Figure 5. — Comparison of the SAM index and the climate-driven variability of CO₂ and O₂ air–sea fluxes from the GOBM mean, pCO₂ product mean and APO inversion. (a) The detrended time series of the SAM index, which has been decomposed into (b) a decadal component and (c) an interannual component, and compared with the decadal and interannual components from CO₂ (d and e, the right-hand axes are inverted) and O₂ (f and g) air–sea fluxes. Fluxes are defined as positive from the atmosphere into the ocean. (Online version in colour.)
