Agulhas Current Variability and Loss of Water into the SE Atlantic Ocean in the Retroflection Region

在这个项目中，PI将参与一项合作研究工作，研究南非周围和大西洋东南部的中深度环流。其他合作者来自Lamont-Doherty地球观测站、美国国家海洋和大气管理局大西洋海洋学和气象学实验室、德国基尔的Meerskunde研究所和南非开普敦大学。第一个目标是使用等环流RAFOS浮标来确定阿古拉斯海流靠近其反射区域时的扩散路径，并确定水体向东循环的条件。第二个目标是启动一个直接测量阿古拉斯海流在德班附近的质量运输的项目，使用速度测量（带有POGO的全球定位系统）和水文测量模型的组合。POGO是20年前使用的下投探空仪的现代版本。该项目将在第一年提供50个RAFOS浮标，第二年提供4个POGO仪器。

9617986 Rossby In this project, the PI will collaborate in a cooperative research effort to study the mid-depth circulation around South Africa and in the Southeastern Atlantic. Other collaborators are from the Lamont-Doherty Earth Observatory, NOAA Atlantic Oceanographic and Meteorology Laboratory, the Institute fur Meerskunde, in Kiel, Germany, and the University of Capetown, South Africa. The first objective is to use isopycnal RAFOS floats to determine pathways of dispersal from the Agulhas Current as it approaches the region where the current retroflects, and to determine the conditions under which waters recycle to the east. The second objective is to start a program of direct measurements of mass transport of the Agulhas Current off Durban, using a combination of velocity measurement (Global Positioning System with POGO) and hydrographic casts. POGO is a modern version of the dropsonde, used some two decades ago. This project will provide 50 RAFOS floats in the first year, and 4 POGO instruments in the second year.
