摘要
当前温盐深剖面测量仪器发展趋势呈现多样化和国产化特点,但相应的数据预处理研究往往仅针对某一特定仪器,缺少对处理原理、步骤顺序和质控原则的基础性探讨与通用性总结。基于这一现状,利用CTD、XCTD、Glider等多种仪器实测数据,结合传感器工作原理,系统梳理了温盐深剖面数据预处理的基本步骤和原理方法,并基于实测数据质量控制效果,对数据预处理中各步骤的实际作用及使用原则展开分析,阐明了各步骤间的相互影响和注意事项,形成合理的处理流程建议,旨在为海洋调查和数据标准化工作提供有益参考。
The current development trend of the temperature-salinity-depth profile measuring instruments is diversified and domestic,but the corresponding data pre-processing researches are mostly targeting a particular instrument,as well as general discussion and summary on the processing principle,the sequence of steps and the principle of data quality control are lacking.Using the measured data of CTD,XCTD,Glider and other instruments,combined with the working principles of sensors,the paper combed the basic steps and principles of the data pre-processing of the temperature-salinity-depth profile.Based on the quality control effect of measured data,the actual function,reasonable sequence and use principle of each step are analyzed in the pre-processing,and the mutual effect and attentions among different step are cleared,which support process optimization and provide useful reference for marine investigation and data standardization.
