Abstract
We have further developed and improved the prototype oceanic Fraunhofer line discriminator by using a well-protected fiber-optic-wire cable and in-water electronic housing. We conducted a series of in situ measurements in clear ocean water in the Florida Straits. By comparing the reduced data with the Monte Carlo simulations results, we verify the Raman scattering coefficient B r with an excitation wavelength at 488 nm to be 2.6 x 10-4 m-1 [Appl. Opt. 29, 71-84 (1990)], as opposed to 14.4 x 10-4 m-1 [Appl. Opt. 14, 2116-2120 (1975)]. The wavelength dependence of the Raman scattering coefficient is found to have an insignificant effect on the in-water light field. We also discuss factors that lead to errors. This study can be used as a basis for inelastic light scattering in the radiative transfer theory and will allow other inelastic light, e.g., fluorescence, to be detected with in situ measurements.
