Radiance in the ocean: effects of wave slope and raman scattering near the surface and at depths through the asymptotic region

Three investigations were conducted on the nature of the radiance field in clear ocean water. It is important to understand the sunlight intensity below the sea surface because this leads to an understanding of how ocean creatures navigate in shallow and deep water. The nature of the radiance field...
