(δ13CCH4 about −50 ± 5‰; Fisher et al., 2011, 2017; France et al., 2016). This region also hosts permafrost and gas hydrates, though emissions from gas hydrates and seeps currently seem to be lower than

Permafrost
Arctic coasts are characterized by sea ice, permafrost and ground ice. This makes them particularly vulnerable to the effects of climate change, which is already accelerating rapid coastal

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

Permafrost Thaw Action Group The Permafrost Thaw Action Group was part of the Terrestrial Multidisciplinary distributed Observatories for the Study of Arctic Connections (T-MOSAiC). Together with MOSAiC [...] d collection of field data for quantifying permafrost thaw. It addresses the need for integrated observations of multiple connected components of permafrost landscapes, including soils, snow, and vegetation [...] vegetation. Illustration of the standarized permafrost monitoring protocol. The five spheres (snow, water, permafrost, vegetation and soil) with the associated parameters, measurement modes, and observation

New Study
As a result of global warming, permafrost regions around the world are thawing now. As they do, climate-relevant greenhouse gases containing carbon (carbon dioxide, methane) and nitrogen (nitrous [...] climate forecasts. Whereas substantial research has been conducted on the carbon reservoirs in permafrost, we still know comparatively little about nitrogen. A team of experts led by the Alfred Wegener

By the end of this century, permafrost in the rapidly warming Arctic will likely emit as much carbon dioxide and methane into the atmosphere as a large industrial nation, and potentially more than the U.S. has emitted since the start of the industrial revolution. More information on the findings of an international team inculding scientists from the Alfred Wegener Institute can be found in this press release by the Northern Arizona University...

This can dramatically change the landscapes and water cycle in permafrost regions, while also affecting

Canada, near the communities of Inuvik and Tuktoyaktuk. Our goal is to study the current state of permafrost as part of the MOSES (Modular Observation Solutions for Earth Systems) project. Our research in [...] “Lake 3” we conducted Electrical Resistivity Tomography surveys in an effort to map the depth to permafrost under the lake. As part of our outreach activities, some members of our team joined a summer camp
