Comments "In the surface ocean, for example, total dissolved inorganic carbon (i.e., TCO2) is approximately 2mM, while [CO2] is only about 10µM. This [CO2] is close to that of the atmosphere (correponding to approximately 375µmol/mol total gas) so that there is approximately a 50-fold higher concentration of dissolved inorganic carbon in the ocean than of CO2 in the atmosphere."
