摘　　要：卫星遥感数据同化技术已成为海洋学研究的一个有效手段。本文选取了日本以东黑潮流域作为研究海区,介绍了最优插值同化方法对海洋温度场和盐度场的分析,在此基础上对实验海区声场进行了研究。文中为了说明数据同化的优越性,利用WOA数据与其进行比较,体现了同化数据对真实场描述的可靠性。It has become a useful method of ocean research by satellite remote sensing assimilation technology. This paper plot out part of Kuroshio current, which is beside the east of Japan, to carry out the assimilation experiment, and introduce the research method which account the ocean temperature field and salt field by Optimal Interpolation. In these cases, the ocean sound speed field could be studied in the researching sea area. Of course, in order to introduce the superiority than other methods, the WOA data is compared with assimilation data, at last the assimilation data is tested credibility.
