miniSVP声速剖面仪在测深声速改正中的应用

Application of MiniSVP Sound Velocity Profiler in Sound Velocity Correction

以珠江流域水道数据为基础,采用英国Valeport公司生产的miniSVP声速剖面仪直接测量水体的剖面声速,并计算了声速误差对水深测量精度的影响。结果表明,声速误差带来的深度改正是影响测深精度的一项重要因素。

In this paper,the sound velocity of the water body can be measured by miniSVP sound velocity profiler produced by the British Valeport company directly based on the data of Zhujiang River channel.And the influence of sound speed error on the accuracy of water depth measurement was calculated.The results show that the depth correction caused by sound velocity error is an important factor which can affect the accuracy of water depth measurement.It is not advisable to use the designed sound velocity to measure the depth of water.
