Sea ice thickness spatial extent, and open water within sea ice packs can vary rapidly in response to weather and climate. [1] Sea ice concentration is measured by satellites, with the Special Sensor Microwave Imager / Sounder (SSMIS), and the European Space Agency's Cryosat-2 satellite to map the thickness and shape of the Earth's polar ice cover.

In official context and legislation, the ice classes are usually spelled with Roman numerals, e.g. IA. [3] Classification societies may sometimes use somewhat different distinguishing marks for Finnish-Swedish ice classes; for example, 1A Super is defined as Ice Class I AA by the American Bureau of Shipping (ABS) and ICE(1A*) by DNV GL. [4]
Since the albedo of ice is much higher than that of water, ice concentration will regulate insolation in the polar oceans. When combined with ice thickness , it determines several other important fluxes between the air and sea, such as salt and fresh-water fluxes between the polar oceans (see for instance bottom water ) as well as heat transfer ...
The fate of the world's largest ice sheet is a major focus of nearly 1,500 academics and researchers who gathered this week in southern Chile for the 11th Scientific Committee on Antarctica ...
USCGC Healy at right breaks ice around the Russian-flagged tanker Renda, 250 miles (400 km) south of Nome, Alaska.. An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships.
Upward looking sonar (ULS) devices can be deployed under polar ice over a period of months or even years, and can provide a complete profile of ice thickness for a single site. [19] Sonars are directly measuring sea ice draft, so accurate estimate of sea ice thickness requires knowledge about snow thickness, snow and sea-ice density.
One of the varieties of ice navigation vessels are double-acting ships. To move through the ice, they use the combined effect of the ice-breaking shape of the ship's stern and the effect of the propellers on the ice. [14] These vessels may have the usual bulbous bow and may be capable of moving in ice only astern. Since ice sailing astern also ...
Hood’s ice cream also has the fewest grams of sugar per serving among the ice creams we tried, so if a lower sugar content is appealing, this brand delivers. Cheapism $5.19/1.5 quarts from Instacart
