Dear colleagues, we would like to invite and encourage you to share our session Biogeochemistry of changing permafrost systems at the upcoming EGU General Assembly, from 27 April to 2 May 2025 in Vienna. The deadline for submitting abstracts is the 15th of January 2025. Please find more details about the session below.
We are looking forward to see you in Vienna! Rica Wegner, Birgit Wild, Christian Beer and Georg Guggenberger ---------------------------------------------------------------------------------------------------------------------- BG3.18 Biogeochemistry of changing permafrost systems: Permafrost soils are one of the largest and most vulnerable terrestrial carbon and nitrogen pools. Right now, we observe that global warming is leading to drastic landscape changes and widespread permafrost thaw. Coastal erosion is aggravating, the boreal tree line is shifting northwards, tundra fires are becoming more frequent and the degradation of peatlands with permafrost is increasing. The ongoing increase of temperature will enhance microbial decomposition of long-term stored soil organic matter and might eventually turn permafrost soils into a significant source of greenhouse gases. In addition, the degradation of permafrost increases the export of dissolved organic carbon, nutrients and pollutants into waterbodies impacting primary production and human health. We encourage submissions focusing on organic and inorganic carbon as well as on other elements such as nitrogen, phosphorus, silica, iron, mercury and others, from all parts of the global permafrost area including mountain, inland, coastal and subsea permafrost, on all spatial scales, in the contemporary system but also in the past and future, based on field, laboratory and modelling work.
