Dear Isogeochem,

Please consider submitting an abstract to our session B045: Interactions between hydrological and biogeochemical change in permafrost environments<https://agu.confex.com/agu/fm21/prelim.cgi/Session/118956>
Interactions between hydrological and biogeochemical change in permafrost environments<https://agu.confex.com/agu/fm21/prelim.cgi/Session/118956> at the 2021 AGU Fall Meeting (13- 17 December in New Orleans, Louisiana, USA: and online everywhere). We have had excellent isotope focused contributions to the session over the past few years, and I hope to see more this year.

Best wishes,

Peter

Session Description: As the poles warm, permafrost in high-latitude environments is thawing rapidly. Permafrost thaw activates surface and subsurface hydrologic systems and biogeochemical processes, leading to pronounced impacts on ecosystems and climate on regional to global scales. However, the interactions between thaw-driven hydrological activation and biogeochemical cycling and the resulting feedbacks remain poorly characterized. Our goal is to convene hydrologists and biogeochemists working in permafrost environments to discuss new research linking these two research fields. We welcome studies from different environments, including terrestrial, freshwater, and marine ecosystems, and at scales ranging from studies examining individual organisms, ecosystems, or catchments, to modeling or upscaling studies of large-scale patterns of hydrological and biogeochemical change. We are especially interested in studies that address the role of changing groundwater and surface water flow regimes and how they affect the transport and metabolism of carbon, including greenhouse gas emissions, and nutrients in both subsurface and surface ecosystems.
