Abstract
To remedy the various environmental degradations, it is necessary for its factor to clear widely in Ariake Bay. The cluster analysis as to the temporal variation pattern of dissolved oxygen and the principal component analysis as to its spatial variation pattern were carried out in order to group the dissolved oxygen at the bottom in summer, 2007 in Ariake Bay. As a result, the dissolved oxygen was grouped to 4 patterns by both analysises. The cluster analysis suggested that the continuance of hypoxic water differed from each groups. The principal component analysis suggested that the development- disappearance process of hypoxic water was captured widely.
