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.
