Profile submarine permafrost (Foto: Volker Rachold /AWI) (Photo: Alfred Wegener Institut) What is submarine permafrost? Subsea permafrost in the Arctic is generally relict terrestrial permafrost, inundated after [...] Why is it important? Submarine permafrost is similar to its terrestrial counterpart, but lies beneath the coastal seas. And as with terrestrial permafrost, subsea permafrost is a substantial reservoir and/or [...] of submarine permafrost and the influence of future climate system changes on submarine permafrost. Key lines of inquiry include: seasonal and interannual variability of sea floor permafrost boundary conditions
simulation of erosion and mass wasting processes in permafrost landscapes under a warming climate. Current land surface models used to simulate permafrost dynamics are not capable to represent soil erosion [...] between erosion-induced landscape changes and permafrost degradation? In order to answer these crucial questions we will extend and improve the permafrost model CryoGrid3 developed by the Alfred Wegener [...] Background Impacts of permafrost degradation (Graphic: Alfred-Wegener-Institut) Almost a quarter of the land surface of the northern hemisphere of the earth is characterized by permanently frozen soils
Outreach Lesson Plan "Permafrost in the Arctic" The lesson plan “Permafrost in the Arctic” explores the subject of degrading permafrost and its effects on men and environment from different spatial and [...] 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 teaching material [...] investigate current permafrost research topics or explore the conflict of interests of different Arctic stakeholders. Lesson Plan Permafrost in the Arctic Living in the wild North The Permafrost Risk The Ocean
pathways, we are making permafrost visible. Permafrost Change What are the effects of a warmer climate on permafrost? The sound of data Art and Science, an enhancing connection. Permafrost Resources A compilation [...] Why does permafrost matter? illustration of permafrost thaw and climate change during the Long Night of Sciences (Photo: Alfred-Wegener-Institut) Currently we see glaciers melting and observe how sea ice [...] mostly unrecognized. Creating awareness for the processes of permafrost thaw, is our motivation. We want to show what happens, when permafrost thaws - what it means to ecosystems and people living in the

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
further develop the CryoGrid permafrost model and apply it to thermokarst processes in ice-rich permafrost. He also deals with the question of the extent to which the permafrost region in the northern hemisphere [...] help provide a more realistic picture of permafrost thawing. AWI press release original press release Paper entitled "Sensitivity of ecosystem-protected permafrost under changing boreal forest structures [...] the workshop were the impacts of rapid permafrost degradation to the infrastructure and the results, potentials, objectives and plans on modelling of permafrost processes.

December 2018 Loeka, Clara and Josefine take part in the 10th meeting of the working group permafrost oft he [...] embarked on a long and successful journey to better understand and quantify the role of permafrost carbon and rapid permafrost thaw for the carbon cycle. We thank all who contributed to this effort! Many important
Warming permafrost thaws and degrades. Greenhouse gases (GHGs) trapped within or beneath permafrost are released, thus influencing regional and global climate. The carbon cycle of permafrost regions has [...] indicate submarine permafrost thaw. Siberian land craters are a previously unknown permafrost landscape feature. They is evidence of extremely rapid gas release due to permafrost thaw events. Project [...] events on the status of our hydrologic, ecological and socio-economic Earth systems.
