human activity in the Arctic takes place along permafrost coasts. These coasts have become one of the most dynamic ecosystems on Earth because permafrost thaw is now exposing them to rapid change: change [...] fates of organic matter released from thawing coastal and subsea permafrost; (2) assess what risks are posed by thawing coastal permafrost, to infrastructure, indigenous and local communities and people’s [...] system. NUNATARYUK is a H2020 project that investigates the impacts of thawing coastal and subsea permafrost on the global climate, and develops targeted and co-designed adaptation and mitigation strategies

The relative importance of these controls on the rate of sub-aquatic permafrost degradation, however, remains poorly understood. Therefore, the overarching science goal for the [...] the 2017 Bykovsky Spring Expedition was to evaluate the nature and distribution of subaquatic permafrost and taliks in multiple cryostratigraphic settings with drilling, sampling, near-surface geophysics

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

trace gases from thawing permafrost. The weather in Brandenburg also fluctuates due to long-range atmospheric effects from the Arctic. 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
