摘要
The data were collected during Chinese Arctic and Antarctic Expeditions in the western Arctic Ocean and themarginal sea ice zone (MSIZ) of the Southern Ocean, respectively in the boreal summer from July to September of1999 and in the austral summer from December of 1999 to January of 2000. The concentrations of CO2 in surfacewater of the survey regions would mostly present lower than those in the atmosphere. A significant biologicaldriving force could also been observed in summer waters in both of the above oceans. Air to sea CO2 fluxes were alsocalculated to compare oceanic uptake capacity of CO2 in both oceans with the world oceans using Liss, Wanninkhof,and Jacobss methods. The averaged CO2 fluxes of air to sea in the western Arctic Ocean or in the MSIZ of theSouthern Ocean doubled that in the world oceans.
