[Coral-List] OTEC around coral reefs

[Douglas Fenner]

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).

"mitigating climate change is the critical wedge to set coral reefs on a
recovery trajectory"  Duarte et al 2020 Rebuilding marine life Nature

"Already, more people die  <http://www.nws.noaa.gov/om/hazstats.shtml>from
heat-related causes in the U.S. than from all other extreme weather events."

and must be addressed by the global community if reefs as we know them will
have any chance to persist."  Williams et al, 2019, Frontiers in Marine
