Figure 3
Response of dissolved-phase 90Sr concentrations (A) and 90Sr/Cref (B) to discharges rate. (1), (2), and (3) for each panel indicate the period used for aggregation, 1991–2000, 2001–2010, and 2011–2016, respectively. Grey dots indicate the observed values. Black dots and bars represent averages and quantiles for observed 90Sr, divided into 10 classes by the x-axis. Dashed lines express the best-fitted power-law regression lines for each period.
