Titanic Sub Search Expands to Ocean Floor, ‘Debris Field’ Discovered

The desperate search for a missing submersible near the wreck of the Titanic entered a critical juncture on Thursday when air was expected to run out for the five people aboard, but officials vowed to continue scouring the remote North Atlantic.

A remotely operated vehicle deployed from a Canadian vessel to the ocean floor discovered a "debris field" near the Titanic, the US Coast Guard said on Thursday morning on Twitter, adding that experts were "evaluating the information."

Another robot from a French research ship was also sent diving toward the seabed to search for signs of the 22-foot (6.7-meter) Titan submersible.

The van-sized Titan, operated by US-based OceanGate Expeditions, began what was to be a two-hour descent at 8 a.m. (1200 GMT) on Sunday but lost contact with its support ship.

The submersible set off with 96 hours of air, according to the company, which means the oxygen would be exhausted by Thursday morning, assuming the Titan is still intact. Precisely when depends on factors such as whether the craft still has power and how calm those on board are, experts say.

Rescuers and relatives of the Titan's five occupants took hope when the US Coast Guard said on Wednesday that Canadian search planes had recorded undersea noises using sonar buoys earlier that day and on Tuesday.

But remote-controlled underwater vehicles searching where the noises were detected did not yield results, and officials cautioned the sounds might not have originated from the Titan.

US Coast Guard rear admiral John Mauger told broadcaster NBC earlier on Thursday that the search would continue throughout the day.

Deep-sea adventure

The Titanic, which sank in 1912 on its maiden voyage after hitting an iceberg, killing more than 1,500 people, lies about 900 miles (1,450 km) east of Cape Cod, Massachusetts, and 400 miles (640 km) south of St. John's, Newfoundland.

The Titan's deep-sea excursion to the shipwreck capped a tourist adventure for which OceanGate charges $250,000 per person.

The passengers included British billionaire and adventurer Hamish Harding, 58, and Pakistani-born business magnate Shahzada Dawood, 48, with his 19-year-old son Suleman, who are both British citizens.

French oceanographer and leading Titanic expert Paul-Henri Nargeolet, 77, and Stockton Rush, the US founder and chief executive of OceanGate, were also on board. Rush is married to a descendant of two of the Titanic victims.

"We're waiting anxiously, we hardly sleep," said Mathieu Johann, Nargeolet's editor at his publisher Harper Collins.

Sean Leet, who heads a company that jointly owns the support ship, the Polar Prince, has said all protocols were followed before the submersible lost contact.

"There's still life support available on the submersible, and we'll continue to hold out hope until the very end," said Leet, chief executive of Miawpukek Horizon Maritime Services.

Questions about Titan's safety were raised in 2018 during a symposium of submersible industry experts and in a lawsuit filed by OceanGate's former head of marine operations, which was settled later that year.

Even if the Titan were located, retrieving it would present huge logistical challenges.

If the submersible had managed to return to the surface, spotting it would be difficult in the open sea and it is bolted shut from the outside, so those inside cannot exit without help.

If Titan is on the ocean floor, a rescue would have to contend with the immense pressures and total darkness at that depth. British Titanic expert Tim Maltin said it would be "almost impossible to effect a sub-to-sub rescue" on the seabed.

It may also be difficult to find the Titan amid the wreck.

"If you've seen the Titanic debris field, there'll be a thousand different objects that size," said Jamie Pringle, a forensic geoscientist at Keele University in the United Kingdom. "It might be an endless task."

A giant balloon that became a popular landmark over the skies of Paris during the 2024 Olympics is set to rise again, with organizers hoping it will once again attract crowds of tourists.

During the Games, the Olympic cauldron tethered to a balloon flew above the Tuileries garden at sunset every day, with thousands flocking to see the seven-meter (23 feet) wide ring of electric fire, AFP said.

Last summer's version "had been thought up to last for the length of the Olympic and Paralympic Games," said Mathieu Lehanneur, the designer of the cauldron.

After President Emmanuel Macron "decided to bring it back, all of the technical aspects needed to be reviewed", he told AFP on Thursday.

Lehanneur said he was "very moved" that the Olympic balloon was making a comeback.

"The worst thing would have been for this memory to become a sitting relic that couldn't fly anymore," he said.

The new cauldron will take to the skies on Saturday evening during France's annual street music festival, the Fete de la Musique.

The balloon will rise into the air every evening until September 14 -- a summer tradition set to return every year until the 2028 Los Angeles Games.

"For its revival, we needed to make sure it changed as little as possible and that everything that did change was not visible," said Lehanneur.

With a decarbonated fire patented by French energy giant EDF, the upgraded balloon follows "the same technical principles" as its previous version, said director of innovation at EDF Julien Villeret.

The improved attraction "will last ten times longer" and be able to function for "300 days instead of 30", according to Villeret.

The creators of the balloon also reinforced the light-and-mist system that "makes the flames dance", he said.

Under the cauldron, a machine room hides cables, a compressor and a hydro-electric winch.

That system will "hold back the helium balloon when it rises and pull it down during descent", said Jerome Giacomoni, president of the Aerophile group that constructed the balloon.

"Filled with 6,200 m3 of helium that is lighter than air," the Olympic balloon "will be able to lift around three tons" of cauldron, cables and attached parts, he said.

The Tuileries garden is where French inventor Jacques Charles took flight in his first gas balloon on December 1, 1783, Giacomoni added.

He followed in the footsteps of the famed Montgolfier brothers, who had just nine days earlier elsewhere in Paris managed to launch a similar balloon into the sky with humans onboard.
