| 摘 要： | 在对多波束测深声速剖面资料检查时发现,部分单位将海水压强简单地近似为海水深度,导致海水表层及浅水处的声速实际值受影响较大。分析了多波束测深声速剖面资料存在的若干问题,引入国际上由海水压强向深度转换的新实用模型,对存在的问题进行了纠正,基于实测声速剖面资料进行了试验性验证,提出了使用多波束测深声速剖面时需要注意的几个问题。

| Abstract: | There are some improper operation about conversion between sea pressure and depth when inspectingon the sound velocity profile data of multibeam sounding.Thus the sound velocities of the surface layer and theshallow water are influenced.So a new international practical model about conversion between sea pressure anddepth is introduced and some detailed analyses are made.Some advices on the actual use of sound velocity profileare put forward at last. |
