On 26 August 2026, the Polarstern achieved an impressive milestone: the German research icebreaker has covered a full two million nautical miles since it entered service on 9 December 1982. Of course, the ship’s crew of around 40 people is always on board, ensuring reliable operations at all times. Up to 55 researchers, working in international teams, investigate processes ranging from the seabed through the water column and all the way through to sea ice and up to the atmosphere.
