Karen Wiltshire’s research focuses on e.g. the ecosystems of the North Sea and Wadden Sea, and the permafrost coasts of Siberia. Furthermore, she coordinates Helgoland & Sylt Roads, one of Europe’s most important

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

ten times that of the equator. Thawing permafrost Two-thirds of Arctic coasts are not rock, but rather permanently frozen soft soil – better known as “permafrost”. Approximately half of the Earth´s carbon [...] carbon are stored underground, and this is mainly contained in the permafrost soils of the northern hemisphere. When permafrost thaws, also as a result of climate change, car- bon dioxide and methane are [...] for example submarine permafrost. Rising wa- ter temperatures could also cause this ice mass to thaw. In the western Laptev Sea in Siberia, for instance, the submarine permafrost currently has a temperature

framework of the International Continental Scientific Drilling Program ( ICDP ). In autumn 2008, a permafrost borehole was drilled next to the western shore of the lake, and in spring 2009, we drilled from

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

One of the very important achievements of the permafrost research group is the [...] Overall, the quality of AWI’s ocean research is excellent. A significant fraction of research on permafrost is conducted at the Potsdam division of AWI, and the group is ranked as the first in Europe and [...] when it comes to research methods, for example in observing greenhouse gas emissions from thawing permafrost.
