Markus Rex led the MOSAiC-Expedition , the largest Arctic research expedition of our time, during which the research vessel “Polarstern” was frozen in the Arctic ice for a year to study the effects of climate [...] climate change. Scientists from 20 nations collected valuable data about the Arctic, which is crucial for understanding the future climate change. In the SR3 podcast “Aus dem Leben”, Markus Rex reports on his [...] findings of this unique mission. The data obtained provides important insights into the dynamics of the Arctic climate and its global impact. SR3 Podcast: Die größte Arktis-Mission aller Zeiten Christian Haas

Data from a recent Arctic expedition reveals large gradients in ocean surface temperature [...] understanding of meltwater spreading and ocean mixing during summertime.
