Frozen sea in winter. The sea ice covers with snow and becomes about 1 to 3 meters thick. In spring a combined raise of temperature, change in ocean currents and strong winds break it up and carry it away as floating chunks ('pack'). Sea ice is dangerous to walk on as it contains cracks ('rivers'), can be thin or very soft and can be carried away in its entirety by strong katabatic winds in a matter of hours.
A solid layer of ice that forms in the Arctic Ocean, sometimes referred to as pack ice, the pack ice expands in winter and recedes in summer.
1. Specifically, ice formed by the freezing of seawater; as opposed, principally, to land ice. In brief, it forms first as lolly ice ( frazil crystals), thickens into sludge, and coagulates into sheet ice, pancake ice, or into floes of various shapes and sizes. Thereafter, sea ice may develop into pack ice and/or become a form of pressure ice. 2. Generally, any ice floating in the sea.
Any form of ice found at sea that has originated from freezing of sea water. It does not include lake ice, river ice or glacier ice.
Ice which covers an ocean or sea; includes mostly continuous pack ice, broken only by narrow open water " lead s" or wider " polyna s", and discrete ice floes.
A thin layer of frozen seawater. Sea ice acts as an insulator between the cold air and the warmer water below.
During the winter, large sections of the Arctic ocean and adjacent seas freeze into patches of ice. These patches of sea ice may be carried by currents and winds as far south as Newfoundland, Canada. See related web page.
The area of frozen sea stretching out from the land.
Ice formed by the freezing of the surface of the sea.
solid water that forms when ocean or sea water freezes
ice that forms in salt water
A general term for any ice that forms from frozen seawater. Sea ice covers large parts of polar waters in the winter and melts back each summer.
any form of ice found at sea which has originated from the freezing of sea water.
Ice that is formed by the freezing of sea water. It forms first as small crystals, thickens into sludge, and coagulates into sheet ice, pancake ice, or ice floes of various shapes and sizes.
Sea ice is formed from ocean water that freezes. Because the oceans consist of saltwater, this occurs at about minus 1.8 °C.
