From Antarctica to the Arctic; from polar caps, permafrost and glaciers to ocean-rafted sea ice; and from burly bears to cold-loving microbes, fascinating science is found in every nook and crevasse of Earth’s cryosphere, and new findings are announced often. Here are a few of the latest updates.
The Bering Sea is a highly productive region of the Pacific Arctic. Native Alaskan communities rely heavily on the marine resources of the Bering Sea for survival. The timing of the formation and thaw of sea ice each year has a significant impact on the structure of the Bering Sea ecosystem. In its current state, […]
With Arctic sea ice disappearing, can advanced sensor technologies provide insights into an ecosystem on the brink? Few things are more important to polar bears than ice, which provides the Arctic carnivores with food, migration routes, and places to bear their young. Show More Summary
Four feet of ice sits atop the Chukchi Sea, several miles from Point Barrow, Alaska. On top, polar bears gambol and walruses loll. What happens beneath the sheet is far more mysterious. To investigate the goings-on in this underwater...Show More Summary

CALGARY, Alberta (Reuters) - Arctic sea ice may be thinning faster than predicted because salty snow on the surface of the ice skews the accuracy of satellite measurements, a new study from the University of Calgary said on Tuesday.
The doings of creatures under the Arctic sea ice are many, but they are rarely observed by humans; it's pretty hard to get under the ice to look. In recent years, marine biologist Andy Juhl and his colleagues have gotten around thisShow More Summary
A University of Manitoba graduate student discovered Canada's first, genuine, scientifically sound monster lurking under our Arctic sea ice.
A study found that more ice formed in the Arctic in 2017 than in all but four of the last 37 years, challenging the recent media narrative that the earth is warming and seas are rising because of manmade activity. Instead of reporting this study, media outlets focused on another report that more closely matched […]
Climate changes are pronounced in Arctic regions and increase the vulnerability of the Arctic coastal zone. For example, increases in melting of the Greenland Ice Sheet and reductions in sea ice and permafrost distribution are likely to alter coastal morphodynamics. Show More Summary
The Trump administration announced Wednesday it will not list the Pacific walrus as a threatened species based on diminished Arctic Ocean sea ice, concluding that the marine mammals have adapted to the loss.

The Arctic Ocean hasn’t always been as salty as other oceans. In the Eocene, between 56 million and 34 million years ago, the water surrounding the North Pole — freshened by melt from sea ice and river runoff — was cut off from the Atlantic and Pacific oceans by land bridges. Show More Summary
Arctic sea ice appeared to have reached its yearly lowest extent on Sept. 13, NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder have reported. Analysis of satellite data by NSIDC...Show More Summary
Scientists calculate that Arctic sea ice this summer dropped to its eighth lowest level on record. That's far below average, but considerably above the record low set five years ago. … Click to Continue »

ANCHORAGE, Alaska (AP) — An environmental activist is calling on the U.S. Fish and Wildlife Service to reconsider placing anchored rafts in the ocean as resting platforms for walruses after stampedes killed 64 animals on Alaska's northwest coast.
The extent of Arctic sea ice is an important marker for global climate change. In the last forty years it also has been unequivocally shrinking. NASA has been tracking Arctic sea ice extent at different times of the year, with the September minimum being an important point of comparison. Like any chaotic system there are […]
(Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research) This September, the extent of Arctic sea ice shrank to roughly 4.7 million square kilometres, as was determined by researchers at the Alfred Wegener Institute, the University of Bremen and Universität Hamburg.
