In order to determine the behavior of red tide distribution by satellite remote sensing, we found out that the optical properties of Tokyo Bay significantly changes in terms of measured AOP (apparent optical properties) and IOP (inherent optical properties) in field observation. Based on the spectrum variation of measured reflectance, we developed the estimation model of high concentration of Chlorophyll-a (Chl-a). By applying the developed model to satellite images, the spatial variation of high concentration of Chl-a in the bay was discussed in this paper. As a result, Chl-a was gradually increasing from the coast of the bay. It was found that the increment of Chl-a is mainly dependent on the spatial variation of temperature when wind was weak and solar radiation was high.
