地震海洋学是利用传统的低频海洋地震反射技术进行物理海洋学研究的一种很有前途的新工具。与传统的海洋探测方法相比，地震海洋学具有许多优点，如提高横向分辨率，能够同时成像大片海洋，以及三维和时延成像的机会。本文介绍了几种重要的海洋现象的研究进展，包括测量温盐精细结构、成像水团边界、内波和黑潮洋流。目前地震叠加剖面没有被认为是真正的振幅处理，因此由叠后剖面的幅度计算的温度对比不准确。最后，本文介绍了地震海洋学的研究进展我们提出了使用新的真振幅偏移方法的想法，使结果在地震海洋学研究中更有意义。
Seismic oceanography is a promising new tool for studies of physical oceanography which uses conventional low frequency marine seismic reflection techniques.Compared to the traditional methods of probing the ocean,they offer several advantages,such as enhanced lateral resolution,the ability to simultaneously image large sections of the ocean,and opportunities for three-dimensional and time-lapse imaging.The paper introduces the research progress on several important oceanic phenomena,including measuring thermohaline fine structure,imaging water mass boundaries,internal wave and the Kuroshio Current.Recently the seismic stacked sections are not considered as true amplitude processed,so the temperature contrasts,which are calculated by the amplitudes of post-stack sections,are not accurate.Finally,we present an idea of using new true amplitude migration method which can make the result more sense in seismic oceanography research.
