CHARACTERIZATION OF BENTHOS DISTRIBUTION AND SEDIMENT ENVIRONMENT IN THE YATSUSHIRO SEA

Abstract

 This study made clear that the Yatsushiro Sea can be divided into seven sea areas by examining the next factors ; (i) time-series variation of physical and chemical items of sediment and benthos distribution, (ii) relevance of nutrient of sediment and sea surface culture, (iii) relevance of mud content and streamflow of the Kuma River, (iv) relevance of mud content and mean currents of undermost layer, (v) shields number, and (vi) clustering of physical and chemical items of sediment and species of benthos.
