摘要
在1985年～1997年之间'陆架边沿海海洋通量研究'和'中美海气联合调查'(TOGA)海洋观测调查项目中,利用库仑仪系统和高精度测量海水二氧化碳分压气相色谱系统测量了表层和深层海水总溶解二氧化碳(TCO2)、海水和大气CO2分压(PCO2)样品,测量精度为±1umol/kg和±1utam.根据表层和深层CO2数据,讨论了影响CO2变化的主要因素,通过研究计算获得了CO2和温度(T)、盐度(S)、总碱度(ALK)相关回归方程.CO2分布变化与流、水团、黑潮变化密切相关.本文根据在中国东海四个航次测量的海水和大气的PCO2,描述了调查海域CO2的源与汇以及通量的分布.
The total dissolved carbon dioxide (TCO ) in surface and deep water, the partial pressure in air (PCO ) and in surface water (PCO ) were measured with the coulometer and gas chromatography systems with precision of ±1umol/kg and ±1utam, respectively during“JGOFS”and “TOGA”.based on CO data in surface and deep water measured, the main influence factors on CO in sea water were discussed. The correlation and regression equation between CO and Temperature (T), salinity (S), total alkali (TALK) and PH were given. The distribution and variation of CO may be related to the current, water mass and Kuroshio. In this paper, on the basis of the data of PCO (a) and PCO (w) were measured during the four crusis In the East China Sea,we describe the distribution And variation of CO the sources and sinks and flux of CO .
