Abstract
Calcium carbonate in ocean sediments is dominantly produced by shell-and skeleton-building organisms in both shallow marine and open-ocean environments. The carbonate oozes that accumulate on the sea floor serve as a major reservoir of calcium and carbon dioxide on the Earth’s surface. Their spatial and temporal accumulation patterns in the marine sediment record are a primary source of information about the carbonate chemistry and circulation of past oceans, as well as of the global geochemical cycle of CO2.
