Figure 3: Sampling data used to calibrate PLSR models for the Reservoir Turnover Deployment ( n = 69 for total and soluble Fe, 71 for total Mn, and 70 for soluble Mn) and the Oxygen On Deployment ( n = 93 for all variables). Outliers (determined by the Monte Carlo predictive error distribution) are not included. Note that the y-axes vary among panels.
