A very interesting article. That said I state the fact that I have been a team member and dove and excavated Spanish Colonial period shipwrecks in the Florida Keys, Bahamas, Central Caribbean and extensively off the coasts of the Dominican Republic. In excavations reaching as deep as 12 feet into the sub-bottom I have observed portions of still remaining timbers that showed evidence of white in color calcarious like secretions coating some of the timbers, but NEVER was there solidified teredo worm crap blanketing the remnants of the shipwreck.
Another absurd flimsy excuse for SFRX total failures that go on and on endlessly.
