I found this article about the challenges of deep diving for a wreck in 240' of water in the Persian Gulf interesting, Deep Diving is below about 140'. The living quarters for saturation divers is so small it is like living in a coffin underwater for days, or weeks, at a time.

It makes a submarine seem like spacious living quaters

I was wondering if the excavation of the Mary Rose might provide a precedent, but it seems that wasn't at even half the depth of this.

Now this would not be so bad. Only 80' of water, and warm water at that!

What about sharks?

Well, the Great White does sometimes visit the med, but not real commom there.

The ones I really hate, from personal exprience, are the Bulls Sharks, which go by many names in different parts of the world, but they are also uncommon in the Med

but not real commom there.

It only takes one.
