than a doubling, an almost 150 increase, in acidity. The coccolithosphore, Emiliania Huxley and the bivalve, Mytilus edulis. This is the measure of the energy of a system that allows the mineral to form or to dissolve. Retrieved from p?vref1 Reference Copied to Clipboard. The photos below show what happens to a pteropods shell when placed in sea water with pH and carbonate levels projected for the year 2100. Generally, the CCD is shallow in high latitudes where downwelling conveys young, surface water with relatively low concentrations of carbon dioxide into the deep ocean, depressing the CCD. Oceanic processes AND chemistry 6, oceanic Carbon Chemistry 9, research: historical AND predictions. The crux is that the CCD is not a fixed point but is rather determined by temperature, pressure and chemical composition of the water.

Calculating saturation, calcium and Ksp are constants, saturation state becomes proportional to the availability of carbonate ions. This seawater zone is referred to as being supersaturated and is where CaCO3 can form (Corliss and Honjo, 1981). The North Atlantic Ocean results differed from global findings as dense cooling waters sank to the seafloor bringing CO2 along with it (Dickson, 2009). The importance of this distinction is that when this water hits an upwelling, those higher CO2 are brought closer to the surface. A pH scale (pH -log10H) represents the acidity of a liquid ranging from 1 to 14 with 1 being extremely acidic, 7 is neutral and 14 is extremely alkaline or aviation thesis basic. This example is part of the ocean conveyor belt. At this depth, the rate of CaCO3 supplied is equal to the rate of dissolution which means all CaCO3 has dissolved (Pinet, 2009). These chemical reactions are termed "ocean acidification" or "OA" for short.
