| Abstract: | The error of the sound velocity measured in water column is one of the most important factors influencing the accurate of bathymetry in the multi-beam echo sounder survey.The main influences on the sound velocity in the upper water column were researched.The dynamic draught of the transducer is also discussed.A synthesis application of temperature/salty/depth profilers which can measure the speed velocity and correct the draught in real time is proposed in order to improve the accurate of multi-beam echo sounder survey. |

| Keywords: | temperature/salty/depth profiler upper water sound velocity correction dynamic draught |
