0236527/ 0236654 Richardson/WoodingThis project consists of an analysis of the trajectories of RAFOS floats, deployed as part of the KAPEX experiment around the southern tip of Africa, in combination with ancillary data from surface drifters and satellite-borne altimeters. Preliminary analysis of these trajectories show that many of them were trapped in Agulhas eddies. A motivation for this work is the belief that Agulhas eddies both provide a significant conduit for flow from the Indian Ocean into the Atlantic and stir the ocean in the south-eastern Atlantic. The proposed analysis seeks to summarize the life history and statistics (including: number, size, swirl velocity, translational velocity, and the interactions of eddies with each other and with bathymetry). The investigator will compare the details of the trajectories with output from various numerical models of the region and collaborate with a German investigator in mapping the intermediate-depth velocity field in the S. Atlantic.

0236527/0236654 Richardson/ Woodingthis项目由对Rafos Floats的轨迹进行分析，该项目是非洲南部尖端的Kapex实验的一部分，结合了地表漂移器和卫星 - 型甲板的Altimeters的辅助数据。 对这些轨迹的初步分析表明，其中许多被困在Agulhas涡流中。这项工作的一个动机是，信念Agulhas eddies都为从印度洋流入大西洋的流动提供了一个重要的渠道，并在东南大西洋的海洋中搅动了海洋。 拟议的分析旨在总结生活史和统计数据（包括：数量，大小，漩涡速度，翻译速度以及互动彼此以及与测深的相互作用）。 研究人员将将轨迹的细节与该地区各种数值模型的输出进行比较，并与德国研究人员合作，以映射S. Atlantic的中间深度速度场。
