WOCE Hydrographic Program Line S4 in the Indian Ocean Sector of the Southern Ocean

9415965诺林这是一项关于印度洋南部深水和底层水形成的合作研究，是世界海洋环流实验（WOCE）印度洋考察（IOE）的一部分。 来自六个机构的六名项目研究员将完成世界海洋观测实验室水文计划线的最后一段，S-4，沿沿着南纬60度，从东经20度到东经120度。 该方案旨在探测凯尔盖朗高原的细微差异，凯尔盖朗高原是底层沃茨的重要水文边界。 除了水文地理学之外，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，还将在东经50度和东经96度左右对大陆架进行两次考察，以调查南极斜坡锋及其相关的向西向海流。 还将在几个地点部署消耗性海流系泊装置，以测量沿着斜坡和凯尔盖朗高原侧翼的海流，为期一年。 在这一部分中，PI将提供整体的科学领导，目前的组成部分与俄勒冈州州立大学直接合作。

9415965NowlinThis 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 50 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. In this component, the PIs will provide the overall scientific leadership, and the current component in direct collaboration with Oregon State University.
