We invite you to submit an abstract to our session "Molecular Biomarkers in Polar Regions and the Cryosphere" (ID: 103071) for the AGU Fall Meeting 2020. This session highlights organic biomarker research contributing to a growing understanding of the vulnerable and rapidly changing polar regions and cryosphere. We encourage contributions from research on terrestrial, marine and freshwater ecosystems in Arctic, Antarctic and alpine regions. For the full description, see below.
The deadline for abstract submission is the 29th of July 2020. Here you find the link to the session: https://agu.confex.com/agu/fm20/gateway.cgi/Session/103071
Please contact us if you have any questions (loeka.jongejans@awi.de)

Session description: Polar regions are changing rapidly. As a result, increased fluxes of sediments, carbon and nutrients from terrestrial to marine and freshwater environments will impact geochemical, microbial and ecological processes. The magnitude and duration of these impacts are still poorly understood. Concurrently, the permafrost carbon store is becoming increasingly vulnerable to the effects of ongoing permafrost thaw. When permafrost thaws, organic matter (OM) stored for geological time scales in the frozen underground can become bioavailable. Its biodegradability and contribution to the permafrost carbon climate feedback cycle is of utmost interest. The analysis of biomarkers is crucial in the characterization of living and fossil microbial communities and of OM degradation and greenhouse gas production. This session highlights organic biomarker research contributing to a growing understanding of the vulnerable and rapidly changing polar regions and cryosphere. We encourage contributions from research on terrestrial, marine and freshwater ecosystems in Arctic, Antarctic and alpine regions.
