Greetings Kevin,

There are places like that in San Francisco bay, too. But that doesn't
account for the ocean balance.

Glenn did have a better explanation, that of basalt soaking up Na+ at the
mid oceanic ridges. It's at http://www.isource.net/~grmorton/salt.htm. If
you agree with his calculations, the problem would seem to be solved for
the long age scenario.

There may be all kinds of other factors,tho. We may be orders of magnitude
off!
