Artificial Upwelling of Deep Seawater Using the Perpetual Salt Fountain for Cultivation of Ocean Desert

摘要: Deep seawater in the ocean contains a great deal of nutrients. Stommel et al. have proposed notion “perpetual salt fountain” (Stommel al., 1956). They noted possibility permanent upwelling deep with no additional external energy source. If we can cause to upwell extensively, achieve an farm. We succeeded measuring velocity by experiment Mariana Trench area using special measurement system. A 0.3 m diameter, 280 long soft pipe made PVC sheet was used experiment. The measured data, verification experiment, and numerical simulation results, gave estimate 212 m/day.
