Given the high price of copper I would guess that they pull the copper cables out after service. I am not so sure about fiber cables.

  Given the cost of such an operation, I don't think you can get some profit even if they were made of gold. As time passes, most of the cable is buried deeper and deeper under debris that falls on the ocean floor. This means that you cannot just pull it up, you would have to dig to get it out.

    Most cables don't run on the seabed.

      Umm, then where do they run? They can't float in the middle of the water.

        Uh, yeah they do. Often they hang from a buoy, floating in the middle of the water.

    Go a few miles out and there is very little to debris to fall onto the ocean floor.
