Very neat.
I got hooked the other night on a show called.. Treasure Hunter (I think). It was about a ship called the Odyssey, and they were finding old ship wrecks. They two episodes I watched were about the HMS Victory in the English Channel (2009).
It was pretty amazing the technology and everything. But at 1 am, I had to give up and go to bed. :-)
There’s a current Bloomberg article (can’t use it on FR, copyright complaint) about new dives on the Mentor, which went down in 1802 carrying the so-called Elgin Marbles. All the stones were recovered shortly after the ship sank, but various people keep looking for more.
