Paper Abstract

The distribution of irradiance on the sea surface due to an isotropically emitting point source in the water is computed using Monte Carlo techniques for a pure Rayleigh scattering ocean and for a more realistic ocean exhibiting strong forward scattering. The resulting irradiance distributions show at least two regimes. The first is for the source relatively close to the detector, in which the irradiance is more strongly influenced by geometry than by the water's optical properties. The second is for large separations between the source and the detector in which case multiple scattering is dominant. In the latter regime, the irradiance is relatively independent of the source depth and exhibits a near-exponential behavior with distance along the surface. The exponential decay coefficient in this diffusion-like regime is very nearly equal to the decay constant of the asymptotic light field for a homogeneous ocean with the same optical properties.
