“…Biofouling mainly includes acorn barnacles, mussels, calcareous tuberculosis, bryozoans and kelp. Non-biofouling factors include physical and chemical characteristics of seawater such as temperature, PH, dissolved oxygen and organic content, hydrodynamic conditions such as current speed, wave exposure, distance from shore and depth to water, and underlying characteristics such as material composition, color, roughness, immersion time, and exercise time (Vinagre et al, 2020). Non-biofouling and biological pollution are intertwined, affect each other and aggravate each other.…”
