like what we now see in eastern Siberia. Today’s Arctic, with ice-covered Greenland, Siberian permafrost and sea ice at the North Pole, is a holdover of that glacial world. But for how much longer? As

large-scale components of the Earth, like the ice sheets and ocean circulation, boreal forest and permafrost. We strive to increase our understanding of the relevant processes driving dynamics within these

When we take samples from the permafrost today and analyse the isotope ratio of the ground ice in our laboratory, we also make this fingerprint [...] Environmental Systems Past Climate Change ISOLAB Facility - Stable Isotope Laboratory Potsdam Permafrost research at the AWI Glaciological research at the AWI Sample preparation: it couldn't be cleaner
