On June 28th, 2023, the Canadian Coast Guard welcomed the Horizon Arctic, a ship carrying a remotely operated vehicle (ROV) that had been searching for the Titan submersible near the wreck of the Titanic. The ROV had discovered debris from the sub about 1,600 feet from the bow of the Titanic at the bottom of the Atlantic, consistent with a catastrophic implosion of the vessel. The Canadian Coast Guard is continuing to investigate the cause of the implosion and the fate of the five people on board the Titan submersible.
