Research on the quality control of nutrients data for the aquatic ecological on-line monitoring system of marine station

Abstract

The coastal marine ecological environment problems have led to the development and application of the aquatic ecological on-line monitoring system of the marine station. To improve the whole-process quality assurance and control system of marine automatic monitoring and ensure the accuracy and continuity of monitoring data, in this paper, the quality control and maintenance of the nutrients probe analyzer (NPA) in the aquatic ecological on-line monitoring system of Xiaomai Island Marine Environment monitoring station were studied by means of instrument performance audit, standard curve inspection and calibration, standard sample inspection and artificial synchronous comparison. The research results show that the overall performance and operating status of NPA are stable, and the monitoring data can basically truly reflect the current status of nutrients in seawater. The research in this paper has proved the reliability of the relevant quality control methods and provided a basis for the operational monitoring of the aquatic ecological on-line monitoring system of marine station.
