The dissolution of carbon dioxide in sea water makes it more acidic.
a decrease in a very important form of inorganic carbon: the carbonate ion (CO32-).
Numerous marine organisms such as corals, mollusks, crustaceans and sea urchins rely on carbonate ions to form their calcareous shells or skeletons in a process known as calcification.
The concentration of carbonate ions in the ocean largely determines whether there is dissolution or precipitation of aragonite and calcite, the two natural polymorphs of calcium carbonate (CaCO3), secreted in the form of shells or skeletons by these organisms.
Today, surface waters are supersaturated with respect to aragonite and calcite, meaning that carbonate ions are abundant.
This super saturation is essential, not only for calcifying organisms to produce their skeletons or shells, but also to keep these structures intact. Existing shells and skeletons might dissolve if pH reaches lower values, and the oceans turn corrosive for these organisms.
