This session will feature a broad variety of research investigating ecosystem processes from a biogeosciences perspective. To showcase a diversity of researchers, submissions from early career researchers (ECRs) are encouraged. Presentations that demonstrate progress towards improved understanding of biogeochemical processes and patterns, and/or advances in models are welcomed. In particular, we encourage presentations that seek to quantify biogeochemical functions of natural or managed environments; characterize measurement and modelling uncertainty in complex and heterogeneous landscapes; scale water/nutrient/element/sediment exchange processes; quantify the impacts of climate and land-use change on water/nutrient/element/sediment fluxes across ecosystems; or identify and evaluate the effects of extreme weather and disturbance phenomena on biogeochemical properties. Studies at local to landscape scales, with a focus on atmospheric, terrestrial, or aquatic systems will all be considered. Please identify ECR presenters in abstracts as we will set aside speaking time specifically for ECRs.

Conveners: Sophie Wilkinson, School of Resource and Environmental Management, Simon Fraser University;  Britt Hall, Department of Biology, University of Regina; Colin Whitfield, School of Environment and Sustainability, University of Saskatchewan; Colin McCarter, Biology and Chemistry, Nipissing University
