【摘要】

【Abstract】The data were collected during Chinese Arctic and Antarctic Expeditions in the western Arctic Ocean and the marginal sea ice zone (MSIZ) of the Southern Ocean,respectively in the boreal summer from July to September of 1999 and in the austral summer from December of 1999 to January of 2000.The concentrations of CO2 in surface water of the survey regions would mostly present lower than those in the atmosphere.A significant biological driving force could also been observed in summer waters in both of the above oceans.Air to sea CO2 fluxes were also calculated to compare oceanic uptake capacity of CO2 in both oceans with the world oceans using Liss,Wanninkhof,and Jacobs's methods.The averaged CO2 fluxes of air to sea in the western Arctic Ocean or in the MSIZ of the Southern Ocean doubled that in the world oceans.
