The degradation of organic m atter at the seawater-sediment interface plays an important role in the pattern of calcium carbonate preservation in the deep sea. A model developed to quantify this effect shows that the amount of calcium carbonate dissolved by metabolic CO2 at the sediment-water interface is dependent upon the rain ratio of organic carbon and calcium carbonate, and the rates of organic matter degradation and calcite dissolution....
