A warm region of water trapped deep below the surface of the Arctic seas north of Canada has the potential to leave the entire area devoid of ice. Scientists have discovered warmer water that originated hundreds of miles away has penetrated deep below the ice pack’s surface. Vast swathes of the polar expanse are changing dramatically every year – with sea ice vanishing far earlier in the season that it used to, and ships beginning to take advantage of the newly ice-free oceans. This effect could be exacerbated in one of the Arctic Ocean’s major regions – known as the Canadian Basin – by the influx of warmer water that is currently stored underneath it. Using data collected over the past 30 years, researchers at Yale University and Woods Hole Oceanographic Institution saw the “heat content” of the area had doubled during this period.
