摘要
基于经核实的多个常用声速计算模型开展了精度比对,提出了全球海域最优声速模型选定的基本要求,证明了Del Grosso、Chen-Millero、C.C.Leroy2008及Coppens式适用性更强。优化了现行海道测量规范中由水文资料计算声速改正数的方法,设计并开发了适用于全球海域水深测量的声速剖面计算及改正新软件。
Based on the precision comparisons of the commonly-used sound velocity models, the base requirements of the optimal sound velocity model in global ocean are given. Moreover, the better applicability will be obtained by the following models, such as the Dell Gross, the Chen-Millero, the C.C.Leory 2008 and the Coppens.In addition,the sound velocity correction calculating models are improved in the actual specifications for hydrographic survey.The sound speed profile calculating method and software are designed and developed for the marine sounding in the global ocean.
