9818947FiringIn this project PIs will analyze data from Acoustic Doppler Current Profilers (ADCP) used during the Indian Ocean Survey carried out as part of the World Ocean Circulation Experiment (WOCE). Shipboard ADCPs provided high resolution sections of velocity in the upper 300 meters along the survey lines. Lowered ADCPs (LADCP) provided full depth profiles at every hydrographic station along the tracks. The central objective is to describe the ocean current field in the Indian Ocean, with emphasis on the deep lowered ADCP data set. The study will also include use of other parameters measured such as temperature, salinity, chemical tracers, float and drifter tracks, satellite altimetric sea level measurements, etc. Observed currents will be compared with numerical general circulation model output to evaluate the models' ability to mimic the phenomena and dynamics of the ocean.

在这个项目中，pi将分析作为世界海洋环流实验（WOCE）一部分的印度洋调查中使用的声学多普勒电流廓线仪（ADCP）的数据。船上adcp提供了沿测量线上方300米的高分辨率速度剖面。降低的adcp （LADCP）提供了沿线每个水文测量站的全深度剖面。中心目标是描述印度洋的洋流场，重点是深度降低的ADCP数据集。这项研究还将包括使用其他测量参数，如温度、盐度、化学示踪剂、漂浮物和漂浮物轨迹、卫星测高海平面等。观测到的洋流将与数值一般环流模式输出进行比较，以评估模式模拟海洋现象和动力学的能力。
