摘要:
系统总结了逆式回声测量仪（IES）的发展历史，重点介绍了其目前在世界范围内的应用情况，并阐述了CPIES（集成流速和压力传感器的IES）在我国吕宋海峡周边布放的意义及对未来应用的展望。结果表明采取不同的排列方式布放的IES阵列所获取的数据通过结合地转经验模态GEM（gravest empirical mode）以及最优插值方法能够获得观测海区的温度、盐度和流场的三维空间分布特征。基于CPIES的应用，可深入地研究多尺度的海洋动力过程，如内波、内潮和中尺度涡等，对后续大洋环流理论发展、中尺度涡产生和消亡机理、海洋中不同尺度能量串级等具有重要意义。

Abstract:
The development history of inverted echo sounder (IES) is summarized systematically, and its current application in the world is introduced. The significance of the CPIES (IES integrated with pressure and current sensors) array deployed near the Luzon Strait in China and the prospect of its future application are expounded. The results show that the data obtained from the IES arrays, combined with the gravest empirical mode (GEM) and the optimal interpolation method, can obtain the three-dimensional spatial distribution characteristics of temperature, salinity and flow filed in the observed sea area. Based on the application of CPIES, multi-scale ocean dynamic processes, such as internal waves, internal tides and mesoscale eddies, can be further studied in future. More than that, its great significant to study the development of ocean circulation theory, the generation and extinction mechanism of mesoscale eddies, and energy transform at different scales in the ocean.
Key words:inverted echo sounder (IES)oceanocean dynamicmesoscale processes
