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.

提出了一项现场实验，该实验将提供从厄加勒斯逆反射区域到南大西洋副热带环流的盐、热量和质量传输的多年时间序列。 该计划将部署带有或不带有压力传感器和近海底海流计的倒置回声测深仪。现场数据将得到卫星数据（海表温度和高度测量）的补充。 历史数据也将纳入数据分析中。 该计划的成功主要基于新技术 GEM-ETTA，用于分析 IES（倒置回声测深仪）和 PIES（压力和倒置回声测深仪）数据。 对现场数据的分析结合对历史数据的重新分析将提供这些流域间通量在年际尺度上的第一个长期时间序列。
