Description of the Related Art Today, artificial upwelling of seawater (deep ocean water), which has cleanliness, eutrophication, and low water temperature and is out of reach of the sun's rays due to depletion of marine resources and deterioration of aquaculture environment of cultivation and fisheries. As a result, the development of effective utilization technology for use in facilities constructed near the coast is underway (land production type). According to this method, an intake pipe is laid along the seabed from the coast, and deep sea water of a predetermined depth is artificially upwelled by a pump provided near the coast. On the other hand, a deep sea water intake pipe from an offshore work boat is dropped and discharged directly into the sea to promote the growth of phytoplankton, and a trial to construct a structure on the sea floor and cause topographic upwelling. Etc. have been promoted.
