What's known so far about the search for the missing Titanic submersible

The submersible last headed for the Titanic off the coast of Newfoundland is still missing as of Tuesday morning.

The U.S. Coast Guard is leading the operation with assistance from the Canadian Coast Guard vessel Kopit Hopson 1752 and air search from the Royal Canadian Air Force Aurora aircraft out of 14 Wing Greenwood.

The passenger submersible operated by OceanGate left St. John's, N.L. on Sunday morning and then lost contact with surface crews one hour and 45 minutes into the expedition.

Time is of the essence in the search due to the 96-hour oxygen supply aboard the vessel.

Here's what we know so far about the missing submersible:

WHO IS ON BOARD?

The submersible is carrying five passengers, including Hamish Harding, a billionaire and explorer, Paul-Henry (PH) Nargeolet, a French explorer, Shahzada Dawood and his son Suleman, members of one of Pakistan's prominent families and, according to Reuters, OceanGate CEO Stockton Rush.

"We started steaming from St. Johns, Newfoundland, Canada yesterday and are planning to start dive operations around 4am tomorrow morning," Harding wrote on Facebook on Saturday. "The team on the sub has a couple of legendary explorers, some of which have done over 30 dives to the RMS Titanic since the 1980s including PH Nargeolet."

WHAT THE SEARCH LOOKS LIKE

Former U.S. Coast Guard captain Andrew Norris told CTV's Your Morning on Tuesday "time really is the enemy."

"The challenge is finding it… that's going to be difficult enough, but then affecting some sort of rescue," he said. "That indicates the challenge that rescuers will face to do some sort of recovery, even if they do find it."

Search and rescue teams are battling the clock as the oxygen onboard the submersible lasts about 96 hours. Norris indicated there could be emergency oxygen supplies on board as well.

"They would have the normal oxygen supply that we're talking about that is a 96-hour window, but they'd also have — like on a plane if there was a fire or something — they'd have the ability to put on some sort of oxygen breathing device," Norris said.

The U.S. Coast Guard said at a press conference Monday that sonar technology is playing a key role in the search efforts.

If the vessel is found, Norris says, the rescue would be in "very difficult circumstances."

"The Sea State has to allow the deployment of that equipment, they have to and then it has to work kind of perfectly the first time so it's really a challenge," he said.

Beth Penney, a reporter with CTV News affiliate NTV in Newfoundland, told CTV's Your Morning on Tuesday that weather conditions have not been good for search efforts.

"We learned through social media, that this was going to be the only expedition that OceanGate was going to take to the Titanic wreckage this year, and that's because of poor weather conditions in Newfoundland and Labrador," Penney said.

CANADA'S ROLE IN THE SEARCH

The area where the submersible went missing is under U.S. jurisdiction, Minister of Fisheries, Oceans and the Canadian Coast Guard, Joyce Murray, told CTV News.

"There is a unified command under the U.S. Coast Guard’s leadership that Canada is playing a very committed role in," she said. "The Canadian Coast Guard is doing everything that we can to help. We have the CCGS John Cabot (that) has sonar and it is headed to the site."

Both the U.S. and Canadian coast guards have teams looking for the submersible and the Royal Canadian Air Force has an aircraft flying above.

"Maritime Rescue Coordination Centre (MRCC) Boston has requested assistance from Joint Rescue Coordination Centre (JRCC) Halifax in the search of an overdue submarine," a spokesperson from the RCAF told CTVNews.ca in an email. "The submersible has lost communications with its surface vessel located 380NM south of St. John’s N.L."

Kathryn Hallett, a spokesperson from Fisheries and Oceans Canada told CTVNews.ca in an email, "Joint Rescue Coordination Centre (JRCC) Halifax is providing assistance as required."

Murray says two other Canadian Coast Guard ships are in St. John's ready to port equipment.

When asked if any Canadian facilities came in contact with the submersible Murray initially said she would not "go into details."

"Because this is a hugely emotional issue for those who are doing this work to save the people aboard the submersible and their families, and every effort is being made," she said. "It's an international initiative at this point with assets coming from Great Britain and Germany."

However, Murray confirmed that Canadian facilities are doing "everything in their power" to assist in the search. 

WHY IT COULD HAVE LOST CONTACT

Norris says there are multiple ways for a submersible to lose contact with the surface crew.

"There could have been a catastrophic breach, which would have resulted in an implosion, it could have had some sort of fault that caused it to lose communications and or the ability to lift itself off the seabed," Norris speculated.

Other potential issues include getting caught in debris that can be found along the ocean floor and near the Titanic.

Officials have not confirmed why the submersible lost contact.

WHERE WERE THEY GOING?

OceanGate Inc. is a privately owned U.S.-based company that provides tourism explorations to the deep ocean.

The company's website says the five-person submersible, named Titan, can reach depths of up to 4,000 metres — 7.2 times as tall as the CN Tower.

The Titanic, which sank in 1912, is located about 600 kilometres southeast of Newfoundland in the North Atlantic Ocean. OceanGate expeditions to the wreck cost passengers about C$300,000.

The submersible is made of carbon fibre and titanium and is 6.7 metres long.

I just watched a 60 minutes interview with James Cameron about this and there’s a clip of Stockton piloting his toy sub with visible condensation inside the window. He’s in his socks with a game controller going around in circles in the dark at depths unimaginably deep. He had no idea what literal pressure he was under and that literal pressure literally killed him.

I have a theory that the expert who Stockton hired, Paul-Henri Nargeolet, knew exactly how bad it was. PH had a personal death wish after the death of his wife and wanted to rest his body at the wreckage site because…well. people who get obsessive over titanic probably get it. It’s so incredibly dark down at the bottom of the sea floor and if you don’t know where you are going and what direction the ocean currents are you can easily get caught in the iron cables that held the smokestacks to the deck. It’s insanely dangerous for so many factors other than there’s a lot of water. Basically the entire thing was a shit show from the start and the only reason it continued and concluded the way it did is because of money.

Capitalism. Full stop.

i read the recent wired article about the ocean gate titanic sub and i think the most understatedly eyebrow raising aspect of that whole debacle honestly is that the ceo seems to have been personally manning half their unsafe deep sea dives... like usually in a story like this it turns out the people at the top were brushing off safety concerns because they knew they personally could avoid consequences and were willing to risk their employees and customers. and im sure there were some people at ocean gate doing that. but stockton rush was as far as i can tell genuinely convinced of his own genius corner cutting engineering hacks to the point where he kept manning these vessels even after tests where they were failing and warnings from university labs and boeing engineers and hearing the hull make ominous creaking sounds while he himself was piloting it like... man with zero survival instincts to a point seldom seen in wealthy startup assholes who absolutely have the financial wherewithal to save their own necks

Titanic Mission To Map Wreck In Greatest-Ever Detail

— By Jonathan Amos & Alison Francis | 12 July 2024

Six-tonne robots will spend up to 20 days mapping and cataloguing the wreck site

A team of imaging experts, scientists and historians set sail for the Titanic on Friday to gather the most detailed photographic record ever made of the wreck.

The BBC had exclusive access to expedition members in the US city of Providence, Rhode Island, as they made preparations to leave port.

They'll be using state of the art technology to scan every nook and cranny of the famous liner to gain new insights into its sinking.

This is the first commercial mission to Titanic since last year's OceanGate tragedy. Five men died while trying to visit the lost ship in a novel submersible.

A joint memorial service will be held at sea in the coming days for them and the 1,500 passengers and crew who went down with Titanic in 1912.

The new expedition is being mounted by the US company that has sole salvage rights and which to date has brought up some 5,500 objects from the wreck.

But this latest visit is purely a reconnaissance mission, says RMS Titanic Inc, based in Atlanta, Georgia.

Two robotic vehicles will dive to the ocean bottom to capture millions of high-resolution photographs and to make a 3D model of all the debris.

"We want to see the wreck with a clarity and precision that's never before been achieved," explained co-expedition lead David Gallo.

Titanic was the largest and most luxurious passenger ship of its day

The logistics ship Dino Chouest is going to be the base for operations out in the North Atlantic.

Weather permitting, it should spend 20 days above the wreck, which lies in 3,800m (12,500ft) of water.

It will be a poignant few weeks for all involved.

One of the five who died on the OceanGate sub was Frenchman Paul-Henri ("PH") Nargeolet. He was the director of research at RMS Titanic Inc and was due to lead this expedition.

A plaque will be laid on the seabed in his honour.

"It's tough but the thing about exploration is that there's an urge and a drive to keep going. And we're doing that because of that passion PH had for continuous exploration," explained friend and historian Rory Golden, who will be "chief morale officer" on Dino Chouest.

On its last visit in 2010, RMS Titanic Inc made a sonar map of the wreck site

There can be few people on Earth who don't know the story of the supposedly unsinkable Titanic and how it was holed by an iceberg, east of Canada, on the night of 15 April 1912.

There are countless books, movies and documentaries about the event.

But although the wreck site has been the target of repeated study since its discovery in 1985, there still isn't what could be described as a definitive map.

And while the bow and stern sections of the broken ship are reasonably well understood, there are extensive areas of the surrounding debris field that have received only cursory inspection.

There is still much to learn about Titanic, even its famous bow

Two six-tonne remotely operated vehicles (ROVs) intend to put that right. One will be fitted with an array of ultra-high-definition optical cameras and a special lighting system; the other will carry a sensor package that includes a lidar (laser) scanner.

Together, they'll track back and forth across a 1.3km-by-0.97km section of seafloor.

Evan Kovacs, who's in charge of the imaging programme, says his camera systems should produce millimetre resolution.

"If all of the weather gods, the computer gods, the ROV gods, the camera gods - if all those gods align, we should be able to capture Titanic and the wreck site in as close to digital perfection as you can get. You would be able to quite literally count grains of sand," he told BBC News.

Powerful cameras should return unprecedented detail from the deep

There's huge anticipation for what the magnetometer aboard the sensor ROV might produce. This is a first for Titanic.

The instrument will detect all the metals at the wreck site, even material that is buried out of sight in the sediment.

The sensor instruments, including the magnetometer, will return fascinating new data

"It would be an absolute dream to determine what has happened with Titanic's bow below the seafloor," explained geophysics engineer Alison Proctor.

"Hopefully, we'll be able to deduce whether or not the bow was crushed when it hit the seabed, or if it might actually extend down well into the sediment intact."

The team wants to review the state of some well known objects in the debris field, such as the boilers that spilled out as the opulent steamliner broke in half.

A rendering of what the electric candelabra might have looked like

There's the desire, too, to locate items thought to have been sighted on previous visits. These include an electric candelabra, which in its day would have been a fascinating curio, as well as the possibility of a second Steinway grand piano.

The musical instrument's wooden surround would have long since decayed away, but the cast iron plate, or frame, that held the strings should still be there, and perhaps even some of the keys.

"For me, it's the passengers' possessions, especially their bags, that are of greatest interest," said Tomasina Ray, who curates the collection of Titanic artefacts held by the company.

"It's their belongings - if we are able to retrieve more in the future - that help flesh out their stories. For so many passengers, they are just names on a list, and it's a way to keep them meaningful."

Rory Golden says the memorial plaque for PH will be placed upright in the sediment

This will be RMS Titanic Inc's ninth visit to the wreck site. The firm has attracted controversy in recent years with its stated desire to try to bring up part of the Marconi radio equipment that transmitted the distress calls on the night of the sinking.

It won't happen on this expedition but if and when it does occur, it would mean extracting an object from inside the disintegrating ship.

For many, Titanic is the gravesite to the 1,500 who died that night in 1912 and should not be touched, its interior especially.

"We get that and understand it," said company researcher James Penca.

"We dive to Titanic to learn as much as we can from her; and like you should with any archaeological site, we do it with the utmost respect. But to leave her alone, to just let her passengers and crew be lost to history - that would be the biggest tragedy of all."

It is the personal items, some preserved inside bags, that tell the stories of the dead

An inside look at the first solo trip to the deepest point of the Atlantic

New Post has been published on https://nexcraft.co/an-inside-look-at-the-first-solo-trip-to-the-deepest-point-of-the-atlantic/

An inside look at the first solo trip to the deepest point of the Atlantic

One down!” Those were Victor Vescovo’s first words after climbing out of the hatch of the DSV Limiting Factor. He had just dove 27,480 feet down to the bottom of the Puerto Rico Trench, making him the first person to reach the absolute nadir of the Atlantic Ocean. Or at least those were the first intelligible words, over the waves, and the motor of the nearby Zodiac raft, and the low hum of the support vessel DSSV Pressure Drop, which was idling nearby.

The sun had just set, creating a ridiculous backdrop of orange sky and translucent blue Caribbean water. It would have seemed stage-directed, had I not been on the Pressure Drop for a week by then, observing three failed tests that put the whole dive in jeopardy. The Pressure Drop needed to leave its post at 7 p.m. on Wednesday, December 19 in order to reach its port call in the Dominican Republic the next morning. Vescovo surfaced from his six-hour, 55,000-foot round-trip journey to the ocean floor and back at approximately 5:45 p.m.—just over an hour to spare. Next year, provided there are no major setbacks, he plans to take the Limiting Factor around the planet in an attempt to become the first person to reach the lowest point in all five oceans. Hence those first words: one down, four to go.

The dive also made Vescovo the second deepest-diving solo sub pilot in history, after the film director James Cameron, who reached the bottom of the Pacific’s deepest point, the Mariana Trench, in 2012. Vescovo will head there, too, probably in the summer of 2019, after attempting the 8,180-meter (26,847-foot) South Sandwich trench near Antarctica, and the 7,290-meter (23,917-foot) Java Trench, with a likely stop to visit and film the wreck of the USS Indianapolis en route.

This audacious, self-funded mission is known as the Five Deeps. It is more than three years in the making and began when Vescovo asked Triton Subs, a small, Florida-based maker of submersibles, if they could build him a vehicle capable of reaching any point in the world’s oceans.

This was a big ask. Three years ago, there was no vehicle on Earth capable of such a feat—or anything close to it. Cameron’s sub, the DSV Deepsea Challenger, caught fire after a freak highway accident a few years after his expedition and was never repaired. And there are only five working submersibles capable of going past the oceans’ average depth of 4,000 meters (13.123 feet). All five of those are owned and operated by national governments, and unavailable for private use. But Triton co-founder Patrick Lahey had been chewing over the idea of a full-ocean-depth sub for years; he just needed someone to pay for it. (The sub cost $35 million. With the Pressure Drop the price tag is more than $45 million.) That arrangement worked for Vescovo, a Dallas-based private equity investor with a thirst for adventure. He’s one of just 12 Americans to have climbed the Seven Summits and skied to both poles—the so-called Grand Slam of adventuring.

So when Vescovo passed 7,100 meters (23,200 feet) sometime early Wednesday afternoon, the Limiting Factor surpassed China’s Jiaolong (which reached 7,020 meters in 2012) to become the world’s deepest-diving submersible. And if Vescovo’s successful in reaching Challenger Deep in the Mariana Trench next year, it will be the only sub officially rated to full ocean depth—built to repeatedly reach the sea’s deepest places.

Almost no one thought it was a good idea for Vescovo to attempt the Puerto Rico Trench dive solo. Lahey tried very hard to convince him that he needed a co-pilot—someone with submersible diving experience—but that was a non-starter. Vescovo is a jet-rated pilot who’s been flying planes since age 18. He had Triton install a simulator in his garage so that he could practice while the sub was being assembled in Florida. He was either going alone, or not at all.

Complicating matters, the Limiting Factor is a prototype, designed and built using exotic parts—the most important one a spherical titanium pressure hull surrounded by a sleek cocoon of syntactic foam. The Limiting Factor’s chief designer, John Ramsey, simplified the sub’s electronics by basing its seafloor navigational capabilities on three $100,000 landers deployed from the Pressure Drop before launch. The sub triangulates position on the bottom by pinging modems on those landers, as well as the surface. The landers also serve as three additional science stations. They���re equipped with fish traps, push cores for sediment sampling, and “bio boxes,” where Vescovo can place samples plucked from the seafloor using the sub’s robot arm. (After every dive, Dr. Alan Jamieson of England’s Newcastle University—a specialist on the infrequently studied “hadal zone” and leader of the Five Deeps science team—will gather the samples for study. Jamieson also deploys his own landers, and thinks his team found four new species, all amphipods, in the Puerto Rico trench alone.)

Expedition leader Rob McCallum calls the Limiting Factor “the most significant vehicle since Apollo 11,” and while that’s a little hyperbolic, it’s not completely outlandish either. There is a reason no sub exists that can make repeat visits to the ocean bottom. They are expensive to build, and extremely difficult to engineer. Every part must be able to function at sea level, and also at 1,100 times that pressure, while protecting electronics that will be submerged in salt water, which corrodes metal at five times the rate of fresh water, for hours.

Really, Vescovo wasn’t just asking to pilot the Limiting Factor; he was asking to become a test-pilot of a sub that was still working out kinks two days before his dive. Initial tests in August were fraught with issues. Vescovo reached 5,000 meters (16,400 feet), and the sub was certified to that depth, but it went immediately back to Florida, where Lahey and his team took it completely apart to make changes.

On the Puerto Rican Trench mission, the first test, scheduled for December 15, was scratched because of a leaky hatch. A day later, with Lahey on board to make his final check of Vescovo’s piloting ability, the dive was scratched again for the same reason—after an extremely hairy launch and recovery in rough seas that caused Vescovo to lose his lunch. On the 17th, the two men managed to get the Limiting Factor to 1,000 meters (3,280 feet) on the leeward side of Puerto Rico, simplifying launch and recovery, but the hatch was still leaking slightly at the surface. There were also issues with the variable ballast system, two thrusters got smashed during recovery, and worst of all, the $350,000 robot arm that Vescovo would use to collect scientific samples from the sea bottom fell off and is now a very expensive sonar blip. “I’ve joked that this sub cost me an arm and a leg,” Vescovo said later. “Today, it literally cost me an arm.”

Expedition leader McCallum is a relentlessly cheerful but also very careful voice in the room. He was the expedition leader for Cameron’s Challenger Deep, and the leader for a number of missions to the Titanic, using Russia’s Mir subs. So when he called an all-hands meeting that night, most of us onboard expected him to announce that the mission was being postponed. Instead, he said that Vescovo had decided to go forward. Triton’s engineers would have until the morning of the 19th to repair the submarine, minus the arm (which wasn’t mission critical). If they could, Vescovo would go for it; if not, they’d call it off.

By early the next afternoon, Lahey was bouncing around the ship, radiating optimism. His guys, he said, had nailed it. They’d solved the hatch issue, rewired systems to fix a few mechanical bugs, and ironed out some communication problems. Heather Stewart, a Scottish marine geologist who is leading the mission’s seafloor mapping project, was convinced that she’d identified the absolute lowest point of the trench using data captured by the ship’s multi-beam echosounder, thought to be the most advanced sonar on any civilian vessel. And Jonathan Struwe, the German engineer from DNV-GL, which certifies submersibles, was satisfied that the sub was safe enough to go for it.

A crew from Atlantic Productions, embedded with Five Deeps to film a five-part TV series that will air on Discovery sometime in late 2019 or early 2020, cornered Paul-Henri “PH” Nargeolet—a veteran of deep sea exploration whose Five Deeps uniform patch reads “Legend”—to ask if he had concerns. Was this dive risky? “Yes and no,” replied the man who has dove on the Titanic wreck more than 30 times. “I would tell you it’s more dangerous to cross the street where you live than to dive past 4,000 meters. But, in the extremely rare chance [of an accident], you are dead before you know something happens.”

The next morning, McCallum gathered the troops one last time. “We have all worked very long and very hard to get to this point … the culmination of a dream that’s become a reality.” He acknowledged the many people who played a role: “Scientists give us purpose. Sonar tells us where to go. Filmmakers are telling our story. And the ship’s crew got us here…We just have to go and execute. The plan is pretty simple.” McCallum considered that and laughed. “He says, preparing to send a submersible to 8,400 meters under the sea.”

A few hours later, Vescovo was tucked inside Limited Factor, carrying out final safety checks. “If you’re happy, and life support is good, you’re free to dive,” Triton operations manager Kelvin Magee said, over radio.

“Life support good,” Vescovo replied. “Starting pumps … See you on the other side.”

Six hours later, at sunset, McCallum was there in a Zodiac raft to pluck him from the sub. “Welcome home, Victor,” he said, and drove him back to the Pressure Drop, where Lahey was furiously hugging his engineers.

Later, as Vescovo clutched a bottle of champagne, Lahey handed him a sheet of paper. “I’ve never given anybody one of these: a diploma for certified test pilot,” he said. “I distinctly remember my first dive in a sub. I went to 1,400 feet. You only went 20 times that far.”

Thursday a 'critical day' as crews continue search for missing Titanic submersible

Crews searching for a missing submersible headed for the Titanic offered no updates overnight into Thursday morning as the timeline for the remaining oxygen on board ticked down.

Wednesday began early with reports of undersea noise detected in the search are, though that yielded no further leads on the location of the missing vessel.

Sign up for breaking news alerts from CTV News

But Thursday marked the day the estimated oxygen supply on board is likely to reaching its maximum 96-hour mark.

The U.S. Coast Guard, which is leading the effort, did not provide updates on the search for the submersible, called the Titan, which went missing off the coast of St. John's early Sunday morning during a dive to the wreck of the Titanic.

The Associated Press reported the air supply is expected to end between 6 a.m. and 8 a.m. EDT today, based on the information given by the U.S. Coast Guard and OceanGate Expeditions, the submersible's owner and operator.

The Titan is carrying five passengers: Hamish Harding, a billionaire and explorer; Paul-Henry (PH) Nargeolet, a French explorer; Shahzada Dawood and his son, Suleman, members of a prominent Pakistani family; and OceanGate CEO and Titan pilot Stockton Rush.

'A CRITICAL DAY'

On Thursday, co-founder of OceanGate Guillermo Sohnlein wrote on Facebook, "today will be a critical day."

"I'm certain that Stockton (Rush) and the rest of the crew realized days ago that the best thing they can do to ensure their rescue is to extend the limits of those (oxygen) supplies by relaxing as much as possible," Sohnlein said. "I firmly believe that the time window available for their rescue is longer than what most people think."

Officials said Wednesday that efforts to find the submersible would scale up hour-by-hour overnight into Thursday morning.

The submersible was headed to the site of the 1912 sinking of the Titanic, located approximately 600 kilometres off the coast of Newfoundland at a depth of about 3,800 metres.

The crew aboard the support ship, the Polar Prince, lost contact with the submersible on Sunday an hour and 45 minutes into its dive.

OceanGate Expeditions, has been running tours to the British ocean-liner since 2021. Since the disappearance, details have emerged from a 2018 engineering report alleging issues with the submersible's structure.

On Tuesday, a Canadian aircraft picked up "underwater noises" from one area of the search. Officials quickly supplied the area with teams in hopes of finding the location of the submersible.

Canadian plane detects sounds in search for missing submersible

A Royal Canadian Air Force (RCAF) plane involved in a search for a missing submersible headed for the Titanic has detected "underwater noises".

Just after midnight EDT on Wednesday, the U.S. Coast Guard said on Twitter, both underwater and air searches were "relocated in an attempt to explore the origin of the noises." 

It's not clear whether the sounds are linked to the missing submersible.

Sign up for breaking news alerts from CTV News

Search crews are looking for a submersible carrying five passengers that lost contact with its surface ship the Polar Prince early Sunday morning after leaving St. John's, N.L.

The missing vessel is named the Titan and was heading to the 1912 wreckage of the Titanic, which is located about 600 kilometres off the coast of N.L. The tours are owned and operated by OceanGate, a U.S.-based company.

The submersible is carrying Hamish Harding, a billionaire and explorer, Paul-Henry (PH) Nargeolet, a French explorer, Shahzada Dawood and his son Suleman, members of a prominent Pakistani family, and OceanGate CEO and Titan pilot Stockton Rush.

The U.S. and Canadian coast guards and RCAF have crews looking for the vessel that lost contact an hour and 45 minutes into the expedition.

Officials said Tuesday afternoon at 1 p.m. EDT there was enough oxygen remaining on board the Titan for only 40 hours.

"This is a complex search effort which requires multiple agencies with subject matter expertise and specialized equipment," Capt. Jamie Frederick of the U.S. Coast Guard told reporters during a press conference in Boston on Tuesday.

The sounds discovered by a Canadian aircraft are the first potential lead in the case since the search started.

  This is a developing story.

  Canadian P-3 aircraft detected underwater noises in the search area. As a result, ROV operations were relocated in an attempt to explore the origin of the noises. Those ROV searches have yielded negative results but continue. 1/2
