Marine safety engineers with the Coast Guard’s Marine Board of Investigation recovered and transferred remaining Titan submersible debris and evidence from the North Atlantic Ocean seafloor Wednesday.

The salvage mission, which was conducted under an existing agreement with U.S. Navy Supervisor of Salvage & Diving, was a follow-up to initial recovery operations following the loss of the Titan submersible. Investigators from the U.S. National Transportation Safety Board and the Transportation Safety Board of Canada joined the salvage expedition as part of their respective safety investigations.

The recovered evidence was successfully transferred to a U.S. port for cataloging and analysis. Additional presumed human remains were carefully recovered from within Titan’s debris and transported for analysis by U.S. medical professionals.

The MBI is coordinating with NTSB and other international investigative agencies to schedule a joint evidence review of recovered Titan debris. This review session will help determine the next steps for necessary forensic testing.

The MBI will continue evidence analysis and witness interviews ahead of a public hearing regarding this tragedy.
