Groundwater and stream water 14C-CO2 and 14C-DOC at the transect scale. Catchment schematic (unscaled) illustrating the 14C-CO2 (blue spheres) and 14C -DOC (orange spheres) expressed in %modern. The size of the spheres is proportional to the 14C content and specific values are written on the right side of each sphere. The measurements were made along the Upslope-Riparian-Stream transect, at shallow (0–0.5 m) and deep (0.5–1 m) groundwater depths, in a May 2015, b August 2015, c October 2015. The original 14C data are listed in Supplementary Table 2
