Identify the CCD, and describe the distribution of calcareous oozes in the deep ocean. What will be an ideal response?
The calcium carbonate compensation depth (CCD) is the depth in the ocean that the
rate at which calcareous sediments are supplied to the seabed equals the rate at which
those sediments dissolve. Below this depth, the skeletons of calcium carbonate
dissolve on the seafloor, so no calcareous oozes accumulate. Calcareous sediment
dominates the deep-sea floor at depths of less than about 4,500 meters (14,800 feet),
the usual calcium carbonate compensation depth. Calcareous oozes cover about 48%
of the surface of deep-ocean basins.
