Permafrost Modelling Profile Why do we need Permafrost Models? Permafrost models are important tools to investigate the role and the sensitivity of frozen ground under very complex environmental and climatic [...] Since permafrost is usually not visible at the earth’s surface and only few measurement sites exist, models are also important to investigate the current state of permafrost. Furthermore, permafrost models [...] the elements that we are able to simulate with our permafrost-land surface model. (Graphic: Alfred-Wegener-Institut) What are Permafrost Models? Permafrost models provide information on ground temperatures

Permafrost Remote Sensing Profile Permafrost landscape dynamics are intensifying in rapidly warming Arctic-Boreal high northern latitude regions. Relying on field studies we observed and understand a wide [...] continuous time series data of land cover change, permafrost landscape change, or other environmental dynamics. We particularly focus on permafrost region landscape characteristics, land cover change [...] Friedrich Röseler Annabeth McCall Carl Stadie Guest: Kathrin Maier Projects FLO CHAR ESA Permafrost CCI ESA GlobPermafrost ERC PETA-CARB (2013-2018) IPA Action Group - The Yedoma Region

Coastal Permafrost Profile About 34% of the world's coasts are affected by Arctic permafrost and are particularly sensitive to climate change. The frozen cliffs lose their cohesion, which is ensured by [...] ble to quantify the amount of eroded sediment and organic material more accurately. The group "Permafrost Coasts" investigates the velocity and character of sediment and organic matter transport into the [...] echosounder bathymetry: to quantify the content of particulate and dissolved organic material in permafrost sediments and their bottom ice and to characterize its spatial variability; to quantify the velocity

inducing more permafrost thaw and carbon release. To assess the concern of a permafrost-climate feedback and to develop a better understanding of future permafrost-carbon dynamics, the Permafrost Biogeochemistry [...] drastic changes in Arctic permafrost landscapes, such as active layer deepening, thermal erosion and development of rapid thaw features. Organic matter stored frozen in permafrost deposits for thousands of [...] Characterizing the past, present and future changes of permafrost organic matter under warming climate and changing land use. Mission Statement: The Permafrost Biogeochemistry Working Group focuses its efforts

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

the permafrost – with a host of grave consequences. Typical permafrost landscape in Yukon, Canada (Photo: Alfred-Wegener-Institut) What does permafrost look like? Some landscapes in the permafrost regions [...] Can permafrost only be found on land? How deep does the permafrost go? To what depth does it thaw in summer? Why is thawing permafrost important for the climate? How much carbon does the permafrost contain [...] How fast is the permafrost thawing? Why are permafrost coasts increasingly collapsing? How is the thawing permafrost affecting people living in these regions? How is the thawing permafrost affecting economies

Permafrost Region Greenhouse Gases Profile Climate change affects many northern ecosystems such as wetlands, peatlands and permafrost soils, which store a lot of carbon and nitrogen in organic matter. [...] peatlands, wetlands, and permafrost soils. Our projects focus on carbon and nitrogen interactions, cold-season biogeochemical processes, methane emissions from northern wetlands, and permafrost dynamics in northern [...] published a paper with the title: Predicted vulnerability of carbon in permafrost peatlands with future climate change and permafrost thaw in Western Canada doi.org/10.1029/2020JG005872 12 March
