Figure 1

Measured ³⁶Cl/Cl (unitless) (a), ³⁶Cl (b) and Cl (c) stocks (bars, at m⁻²), water (blue dots) and litterfall (green dots) fluxes (at m⁻² year⁻¹). These fluxes were derived from measurements made in water (rainfall, throughfall—that is the water collected below the forest canopy—and soil water drainage at 60 cm depth) in 2012–2013, and stocks from soil sampled in 2010 along a soil depth profile at Montiers, France. Colours for the different soil stocks represent the different soil layers.
