Coast Guard Marine Board of Investigation releases audio recording

A National Oceanic and Atmospheric Administration (NOAA) moored passive acoustic recorder, approximately 900 miles from the Titan submersible implosion site, records the suspected acoustic signature of the Titan submersible implosion, June 18, 2023. The U.S. Coast Guard’s Titan Marine Board of Investigation (MBI) released the audio as part of the investigation and as an investigation exhibit. The recording was provided to the MBI by NOAA, which approved its use in the investigation and public release.
