It is demonstrated that Fraunhofer lines in the solar spectrum will be filled in by inelastic scattering in the ocean. The relative depth of a Fraunhofer line, ij, defined as the ratio of the irradiance at the center of the Fraunhofer line to the background continuum, can then be used to measure the amount of inelastic scattering in the light field, i.e., by measuring ij, the relative contributions of elastic and inelastic processes to the light field can be deduced. An oceanographic instrument was developed to measure in-sifti inelastic scattering in the ocean. It utilizes a 1 m monochrometer, a CCD camera, and two irradiance collectors with a fiber optic light guide. Results of preliminary field measurements are presented and discussed.
