Regions of rapid sea ice change: An inter-hemispheric seasonal comparison
[1] This bi-polar analysis resolves ice edge changes on space/time scales relevant for investigating seasonal iceocean feedbacks and focuses on spatio-temporal changes in the timing of annual sea ice retreat and advance over 1979/ 80 to 2010/11. Where Arctic sea ice decrease is fastest, the sea ice retreat is now nearly 2 months earlier and subsequent advance more than 1 month later (compared t...
متن کاملSeasonal change of antarctic sea ice cover.
The winter expansion of the sea ice surrounding Antarctica and the subsequent retreat of the ice in summer may be linked with the wind stress acting on the Southern Ocean in conjunction with the heat exchange in open water regions within the ice fields.
متن کاملAlbedo evolution of seasonal Arctic sea ice
[1] There is an ongoing shift in the Arctic sea ice cover from multiyear ice to seasonal ice. Here we examine the impact of this shift on sea ice albedo. Our analysis of observations from four years of field experiments indicates that seasonal ice undergoes an albedo evolution with seven phases; cold snow, melting snow, pond formation, pond drainage, pond evolution, open water, and freezeup. On...
متن کاملRapid reduction of Arctic perennial sea ice
[1] The extent of Arctic perennial sea ice, the year-round ice cover, was significantly reduced between March 2005 and March 2007 by 1.08 10 km, a 23% loss from 4.69 10 km to 3.61 10 km, as observed by the QuikSCAT/SeaWinds satellite scatterometer (QSCAT). Moreover, the buoy-based Drift-Age Model (DM) provided long-term trends in Arctic sea-ice age since the 1950s. Perennial-ice extent loss in ...
متن کاملAlgal ice-binding proteins change the structure of sea ice.
Krembs et al. (1) reported that extracellular polymeric substances (EPS) produced by a sea ice diatom, Melosira, created convoluted ice-pore morphologies in sea ice, potentially increasing its habitability and primary productivity. The activity was reduced by heat treatment and glycosidase treatments, suggesting that a glycoprotein was involved. Based on our previous work (2), it is very likely...
