Collaborative Research: Aghulas-South Atlantic Thermohaline Transport Experiment (ASTTEX)

提出了一个现场实验，这将提供多年的时间序列的盐，热，和质量输送从厄古拉斯回射区到南大西洋副热带环流。 该计划将部署倒置回声测深仪，无论有没有压力传感器和近底流速计。现场数据将得到SST和测高卫星数据的补充。 历史数据也将纳入数据分析。 该计划的成功主要是基于一种新的技术，GEM-ETTA，用于分析IES（反向回声测深仪）和PIES（压力和反向回声测深仪）数据。 结合对历史数据的再分析，对实地数据的分析将提供这些跨流域通量在年际尺度上的第一个长期时间序列。

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.
