Ice is more than three meters (10 ft) thick on average.
Despite “climate change,” sea ice in the Northwest Passage (NWP) remains too thick and treacherous for it to be a regular commercial Arctic shipping route for many decades, according to new research out of York University.
The feasibility of commercial shipping in the Northwest Passage has attracted a lot of attention lately. However, very little ice thickness information actually exists. This study made the first ever airborne electromagnetic ice thickness surveys over the NWP in April and May 2011 and 2015 over first-year and multiyear ice.
The surveys found a modal thickness of 1.8 to two meters (6 ft to 6′-6″) in most regions of the NWP and mean thickness of between two and three meters (6′-6″ to 10 ft).
Ice originating from the Arctic Ocean showed a mean thickness of more than three meters (10 ft) on average.
Some multiyear ice regions contained much thicker, deformed ice that was more than 100 m wide and more than four meters (13 ft) thick.

“Woe, woe and thrice woe!” says Don. “After all the predictions made by ’emminent, respected’ scientists and nobodies i.e. the UN, how could they have got it so wrong??”
