摘要: Abstract Artificial upwelling can lift nutritious deep ocean water to sunlit layer, as a result, it is able promote primary production and being paid more attention all over the world. Kinds of artificial method have been invented in recent years, however, few them fulfill requirement desired flow rate balanced budget. The design an air-lift device powered by hybrid energy system presented this paper, where solar, wind wave exploited together induce upwelling. preliminary results open sea trial lasted for 7 days demonstrated that assembled floating platform with surface area 12.5 m 2 4234 m 3 seawater from than 20 m depth. In particular, operation based on optimal dispatch strategy showed unit cost induced only 0.005 US $/m . work paper constitutes step towards development advanced used
