Table 3.

Input parameters and outputs from equation (4.4) for each station, as well as estimates of regenerated phosphate calculated from (AOU/150)/[PO₄³⁻] [101,102]. % [NO₃⁻]_nitn was calculated only where the difference between _CDW and was statistically significant (p < 0.05, two-sample t-tests). NS denotes differences not statistically significant. Uncertainties represent standard errors.
