海洋内波活动对多波束测深影响因素的探讨

INFLUENCE OF OCEANIC INTERNAL WAVES ON MULTIBEAM BATHYMETRIC SURVEY

在多波束测深过程中,海洋内波对多波束测量精度产生影响的程度不同,由此会产生测量的地形出现起伏、扭曲等非正常现象。综合国内外的研究现状,本文大致阐述了目前海洋内波的研究进展,以及海洋内波成因和影响方式的研究程度,对海洋内波的主要基本特征有了一定程度的认识。基于实例分析,对试验海域海洋内波产生的原因进行了合理猜想。本文的分析研究对多波束测深工作具有一定的指导意义。

In the multibeam bathymetric survey,the internal waves of the ocean have different degrees of influence on the accuracy of multibeam bathymetric data.Abnormal phenomena,such as undulation and distortion of the measured terrain,are always observed.Summarizing the research status both at home and abroad,this paper presented an outline on research progress in ocean internal waves,espe-cially the research on the causes and effects of oceanic internal waves,and the basic characteristics of ocean internal waves.Based on the analysis of real cases,the causes of the internal waves in the testing sea are carefully discussed.
