Behaviour of Tritium and Tritiogenic Helium in Freshwater Lens Groundwater Systems: Insights from Langeoog Island, Germany

Figure 7

(a) Apparent age (solid lines) and chloride concentration (dashed lines) for simulations A1 and A2 and (b) the ³H (solid lines) and ³He (dashed lines) concentration versus elevation at the end of the simulation period (31 December 2013). The location of this profile is indicated in Figure 5. Results are shown both for a constant ³H input of 9 TU (as indicated by the subscript c) and for the ³H input according to the curve in Figure 2(b).
