Hydrographic and Velocity Fields in the Southwestern South Atlantic--A Winter from FS Polarstern

在这个项目中，PI将利用德国研究船FS Polarstein上的可用时间来研究大西洋东南部的冬季对流和输送，重点是福克兰洋流、巴西洋流的向极延伸和反气旋返回，以及1992年冬季南极绕极洋流的两个主要锋面。将进行电导率、温度与深度(CTD)、氧气和营养物质的测量。还将部署8个水面漂移器，以获得绝对拉格朗日海流数据，以便与水文测量进行比较。

In this project, the PI will exploit available ship time on the German research vessel, FS POLARSTERN, to study wintertime convection and transport in the southeastern Atlantic Ocean, with focus on the Falkland Current, the poleward extension and anticyclonic return of the Brazil current, and two major fronts of the Antarctic Circumpolar Current during the Austral winter of 1992. Conductivity, Temperature vs Depth (CTD), oxygen, and nutrient measurements will be made. Eight surface drifters will also be deployed to obtain absolute Lagrangian current data for comparison with the hydrographic measurements.
