[0002] Environmental disasters in water areas occur frequently, which poses a great threat to human society and natural ecosystems. In order to effectively monitor and warn these disasters, a marine optical buoy capable of continuously, real-time and accurately obtaining water environmental information is needed. The marine optical buoy is a customized, long-term unattended real-time online marine optical observation platform specially used for continuous observation of the optical properties of the sea surface, seawater surface layer, euphotic zone and even seabed. It has important application value in water color remote sensing field radiation calibration and data authenticity verification, marine scientific observation, nearshore marine environment monitoring and marine military science. However, the existing water optical buoy still has many defects in actual use. For example, the existing buoy generally adopts a disc shape. The disc-shaped buoy has strong wave-following characteristics and is easily affected by wind and waves to produce large swings, resulting in distortion of optical measurement data.
