Based on in situ measurements of the hydrological and bio-optical characteristics of the marine water, an analysis was made of the variations of the simulated remote sensed reflectance spectra of the sea during the passage of internal waves in the shelf zone of Peter the Great Bay. It has been shown that color indices and remotely determined concentrations of chlorophyll-a have the greatest contrast for remote observation of the manifestations of internal waves in the marine column. The optimal spectral range for satellite identification of the manifestation of internal waves is 440–500 nm. The obtained optical characteristics can be directly used to analyze the period of oscillations of internal waves and their automatic identification in satellite images. The position of the crests of the internal waves can be smeared or shifted, and for its estimation, as well as for estimating the amplitude, it is necessary to solve the inverse problem of remote sensing of the color of the sea, taking into account regional hydro-optical characteristics and the unstable stratification of optically active components in the sea mass, using data from hydrophysical modeling.
