Debris found in Titan submarine search area

The US Coast Guard has discovered multiple pieces of debris in the search area for the missing Titan submarine, where oxygen may have run out.

"A rover (ROV) detected a cluster of debris on the seabed in the search area near the wreck of the Titanic. Experts at the search command center are evaluating information from this debris," the US Coast Guard said on the afternoon of June 22 (June 22 evening, Hanoi time).

The Titan submersible went missing on June 18 while carrying five people on a tour of the Titanic wreck at the bottom of the Atlantic Ocean, at a depth of nearly 4,000 meters, about 600 kilometers from Newfoundland, Canada. The US Coast Guard estimated that the Titan had enough oxygen for five people for 96 hours since it went missing.

With this estimate, the five people on the Titan submersible ran out of oxygen at around 7:10 a.m. on June 22 (around 6:10 p.m. Hanoi time). Oxygen could have run out sooner if the passengers panicked and breathed heavily, but it would have lasted longer if they knew how to conserve oxygen in a confined space, according to experts.

Guillermo Sohnlein, co-founder of OceanGate with Stockton Rush, one of the five people on the missing submersible, expressed confidence that the crew had enough experience to hold out until rescue. He said today was a "critical day in the search and rescue mission."

"I continue to hold out hope for my friend and the rest of the crew," Sohnlein said. "I encourage everyone to continue to hope that they will return safely."

The search area has been expanded to twice the size of Connecticut, the US state with a territory of more than 13,000 square kilometers. Victor 6000, a deep-sea diving robot equipped with the French research vessel Atalante, has approached the wreck of the Titanic to join the search effort for the Titan submersible. The robot is capable of diving to a depth of 6,000 meters.

A Canadian P-8 Poseidon surveillance aircraft had previously recorded loud noises near the location of the missing Titan submersible every 30 minutes. Four hours later, they dropped more sonobuoys and still heard the sound.

It is not yet clear where the noise originated, but French expert Paul-Henri Nargeolet said it could be a "human sound", if it did come from the submersible.
