Abstract:Ocean observation instruments are the basis for implementing operational marine observation activities. Their performance affects the accuracy of marine observation data and the quality of marine observation activities. The standard system of ocean observation was classified according to different observation platforms, and the basic parameters related to marine observation elements and their instruments are arranged from ocean observation standards. Then the general technical requirements of instruments are listed according to the characteristics of ocean observation activities, which is conducive to the standardization of the application of ocean observation instruments. The quality control methods of ocean observation data are summarized from the aspects of verification and calibration of ocean observation instruments and field comparison, which provides support for improving the quality of ocean observation data.
