大水深海域における湧昇流発生構造物の開発

抄録

A new type artificial structure, in order to upwell the cold and eutrophic water from the sea bottom to the surface in deep sea, has been developed. Recently, some types of artificial upwelling generating structures have been proposed. Those structures can be seen as one of the coastal structures which are based on the sea bottom.
The proposed new structure is a kind of the big mooring artificial wall in the intermediate depth of deep sea. It can make more significant upwelling flows around the structure in comparison With other types proposed last. And it aims to be constructed in very deep sea for its structural characteristics.
