LandScales integrates the aquatic and terrestrial perspectives of landscape carbon dynamics within a multidisciplinary collaborative research environment, by characterising structures, processes, and fluxes across scales. The goal is to characterise carbon sequestration and release in a moraine landscape representative of landscapes of glacial origin. A major point is the scaling of carbon fluxes and underlying mechanisms from the plot to the landscape level by accounting for spatio-temporal heterogeneity of structures and functions, and to address the uncertainties of scaling approaches. These objectives are vital for optimising the C sequestration at the landscape scale and for sustaining an important ecosystem service.
