Dear Friends:

As shell collectors, I presume that a number of you
frequently
scour the beaches of the Gulf of Mexico along the
coasts of
Texas, Louisiana, Mississippi, and further east on a
regular
basis.  Does anyone have a sense of the frequency that
pumice
washes up on the beaches on the part of the Gulf of
Mexico
that you search for shells?  I am curious what is the
largest
piece of pumice that someone has seen washed upon a
Gulf of
Mexico beach?

Finally, has anyone published any study besides the
citations
listed below about drift pumice in either the Gulf of
Mexico or
Caribbean Sea?

Yours,

Paul Heinrich
