传统船舶调查获取海洋水体温盐资料的方法在水平方向上分辨率较低,而用反射地震探测海洋水体特性的方法——地震海洋学,能有效提高海水温盐资料在水平方向上的分辨率。概述了近5年来地震海洋学的发展过程,重点介绍了地震海洋学方法在海洋锋面观测、水团边界划分、海洋内波分析、中尺度涡旋等方面的研究成果,以及AVO、全波形反演等反射地震处理方法在海洋水体特性研究中的应用。比较了地震海洋学方法与声层析技术、高频声技术等声学方法应用于海洋水体特性研究的异同。并展望了下一步研究工作的重点:①有关地震反射剖面的各种参数与海洋水体温盐结构物理模型的联系及其定量分析;②以研究海洋水体特性为目标的地震反射剖面的处理方法;③海洋地震调查历史数据的应用。
The traditional method of ship survey to obtain temperature and salinity data of ocean water has a low resolution in the horizontal direction. However, the method of seismic exploration of marine water features - seismic oceanography can effectively improve the resolution of seawater temperature and salinity data in the horizontal direction . The development of seismic oceanography in recent five years is summarized. The research results of seismic oceanographic methods in ocean front observation, water mass boundary division, ocean internal wave analysis, mesoscale vortex and so on are summarized, as well as AVO, Application of Equivalent Method of Reflective Seismic Treatment in the Research of Ocean Water Body. The similarities and differences between oceanographic methods and acoustic tomography, high-frequency acoustic techniques and other acoustic methods applied to the study of marine water characteristics are compared. The key points of the next research work are as follows: (1) the connection and quantitative analysis of various parameters of seismic reflection profile with the physical model of ocean-salt temperature and salinity structure; (2) the treatment method of seismic reflection profile with the aim of studying the characteristics of marine water body; ③ oceanographic survey historical data applications.
