In this report we present the results of running Monte Carlo simulations on the Connection Machine CM-5E to study the behavior of laser propagation in the ocean. We developed an advanced hydrologic radiative transfer model to estimate the effective depth of a laser imaging system in various ocean environments. This model simulates a flat ocean surface. The effective depth is defined as that at which a six-pixel wide disk target can no longer be detected in the upward irradiance field at the ocean surface. Simulations showed that the effective depth was inversely proportional to the total attenuation coefficient.
