The region's ice cover is now significantly lower than expected, says the Canadian Ice Service, with coverage on July 30th estimated at 33 per cent, compared to the 1981-2010 median of 79 per cent. Despite the melt, this part of the North-West passage may not yet be navigable.
Melting will continue as we head towards September, when annual ice cover is at its lowest.
At the current rate, 2012 is likely to see the greatest ice shrinkage since satellite records began, exceeding 2007's record low.
