  Changes in Ocean Chemistry. When CO 2 is absorbed by the ocean, chemical reactions occur. In particular, carbonic acid is formed and hydrogen ions are released, and as a result the pH of the ocean surface waters decrease (making them more acidic). When hydrogen ions are released in seawater, they combine with carbonate ions to form bicarbonate.

  2 #0183;#32;In addition to the oceans role as an energy reservoir moderating Earths climate, this figure illustrates its important role as a carbon reservoir interacting with the atmosphere. Almost all of the carbon in the atmosphere, the ocean, and the sediments is in its most oxidized form as CO 2 or carbonates, HCO 3 and CO 3 2, in solution or precipitates, largely CaCO 3.

  What is Ocean Acidification?

  The Chemistry. When carbon dioxide (CO 2) is absorbed by seawater, chemical reactions occur that reduce seawater pH, carbonate ion concentration, and saturation states of biologically important calcium carbonate chemical reactions are termed quot;ocean acidificationquot; or quot;OAquot; for short. Calcium carbonate minerals are the building blocks for the skeletons and shells of many marine

  The carbonate reacts with CO 2 to form bicarbonate, which leads to a further uptake of CO 2 and a decline of the CO 3 2 concentration in the ocean. All of the CO 2 derived chemical species in the water together, carbon dioxide, carbonic acid, bicarbonate and carbonate ions, are referred to as dissolved inorganic carbon (DIC).
