Probability density functions of flow vertical velocities in the upper 200 m in October. The average probability density functions (PDFs) of the flow vertical velocities felt by particles while transiting in the upper 200 m of the water column are shown for each of the seven ensemble members separately in the October case with sinking speed of 30 m d^–1 for a) AT357 and b) GC600. Positive values indicate downward vertical velocities (and vice versa). DOI: https://doi.org/10.1525/elementa.292.f9
