Collaborative Research: Acoustic Doppler Current Profiling on the U.S. WOCE Hydrographic Program Expedition to the Indian Ocean

9413172在这个项目中，作为印度洋考察的一部分，PI将直接测量六个WOCE水文计划(WHP)区段的海洋速度结构，并开始数据处理和初步科学分析。将在WOCE断面I2(北纬10°)、I7S(东经54°)、I5W/I4(南纬25°和南纬30°)、I7N(阿拉伯海)、I8N/I5E(东经80°和南纬30°)、北纬(95°E)和I8S/I9S(澳大利亚东南部子午线断面)进行测量。船用声学多普勒海流剖面仪(ADCP)将用于所有区段，在这些区段的选定部分使用独立的ADCP随CTD(电导率/温度/(电导率/温度/深度)单元)降低的速度结构的全深度剖面。除了确定当前结构的各个方面外，这些数据还将为反向模型提供额外的约束。

9413172 Firing In this project, PIs will directly measure ocean velocity structure along six WOCE Hydrographic Program (WHP) sections as part of the Indian Ocean Expedition (IOE), and begin data processing and initial scientific analyses. Measurements will be made on sections designated as WOCE sections I2 (10degN), I7S (54degE), I5W/I4 (25degS and 30degS), I7N (Arabian Sea), I8N/I5E (80degE and 30degS), I9N (95degE), and I8S/I9S (meridional sections SE of Australia). A shipboard Acoustic Doppler Current Profiler (ADCP) will be used on all sections, with full depth profiles of velocity structure made at selected portions of these sections using a self- contained ADCP lowered with the CTD (Conductivity/Temperature/ (Conductivity/Temperature/Depth)Depth) unit. In addition to determining various aspects of the current structure, the data will provide an additional constraint for inverse models.
