On Wednesday, pieces of the sub, which collapsed on a deep dive to the Titanic, were unloaded at St John’s, Canada.
The landing frame and a rear cover of the submarine were discovered among the rubble, according to officials.
The coast guard said in a statement that US medical personnel will conduct a formal analysis of supposed remains.
The agency is in the early stages of investigating the disaster’s causes. The evidence will be transported to a US port by the Coast Guard’s Marine Board of Investigation (MBI) for further analysis and testing.
According to MBI chair Capt Jason Neubauer, “there is still a substantial amount of work to be done to understand the factors that led to the Titan’s catastrophic loss and help ensure a similar tragedy does not occur again.”
“I am grateful for the coordinated international and interagency support to recover and preserve this vital evidence at extreme offshore distances and depths,” stated Captain Neubauer.
What will Titan’s investigators be on the lookout for?
Among the subvictims are a British father, son, and adventurer.

On June 18, all five people on board died when the ship exploded approximately 90 minutes into a dive to see the famed 1912 shipwreck, which is located at a depth of 3,800m (12,500ft) in the north Atlantic.
The passengers included 61-year-old Stockton Rush, the head of OceanGate, which organized the dive; British adventurer Hamish Harding, 58; Shahzada Dawood, 48, and his son, Suleman Dawood, 19; and French diver Paul-Henry Nargeolet, 77.
Officials were originally skeptical that any of the bodies could be recovered.
“This is an incredibly unforgiving environment down there on the seafloor,” Coast Guard Adm John Mauger said after the vessel’s loss was confirmed.
Cpt Neubauer stated at the time that if human remains were recovered, investigators would take “all precautions” and that the investigation would most likely entail a formal hearing with witness testimony.
According to the coast guard, five main parts of the submarine have been discovered in a massive debris field near the Titanic’s bow.
According to BBC science journalist Jonathan Amos, the debris hauled ashore on Wednesday looked to include at least one titanium end cap, the sub’s porthole with its window missing, as well as a titanium ring, landing frame, and the end equipment bay.
The Canadian ship Horizon Arctic spearheaded the rescue mission, which included a remotely operated vehicle operated by Pelagic Research Services. In a statement issued earlier Wednesday, the business stated that its team had concluded off-shore activities and was returning to base.
Former employees have expressed worries about the Titan sub, which was not subject to regulation, and OceanGate has been chastised for its safety measures.
Mr Rush previously dismissed safety concerns raised by one expert, saying he was “tired of industry players who try to use a safety argument to stop innovation” in email messages obtained by the BBC.
Another former OceanGate employee also prepared an inspection report that indicated “numerous issues that posed serious safety concerns,” such as how the hull was evaluated.
OceanGate said in a statement last week that it was “an extremely sad time for our employees who are exhausted and grieving deeply over this loss.”
