A field experiment is proposed, which will provide multi-year time series of salt, heat, and mass transports from the Agulhas retroflection region into the South Atlantic subtropical gyre. The program will deploy inverted echo sounders, both with and without pressure sensors and near-bottom current meters. The in situ data will be complemented with satellite data, both SST and altimetry. Historical data will also be included in the data analysis. The success of the program is based substantially on a new technique, GEM-ETTA, for analyzing IES (inverted echo sounder) and PIES (pressure and inverted echo sounder) data. Analysis of the field data in conjunction with reanalysis of historical data will provide the first long-term time series of these inter-basin fluxes on interannual scales.

提出了一个现场实验，该实验将提供多年的盐，热量和从阿古尔哈斯（Agulhas）翻新区域转运到南大西洋亚热带回旋的质量运输。 该程序将在有或没有压力传感器的情况下部署倒置回声声音和接近底部电流仪表。原位数据将与SST和Altimetry的卫星数据相辅相成。 历史数据也将包括在数据分析中。 该程序的成功基本上是基于一种新技术Gem-Etta，用于分析IES（倒置回声器）和派（压力和倒置回声声音）数据。 结合对历史数据的重新分析对现场数据的分析将提供这些巴蛋白间通量的第一个长期时间序列。
