深海地形调查中声速剖面质量控制方法

Quality control method of SVP data in deep sea topographic survey

通过对深海多波束地形调查中实测声速剖面数据质量的研究,探讨声速剖面仪检定以及实际应用中的质量控制措施。利用抛弃式温盐深仪和同海区国际剖面浮标的剖面数据,对声速剖面仪实测数据进行比对,分析声速剖面数据的固定偏差或线性偏差,完成声速剖面数据修正,提高了实测声速剖面数据的应用水平,为大洋专项调查中声速剖面数据的质量控制,提供了一种有效参考方法。

Sound velocity profile is an important content used to correct the sound propagation distance in water depth surveys and acoustic surveys.This article discusses the sound velocity profiler verification and field application through the quality control research of the field data in the deep-sea survey.By using XCTD and Argo buoy profile data in the same sea area to compare the measured data of the sound velocity profiler,analyzing the fixed deviation or linear deviation of the field data,and completing the correction,this article provides an effective reference method for the quality control of the sound velocity profile data in the deep-sea survey,and effectively improves the application quality of the measured sound velocity profile data.
