Species-specific calcite production reveals Coccolithus pelagicus as the key calcifier in the Arctic Ocean
Through the production and export of their calcite coccoliths, coccolithophores form a key component of the global carbon cycle. Despite this key role, very little is known about the biogeochemical role of different coccolithophore species in terms of calcite production, and how these species will r...

Through the production and export of their calcite coccoliths, coccolithophores form a key component of the global carbon cycle.
