Permafrost
How is climate change affecting the permanently frozen soils of the Arctic? What will the consequences be for the global climate, human beings, and ecosystems? And what can be done to stop [...] an AWI group led by Moritz Langer has now created an interactive map of the past and future of permafrost. Both publications arrive at the same conclusion: to put a stop to the dangerous trends in these

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

glaciers and sea ice, can be observed directly, most of the permafrost’s melting takes place deep below the surface. However, since the permafrost stores huge quantities of carbon, which is released in the [...] thawing will further worsen global warming. In order to collect reliable, up-to-date information on permafrost thawing, the joint project UndercoverEisAgenten was launched today.
