I'll be divng in the Florida Keys this very week in water reported to be
near 87 degrees. I never use thermal protection in waters this warm.
In the Persian Gulf, water temps get very high, maybe ninety degrees or
more. It gives ships steam plants great problems because the injection
temp for the condensors is so high and that they often lose vacuum and
have to shut down. This still doesn't serve as much of an indicator for
what sea water temps might have been at the locale and at the time of the
purported aquatic phase of human evolution.
Elisabeth Vrba has confirmed a period of world-wide cooling from 7 to
four-and-a-half million years ago, and believes that sea water
temperatures had dropped 5 to ten degrees F at the end of that period.
Unfortunately, that doesn't give us an absolute figure because we don't
have a figure with which to begin. (Help us out, you geochemists and
paleo-oceanographers??)
On the other hand, it might not be that critical. Some human beings have
demonstrated tolerance for water and air temperatures over an amazingly
wide range. See the DARWIN READER, pages 40-41 desribing naked Fuegians
sleeping on the ground in temps as low as 38F, suckling newborns in the
sleet, diving in the icy waters of the South Atlantic,etc.
Some of you might also want to check this reference for the Fuegians
dietary habits. You guessed it, lots of shellfish.
