Abstract

Transport theory methods can be applied to optical oceanography to compute the spatial dependence of irradiance and scalar irradiance of the light field from an isotropic point source deep within a spatially uniform ocean. The infinite medium Green's function for plane geometry is used to obtain scalar and plane irradiances. The isotropic point source expressions can be obtained from the isotropic plane source solutions using plane-to-point transformations. Then the analytical solutions for the diffuse attenuation coefficient and the mean cosine far from the isotropic point source are obtained. The problem is numerically solved for the Henyey-Greenstein phase function. © 2006 IOP Publishing Ltd.
