联合WOA2018温盐模型及实测温盐资料重构全深度声速剖面(三):声速剖面处理

Reconstruction of the Full-depth Sound Speed Profile with World Ocean Atlas 2018 and in-situ Temperature and Salinity in Sea Water,PartⅢ:Processing of Sound Speed Profile

声速剖面是否准确和完整对多波束测深具有重要意义。无论是在作业现场还是在数据后处理阶段进行声速改正均要求首先应对声速剖面进行完善的处理,以确保声速剖面的内符合精度。结合相关涉海部门使用的声速采集设备类型多样化的现实,针对声速剖面处理中存在的多样化格式数据的读取、多个温盐或声速剖面间的比测评估、深度不完整剖面的重构、实测值探测深度处温盐模型值的约束、多样化声速成果数据格式的生成等开展了研究,并开发了相应的软件模块。

The accuracy and perfection of sound speed profile is of great significance to the multibeam sounding.In order to ensure the internal accuracy of the sound speed profile,the sound speed profile must be processed first whether in-site or in the data post-processing stage.There is a reality of various types of sound speed acquisition equipment used by relevant departments involved in the sea are.In this paper, the reading of diversified data formats,the comparative evaluation of multiple temperature and salinity or sound speed profile,the reconstruction of incomplete depth profiles,the constraint of temperature and salinity model values at the detection depth of measure values,and the generation of diversified sound speed data formats are studied.And the corresponding software module are developed.
