The high sensitivity of Arctic freshwater systems to climate change has kindled a growing impetus to better understand biogeochemical responses to shifts in environmental conditions. For instance, permafrost thaw, changing precipitation regimes, and glacier ice mass loss are major physical changes that implicate hydrologic conditions and the relationship between terrigenous and aquatic systems across the arctic and sub-arctic. Further, there remains much uncertainty as to how these changes will influence the mobility and cycling of carbon in these dynamic systems. The goal of this session is to highlight research that focuses on how carbon cycling is responding to changes in the North. We invite talks that look at the interplay between different carbon pools (i.e. dissolved, particulate, gaseous; organic and inorganic) and that use various tools (characterization methods, stable or radioactive isotopes) to interpret biogeochemical processes and carbon flux or fate in these systems.
