Fig. 18.4 Fraction of area covered by E. huxleyi blooms from 1982 to 2006 in the four regions.
Weekly bloom episodes are plotted as lines as in Fig. 18.3; diamonds (◊) show integrated annual
amounts normalized by the maximum for the time series. Regression lines for the annual values are
superimposed with slopes, standard errors, correlation coefficients, and probabilities itemized in
