The above method has been applied to TTDs inferred from measurements of transient tracers in the subpolar North Atlantic Ocean.

Average vertical variation of ΔDIC in 1993 for (a) Irminger Sea, (b) Iceland Basin, (c) Newfoundland Basin, (d) west European Basin, calculated from CFC12 data and TTDs with Δ = 0 (dashed) or Δ = Γ (solid).



Comparison of ΔDIC around 50N 20W from Δ = Γ (solid) and Δ = 0 (dashed) calculations with previous estimates (horizontal lines).



Average vertical variation of increase in ΔDIC between 1980 and 1999 for (a) Irminger Sea, (b) Iceland Basin, (c) Newfoundland Basin, (d) west European Basin, calculated from CFC12 data and TTDs with Δ = 0 (dashed) or Δ = Γ (solid).
