"Trend contributions: This table shows the estimated contributions to the natural air-sea CO2 flux trends, F’, as in Equation 2 [10-2 mol m-2 yr-2], averaged over the Southern Ocean (<35S). Positive fluxes are to the atmosphere. Sigma is the sum of all seven terms, and F’_mod is the modeled trend in F." ---------------------------------------------------------------------------------------- Range 1958-2004 1958-2004 1958-1978 1958-1978 1979-2004 1979-2004 Quantity Trend Congruent Trend Congruent Trend Congruent ----------------------------------------------------------------------------------------- dF/dWS* WS’ 0.09 0.09 0.01 0.01 0.12 0.12 dF/dIce * Ice’ 0 0 0 0 0 0 dF/dp * p’ 0.05 0.04 0.03 0 0.02 0.04 dF/dDIC * DIC’ 0.81 0.49 -1.11 0.01 2.03 0.75 dF/dAlk * Alk’ -0.72 -0.30 0.52 0 -1.57 -0.43 dF/dT * T’ 0.11 -0.02 0.38 0 -0.48 -0.18 dF/dS * S’ 0.06 0.03 -0.01 0 0.10 0.03 ----------------------------------------------------------------------------------------- Sigma 0.40 0.33 -0.18 0.02 0.22 0.33 F’_mod 0.54+/-0.09 0.44+/-0.04 -0.14+/-0.30 0.03+/-0.01 0.35+/-0.02 0.48+/-0.08 -----------------------------------------------------------------------------------------
