Deep-Sea Oxygen Depletion and Ocean Carbon Sequestration During the Last Ice Age

Anderson, Robert F.; Sachs, Julian; Fleisher, Martin Q.; Allen, Katherine A.; Yu, Jimin; Koutavas, Athanasios; Jaccard, Samuel

Description

Enhanced ocean carbon storage during the Pleistocene ice ages lowered atmospheric CO2 concentrations by 80 to 100 ppm relative to interglacial levels. Leading hypotheses to explain this phenomenon invoke a greater efficiency of the ocean's biological pump, in which case carbon storage in the deep sea would have been accompanied by a corresponding reduction in dissolved oxygen. We exploit the sensitivity of organic matter preservation in marine sediments to bottom water oxygen concentration to...[Show more]
