Permanent Arctic Ice Vanishing - Satellite Images Misled Shocked Scientists

EDIT

Experts around the world believed the ice was recovering because satellite images showed it expanding. But David Barber says the thick, multi-year frozen sheets crucial to the northern ecosystem have been replaced by thin "rotten" ice that can't support weight of the bears. "It caught us all by surprise because we were expecting there to be multi-year sea ice. The whole world thought it was multi-year sea ice," said Barber, who just returned from an expedition to the Beaufort Sea.

"Unfortunately, what we found was that the multi-year (ice) has all but disappeared. What's left is this remnant, rotten ice."

Permanent ice, which is normally up to 10 metres thick, was easily pierced by the research ship, said Barber, who holds the Canada research chair in Arctic science at the University of Manitoba. The team finally reached what it thought was stable ice, only to watch a crack appear just as researchers were preparing to descend onto the floe.

"As I watched, over the course of five minutes, the entire multi-year ice floe broke up into pieces," Barber said. "This floe was 16 km across. Something that's twice the size of Winnipeg, it just broke up right in front of our eyes."
