2. Description of the Related Art In recent years, in a closed inner bay, eutrophication has progressed due to drainage from living, agriculture, industry, etc., and in summer the density has decreased due to an increase in sea surface temperature.
A thermocline occurs and a stratified state occurs. Then, the dissolved oxygen is consumed by the decomposition of the organic matter deposited on the seabed, thereby forming anoxic eutrophic bottom water. When the offshore wind blows in this state, an offshore current is generated, the bottom water rises, causing blue tide and red tide, causing damage such as death of fish and shellfish, which is an environmental problem.
