This disclosure is to mitigate the effect of coastal upwelling on coral reefs using an artificial downwelling system injecting warm water into the upwelling jet and disrupting it. Another purpose of this disclosure is creating favorable climate conditions for the development of residential communities and the associated infrastructure in the currently uninhabitable coastal deserts on the eastern ocean boundaries. An artificial downwelling can consist of a cluster of wave-inertia pumps and a modified Sea Water Air Conditioning (SWAC).
