Anthropogenic CO2 releases to the
atmosphere have changed the total inorganic carbon concentration of ocean by no
more than 3-4% at any location. Main differences between three approaches [Poisson and Chen, 1987; Gruber et al.,
1996; Friis, 2005] are presented that define
marine anthropogenic CO2 (CTant)
as deduced from total inorganic carbon. All definitions are based on a
back-calculation technique that was independently proposed by Brewer [1978] and
Chen and Millero [1979]. The overall importance of this presentation is in the
comparability of anthropogenic CO2 findings from described methods
with these derived from global bookkeeping approaches or full carbon model
results.
