Figure 2. Time-averaged concentrations of biogeochemical
components in suspended and sinking particles and the partition of
sinking particles to total.
Bar graphs display background suspended (left) and sinking (middle)
particles and the fractional contribution of sinking particle
concentrations to the total (in %; right) for (A) POC, (B) PIC, (C)
bSi, (D) lSi, (E) TEP concentrations. Outliers are represented as red
triangles. The values are cruise-wide averages calculated for six depth
layers (20–25, 50–65, 95, 195, 300–350 and 500 m). Error bars are the
standard deviations of the concentrations averaged within each depth
layer and thus are reflective of the dataset variability rather than the
propagated uncertainty of each datapoint. Numbers on the right of each
bar plot are representative of the total number of observations per
depth layer. Note that the differences in the number of observations
between sinking and suspended particles is reflective of loss of samples
during analysis. Note differences in scales.
