Figure 4. Time series plots of A) Schmidt stability, B) water temperature, C) dissolved oxygen, D) predicted total Fe concentrations (lines) with observed values (dots) and 90% predictive intervals (shaded areas), and E) predicted total Mn concentrations (lines) with observed values (dots) and 90% predictive intervals (shaded areas) during the Reservoir Turnover Deployment. The dashed vertical line on 02 November 2020 represents reservoir turnover, defined by the first time point at which the temperature differential between 0.1m and 9m was less than 1 degree Celsius. Colors of lines (PLSR predictions) and dots (samples) are shown on the color scale to the right. Note that the reservoir temporarily re-stratified after 02 November 2020. Time series plots for soluble Fe and Mn are shown in Figure S16.
