SAVE: Radiocarbon

1980年至1985年期间，国家科学基金会资助了两项测量大西洋瞬时示踪剂的运动(TTO/NAS和TTO/赤道)。一个完整的海洋盆地模拟数据库将包括一项南大西洋研究，以：1.确定二氧化碳输送及其对世界气候的影响；2.该地区主要洋流的约束模型；3.确认温跃层中新碳的添加速度增加了5倍。这项研究的八个组成部分(SAVE)将由来自LDGO、普林斯顿、华盛顿大学、WHOI和SIO的研究人员进行。这些科学家在赤道和北大西洋成功地完成了以前的研究，这为他们奠定了良好的记录。他们将提供物理和化学专业知识，这些专业知识将被用于合作努力，以实现地球化学研究的目标。这一部分的目的是利用放射性碳(C-14)追踪南大西洋的水团运动。LDGO将收集约1,000个示踪样本，并在迈阿密大学的Ostlund博士和Tap博士的指导下进行分析；哥伦比亚大学的Broecker博士将对数据进行解读。这两位主要研究人员都通过世界各地的C-14研究发展了对水运动的宝贵理解，并完全有资格在SAVE项目中执行这项任务。

Two campaigns to measure transient tracers in the Atlantic Ocean (TTO/NAS and TTO/Equatorial) were funded by NSF during the period from 1980 to 1985. A complete data base for modelling this ocean basin would include a South Atlantic Study to: 1.Determine CO2 transports and their influence on world climate, 2.Constrain models of major ocean currents in this area, and 3.Confirm an observed 5-fold increase in the addition rate of new carbon to the thermocline. Eight components of such a study (SAVE) will be performed by investigators from LDGO, Princeton, University of Washington, WHOI, and SIO. The track record of these scientists is well established by successful completion of previous studies in the Equatorial and North Atlantic. They will provide physical and chemical expertise which will be directed toward a cooperative effort to reach the goals of the geochemical study. This component is aimed at tracing water mass movement in the South Atlantic using radiocarbon (C-14). About 1000 tracer samples will be collected by LDGO and analyzed under the direction of Drs. Ostlund and Tap at the University of Miami; Dr. Broecker at Columbia University will interpret the data. Both principle investigators have developed a valuable understanding of water movement through C-14 studies around the world and are well qualified to perform this task in the SAVE project.
