Figure 7. Global PDR curve of model outputs using equally spaced log10 bins of primary production.

(a) Using annually averaged data; (b) using weekly averaged data. Units: primary production (mmol C m⁻³ d⁻¹); phytoplankton diversity (# species) (contributing >1% total biomass). Colour legend: Prochlorococcus (blue line), Synechococcus (green line), flagellates (yellow line) and diatoms (red line).
