The intrepid team of the MOSAiC expedition set off into the Arctic. Their first task, to find a suitable patch of drifting sea ice that will carry them and their research base, close to the North Pole and right across the Arctic. But it won’t be easy. In this first few weeks of their mission, they’ll face brutal cold, cracking ice, hungry polar bears, violent storms and the 24-hour-darkness of Arctic winter. They reveal more about life in Arctic winter than ever before possible and disturbing evidence of our warming oceans.
