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

Coastal permafrost erosion, organic carbon and nutrient release to the arctic nearshore zone (COPER) Permafrost Erosion Arctic permafrost coasts, which account for 34% of the coasts of the Earth, are extremely [...] change, because the frozen bluffs, upon contact with seawater, lose the cohesion provided by the permafrost matrix and are instantly washed away by incoming waves. 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

The north polar seas, coasts and permafrost regions contain unique habitats [...] modular components for cloud observation, analytical and data-based tools for remote sensing in permafrost regions and laboratory equipment for analyzing a wide range of sample series from the atmosphere [...] components of the InnoLab concentrate on the three research fields at the AWI Potsdam in relation to permafrost dynamics , the spatio-temporal variability of polar terrestrial environmental systems and the role

Every particle that is not consumed by marine animals, including [...] not only to reconstruct the Arctic’s climate history, but also to understand the role of thawing permafrost in past climate changes. Based on this knowledge, they can make more accurate predictions about

inundation of coastal permafrost areas and their role in the permafrost carbon climate feedback.
