South Atlantic Ventilation Experiment: Cross-Antarctic Circumpolar Current Ventilation

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。这部分的目的是将热通量和氟利昂梯度在南极绕极流中相互关联。这种估算经向热输运的方法是新的，如果成功，将大大提高我们测量和解释洋流界面热通量的能力。

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 correlatinag heat flux and freon gradients across the Antarctic Circumpolar Current. This approach at estimating meridional heat transport is new and if successful would significantly increase our ability to measure and explain heat fluxes across ocean current interfaces.
