This paper examines the formulation of the different methods of solving the one-dimensional transient radiative transfer equation for ocean remote sensing. This work is particularly helpful in determining school of fishes inside the ocean for commercial purpose. In this technique a pulsed laser is focused into the ocean, and the time-dependent back-scattered flux is measured at different depths inside the ocean. A large number of parameters such as the spatial and temporal variability of optical properties inside the ocean, ocean depth, type of ocean water, presence of biological matters, etc. can significantly affect the radiative transport through oceans. But since the emphasis of the work is on the scattering phenomenon, important parameters associated with it, namely the scattering albedo and scattering phase function distribution, are considered in detail in this paper.
