%X In this paper, we put forward a new method of measuring the in situ velocity of marine sediments and introduced the in situ measurement system of marine sediments. The system was tested in Qingdao offshore area. We compared the velocity of different sea sediments and analyzed the correlation between mean grain size and velocity by regression analysis. The results indicated that the different sediments had different velocities and the sediments with coarser grains had higher velocity. The results were accurate by contrast with previous research. The research in this paper verifies that the measurement system can measure the velocity quickly and accurately.
