Abstract
Despite the fact that coccolithophorids such as Emiliania huxleyi are suspected to play an important role in carbon-cycling, there are few data from which to deduce how these organisms may respond to CO2-induced global warming. the nitrogen and phosphorus nutrient physiology of these organisms, together with its interaction with photosynthesis, needs to be studied especially in connection with the selection for coccolith forming individuals and the quantity and quality of the CaCO3 deposited in the coccoliths. Without such data, it will not be possible to model the contributions that these microalgae may play in arresting the increase in levels of atmospheric CO2.
