Autor: Kiyoshi Takikawa, Yoshihiro Sonoda, Chiharu Aoyama, Takashi Saito

Publikováno v: Journal of Japan Society of Civil Engineers, Ser. G (Environmental Research). 67:150-169

In recent years, the Ariake Sea environment has become severely degraded, resulting in changes in biota, a marked overall decrease in the number of species, frequent outbreaks of red tides, and the deterioration of water quality and the sediment envi
