Estimating Detection Depth of Hydrodynamic Structures in Water through Above-Surface Optical Information Analysis

We describe a method for estimating detection depth of underwater hydrodynamic structures in above-water optical data. In situ and remote sensing data, as well as numerical modeling of the formation of upward radiation from the water surface are used for the design. The results of this study improve the interpretation of spectral data obtained from remote sensing of water color, which is associated with vertical variations in the content of optically active substances. Additionally, the method allows for determining the thickness of the surface layer within which some hydrodynamic phenomena can be remotely detected in the visible spectral range.
