The region of were the wreck likely is unless its nearer to the coast, so Im not speculating were it is, becuase I dont have a clue. However the water pressure at the bottom of the Atlantic is very heavy, something like several tons per inch, about 31 bar, 465 psi, 3100 kPa per 1000ft, looking at the figures thats roughtly would put that plane 2.5 miles down, so surviving it is remotely Impossible, The only things to implode on a person are the lungs and air cavities, and the inner ears. Not the bodies itself, so if you can get a sub down there its recoverable but then with a storm nearby the surface of the water will be mirky, so its likely going to be a few days, maybe weeks.
If looking at that map, its near enought if the wreck has sunk its about the depth of the titanic so were talking about only seven submersibles in the world can go to such depths.
