Abstract

Abstract

Relying on the Sharing Marine Research Plan in northeast part of the South China Sea supported by National Research Foundation in the spring of 2013,we measured pCO₂ and corresponding parameters in surface water and air by underway measurement. Combined with the corresponding hydrological and biochemical data,we discussed the distribution and variation of pCO₂. The results indicated that,effected by Pearl River diluted water and coastal upwelling and biological activity,offshore shelf areas presented an obvious sink of atmospheric CO₂,while in Luzon Strait and northwest part of Luzon areas,effected by high temperatures and the intrusion of Kuroshio Current and Luzon upwelling,showed a strong source. In general,the northeast part of the South China Sea in spring add about 4.25°10⁴ tons of carbon to atmosphere.
