Hi All
Cold water pumped to the surface will sink quite quickly. 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 understand that a test tank model will be shown
by Discovery Channel on 9 May at 10 pm EST in a programme called 'can we
hack the planet'.

Hi Folks,
The top/down approach is needed.
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.
Best regards,
Michael
