In order to elucidate seasonal and interannual variations of oceanic CO₂ uptake in the Greenland Sea and the Barents Sea, partial pressures of CO₂ in the surface ocean (pCO₂^sea) were measured from 1992 to 2001. The values of pCO₂^sea were lower than the partial CO₂ pressures in the atmosphere (pCO₂^air) throughout the year, and the annual net air-sea CO₂ fluxes in the Greenland Sea and the Barents Sea were evaluated to be 52 ± 31 and 46 ± 27 gC m^-2 yr^-1, respectively, yielding a total oceanic CO₂ uptake of 0.050 ± 0.030 GtC yr^-1. We also found that the annual mean CO₂ uptake was positively correlated with the North Atlantic Oscillation Index (NAOI) via wind strength, but was negatively correlated with DpCO₂ (pCO₂^air-pCO₂^sea) and the sea ice coverage. The results also indicate that the wind speed and sea ice coverage play a major role in determining the interannual variation of CO₂ uptake, with DpCO₂ playing a minor role.
