Fig. 5: Results for the oxic and anoxic environmental models introducing upwelling processes.

a Represents an anoxic + upwelling scenario illustrating an upwelling margin under a low-oxygen atmosphere. b Represents an oxic + upwelling scenario characterized by an upwelling margin within a well-oxygenated atmosphere. In (a) and (b), the left map displays the distribution of primary productivity (PP) and the anoxic fraction across the basin, the centre map shows the TOCS based on the interplay between PP and redox conditions and the plot on the right shows the correlation between TOCmc and TOCS values. TOCS simulated TOC, TOCmc measured and corrected TOC. Sections are from this study (bold) and the literature.

The coloured circles overlaying this map correspond to the average TOCmc values from Member IV organic-rich samples, as compiled in Supplementary Fig. S5.
