The US coastguard has recovered the remaining debris from the Titan sub.
Officials said the salvage mission conducted under an agreement with the US Navy was a follow-up to initial recovery operations on the ocean floor.
It comes almost four months after the five passengers on board the sub were killed as it tried to reach the wreck of the Titanic.
When it imploded, it was said to be roughly 1,600 feet (488 meters) away from the vessel.
The coastguard said today that the recovery and transfer of remaining parts was completed last Wednesday.
Investigators believe the Titan imploded as it made its descent into deep North Atlantic waters on June 18.

The multi-day search mounted after Titan went silent captured attention around the world.
The submersible was attempting to view the passenger liner that sank in 1912.
The coastguard previously said it recovered presumed human remains along with parts of the Titan after the debris field was located at a depth of 12,500 feet (3,800 metres).
The materials were offloaded at an unnamed port. The Coastguard’s Marine Board of Investigation is continuing its analysis and conducting witness interviews ahead of a public hearing on the tragedy.
OceanGate, the operator of the vessel, has since gone out of business. Among those killed in the implosion was Stockton Rush, the submersible’s pilot and chief executive of the company.
A US coastguard spokesperson said: ‘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 (NTSB) 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.’
