Methane seeps in the Canadian high Arctic
Apr 20, 2017 (SPX)
Seep mounds are carbonate deposits, often hosting unique fauna, which form at sites of methane leakage into the seafloor. Over 130 were found covering over 10,0...
Arctic river ice deposits rapidly disappearing
Apr 20, 2017 (SPX)
In the past, river icings have melted out around mid-July, on average. But a new study measuring the extent of river icings in the U.S. and Canadian Arctic show...
How polar bears find their prey
Apr 20, 2017 (SPX)
Using satellite telemetry data collected from 123 adult polar bears in Canada's Hudson Bay over 11 years, the researchers merged the movements of polar bears wi...
Glacier shape influences susceptibility to melting
Apr 19, 2017 (SPX)
"There are glaciers that popped up in our study that flew under the radar until now," said lead author Denis Felikson, a graduate research assistant at The Univ...
Russia reveals virtual tour of new Arctic military base
Apr 18, 2017 (UPI)
The tour, presented on the defense ministry's website, allows visitors to browse through various structures of the base. It does not depict or discuss any milit...
Researchers unravel the drivers of large iceberg movement
Apr 13, 2017 (SPX)
The researchers have now succeeded in modelling how Antarctic icebergs drift through the Southern Ocean, and in identifying the physical factors behind their mo...
Warm Atlantic waters contribute to sea ice decline
Apr 13, 2017 (SPX)
Research led by Igor Polyakov, a professor at UAF's International Arctic Research Center and College of Natural Science and Mathematics, has found that Atlantic...
Polar glaciers may be home to previously undiscovered carbon cycle
Apr 13, 2017 (SPX)
The cycle, they argue, could become a significant global source of carbon as temperatures rise worldwide and microbial activity increases. An international team...
Ancient poo shows Antarctic penguins' volcanic past
Apr 12, 2017 (AFP)
Analysis of ancient penguin guano has revealed that volcanic eruptions, not climate change, almost wiped out an Antarctic sea bird colony three times, researche...
Researchers ask public to help them count Weddell seals
Apr 10, 2017 (UPI)

Climate seesaw at the end of the last glacial phase
Apr 04, 2017 (SPX)
The climate of the Earth follows a complex interplay of cause-and-effect chains. A change in precipitation at one location may be caused by changes on the other...
Microbial colonizers of Arctic soils are sensitive to future climate change
Apr 04, 2017 (SPX)
A team of researchers from the University of Bristol have recently shown that ecosystems created by melting glaciers in the Arctic are sensitive to climate chan...
Some of Greenland's coastal ice will be permanently lost by 2100
Apr 04, 2017 (SPX)
The glaciers and ice caps that dot the edges of the Greenland coast are not likely to recover from the melting they are experiencing now, a study has found. Res...
Microbes on ice sheets produce bioreactive carbon that is exported to downstream ecosystems
Apr 04, 2017 (SPX)
Glaciers and ice sheets have recently been considered significant sources of organic carbon and provide nutrients to downstream marine ecosystems. However, the ...
1997 was 'tipping point' for ice caps around Greenland's edges
Apr 04, 2017 (SPX)
Measuring almost 100,000 km2 (about twice the size of the Netherlands), the ice caps around Greenland's edges represent the largest glacierised area on earth, o...
Solving the mystery of the Arctic's green ice
Apr 02, 2017 (SPX)
