filename: 2008gb003349_ts01.txt created: October 14, 2008 by NG last change: none Description: Auxiliary Table 1 of Gruber et al., 2008. Caption: Inverse estimates of the air-sea fluxes of natural, anthropogenic, and river derived CO2 for the 23 regions resolved by the ocean inversion (see Figure 1 in main text). Also listed is the sum of the three components, i.e., the contemporary CO2 flux, in comparison with the estimates based on the pCO2 climatology of Takahashi et al. (2008). Positive fluxes indicate outgassing.

(2003).} (b) Weighted mean fluxes estimated by the inversion. For details and estimates of the 10 individual models, see Mikaloff-Fletcher et al. (2006) (anthropogenic CO2 fluxes) and Mikaloff-Fletcher et al. (2007) (natual CO2 fluxes). (c) The riverine carbon outgassing was estimated on the basis of the spatial distribution of the input of organic and inorganic carbon into the ocean by rivers. See Jacobson et al. (2007) for details. (d) Flux estimates based on the pCO2 climatology of Takahashi et al. (2008). References: Jacobson, A. R., S. E. Mikaloff-Fletcher, N. Gruber, J. L. Sarmiento, and M.
