Nettet15. jun. 1997 · How sensitive are doubled CO 2 simulations to GCM control-run sea ice thickness and extent? This issue is examined in a series of 10 control-run simulations with different sea ice and corresponding doubled CO 2 simulations. Results show that with increased control-run sea ice coverage in the Southern Hemisphere, temperature … NettetSea ice properties are very different from those of lake or river ice. The reason for the difference is that when sea water freezes, roughly one-third of the salt in the sea water is initially entrapped within the ice in the form of brine inclusions. As a result, initial ice salinities are typically in the range 10–12‰.

Sea ice is an important component of the Earth’s climate system. The sea ice cover is highly heterogeneous and discontinuous. In the marginal ice zone, there are low concentration, low thickness floes of varying sizes and shapes (Rothrock & Thorndike, 1984).In the ice pack interior, a region with generally thicker …
NettetSea ice is formed by freezing the ocean surface (at about -1.8° C) and is a major and highly-dynamic component of the Earth’s cryosphere. Each year, sea ice transforms a vast area of the Southern Ocean south of ~55° S (Fig. 1), with its coverage increasing more than five-fold from 2-4 million km 2 in February to 19-20 million km 2 in September …
