摘　　要：高精度的温盐深测量仪(Conductivity-Temperature-Depth,CTD)是实现海洋动力环境背景要素长期连续观测的最重要的海洋观测设备之一。尽管国产CTD的研制已经取得了一系列应用成果,但是基于深海潜标平台的多深度的CTD比测工作仍然较少。本文基于“十三五”期间国家重点研发项目研发的准实时传输潜标平台所搭载的三组国产CTD与进口的CTD所获取的数据进行了详细的比对分析。在潜标系统较为稳定的时刻,两者的平均温度差最小为0.001℃,平均盐度差最小为0.001 psu。比测结果表明:国产CTD在复杂的深海海洋环境下所测得的温盐深数据具有较高的稳定性与可靠性。国产高精度CTD的研制与应用对提高我国海洋现场连续和长期的观测能力,促进海洋基础科学研究的发展具有重要作用。A high-precision temperature-conductivity-depth(CTD)is one of the most important ocean observation instrument for long-term continuous observation of the background elements of the ocean dynamics.Although the development of CTD has achieved some application results,there are still few comparative measurements with multiple depths and long time series based on subsurface mooring platforms.This paper presents a detailed analysis of the data obtained from three sets of CTD and SBE CTD based on the quasi-realtime transmission subsurface mooring platform developed by National Key Research and Development Project during the 13th Five-Year Plan period.At moments when the mooring system is stable,the average difference in temperature and salinity between then with a minimum of 0.001℃ and 0.001 psu,respectively.The results of the comparison measurements show the stability and reliability of the data measured by the China CTD in the complex deep-sea marine environment.The development and application of the China high-precision CTD will play an important role in improving the continuous and long-term observation capability of our marine filed and promoting the development of basic marine science research.
