Preserved particulate organic carbon is likely derived from the subsurface sulfidic photic zone of the Proterozoic Ocean: evidence from a modern, oxygen-deficient lake
Ashley B. Cohen, Lisa N. Christensen, Felix Weber…·Gordon T. Taylor
The paper links carbon isotope patterns in modern oxygen-deficient lake sediments to specific carbon fixation pathways and microbial communities, suggesting similar processes may explain Proterozoic ocean carbon signatures.
