The last I heard, Dr. Judith Bense was the chairman of the Florida Historical Commission. If you're looking for getting permitted for exploration of a discovered wreck, you pretty much want to avoid her like the plague. In many of my posts, she is the one that I refer to when I say that state archies would rather it disentegrate than let a novice recover an item.
I think Dr. Roger Smith is still the leading Marine Archaeologist for the State of Florida, but again I could be wrong.
