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.

在这个项目中，南极考察船将利用德国FS POLARSTERN考察船的可用时间，研究大西洋东南部的冬季对流和运输，重点研究1992年南方冬季期间的福克兰洋流、巴西洋流向极地延伸和反气旋返回以及南极环极洋流的两个主要锋面。将进行电导率，温度与深度（CTD），氧气和营养测量。还将部署8台地面漂船，以获取绝对拉格朗日电流数据，以便与水文测量结果进行比较。
