This talk is about my first hand experience overwintering onboard RV Polarstern in the Central Arctic Ocean. In fall 2019 the largest Arctic research expedition set out to be trapped in the ice for an entire year to fill the data gaps. The MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) campaign onboard the German icebreaker POLARSTERN drifted across the Central Arctic Ocean so an international team from 20 countries could study atmospheric processes, ice and ocean physics, biogeochemical cycles and ecosystem changes. The winter leg from November to March was defined by low temperatures and constant darkness but also by lead openings and buildup of pressure ridges, demonstrating that the “New Arctic” is not just a concept anymore but that it is already a reality.
