Abstract

We propose a new indicator, the Red Tide Index, which permits assessment of spatial and temporal scales and impacts of red tide. By examining temporal and spatial variations of this index across the entire Seto Inland Sea area, we can assess regional characteristics of its coastal and offshore areas. The index for Osaka Bay was the highest in the sea, but it has markedly declined in recent years. This suggests that water quality in the bay has recovered. In areas with high (low) Red Tide Index density, dissolved oxygen concentration in the bottom layer is low (high).
