[Coral-List] OTEC around coral reefs

[Dennis Hubbard]

Is there more information on the depth from which water will be sourced.
Looking at the marginal charts I could find on line, the temperatures may
not be as cold as at 5,000 meters north of St. Croix, but, as Alina stated,
the goal is typically to bring up colder deep waters... and these typically
carry LOTS of nutrients. They looked at this on St Croix eons ago
specifically to bring up nutrients for onshore aquaria to raise shrimp at a
University of Texas facility on the north shore. To draw from the old Jimmy
Buffet classics, these "scientists" were "running from the IRS".
