SAVE: Radiocarbon

1980 - 1985年期间，美国国家科学基金会资助了两项大西洋瞬态示踪剂测量运动（TTO/NAS和TTO/赤道）。建立这一海洋盆地模型的完整数据库将包括一项南大西洋研究，以便：2.确定CO2运输及其对世界气候的影响；2 .限制该地区主要洋流的模式；确认已观测到的向温跃层添加新碳的速率增加了5倍。这项研究（SAVE）的八个组成部分将由来自LDGO、普林斯顿大学、华盛顿大学、WHOI和SIO的研究人员进行。这些科学家成功地完成了以前在赤道和北大西洋的研究，从而建立了良好的记录。它们将提供物理和化学专门知识，这些专门知识将用于合作努力，以实现地球化学研究的目标。这个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。在dr的指导下，LDGO将收集约1000个示踪样品进行分析。迈阿密大学的奥斯特伦德和塔普；哥伦比亚大学的布勒克博士将解读这些数据。两位主要研究人员通过在世界各地进行碳-14研究，对水的运动有了有价值的了解，他们很有资格在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.
