Figure 4

Time series of observed (black) and modelled values (red) of dissolved-phase 90Sr concentrations. Orange dots indicate the posterior predictive credible interval (A). The relationship between observed and modelled values of dissolved-phase 90Sr concentrations. The response of dissolved phase 90Sr concentrations to discharges rate for each period are also shown in (C1-3). Red dashed lines in (C) indicate the model result for the middle of each period.
