Figure 14 (a). The effect of the biological model on the surface pCO2. The model pCO2 curves were generated using the "standard" model (dark line), a "bloom" model (lower stippled line), and a "dead" model (upper stippled line). See text for explanation. (b) Air-sea carbon fluxes from the model runs in Figure 14 (a). Solid line is the "standard" model; lower stippled line in the "bloom" model; upper stippled line is the "dead" model.
