Arctic Ice: Less Than Meets the Eye

By Chris Mooney | August 28, 2010 1:59 pm

amundsenI have a feature story in the latest issue of New Scientist about the decline of Arctic sea ice, and our expectations for this fall when a seasonal low is reached. Here’s how it starts out:

LAST September, David Barber was on board the Canadian icebreaker CCGS Amundsen, heading into the Beaufort Sea, north of Alaska. He was part of a team investigating ice conditions in autumn, the time when Arctic sea ice shrinks to its smallest extent before starting to grow again as winter sets in.

Barber, an environmental scientist at the University of Manitoba in Winnipeg, Canada, went to sleep one night at midnight, just before the ship was due to reach a region of very thick sea ice. The Amundsen is only capable of breaking solid ice about a metre thick, so according to the ice forecasts for ships, the region should have been impassable.

Yet when Barber woke up early the next morning, the ship was still cruising along almost as fast as usual. Either someone had made a mistake and the ship was headed for catastrophe, or there was something very wrong with the ice, he thought, as he rushed to the bridge in his pyjamas….

Read on to figure out what Barber learned….and how it affects us all going forward.
