Seawater carbonate chemistry and physiological data for coccolithophores under OAE treatment

Here we examined the growth, calcification response, and morphology of these two key "endmember" species of coccolithophore (Gephyrocapsa huxleyi and Coccolithus braarudii) to ocean alkalinity enhancement using in vitro laboratory culture experiments. We also compared how the addition of the monovalent cation Na+ and divalent cation Ca2+ to raise total alkalinity affected growth and calcification responses.
