Pleasure is always on.

Magnum, true to pleasure.

CBS, I'm John Batch with Anthony Elcuri, Charles Pelagrino, two of the three authors James Cameron

as the third on a new piece of scientific analysis of the Titanic at the bottom of the sea.

This is about what is called rusticles and in a particular part of the Titanic, the Turkish bass.

I welcome Anthony to help us understand what was known before of rusticles and what is new here.

Anthony, there's a great deal of what I'd say was extremely sophisticated chemistry going on here.

Can you help me understand what I'm supposed to be reading? Good evening to you.

Yes, good evening.

So regarding the rusticles, it's really more of a field of biogeochemistry.

So the rusticles are these microbes that are really, really, they're accused of consuming the wreck,

but really they're more involved with metabolizing and respiring the iron in the ship.

And the progress of this is what you're identifying in the abstract.

But when we get into the body of the work, we're talking about science has not been done before.

Or is this something we've done on land?

Well, we've evaluated the rusticles before. We've seen that they're largely sulfate and iron metabolizing organisms that are consuming the iron in the wreck, metabolizing it.

But really, within deep within the wreck, exploration has yielded unique rusticle formations.

Really rusticle formations that are unique to a chamber in the wreck called the Turkish bass.

And this was a former aerobics spa aboard the Titanic, kind of aerobics seemed more as styles carved woodwork reminiscent of the Middle East.

And within the wreck, James Cameron in July of 2005 discovered that the rusticle bacteria within the marine sediment was blooming up out of the marine sediment.
