The Northward Flow of Intermediate Water in the Benguela Current and Its Extension in the Eastern South Atlantic

在这个项目中，pi将研究本格拉洋流，因为它向北流过南大西洋并穿过赤道。具体目标是测量由本格拉-阿古拉斯系统带入南大西洋的中间水的流量，并追踪其向西北延伸的轨迹。RAFOS浮标的设计目的是漂浮在海洋的特定深度，并与系泊的声源进行通信，定期给出声源的位置，从而推断出该深度的声源速度。将在本格拉洋流下游的中间水域（约700米）和几个阿古拉斯漩涡中部署30个这样的漂浮物，并对其进行跟踪，以估计它们对运输的贡献。这项工作将与南非（电导率温度深度（CTD）调查）和德国科学家（18个额外的浮标和两个额外的声源）合作进行。这些观测预计将提供流场的可视化和速度统计数据，这些数据将用于开发和验证海洋温盐环流模型。

9528574 Richardson In this project, PIs will study the Benguela Current as it flows northward through the South Atlantic and across the equator. Specific objectives are to measure the flow of Intermediate Water that is carried into the South Atlantic by the Benguela-Agulhas system, and to trace its extension northwestward. RAFOS floats are designed to float at a given depth in the ocean, and to communicate with moored sound sources in a way that gives their location periodically from which velocities at that depth may be inferred. Thirty such floats will be deployed and tracked downstream of the Benguela Current at the level of the Intermediate Water (about 700 meters), and in several Agulhas eddies to estimate their contribution to the transport. The work will be carried out in collaboration with South African (Conductivity Temperature Depth (CTD) surveys) and German scientists (18 additional floats and two additional sound sources). The observations are expected to provide a visualization of the flow field and velocity statistics which will be applied to developing and validating models of the thermohaline circulation of the ocean.
