Environmental controls on the Emiliania huxleyi calcite mass
Although ocean acidification is expected to impact (bio) calcification by decreasing the seawater carbonate ion concentration, [CO 3 2− ], there is evidence of nonuniform response of marine calcifying plankton to low seawater [CO 3 2− ]. This raises questions about the role of environmental factors...
