We have developed a Monte Carlo program that can account for Raman scattering in the ocean when polarization effects are not considered. The program is capable of coupling an inhomogeneous atmosphere to an inhomogeneous ocean through a dielectric interface. We have studied the filling in of both the 486-nm Hβ and the 518-nm Mg Fraunhofer lines caused by Raman scattering in the ocean. The amount of fill varies with solar zenith angle, angle of view, depth in the ocean, and magnitude of the cross sections. By monitoring the shapes of Fraunhofer lines we can learn a great deal about the relative importance of this inelastic process in oceanic optics.
