Short summary

This work examines the effect of salinity changes on the biogeochemistry of the coccolithophores with a palaeoproxy perspective. Although substantial changes in growth rate are observed between cells grown under various salinities, these physiological changes have no significant impact on the oxygen isotope composition of their biominerals. Thus, established coccolith δ¹⁸O / temperature calibrations are not complicated by salinity. By contrast, it does influence coccolith δ¹³C values.
