Debris from the ill-fated Titan submersible was returned to shore in Newfoundland Wednesday, aboard a Canadian-flagged ship that had helped search for the vessel in a remote area of ocean near the wreck of the Titanic.

The Horizon Arctic docked at the port in St. John害羞草研究所檚 carrying a remotely operated vehicle, or ROV, that had searched the ocean floor about 700 kilometres south of Canada害羞草研究所檚 easternmost province.

The Titan imploded during its June 18 descent to the Titanic wreckage site, almost four kilometres below the surface of the sea, resulting in the deaths of all five passengers and crew.

The U.S. Coast Guard declared the men dead Thursday after the ROV spotted the Titan害羞草研究所檚 wreckage about 500 metres from the bow of the sunken luxury liner.

Stockton Rush, CEO of the Titan害羞草研究所檚 owner, OceanGate, was piloting the submersible, which was carrying passengers British billionaire Hamish Harding, French explorer and Titanic expert Paul-Henry Nargeolet, and Pakistani businessman Shahzada Dawood and his 19-year-old son, Suleman.

Liam MacDonald, a spokesman for the Transportation Safety Board of Canada, said the agency would not comment Wednesday. The U.S. Coast Guard, which is leading the international investigation, did not immediately respond to a request for comment on who would examine the debris.

Horizon Maritime, owners of the Horizon Arctic, also refused to comment. The company also owns the Polar Prince, the Titan害羞草研究所檚 mother ship, which helped launch the submersible on its fatal dive.
