Every summer, part of the Arctic sea ice melts away, and the melting season is becoming longer. Since the end of the last century, the area covered by ice at the end of summer has gradually decreased, and today, the area is less than half of what it was at the end of the 1970s. To study the arrival of spring in the Arctic – when it comes and how it happens – this year's research expedition with the icebreaker Oden is being carried out earlier than usual.
