ABCnews is carrying this summary of a recent TV broadcast concerning Robert Ballard's return to Titanic, this time to document deterioration and (in some opinion's) desecration. If I recall correctly (IIRC), the last studies done suggested the forward section would probably collapse outright from corrosion in the next twenty years or so. What's not clear is if the various expiditions are contributing to this problem.
Kinda conflicted about this one. Yes, it's a grave site, but because of the natural processes of sea life, it's an empty one. And, contrary to Ballard's assertion in the article, people do get married in graveyards. Odd people, and not very many, but it happens.
The cold truth is that as long as there's profit to be made on the wreck, there will be people picking on it.
