<p>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 <i>chl a</i> and <i>Dvchl a</i> 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 <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0066765#pone-0066765-t001" target="_blank">Table 1</a>. The noise intensities are: (a) (deterministic case), (b) , (c) , (d) , (e) and (f) . (Color online).</p
