Covering Ocean Acidification: Chemistry and Considerations

Jun 24, 2008 Less carbonate makes it more difficult for corals, mollusks, echinoderms, calcareous algae and other shelled organisms to form calcium carbonate (CaCO 3), their major mineral building block.Also, when carbonate concentrations fall too low, already formed CaCO 3 starts to dissolve. So, marine organisms have a harder time making new shells and maintaining the ones they’ve already got.
