Most coral reefs have a lagoon which is like a bowl. The lagoon protects also from sharks coming from ocean to lagoon. The coldness would be absorbed by corals. If the cold water is pumped near coast by the time it reaches outer reach of lagoon it will have warmed and done its job by cooling the corals. The only place where the cold water sinks is corals themselves and those we are just trying to save from heat.

It is also possible to pump warm surface water down at places up stream of the coral with all the energy coming from wave action. I can send a paper to anyone who asks.

I would like to point out that one of Greg Rau's early papers was on the subject of pumping deep cold water up to coral reefs to protect them from heat. It is now known that artificial upwelling will also bring up nutrients and CO2, neither of which are needed by the coral. As such, if that nutrient and CO2 rich water is first conducted through an enclosed marine biomass operation, leaving no more than cold water for the coral, Greg's idea becomes viable. MCB and Brightwater should both play an important role, in concert with confined marine biomass production, in protecting coral reefs. The sale of the marine biomass/biochar should be able to pay for both MCB and Brightwater operations.
