水下滑翔机数据管理

Data Management of Underwater Gliders:a Review

近年来,随着水下滑翔机技术的深入发展,其在各国海洋观测与探测系统中发挥着重要作用,由此积累了大量的观测数据,构建了相当成熟的数据管理框架体系,并将逐步形成标准的业务化流程。我国在此方面开展的工作尚处于起步阶段。基于此,文中综述了全球海洋观测系统(GOOS)计划对水下滑翔机数据管理的需求,介绍了美国综合海洋观测系统(IOOS)、澳大利亚综合海洋观测系统(IMOS)和欧洲水下滑翔机观测组织(EGO)等已经形成的水下滑翔机业务化数据管理系统,梳理总结了水下滑翔机数据管理在工作流程创建、数据格式和元数据、质量控制等关键技术方面的核心内容,同时提出了水下滑翔机常见搭载的温盐深传感器(CTD)、光学类和生化类传感器的数据质控要点。最后,从我国水下滑翔机的应用现状和发展角度,对水下滑翔机数据管理未来的工作进行了讨论,并在数据质控、业务体系建设等方面提出了具体建议。文中的工作可为我国水下滑翔机观测数据的科学管理及应用提供参考。

This paper reviews the requirements of the global ocean observing system(GOOS)program for data management of underwater gliders,and introduces some present data management systems such as the U.S.integrated ocean observing system(IOOS),the Australian integrated marine observing system(IMOS),and the European gliding observatories(EGO);and then summarizes the core contents of underwater glider data management,concerning workflow creation,data format and metadata management,quality control,etc.The key points of data quality control of multidisciplinary sensors,including conductivity-temperature-depth sensor,optical sensor and bio-chemical sensor,are introduced.Moreover,the future work for data management of underwater gliders is discussed from the perspective of current application and development of underwater gliders in China,and suggestions for the data quality control and operation system are offered.This work may provide reference for scientific management and application of underwater glider observation data in China.
