This session aims to showcase science from early career researchers (ECRs) investigating ecosystem processes from a biogeosciences perspective. Research that demonstrates progress towards an 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 biophysical exchange processes; quantify the impacts of climate and land-use change on ecohydrological 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.
