多参数CTD测量在富钴结壳环境调查中的应用

传统温盐深测量及采水作业中，通过水样现场化学测试获取水体附加参数的方法具有低效、不适宜气体测量、结果分辨率低等缺点。结合前人在附加传感器应用上所做的工作，借鉴国外海洋物理调查的先进经验，提出将水样现场化学测试与传感器方法相结合的多参数CTD测量模式。西太平洋麦哲伦海山群M海山的应用试验证明，该模式能满足富钴结壳环境调查的需求，更加高效、准确、精细地揭示多项环境参数特征。

Application of multi parameter CTD measurement in the environmental investigation of cobalt-rich crust

The traditional temperature, salinity and depth measurement and water sampling obtained additional parameters of water bodies through in-situ chemical tests on water samples, which is not suitable for gas measurement and has poor accuracy and low resolution. Based on previous researches on the application of additional sensors and the advance experience of foreign physical oceanographic survey, this study proposed a multi-parameter CTD measurement model combining in-situ chemical tests with sensors. The application in the M seamount of the West Pacific Magellan Seamounts indicates that this model can meet the environmental investigation demands of cobalt-rich crust, and can also get many environmental parameters with greater efficiency, accuracy and precision
