Welcome to the CAWS!
Our research group studies impacts of disturbances and land management practices on catchment and wetland functions. We have a strong focus on northern peatlands and peatland-rich catchments, with current research conducted on the Boreal and Taiga Plains of western Canada. Here we study topics related to greenhouse gas fluxes, water quality, soil biogeochemistry, terrestrial-aquatic linkages, hydrogeology, permafrost thaw, wildfire, thermokarst, and soil carbon storage.
