A method for analysis of satellite image in visible light was developed for making a document and teaching material of new environmental science. Since environmental contamination manifests especially in fine hue changes, we newly developed a hue and contrast emphasis method of satellite image. We investigated the satellite photograph by

As a result, we could not find the influence of condensate dumped into the sea, it is found that there is a possible sea surface black band. It was also found that the eutrophication of the East China Sea extends near the Japanese exclusive economic zone (Exclusive Economic Zone, EEZ), sometimes the polluted seawater reaches the western coast of Kyushu island.
