Combined Arctic ice observations show decades of loss

Posted by External 13 hours ago General
http://www.enn.com — It's no surprise that Arctic sea ice is thinning. What is new is just how long, how steadily, and how much it has declined. University of Washington researchers compiled modern and historic measurements to get a full picture of how Arctic sea ice thickness has changed. The results, published this month in The Cryosphere, show a thinning in the central Arctic Ocean of 65 percent between 1975 Read More

Submarine data used to investigate turbulence beneath Arctic ice

Posted by External 4 days ago General
http://feeds.sciencedaily.com — Using recently released Royal Navy submarine data, researchers have investigated the nature of turbulence in the ocean beneath the Arctic sea-ice. Recent decreases in Arctic sea ice may have a big impact on the circulation, chemistry and biology of the Arctic Ocean, due to ice-free waters becoming more turbulent. By revealing more about how these turbulent motions distribute energy within the oce Read More

Harsh winter in Eastern US result of warming Arctic and shifting jet stream

Posted by External 13 days ago General
http://www.enn.com — Prolonged cold snaps on the East Coast, California drought and frozen mornings in the South all have something in common – the atmospheric jet stream which transports weather systems that’s  taken to meandering all over North America.Rutgers University climate scientist Jennifer Francis and colleagues link that wavy jet stream to a warming Arctic, where climate changes near the top of the wo Read More

Methane seepage from Arctic seabed occurring for millions of years

Posted by External 24 days ago General
http://feeds.sciencedaily.com — Natural seepage of methane offshore the Arctic archipelago Svalbard has been occurring periodically for at least 2.7 million years. Major events of methane emissions happened at least twice during this period, according to a new study. Read More

Erratic as normal: Arctic sea ice loss expected to be bumpy in the short term

Posted by External 34 days ago General
http://feeds.sciencedaily.com — Arctic sea ice extent plunged precipitously from 2001 to 2007, then barely budged between 2007 and 2013. Even in a warming world, researchers should expect such unusual periods of no change -- and rapid change -- at the world's northern reaches, according to a new paper. Read More

Arctic Ice Slides into the Ocean

Posted by External 39 days ago General
http://www.enn.com — Satellite images have revealed that a remote Arctic ice cap has thinned by more than 50 metres since 2012 – about one sixth of its original thickness – and that it is now flowing 25 times faster. A team led by scientists from the Centre for Polar Observation and Modelling (CPOM) at the University of Leeds combined observations from eight satellite missions, including Sentinel-1A and CryoSat, Read More

Arctic ice cap slides into the ocean

Posted by External 39 days ago General
http://feeds.sciencedaily.com — Satellite images have revealed that a remote Arctic ice cap has thinned by more than 50 metres since 2012 -- about one sixth of its original thickness -- and that it is now flowing 25 times faster. The findings show that over the last two decades, ice loss from the south-east region of Austfonna, located in the Svalbard archipelago, has increased significantly. In this time, ice flow has accelera Read More
