Oceanic Carbon Cycle Model Analysis of a New Global Data Set of Oceanic Carbon Including Extensive 13C Data and Supporting Measurements

摘要 作为美国联合全球海洋通量研究（U.S. Joint Global Ocean Flux Study，U.S.JGOFS）综合与模拟项目的一部分，该研究团队将收集全球海水中溶解无机碳的分布和两种碳稳定同位素（13 C/12 C）的比值数据，以构建海洋碳循环和二氧化碳海-气交换的几个模型。 这些数据将来自斯克里普斯二氧化碳研究小组收集的20年数据集，以及其他含有二氧化碳成分的主要海洋计划，特别是美国JGOFS和WOCE（世界海洋环流实验）。 这些研究将有助于估计海洋吸收大气中人为二氧化碳的能力。 预计它们将提高我们目前预测下世纪全球二氧化碳趋势的能力。

ABSTRACT As part of the Synthesis and Modeling Project of the U.S. Joint Global Ocean Flux Study (U.S.JGOFS), this research team will compile data on the global distribution in seawater of dissolved inorganic carbon and the ratio of two carbon stable isotopes (13C/12C) to construct several models of oceanic carbon cycling and sea-air exchange of carbon dioxide. The data will be drawn from the 20-year dataset collected by the Scripps Carbon Dioxide Research Group and from other major ocean programs with a carbon dioxide component, especially U.S.JGOFS and WOCE (World Ocean Circulation Experiment). Such studies will allow estimates to be made of the oceanic capacity to take up anthropogenic carbon dioxide from the atmosphere. They are expected to improve our current ability to project global carbon dioxide trends into the next century.
