Alaskan Polar Bears Threatened

Five meters of ice– about 16 feet thick – is threatening the survival of polar bears in the Southern Beaufort Sea region along Alaska’s Arctic coast, according to Dr. Susan J. Crockford, an evolutionary biologist in British Columbia who has studied polar bears for most of her 35-year career.

 

That’s because the thick ice ridges could prevent ringed seals, the bears’ major prey, from creating breathing holes they need to survive in the frigid waters, Crockford told CNSNews.com.

 

“Prompted by reports of the heaviest sea ice conditions on the East Coast ‘in decades’ and news that ice on the Great Lakes is, for mid-April, the worst it’s been since records began, I took a close look at the ice thickness charts for the Arctic,” Crockford noted in her Polar Bear Science blog on April 18th.
