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.

在大西洋测量瞬时示踪剂的两次活动 海洋（TTO/NAS和TTO/赤道）由NSF资助， 从1980年到1985年。 用于建模的完整数据库 这一海洋盆地将包括一项南大西洋研究，以便： 1.确定CO2传输及其对世界的影响 气候， 2.在这一地区主要洋流的约束模型， 和 3.确认观察到的添加量增加5倍 新碳进入温跃层的速率。 该研究（SAVE）的八个组成部分将由 来自LDGO，普林斯顿，华盛顿大学， Whoi和SIO。 这些科学家的记录是良好的 通过成功完成以前的研究， 赤道和北大西洋。 他们将提供物理和 化学专业知识，将直接向合作 努力实现地球化学研究的目标。 这一部分的目的是跟踪水团运动， 使用放射性碳（C-14）测量南大西洋。大约1000个示踪剂 样本将由LDGO收集，并根据 在迈阿密大学的奥斯特伦德博士和塔普博士的指导下， 哥伦比亚大学的Broecker将解释这些数据。 两 主要的调查人员已经形成了一种有价值的理解 水的运动通过C-14研究在世界各地， 在SAVE项目中执行此任务的资格。
