Thanks, Dan.

Interesting.  This would support the contention that the concentration
in seawater is due to evaporation, and that while the ocean is very big,
it has been at it for a very, very long time.

Dear Doug:

I think that you are correct. The concentration in seawater may very
well be
uniformly greater than the input due in large part to evaporation.
