Fig.4a-d Logarithmic concentration distribution of all three studied aggregate size classes
with settling velocities 30 (dashed line), SO (solid line) and 80 m day-i (dotted line) in a diffusion advection simulation for the hydrodynamic regime 1 with ulOO = 0.1 ms- i (a) and hydrodynamic regime 2 with ulOO = 0.5 ms- i (b). Fraction of the initially added total mass
(sum of all three size classes, ca. 150 g) of each aggregate size class for the hydrodynamic
regime 1 with ulOO = 0.1 ms- i (e) and regime 2 with u lOO = 0.5 ms- i (d).
