H43F:
Coupled Biogeochemical and Hydrological Processes in Permafrost-Affected Landscapes II Posters

Submit an Abstract to this Session



Session ID#: 29401

Session Description:
The strong coupling between biogeochemical processes and hydrological flow and transport in permafrost environments is an important consideration for developing an integrated understanding of carbon and nutrient turnover and mobilization (including hydrologically driven imports and exports). Disturbances such as permafrost degradation and wildfire make an integrated understanding even more necessary, because disturbance can impose strong feedbacks between biogeochemical, hydrological, geomorphological, and plant processes. This session intends to bring together researchers involved with biogeochemical and hydrological studies in permafrost-affected systems to examine the breadth of critical zone function and to explore how coupled processes control spatial- and temporal-variability from micro-topographic to watershed scales. Studies that examine how hydrological flow and transport characteristics affect biogeochemical cycling are especially welcome.
