Permafrost
Throughout the Arctic, ice wedges are thawing at a rapid pace. Changes to these structures, which are very common in permafrost landscapes, have a massive impact on the hydrology of the tundra

Award
Permafrost researcher Dr Jens Strauss, AWI Potsdam, was awarded "Young Scientist 2015". With this award the chairmen of the Friends' Association acknowledge the researcher's outstanding achievements

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. With a unique array of measurement platforms, high-resolution modelling capabilities, and a d

Arctic coasts are characterized by sea ice, permafrost and ground ice. This makes them particularly vulnerable to the effects of climate change, which is already accelerating rapid coastal
