摘要
海域水文资料的不断丰富和声速仪的广泛使用,推动了水深声速改正精度的提高。结合黄骅港水深测量数据,针对声速剖面测量与声速改正以及声速、器差、指标差等要素间的内在联系及相互影响予以系统阐述。
The accuracy of depth reduction has been improving with the continuous accumulation of hydrographic data and widely application of sound velocity profiler. This paper will systematically expatiate the interrelation and interaction between the factors of sound velocity, instrument correction and index etc.
