The Arctic is warming more than twice as fast as the global average, making climate change’s polar effects more intense than anywhere else in the world. The Arctic accounts for half of the organic carbon stored in soils. There is high confidence that the thaw of terrestrial permafrost will lead to carbon release, but only low confidence regarding timing, magnitude and relative role of different GHG’s according to the sixth assessment report of IPCC (2021).

Therefore, in this session we aim to bring together biogeochemical science in high latitude regions. From small scale processes such as those measured by flux chambers, to site-scale eddy covariance fluxes, to regional scale atmospheric carbon cycle measurements, all the way to pan Arctic monitoring by satellites. We are interested in both measurements of high latitude carbon and nutrient cycles as well as environmental changes.
In this session we encourage abstracts with new findings on high latitude biogeochemical research such as CO2, CH4 or N2O fluxes, but also groundwater nutrient flow or atmospheric concentrations and their sources. We also encourage submissions on environmental change topics such as Arctic greening, wetlands extent change, and permafrost degradation, and ways to map these changes based on remote sensing.

Finally, large-scale high latitude projects such as: AMPAC a transatlantic initiative by NASA and ESA, which brings together a wide range of high latitude CH4 focused activities from Europe as well as North America. But also projects such as ABoVE, Permafrost Pathways, Q-Arctic,. Are welcome.
