Contour maps of photosynthetic rates (Panel A, in mg C m<sup>–3</sup> h<sup>–1</sup>), concentrations of Chl <i>a</i> (Panel B, in mg m<sup>–3</sup>) and assimilation numbers (Panel C, in mg C mg<sup>–1</sup> Chl <i>a</i> h<sup>–1</sup>), dissolved inorganic nitrogen (DIN, Panel D, in μM), silicate (SiO<sub>3</sub>-Si, Panel E, in μM), and phosphate (PO<sub>4</sub>-P, Panel F, in μM).
