A WOCE Expedition in the Far South Indian Ocean

这是印度洋南部深水和底水形成的合作研究，是世界海洋环流实验（WOCE）印度洋考察（IOE）的一部分。来自6个机构的6个pi将完成WOCE水文测量计划线S-4的最后一段，沿着南纬60度从东经20度到东经120度。该程序旨在检测克尔格伦高原的细微差异，这是海底水域的重要水文边界。除了水文测量外，该部分还将包括标准示踪剂测量，以及cfc、氦、氚和碳-14，所有这些都符合WOCE标准。除了纬向线外，还将对东经54度和东经96度的陆架进行两次考察，以考察南极坡锋及其相关的西向洋流。在一年的时间里，我们还将在几个地点部署消耗性的水流系泊装置，以测量克尔格伦高原斜坡和侧翼的水流。

9528545 Swift This is a collaborative study of deep and bottom water formation in the southern sector of the Indian Ocean, as part of the World Ocean Circulation Experiment (WOCE) Indian Ocean Expedition (IOE). Six PIs from six institutions will complete the final segment of the WOCE Hydrographic Program Line, S-4, along 60 degrees South from about 20 degrees East to about 120 degrees East. The program is designed to detect subtle differences across the Kerguelen Plateau, an important hydrographic boundary for bottom waters. In addition to hydrography, the section will include standard tracer measurements, as well as CFCs, Helium, Tritium, and Carbon-14, all to WOCE standards. In addition to the zonal line, two excursions to the shelf at about 54 degrees East and 96 degrees East will be made to investigate the Antarctic Slope Front and its associated westward current. Expendable current moorings will also be deployed at several locations to measure, for one year, the current along the slope and on the flanks of the Kerguelen Plateau.
