Inverse estimation of multi-substance concentration of coastal turbid waters based on a four flux model

A method based on a four flux model has been developed to accurately estimate multiple-substance concentrations in seawater for the case the backscattered light from the sea bottom is not ignored because of the shallow depth. Three selected substances were assumed to be in the sample area, and the concentration of each substance was estimated from an aerial MSS image. The results estimated were compared with sea data, and the concentrations were estimated much better than that of our previous model in which the sea bottom was ignored.
