Coral reef calcifiers buffer their response to ocean acidification using both bicarbonate and carbonate
Central to evaluating the effects of ocean acidification (OA) on coral reefs is understanding how calcification is affected by the dissolution of CO 2 in sea water, which causes declines in carbonate ion concentration [CO 3 2− ] and increases in bicarbonate ion concentration [HCO 3 − ]. To address t...

Central to evaluating the effects of ocean acidification (OA) on coral reefs is understanding how calcification is affected by the dissolution of CO 2 in sea water, which causes declines in carbonate ion concentration [CO 3 2− ] and increases in bicarbonate ion concentration [HCO 3 − ]. To address this topic, we manipulated [CO 3 2− ] and [HCO 3 − ] to test the effects on calcification of the coral Porites rus and the alga Hydrolithon onkodes , measured from the start to the end of a 15-day incubation, as well as in the day and night.
