Biogeosciences underpins many critical ecosystem processes, often working at the intersection of multiple disciplines. This session will highlight the diversity of research investigating ecosystem processes from a biogeoscientific/biogeochemical perspective. We invite a broad range of research contributions from across Canadian biogeosciences that use, but are not limited to, in situ field studies, laboratory experiments, numerical modelling, method/sensor development, remote sensing or other approaches. General topics can, but are not limited to, include biogeochemical function of natural or managed ecosystem, quantifying the impacts of climate and land-use change on water/nutrient/element/sediment fluxes, measuring or modelling the effects of ecological communities on ecosystem dynamics or long-term change, or developing and testing new sensor systems and measurement techniques.
