The purpose of this research is to develop a procedure for extracting information on the water quality of sea and lake from multi-spectral satellite images. First, the condition of the red tide appearance in Wakasa Bay was obtained using chlorophyll-a concentration and sea surface temperature. The next target is to evaluate the water quality using satellite spectral images. As the first step of the research, a controlled laboratory experiment has been conducted to measure the spectral reflectance of samples obtained from sea and lake in order to determine the relationship between concentration of principal components of the water and the spectral reflectance.
