Figure 3. Molar ratios of ballast minerals and TEP to POC in
suspended and sinking particles versus depth.
Scatter plots display the depth profile of molar PIC:POC ratios (A),
molar bSi:POC ratios (B), molar lSi:POC ratios (C) and molar TEP-C:POC
ratios (D) calculated for suspended (white triangles) and sinking (black
circles) particles. Dash and continuous line are smoothing spline used
to enhance trends visualization and thus do not have statistical
significance. Outliers of suspended molar bSi-POC ratio (0.35, 500 m)
and sinking PIC-to-POC ratios (12.4, 350 m) have been removed to better
display depth trends, which are not affected by their exclusion.
