Abstract:
Coccolithophores, a diverse group of phytoplankton, make important contributions to pelagic calcite production and export, yet the comparative biogeochemical role of species other than the ubiquitous Emiliania huxleyi is poorly understood. Here we examined the relative importance of E. huxleyi and two Coccolithus species (Coccolithus pelagicus and Coccolithus braarudii), in terms of daily calcite production, by culturing E. huxleyi and Coccolithus in parallel, and comparing growth rates and biometrically determined cellular carbon calcite quotas. Biometric measurements of Coccolithus species, and E. huxleyi cell diameters, were performed using polarised light microscopy. Scanning electron microscopy was used for all other biometric measurements of E. huxleyi.
