B23C:
Interactions Between Hydrological and Biogeochemical Change in Permafrost Environments I


Submit an Abstract to this Session


Session ID#: 59774

Session Description:
As the poles warm, permafrost in many high-latitude environments is thawing rapidly. Permafrost thaw causes hydrological and biogeochemical feedbacks that can have pronounced impacts on regional and global ecosystems and climate. However, the interactions between hydrology and biogeochemical cycles in permafrost environments remain poorly characterized. Our goal for this session is to convene hydrologists and biogeochemists working in permafrost environments to discuss new research linking these two critical research fields. We welcome studies at a wide range of scales, ranging from process-level studies examining individual organisms, ecosystems, or catchments, to modeling or upscaling studies of the global or regional-scale patterns of hydrological and biogeochemical change. We are especially interested in studies that address the role of changing groundwater flow regimes in permafrost environments and how they affect the transport and metabolism of carbon and nutrients in both subsurface and surface ecosystems.
