Seawater carbonate chemistry and coccolithophores and diatoms resilient to oceanalkalinity enhancement

Here, we investigatethe impacts of moderate (~700 μmol/kg) and high (~2700 μmol/kg) limestone-inspired alkalinity additionson two biogeochemically and ecologically important phytoplankton functional group representatives: Emilianiahuxleyi (calcium carbonate producer) and Chaetoceros sp. (silica producer). The growth rate and elemental ratiosof both taxa were estimated.
