Figure 5. Time series plot 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 area), and E) predicted total Mn concentrations (lines) with observed values (dots) and 90% predictive intervals (shaded areas) during the Oxygen On Deployment. The dashed vertical line represents the time that the HOx was turned on. Time series plots for soluble Fe and Mn are shown in Figure S17. Note that the MUX was not collecting data from 11:00 EDT 31 May 2021 until 14:30 EDT 4 June 2021 due to technical issues. Gaps in DO and water temperature data are due to sensor malfunction and/or maintenance.
