Schematic of the annual catchment C budget for the studied year. This schematic (unscaled) includes the forest NEE and the lateral and downstream CO2 and DOC export and stream CO2 emissions, along with their cumulative annual 14C contents represented by the sizes of the spheres (blue (14C-CO2) and orange (14C-DOC)), at the three locations along the Upslope-Riparian-Stream transect, and depth (shallow [0–0.5 m] and deep [0.5–1 m]). Annual C export rates (g C m−2 yr−1) are written in italic on the left side of each sphere, while the 14C contents are written on the right side
