The Coast Guard said in a statement that the audio clip “records the suspected acoustic signature of the Titan submersible implosion” on June 18, 2023, the day the submersible went missing.
A National Oceanic and Atmospheric Administration passive acoustic recorder located about 900 miles (1,448 kilometers) away from the implosion site picked up the sound, U.S. Coast Guard officials said in a statement.
The implosion of the Titan killed all five people on board and set off a Coast Guard investigation and international debate about the future of private deep-sea travel.
A recording released by the federal government appears to include audio of the implosion of the experimental submersible that went missing on its way to the wreck of the Titanic.
The implosion also killed two members of a prominent Pakistani family, Shahzada Dawood and his son Suleman Dawood; British adventurer Hamish Harding; and Titanic expert Paul-Henri Nargeolet.
