Figure 18. Comparison of organic matter C/N ratios and TOC concentrations of sediments from Hole 1083A. The correspondence between increases in both parameters indicates that preservation of marine organic matter during early diagenesis is important to enhancing the organic carbon richness of sediments near the Walvis Ridge.
