Five people died while on board the deep-sea vessel which was visiting the Titanic wreck.
An American military official now suggests an existing system of navy sonars heard a noise consistent with an implosion.
Rear Admiral John Mauger, who led the US Coast Guard's search, suggested it would have been loud enough:
"This was a catastrophic implosion in the vessel, which would have generated a significant broadband sound down there that sonar buoys would have picked up."
