End-of-summer Arctic sea ice extent is eighth lowest on record

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

Cloudy, cool August restrains melt of Arctic sea ice

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 »

Activist urges walrus rafts in absence of Arctic sea ice

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.

Update on Arctic Sea Ice

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 […]

Arctic sea ice once again shows considerable melting

(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.

Ice (Re)Cap: September 2017

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.

Unraveling a major cause of sea ice retreat in the Arctic Ocean

Ice-covered sea areas in the Arctic Ocean during summer have nearly halved since the 1970s and 1980s, raising alarm that the ocean is shifting from a multiyear to a seasonal ice zone. The Intergovernmental Panel on Climate Change (IPCC) has forecasted summer ice cover in the polar ocean might disappear almost completely as early as 2050. Show More Summary

Unraveling a major cause of sea ice retreat in the Arctic Ocean

(Hokkaido University) Quantitative analysis has evidenced the acceleration system of melting ice: dark water surfaces absorb more heat than white ice surfaces, thus melting ice and making more water surfaces in the Arctic Ocean.

Studies call for expansion and digitization of Arctic museum collections

As sea ice continues to disappear, scientists are rushing to gather data on Arctic taxa. How should the collected plant and animal specimens be stored? As Indigenous communities age, traditional knowledge and cultural history is at risk of being lost. Show More Summary

Record-low 2016 Antarctic sea ice due to 'perfect storm' of tropical, polar conditions

While winter sea ice in the Arctic is declining so dramatically that ships can now navigate those waters without any icebreaker escort, the scene in the Southern Hemisphere is very different. Sea ice area around Antarctica has actually increased slightly in winter—that is, until last year.

NASA scientists seek to improve sea ice predictions

Sea ice in the Arctic Ocean is in a downward spiral, with summer minimum extents about 40 percent smaller than in the 1980s. But predicting how the sea ice is going to behave in a particular year is tricky: There are still many unknowns...Show More Summary

New findings on the past and future of sea ice cover in the Arctic

Temperatures in the Arctic are currently climbing two to three times faster than the global average. The result - and, thanks to feedback effects, also the cause - is dwindling sea ice. In a study published in the actual volume of Nature...Show More Summary

Russian LNG Tanker Crosses Arctic Ocean In Record Time

A specially constructed LNG tanker has set a new record for the time it takes to sail through sea ice in the Arctic Ocean. 14 more of the tankers are planned. Russian LNG Tanker Crosses Arctic Ocean In Record Time was originally published on CleanTechnica.

Warming Arctic spurs battles for riches, shipping routes

From a distance, the northern shores of Baffin Island in the Arctic appear barren—a craggy world of snow-capped peaks and glaciers surrounded by a sea of floating ice even in the midst of summer.

Implications of ocean acidification in the Pacific Arctic: Experimental responses of three Arctic bivalves to decreased pH and food availability

Recent sea ice retreat and seawater warming in the Pacific Arctic are physical changes that are impacting arctic biological communities. Recently, ocean acidification from increases in anthropogenic CO2 has been identified as an additional stressor, particularly to calcifying organisms like bivalves. Show More Summary

Animation Shows Disappearance of Arctic Sea Ice

last monthNews : USAToday: News

Experts say Arctic sea ice is disappearing earlier in summer and returning later in the fall. An AP animation shows how sea ice coverage has dropped an average of 34,000 square miles per year. (Aug. 14)        

Arctic Thaw helps Russian Shipping

Arctic thaw aids shipping most along Russian coast; Russia to start LNG exports from Yamal in late 2017. Russian shipping in the Arctic is benefiting from winds that are driving the oldest and thickest sea ice towards North America, further…
