为了对渤海湾的环流形态有一个准确的认识，对渤海湾进行了一次较为全面的海流调查。这次调查以Ｌａｇｒａｎｇｅ观点为指导，采用３种方法：海流计在固定站位连续测流；漂流板轨迹观测和“人工水母”测底层流。本文分别介绍这三种方法及观测过程，并分析得出了渤海湾Ｌａｇｒａｎｇｅ余环流型大致是顺时针的结论 In order to have an accurate understanding of the circulation pattern in Bohai Bay, a more comprehensive current survey was conducted in Bohai Bay. Under the guidance of Lagrange, the survey uses three methods: continuous flow measurement at a fixed station by a flow meter; observation of drifting track and bottom flow by artificial jellyfish. In this paper, we introduce the three methods and the observation process separately and conclude that the Lagrange residual circulation pattern in the Bohai Bay is roughly clockwise
