胶州湾水体中的二氧化碳体系

THE CARBON DIOXIDE SYSTEM IN JIAOZHOU BAY

采用库仑滴定法测定了胶州湾海域 4个航次的总二氧化碳 ,根据测定的总二氧化碳的数据计算了二氧化碳各分量的含量及二氧化碳分压 ,得到了胶州湾水体中二氧化碳体系的平面分布、垂直分布及周日变化规律 ,并对结果进行了初步探讨。

This paper discussed total carbon dioxide in Jiaozhou Bay on the data of four cruises from Aug.1995,Nov.1995,Feb.1996 to Aug. 1996 as determined by coulometry analysis.The spacial and vertical distribution of total carbon dioxide,their diurnal and seasonal variations were obtained .The results showed that the values of total carbon dioxide contents in seawater near the coast and estuary regions were higher than those far from them,the seasonal variation of total carbon dioxide in seawater was evident,which was higher in winter and lower in summer,vertical distribution of total carbon dioxide was remarkable,which was higher in the bottom seawater and lower in the surface seawater.The content of carbon dioxide may be controlled by hydrological,chemical and biological factors.
