Theoretical distributions (red line) of the total <i>chl a</i> and <i>Dvchl a</i> concentration (stochastic approach).

The profiles were obtained in stationary regime for different values of (case 1 of the stochastic model) as a function of depth. The results are compared with the distributions of the total chl a and Dvchl a concentration measured (green line) in site L1105. The theoretical values were obtained averaging over numerical realizations. The values of the parameters are those shown in Table 1. The noise intensities are: (a) (deterministic case), (b) , (c) , (d) , (e) and (f) . (Color online).
