The variation in the depth of the CCD largely results from the length of time since the bottom water has been exposed to the surface; this is called the "age" of the water mass. ACD lies at about 2, The carbonate compensation depth is the depth toward the bottom of the ocean where the rate of dissolving of calcium carbonate is equal to the rate of precipitation of calcium carbonate in ocean water. That is why siliceous ooze is found exclusively below this level. They might be looking for help in completing an important task. The calcite compensation depth (CCD), or the depth at which the rate of carbonate accumulation equals the rate of carbonate dissolution, has fluctuated more than 2,000 metres (about 6,600 feet) in response to changes in carbonate supply and the corrosive nature of ocean bottom waters. Skeletal remains composed of calcium carbonate (CaCO3) sinking into the deep ocean are mostly microscopic plankton. Course Hero is not sponsored or endorsed by any college or university. Melting phase relations in the eclogite-carbonate system were studied at 6 GPa and 900-1500 C. In the professional experience part, our team added some skills that are aligned with the position he is applying for. [8] Ocean acidification, which is also caused by increasing carbon dioxide concentrations in the atmosphere, will increase such dissolution and shallow the carbonate compensation depth on timescales of tens to hundreds of years. FIN. The exact value of the CCD depends on the solubility of calcium carbonate which is determined by temperature, pressure and the chemical composition of the water in particular the amount of dissolved CO2 in the water.
