I am a palaeoceanographer and I am interested in the changes of planktonic foraminifera shell weights. I have identified a relationship between ocean density and their shell weight, which may be for depth regulating purposes. This mechanism however is directly relevant to the carbon cycle. Through my research in Oxford, I am trying to assess the extent to which this process affects pelagic calcification and eventually the atmospheric CO2 concentrations and our climate.
