Ocean upwelling system utilizing energy of surface waves

The upper ocean is an important component of climate and climate change. The heat capacity of only a few meters of the ocean is equivalent to the heat capacity of the entire atmosphere. (Solar radiation and IR balance in the atmosphere are of course major factors as well.) A large amount of cold water is available below the thermocline. Artificial upwelling devices can bring cold and nutrient rich water from below the thermocline, increase bio-productivity and cool down the sea surface and the air above. An analytical model and computational fluid dynamics simulation indicate high efficiency of the system. Wave-driven upwelling devices can modify climate on a local scale, and possibly help mitigate hurricanes to some extent.
