Abstract

In studying light and image transfer in coastal waters the influence of bottom reflection is as significant as scattering and absorption phenomena. In these cases a knowledge of the reflective properties of different types of bottoms is very important. At present, little is known about these properties. We present results of experimental spectral measurements of different kinds of sedimental material such as sands and clays, both major components of coastal water bottoms. We have determined the spectral index of refraction from measurements of the optical spectral signatures of various clays and sands, as the represent the most common bottom components found in coastal waters. The measured optical spectral signatures and the associated complex indexes of refraction are presented. This preliminary study should provide insight on improving the inverse problem algorithm for extracting the spectral index of refraction. This spectral information can then be used as input into radiative transfer models which include the ocean bottom.
