sets of sensitivity runs for three N concentrations spanning three orde rs of
magnitude (0.0003, 0.003 and 0.030 moles/rn '). For each run , the Si concentration is varied (0.001, 0.003, 0.008 moles/rn '), produ cing a range of
Si : N ratios from 0.033 to 26.67. All nine runs are shown in Figure 8.16. The
first set of runs (Graphs 1 through 3 in Figure 8.16), with 0.001 moles/rn ' of
Si, shows the ratio of diatoms to dinoflagellates as being below 1. With
