Figure 4. Concentrations of organic and inorganic elements in suspended and sinking particles and their contribution to the total measured elements.
Bar plots display the summed biogeochemical concentrations (in µg L-1) (A), and their relative contributions (in %) (B) of the measured organic (TEP-C, POC, PON) and inorganic (PIC, bSi and lSi) components of suspended (left) and sinking particles (right) at five depth layers (50–65, 95, 300–350 and 500 m). Biogenic and lithogenic silica were converted to mass units using a molar mass of 61 g mol-1. Here we display POC (grey) as total POC minus TEP-C. The compositional plots display background concentrations and reflect the measured particle composition.
