Artificial sea mount

摘要

In an artificial sea-mount constructed by piling up a plurality of block bodies on the seabed to vertically mix water mass in a peripheral sea area using a tidal current, ocean current, and internal wave in that sea area, a cone array formed from three or more cones is constructed linearly on the seabed, and the vertex interval between the cones is set to 0.75 times to 2 times the bottom radius of the cone. It is possible to generate an upwelling current even in the deep sea area by inverted triangle-shaped gaps formed between the cones and the conic surfaces of the cones, and thus obtain effective upwelling flux.
