Measuring and interpreting the optical properties of seawater has become and will still be a challenging research direction for oceanography. The development of marine optics has kept pace with the updates and advances in field measurement technology. The apparent optical properties of the water body are determined by the inherent optical properties of the seawater and the distribution of the radiation fields in the sea, and phytoplankton, suspended sediment and dissolved matters can absorb and/or scatter natural light from a solar system, so that the light field under water and the upward radiance spectrum crossing a water-gas interface can be deeply influenced. The method has the advantages that the optical characteristics such as the water-leaving radiance or the remote sensing reflectivity of the water body with high precision are obtained, and then the concentration parameters of water color elements and related matters of the water body are obtained through inversion of the spectrum, so that the method can serve the monitoring, classification, evaluation, predictive early warning, the study of climate change and the like of the water environment and the water ecology finally.
