ice caps and sea ice. Over geological timescales, changes in the shape of the oceanic basins and in land/sea distribution affect sea level. In...

Ice–albedo feedback is a climate change feedback, where a change in the area of ice caps, glaciers, and sea ice alters the albedo and surface temperature...

polar ice cap visible (courtesy NASA) Earth's North Pole is covered by floating pack ice (sea ice) over the Arctic Ocean. Portions of the ice that do...

it feeds its young only while on ice. The grey seal is adapted to reproducing also with no ice in the sea. The sea ice also harbors several species of...

waters that are almost permanently covered with constantly shifting sea ice. The sea depth at the North Pole has been measured at 4,261 m (13,980 ft) by...

as "sea-ice entrapment". Narwhals drown if open water is no longer accessible and ice is too thick for them to break through. Breathing holes in ice may...

Frost flowers are ice crystals commonly found growing on young sea ice and thin lake ice in cold, calm conditions. The ice crystals are similar to hoar...

surface temperatures can rise to over 30 °C (86 °F). Near the poles where sea ice forms, the temperature in equilibrium is about −2 °C (28 °F). In all parts...
