[Coral-List] OTEC around coral reefs

[Kosmynin, Vladimir]

The thermocline in the tropical ocean, where the temperature changes from ~ +20oC to ~+5oC, is in between approximately 500 m and 1000 m. If one needs temperature below +20oC, have to take the water deeper than 500 m; pumping water from below 1000 m will bring very cold water ~+4oC.  There are local variations, indeed.

I bet if you go deep enough (likely 600 feet or more) it will be close to freezing.  That's true of most all of the world's oceans, so far as I know (with exceptions such as shallow continental seas such as the Arabian/Persian Gulf which has a maximum depth of around 295 feet).

You have to go many thousands of meters (not ft) to get to cold water at 4-6 oC which is way above freezing
