Many different systems.

SOSUS Sound Surveillance System

IUSS Integrated Undersea Surveillance System

Both are sited on the seabed.

Probably other sonar, hydrophone, or other tracking systems all over the Atlantic to track submarines all integrated with aircraft maritime submarine radar, sonar systems.

Hard to believe that the military don't have them wired for sound.

Who knows what modern systems have supplemented the older systems I mentioned.

With the dive mothership on the surface above the wreck monitoring the dive they should know the location with a relatively small margin of error.
