摘要
海洋是地球表面上碳的重要贮存库,是全球碳循环系统的一个重要子系统,国际上研究海气间CO2交换调控机制的工作长期以来倍受关注。文章简要阐述海气CO2通量研究概况和对海水溶解无机碳δ13CDIC指标的地球化学特征的分析基础上,综述海气CO2通量的溶解无机碳稳定同位素示踪研究进展,并对该方法存在问题和研究发展趋势作了分析与展望。
The isotopic composition of dissolved inorganic carbon （DIC） in marine and estuarine environments has been studied in some detail because of its role in determining the isotopic composition of inorganic/organic matter and its applications to the study of various natural processes. The δ^13CDIC values in sea waters is controlled by the sources and sinks of carbon and results from isotope fractionation both between solid, dissolved and gaseous phases. In this paper, based on the analysis of the stable isotopes geochemical characteristics of dissolved inorganic carbon, we intended to review and synthesize the recent advances in Air-sea Fluxes of Carbon Dioxide traced by stable carbon isotopes.
