Jim, if there's no O2 dissolved in deep sea water, how do deep sea fish
breathe?
The problem with the deep, open ocean is there's no FOOD at depth, since
the source of energy is the SUN. So creatures tend to be scarce. But
there's still Oxygen. It pretty well diffuses through the entire ocean.
Part of the reason the Titanic and other ships are still there is due to
the tremendous thickness of the metal used to construct them. That and
the lack of circulation on the ocean floor, which tends to keep the
surface oxydates and other salts in place. This protects the underlying
metal to a large degree. Oh, and the cold slows down the reaction as well.

After all, the USS Arizona is sitting in only a few dozen feet of water,
where there's plenty of O2, and it hasn't corroded away in the 50-some
years it has been sitting there. Indeed, it is still leaking oils to this
day.
