lè CO2 lanmè a absòbe, reyaksyon chimik rive. An patikilye, asid kabonik fòme epi iyon idwojèn yo lage, e kòm rezilta pH dlo nan sifas oseyan an diminye (fè yo pi asid). Lè iyon Idwojèn yo lage nan dlo lanmè yo, yo konbine avèk iyon carbonate yo fòme bikarbonat. Pwosesis sa a diminye konsantrasyon ion carbonate. Rediksyon nan iyon kabonate ki disponib se yon pwoblèm pou kalsifikatè maren (koray, kristase, ak molki yo) ki bezwen iyon carbonate yo bati kokiy yo ak vye zo eskèlèt.

When CO2 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. This process lowers the carbonate ion concentration. The reduction of available carbonate ions is a problem for marine calcifiers (corals, crustaceans, and mollusks) who need the carbonate ions to build their shells and skeletons.
