CTD海上剖面测量性能综合评定方法研究

随着国产温盐深剖面仪（Conductivity-Temperature-Depth profiler，CTD） 测量性能的不断提高，其使用范围和规模也逐步扩大，需要规范CTD 海上剖面测量性能评定方法。在威海附近海域开展基于锚泊式平台CTD 海上比对试验，通过改变同架比对CTD 数量、引入相关系数和平均差数据处理方法研究海上比对试验效果，提出以精准度和灵敏度为目标层的CTD 海上剖面测量性能评价指标体系，实现了对被测CTD 海上剖面测量性能相对全面的评价，准确量化了被测CTD 在实际海洋环境中的剖面测量性能，为国产CTD 海上剖面测量性能的优化提供依据。

Research on Overall Evaluation Method of CTD Marine Measurement Performance

With the continuous improvement of the measurement performance of domestic CTD, it爷s using scope and scale are gradually expanding, and it is necessary to standardize the evaluation method of CTD offshore profile measurement performance. Offshore comparison test base on moored platform was conducted on the sea area near Weihai, by changing the number of CTD compared on the same craft and introducing correlation indicator, a performance evaluation method for CTD offshore profile measurement base on accuracy and sensitivity was proposed, comprehensive evaluation of the performance of CTD offshore profile measurement was achieved, the profile measurement performance of domestic OST CTD in actual marine environments was accurately quantified, provide a basis for optimizing the performance of domestic CTD offshore profile measurement.
