The internal consistency of the North Sea carbonate system
International audience In 2002 (February) and 2005 (August) the full suite of carbonate system parameters (Total Alkalinity (AT), Dissolved Inorganic Carbon (DIC), pH, and partial pressure of CO2 (pCO2) were measured on two re-occupations of the entire North Sea basin, with three parameters (AT, DIC...
