A research team from Nagasaki University will place a hose on the bottom of Omura Bay in Nagasaki Prefecture to pump in air and ameliorate the bay’s severe oxygen deficiency, restoring the natural environment. That deficiency has resulted in a serious deterioration of water quality. Omura Bay is a relatively isolated body of water with poor water circulation. Water quality began worsening in the 1970s when the bay was used for the disposition of waste water. The university says it is unusual for water purification efforts to be applied to an entire bay.
