Warm Atlantic waters contribute to sea ice decline
Fairbanks AK (SPX) Apr 13, 2017
A University of Alaska Fairbanks study has determined that warmer water migrating from the Atlantic Ocean is a surprisingly powerful contributor to Arctic sea ice decline. 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 currents contribute to sea ice loss in the Arctic Ocean at a rate comparable to warming air temperatures. "This is a very important step toward a seasonal ice-free ... read more

Searching for polar bears on Alaska's North Slope
On a frigid March day in 2011, workers with ENI Petroleum were busy moving construction equipment on and off Spy Island, a man-made offshore drill site in the Beaufort Sea a few miles off the coast near Ooliktok Point, when a female polar bear popped out of a deep snow drift under the artificial ground. She blinked wearily at her surprised neighbors, sniffed the air, then rolled around in the snow to clean off her white fur after a five-month slumber. In less than 12 hours, the island was shut down and evacuated. ... more
