The internal consistency of the North Sea carbonate system
In 2002 (February) and 2005 (August), the full suite of carbonate system parameters (total alkalinity (A T ), dissolved inorganic carbon (DIC), pH, and partial pressure of CO 2 (pCO 2 ) were measured on two re-occupations of the entire North Sea basin, with three parameters (A T , DIC, pCO 2 ) measu...
