An analysis of the carbon balance of the Arctic Basin from 1997 to 2006
This study used several model-based tools to analyse the dynamics of the Arctic Basin between 1997 and 2006 as a linked system of land-ocean-atmosphere C exchange. The analysis estimates that terrestrial areas of the Arctic Basin lost 62.9 Tg C yr[superscript -1] and that the Arctic Ocean gained 94....

description | This study used several model-based tools to analyse the dynamics of the Arctic Basin between 1997 and 2006 as a linked system of land-ocean-atmosphere C exchange. The analysis estimates that terrestrial areas of the Arctic Basin lost 62.9 Tg C yr[superscript -1] and that the Arctic Ocean gained 94.1 Tg C yr[superscript -1]. Arctic lands and oceans were a net CO[subscript 2] sink of 108.9 Tg C yr[superscript -1], which is within the range of uncertainty in estimates from atmospheric inversions. Although both lands and oceans of the Arctic were estimated to be CO[subscript 2] sinks, the land sink diminished in strength because of increased fire disturbance compared to previous decades, while the ocean sink increased in strength because of increased biological pump activity associated with reduced sea ice cover. Terrestrial areas of the Arctic were a net source of 41.5 Tg CH[subscript 4] yr[superscript -1] that increased by 0.6 Tg CH[subscript 4] yr[superscript -1] during the decade of analysis, a magnitude that is comparable with an atmospheric inversion of CH[subscript 4]. Because the radiative forcing of the estimated CH[subscript 4] emissions is much greater than the CO[subscript 2] sink, the analysis suggests that the Arctic Basin is a substantial net source of green house gas forcing to the climate system. |
