Abstract

The Naval Ocean Research and Development Activity (NORDA) optical model, a Monte Carlo simulation of the radiative transfer equation, has been used for the first comprehensive optical modeling of clear ocean light fields. From this effort we propose a new optical parameterization of the clearest ocean water: the NORDA Blue Water Model. This parameterization (including molecular absorption of the water molecule, fluctuation theory scattering of the water molecule, large particle scattering, and water Raman scattering) provides the baseline for all other optical modeling of oceanic light fields. The predictions of the NORDA parameterization quantitatively account for the published data on radiant energy penetration into clear ocean water and the latest data from the state-of-the-art optics instrument of NORDA design, the POSSY (Particle Optical Sample System). The translation of the Monte Carlo output to field optical measurements is accomplished through the Three-Parameter Model of the submarine light field, which permits an exact solution of the integrated radiative transfer equation. From the Three-Parameter Model we can make quantitative estimates of both the nature of the radiance distribution field and the precise contribution of internal radiation sources to the submarine light field at any depth.
