A novel design and application of anti-biofouling system of buoy sensor based on sampling measuring method

Abstract

Abstract The stability and reliability of sensors significantly influence the quality of the ocean buoy data. The long-time submersion of sensors increases the risk of biofouling, leading to a decline in data quality and malfunctions. To resolve this problem, this paper presents an automatic seawater sampling and drainage system based on the formation principles and characteristics of biofilms. The sensor is exposed to seawater only during the measurement cycle, minimizing the contact time with seawater. This disrupts the conditions for the formation and growth of marine microorganisms. A comparative experiment was conducted at a shore station by using different methods, and the measurement data were analyzed. The study demonstrated the applicability and efficiency of the proposed method compared to traditional methods in measuring temperature, salinity, and chlorophyll. In conclusion, we point out the disadvantages of the method and emphasize future research.
