实验室盐度计与船载CTD海上比测实验评价方法
Evaluation method for intercomparison test between laboratory salinometer and ship-borne CTD during the oceanographic cruise
摘要
Abstract
To improve the credibility of cruise data,the intercomparison test of laboratory salinometer with ship-borne CTD has become a standard procedure.However,how to scientifically evaluate the reliability of the intercomparison itself and subsequently guide data correction remains a critical issue to be addressed.Accordingly,this study establishes an uncertainty evaluation framework to reveal the variation mechanism of salinity comparison bias with depth.A quantitative evaluation system—comprising a reliability factor(α),a consistency test factor(β),and a correctability judgment factor(γ)—was designed.This system enables systematic assessment of intercomparison reliability and effective diagnosis of instrument stability,and guided data correction.The evaluation method proposed in this study provides a theoretical basis and a technical pathway for optimizing intercomparison schemes,nationalizing survey resource allocation,and enhancing the operational efficiency of research vessels.关键词
