... into sufficiently small floe sizes. Additionally, the ice drift heading varies constantly, with frequent changes of 180 degrees or more in a few hours, which challenges the fleet's ability to maintain the protected vessel within the managed ice channel created by icebreakers working updrift in the moving ice...
