Annual mean uptake of air-sea CO2 fluxes as calculated from OPA/PISCES 1990-1999 (Lenton et al., 2006<ref name="Lenton et al, 2006">Lenton, A., Metzl, N., Aumont, O., Lo Monaco, C. and Rodgers, K. 2006.

(2009<ref name="Takahashi et al, 2009">Takahashi, T., Sutherland, S.C., Wanninkhof, R., Sweeney, C., Feely, R.A., Chipman, D.W., Hales, B., Friederich, G., Chavez, F., Sabine, C., Watson, W., Bakker, D.C.E., Schuster, U., Metzl, N., Yoshikawa-Inoue, H., Masao Ishii, M., Midorikawa, T., Nojiri, Y., Kortzinger, A., Steinhoff, T., Hoppema, M., Olafsson, J., Thorarinn, S.., Arnarson, T.S., Tilbrook, B., Johannessen, T., Olsen, A., Bellerby, R., Wong, C.S., Delille, B., Bates, N.R. and De Baar, H.J.W. 2009.

The sub-Antarctic region (40-50&deg;S) represents a strong sink (blue colors), whereas south of 50&deg;S, large regions act as a CO2 source for the atmosphere (red).
