Abstract
A model1'2 which describes the transfer of irradiant light in water is used to predict the fluorescence response ofthe water surface reflectance under solar induced or an artificial light source such as a laser. Formulations for the estimation of wavelength dependent fluorescent coefficients. The techniques allows the description ofa fluorescence reflectance response in deep and shallow waters with various bottom reflectance signatures such as submerged vegetation, corals and sand. Recent advances in the model are presented for obtaining wavelength dependent fluorescence spectrum responses from the solutions of the two flow equations following the procedures developed by Bostater1'2'3. Synthetic or modeled signatures are presented using in-situ data from the Space Coast of central FLorida, USA and the southeastern Atlantic waters near Beaufort, South Carolina. The synthetic or modeled signatures are also dependent upon the attenuation length of the water based upon knowledge ofthe diffuse attenuation coefficient (k), the beam attenuation (c) or the absorption coefficient (a). The model has potential applications for helping to select remote sensing optimal channels or bands useful in near nadir viewing geometry ofestuarine or coastal water columns overlying shallow sand, submerged vegetation, or coral reefs. The analytical solution to the two-flow equations developed by Bostater1'2 have transferability to complex but important water quality detection problems that can be assisted using fluorescence processes.
