Chanjman nan konsantrasyon ion carbonate nan dlo lanmè kapab afekte an eta saturation (ak kon sa disponibilite byolojik) nan plizyè kalite kabonat kalsyòm (egzanp, kalsit, aragonite, oswa segondè-mayezyen kalsit.) ref Nan anpil pati nan oseyan an, dlo lanmè a se supersaturated ak respè sa yo mineral kalsyòm mineral, sa vle di gen ase kabonat kalsyòm pou kalsifye òganis yo bati vye zo eskèlèt yo ak kokiy. Sepandan, kontinyèl asidifikasyon oseyan an ap lakòz anpil pati nan oseyan an vin insaturé ak sa yo kalite kabonat kalsyòm, enben, afekte negativman kapasite nan kèk òganis yo pwodwi epi kenbe kokiy yo.

Changes in the carbonate ion concentration in seawater can affect the saturation state (and hence biological availability) of several types of calcium carbonate (e.g., calcite, aragonite, or high-magnesian calcite.) ref In many parts of the ocean, the seawater is supersaturated with respect to these calcium carbonate minerals, meaning that there is enough calcium carbonate for calcifying organisms to build their skeletons and shells. However, continued ocean acidification is causing many parts of the ocean to become undersaturated with these types of calcium carbonate, thus adversely affecting the ability of some organisms to produce and maintain their shells.
