Figure 7. Normalized fluxes (µmol g⁻¹ AFDM m⁻² hr⁻¹) of (A) Total inorganic nitrogen (TIN); (B) phosphate (PO${}_4^{3-}$); (C) silicate (Si(OH)₄); and (D) N:P flux ratios, plotted against the normalized oxygen flux.

The solid black line indicates the hypothetical regional elemental ratio as a reference, the dashed lines indicate the confidence band.
