Study of bubble population influence on the diffused blue-green light transmission in the upper ocean layer

Under wind condition, horizontally homogeneous stable layer of bubble population is generated in the upper ocean because of wave breaking. Meanwhile, the air-sea interface is rough according to wind blowing. In this paper, Monte-Carlo method is employed to study the transmission process of diffused blue-green light in the upper ocean layer. On the basis of absorption and scattering by the natural water, the influence of bubble population which varies with wind speed and decreases with depth exponentially under the effect of gravity, and also the rough surface, are analyzed. The results show that the rough sea surface dominates the transmission process of diffused light. The influence of bubble population enhances at high wind speed. The transmission characteristics varies with wavelength.
