Data from: Sea ice choke points reduce the length of the shipping season in the Northwest Passage
Arctic sea ice has shifted from a perennial (older, thicker ice) to a seasonal (younger, thinner) ice regime, leading to the increasingly common belief that shipping through Canada's Northwest Passage is becoming more viable. Here, we use the Risk Index Outcome values derived from the Polar Ope...

Arctic sea ice has shifted from a perennial (older, thicker ice) to a seasonal (younger, thinner) ice regime, leading to the increasingly common belief that shipping through Canada's Northwest Passage is becoming more viable.
