CHANGES in bottom-water oxygen concentration are commonly invoked to account for past changes in sedimentary organic carbon accumulation, as organic matter is more readily preserved in anoxic conditions1–5. On the other hand, upper-water productivity has been shown to be the main controlling factor for accumulation of organic matter in modern sediments6,7. It is therefore important to understand whether productivity significantly influenced accumulation patterns in the past, for example during… CONTINUE READING
