Sea ice which has become honeycombed and is in an advanced state of disintegration. Sastrugi, (sing. sastruga). Sharp, irregular ridges formed on a snow surface by wind erosion and deposition. On mobile floating ice, the ridges are parallel to the direction of the prevailing wind at the time they were formed. Sea ice. Any form of ice found at ...

2021年1月2日 · Bering Sea Even though the Chukchi finally ended up freezing over pretty much on schedule, the Bering Sea seems to continue its progress to being a mostly ice-free sea even in winter. NSIDC- Central Arctic Extent.png (73.1 kB, 824x601 - viewed 100 times.)
The Many Forms and Shapes of Ice
Glacier ice is formed from compacted snow. Thus, they are composed entirely of fresh water. Antarctica, Greenland, and parts of Canada have glaciers. The Antarctic ice sheets are the largest, containing 85% of the world’s ice. Where glaciers meet the sea, the ice can flow out onto the ice, forming a thick, floating ice shelf.

2017年1月5日 · Banks Island is one of 36,563 ice-covered islands sprinkled in the Arctic Ocean north of Canada. It is home to the world’s largest population of muskoxen—about 68,000—one tiny village with a population of slightly more than 100 people, and an airport, which during the spring and summer of 2014 bustled with researchers poised to jump into the vast white Arctic.
Melting Ice Threatens Polar Bears’ Survival
2008年1月23日 · The colors range from dark blue (ice free) to white (100 percent sea ice covered). (Courtesy of NOAA) Mathematical ecologists Hal Caswell of WHOI (above) and Christine Hunter of the University of Alaska developed new population dynamics models that documneted for the first time the critical importance of sea ice for polar bears' survival.

2022年9月19日 · When that ice melts, the total volume of water remains unchanged. But as glaciers and ice sheets on land melt, the water they contain flows out to sea, adding to the total volume of water in the ocean. “About two-thirds of the global-mean sea-level rise we’ve seen since the early nineties is due to melting of land ice,” Piecuch notes.
