Growth rate dependence of Sr incorporation during calcification of Emiliania huxleyi

Journal article

Reconstructing the dissolved carbon dioxide of surface waters from the δ13C of organic carbon relies on accurate determination of the growth rate of phytoplankton contributing to sedimentary organic matter. We demonstrate that the Sr/Ca ratio in the coccoliths of Emiliania huxleyi is correlated with the rates of both organic carbon fixation and calcification. An investigation of biomineralization models suggests that these three factors may be linked by the differential pumping rates of calci...
