Environmental measurement of Dokai Bay surrounded by a Japanese leading heavy and chemical industrial area is evaluated as one of the success instances from the heavy industrial pollution which degraded the bay's ecosystem to be called "the dead sea". After the restoration, the bay newly encounters the water pollution including man-made chemical contamination and eutrophication. We start the comprehensive investigation and research reviving the rich aquatic ecosystem.
