Paper Abstract

A technique is described here in which the polarization properties of elastically scattered light and the unpolarized nature of excited fluorescence are utilized to extract white light induced chlorophyll fluorescence component from the reflectance spectra of sea water. This technique was tested and shown to be effective for retrieval of the chlorophyll fluorescence in the 685 nm regions from reflectance of water dominated by chlorophyll pigments. Simulations based on Mie scattering and semi-empirical model of reflectance also support the validity of this approach. In simulations for a wide range of chlorophyll concentrations from 5 to 50 mg/m3, the extracted fluorescence spectra through modeling matches very well with the input synthetic chlorophyll fluorescence. Compared with the traditional baseline subtraction method, this technique works for both case I and case II waters and the extracted fluorescence amplitude shows higher accuracy.
