Arctic permafrost stores massive amounts of organic carbon in its frozen soils and deeper deposits. However, as the Arctic warms particularly rapidly, these deposits are thawing out. As a result, more [...] gases will be released into the atmosphere. There has been little research on where and how quickly permafrost thaws, as well as on the processes that cause the rapid thaw. PeTCaT (Rapid Pe rmafrost T haw Ca [...] to make projections about the possible developments and impacts of greenhouse gases from thawing permafrost. The project is funded by the non-profit organisation Schmidt Sciences.

ILLUQ Permafrost underlies 22% of the Northern Hemisphere's exposed land surface and is thawing at an alarming rate as a direct consequence of climate change. When thawing, permafrost releases large quantities [...] quantities of organic matter and contaminants into the environment. In addition, permafrost thaw dramatically impacts infrastructure in local communities with wide-ranging consequences for health, economy [...] participatory research with local stake- and rightsholders, it will provide the first holistic look at permafrost thaw, pollution and human and environmental well-being in the Arctic and deliver information on

water and sediment samples. Correlations between permafrost distribution and sediment characteristics will help determine the role of subsea permafrost in ecosystem dynamics. Furthermore, the project will [...] this project is to determine the impact of changing land-ocean matter fluxes and coastal subsea permafrost on nearshore ecosystems and biodiversity in the Beaufort Sea. This project will build on recent [...] zone, focusing on how it is impacted by climate change. Investigate the role of recently submerged permafrost in sediment-water gas exchange. In this project, we plan to conduct two campaigns in the spring
