| Abstract: | Two kinds of methods for measuring sound speed of seafloor sediments which are in-situ measurement technique and laboratorial measurement technique are introduced at first.Secondly,the sound speeds measured by in-situ equipment and by laboratorial technique in the middle area of the Southern Yellow Sea are compared in detail.The result indicates that there are large differences between in-situ and laboratorial sound speeds.Based on the differences,the influence of sediment temperature and hydrostatic pressu... |
