Warm water has penetrated the Arctic interior
Aug. 30 (UPI) -- Arctic ice faces a threat from within, according to a new study by researchers at Yale University. Scientists have identified a mass of "archived" heat trapped beneath the Arctic surface. The mass of warm water originated from hundreds of miles away, but has infiltrated the Arctic interior. "We document a striking ocean warming in one of the main basins of the interior Arctic Ocean, the Canadian Basin," Mary-Louise Timmermans, a professor of geology and geophysics at Yale, said in a news release. Over the last three decades, the amount of heat in the Canadian Basin's upper ocean has doubled. Timmermans and her colleagues traced the heat source to waters a few hundred miles south, where sea ice losses have left the surface of the ocean exposed to the summer sun. Arctic win...
