Research Abstract

Transparency increased in the entire Ariake Bay with an average of 50% during the last 30 years. The area with increased transparency corresponded with the area of increased number of red tides. The transparency can be expressed quantitatively in terms of surface inorganic suspended matter and chlorophyll a. The increase of transparency seems to be caused by decrease of about 10 mg L^<-1> of suspended matter. Primary production was linearly correlated with euphotic zone depth, and the ratio of increase of transparency should result increase of same ratio of primary production. These results indicate that the increase of transparency is one of the causes of increase of red tide in Ariake Bay.
