It is on the tiny island of Ward Hunt, Canada’s northernmost point of land, that a small aircraft will drop the AKOR crew on the ice floe in early March 2021. At this time of year, the temperature will normally be below -30 degrees Celsius and the sun will shine for only 10 hours a day. At that precise moment, in front of the icy expanse that will impose its heavy Arctic silence, the crew will finally take the human measure of this route so long dreamed and studied.
