Figure 1. Relative contribution of particle abundances
per size (4 to > 32 μm) versus depth.
Bar plots display the contribution in % of suspended (A) and sinking
(B) particle concentrations in 4 size bins based on the octave scale
(4–8, 8–16, 16–32 and > 32 μm) and on the particle
equivalent spherical diameter (ESD). Concentrations are calculated as
cruise-wide averages for 6 depth layers (20–25, 50–65, 95, 195,
300–350 and 500 m). Numbers of stations per depth layer are 2, 10, 10,
2, 4 and 2, respectively for bins between 4 and 32 μm and 2, 4, 5, 2, 2
and 1 for the largest size bin (> 32 μm). Sinking particles
(> 32 μm) were at the detection limit of our method.
