Forever frozen? Permafrost in the Arctic In story 1 students receive basic knowledge about permafrost and the consequences of climate change for permafrost. The importance of permafrost research is explained [...] changed in the Arctic over the last decades? What is permafrost? How does thawing permafrost affect the Arctic environment? How does thawing permafrost affect Arctic infrastructure? The main goal of this [...] and learn about permafrost in the Arctic and the effect of degrading permafrost on the Arctic environment. The focus lies on the complex interactions between men, nature and permafrost and resulting conflicts

Permafrost
The frozen permafrost in the Arctic is thawing on an alarming scale. By analysing an annual record of satellite images, researchers at the Alfred Wegener Institute have now confirmed these

With warming in the Arctic expected to [...] e the spatial variability of particulate and dissolved organic carbon and nutrient contents in permafrost sediments and ground ice as well their sediment characteristics through cross-shore sampling transects
