Abstract:

In the present work the CO 2 differences between P CO 2 in the surface water and p CO 2 in the atmosphere were determined on the route frome Qindao to Antarctica during Eighth Chinese Antarctic Research Expedition in 1991 . The result of survey indicate: the sea area in north of 7°N , between the equator and 2°S, between 10°S and 43°S, in south of 58° S, serves as a sink for atmospheric CO 2 ,the mean CO 2 fluxes from atmosphere into sea water was about 6.1mg/(m 2·h); the sea area between 7°N and the equator, between 2°S and 10°S, between 43°S and 58°S acts as CO 2 sources, the mean CO 2 fluxes from sea water into atmosphere was about 4.0mg/(m 2·h).
