Figure S2. Time-averaged concentration of PON in suspended and sinking particles and the partition of sinking particles to total.
Bar graphs display background suspended (left) and sinking (middle) and the fractional contribution of sinking particle concentrations to the total (in %; right) for PON 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 are representative of the total number of observations per depth layer.
