US NAVY ACOUSTIC SYSTEM DETECTED ‘ANOMALY’ THAT WAS LIKELY IMPLOSION, OFFICIAL SAYS

A U.S. Navy acoustic system detected an ‘anomaly’ Sunday that was likely the Titan’s fatal implosion, according to a senior military official.

The Navy went back and analyzed its acoustic data after the Titan submersible was reported missing Sunday. Coast Guard officials on Thursday announced that the craft suffered a catastrophic implosion, killing all five aboard.

That anomaly was “consistent with an implosion or explosion in the general vicinity of where the TITAN submersible was operating when communications were lost,” according to a senior Navy official.

The official spoke on condition of anonymity to discuss a sensitive acoustic detection system.

The Navy passed on the information to the Coast Guard, which continued its search because the Navy did not consider the data to be definitive.

The Wall Street Journal on Thursday first reported the Navy’s involvement.

TITANIC SALVAGE RIGHTS OWNER MOURNS LOSS OF SHIPWRECK EXPERT

RMS Titanic, Inc., the company that owns the salvage rights to the Titanic shipwreck, is mourning the loss of Titanic expert Paul-Henri Nargeolet, who was among five people killed aboard the Titan submersible when it imploded this week.

Nargeolet — known as “PH” — was a long-term employee of the company.

“The maritime world has lost an iconic and inspirational leader in deep-sea exploration, and we have lost a dear and treasured friend,” the company said in a statement Thursday.

Friend and former colleague Matthew Tulloch said Nargeolet loved his work from the time they collaborated in the 1990s up until Nargeolet’s death.

“I never got the impression that he was looking forward to retirement,” Tulloch said with a small laugh. “You sort of think of people as they retire, then they can go on and do things that they love to do. This was exactly that for him — I can’t think of anything that I’m aware of that he would enjoy doing more than traveling around and sharing information and his experiences with people.”

WHITE HOUSE OFFERS CONDOLENCES TO FAMILIES OF TITAN VICTIMS

The White House offered its condolences to the families mourning the five people killed aboard the Titan submersible.

U.S. Coast Guard officials announced their deaths Thursday following the vessel’s catastrophic implosion in the North Atlantic.

“Our hearts go out to the families and loved ones of those who lost their lives on the Titan,” the White House said in a statement. “They have been through a harrowing ordeal over the past few days, and we are keeping them in our thoughts and prayers.”

The statement also thanked the searchers, including the Coast Guard, involved in the international effort to find the submersible.

“This has been a testament to the skill and professionalism that the men and women who serve our nation continue to demonstrate every single day,” the statement said.

“TITANIC” DIRECTOR JAMES CAMERON SAYS DEEP-SEA EXPLORERS VOICED CONCERNS ABOUT TITAN

“Titanic” movie director James Cameron says the Titan submersible tragedy has eerie parallels to the ocean liner’s disaster more than a century ago.

Debris from the submersible’s catastrophic implosion, killing all five aboard, was discovered near the shipwreck.

In an interview with ABC News, Cameron said he was “struck” by the similarities. The Titanic’s captain ignored warnings about ice in the North Atlantic, and the movie director said deep-sea explorers voiced concerns about the Titan submersible, saying it was too experimental to carry passengers.

“To take place at the same exact site with all the diving that’s going on all around the world, I think it’s just astonishing,” Cameron told the TV station. “It’s really quite surreal.”

Cameron had previously traveled to the Titanic wreckage, including on Sept. 11, 2001, in a submersible vessel.

PAKISTAN OFFERS CONDOLENCES TO FAMILY OF FATHER AND SON ABOARD IMPLODED SUBMERSIBLE

Pakistan has offered the country’s condolences to the Dawood family after the father-and-son explorers were among five killed when the Titan submersible imploded deep in the North Atlantic waters during a trip to the Titanic’s wreckage.

Pakistani nationals Shahzada Dawood and his son Suleman were aboard the Titan when it went missing Sunday. Authorities on Thursday said the catastrophic implosion meant there were no survivors.

The Dawoods are members of one of Pakistan’s most prominent families and their firm, Dawood Hercules Corp., based in Karachi, is involved in agriculture, petrochemicals and telecommunication infrastructure.

“Our deepest condolences to the Dawood family and the family of other passengers on the sad news about the fate of Titanic submersible in the North Atlantic,” Pakistan’s Foreign Ministry wrote on Twitter. “We appreciate the multinational efforts over the last several days in search of the vessel.”

COAST GUARD SAYS SOUNDS HEARD DURING SEARCH LIKELY UNRELATED TO TITAN SUBMERSIBLE

The Coast Guard says underwater sounds and banging noises detected in the search area for the Titan were likely unrelated to the missing submersible.

The sounds, heard over two days, gave hope to searchers and those watching the massive effort unfold since Sunday, when the vessel was reported missing, but ultimately seems irrelevant.

Experts say the ocean floor is a “noisy” place and a potential connection between the banging and the Titan was unlikely.

Debris from the Titan, which suffered a catastrophic implosion that killed all five men aboard, was found near the Titanic shipwreck deep in the North Atlantic waters.

“There doesn’t appear to be any connection between the noises and the location on the seafloor,” Rear Adm. John Mauger of the First Coast Guard District said Thursday.

COAST GUARD WILL CONTINUE SEARCHING SEA FLOOR FOR CLUES ABOUT WHAT HAPPENED TO TITAN

The Coast Guard will continue searching the sea floor near the Titanic shipwreck for more clues about what happened to the Titan submersible deep in the North Atlantic waters.

Officials say there isn’t a timeframe for when they will call off the massive international search. Rear Adm. John Mauger, of the First Coast Guard District, said search efforts will continue but that the prospect of finding or recovering remains was unknown.

Much of the search is being done by remotely operated underwater vehicles known as ROVs that can scan the sea floor.

“This is an incredibly unforgiving environment down there on the seafloor,” Rear Adm. John Mauger of the First Coast Guard District said Thursday.

TITAN’S DEBRIS FIELD WAS FOUND NEAR THE TITANIC SHIPWRECK, COAST GUARD SAYS

Coast Guard officials say the Titan’s debris field was discovered near the Titanic shipwreck but it’s too early to tell exactly when the catastrophic implosion occurred.

The Titan submersible was reported missing Sunday – eight hours after it initially lost contact with its surface ship – and its 96-hour oxygen supply would have run out Thursday morning.

It’s not clear whether the implosion occurred Sunday or in the days following, during an international search effort to find the missing submersible.

The Titan’s debris field was located roughly 1,600 feet (488 meters) from the Titanic.

TITAN SUBMERSIBLE LIKELY IMPLODED AND THERE WERE NO SURVIVORS, COAST GUARD SAYS

The Coast Guard says the Titan submersible likely imploded in the North Atlantic waters and there were no survivors among the five people aboard.

The implosion likely occurred near the Titanic shipwreck, where the submersible was headed.

“The debris is consistent with the catastrophic loss of the pressure chamber,” Rear Adm. John Mauger, the First Coast Guard District, said Thursday. “Our most heartfelt condolences go out to the loved ones of the crew.”

COMPANY LEADING TITANIC EXPEDITION SAYS FIVE PEOPLE ON MISSING SUBMERSIBLE BELIEVED TO BE DEAD

The company leading the Titan submersible trip to the wreckage of the Titanic says the five missing crew members are believed to be dead.

OceanGate Expeditions on Thursday says its pilot and chief executive Stockton Rush, along with passengers Shahzada Dawood and his son Suleman Dawood, Hamish Harding, and Paul-Henri Nargeolet “have sadly been lost.”

OceanGate did not provide details Thursday when the company announced the “loss of life” in a statement or how officials knew the crew members perished.

The vessel’s 96-hour oxygen supply likely ended early Thursday morning.

The company has been chronicling the Titanic’s decay and the underwater ecosystem around it via yearly voyages since 2021.

8-HOUR TIME DELAY TO REPORT MISSING TITAN RAISES QUESTIONS

Questions remain about the eight hours between when the Titan lost communication with the surface and when its Canadian support vessel reported it missing to the U.S. Coast Guard.

The time delay has yet to be explained by the company that owns the submersible, OceanGate Expeditions.

Sean Leet, head of the company that co-owns the Titan’s support ship, has refused to discuss the timeline, saying only that “all protocols were followed for the mission.”

But experts familiar with deep-sea exploration say those lost hours raise red flags.

The submersible used a rudimentary system that basically communicated with the surface ship through text message, and likely lacked an emergency radio beacon that could have floated to the surface and started beeping if there was an emergency.

The vessel had lost communication with the support ship, Canadian research icebreaker Polar Prince, during previous dives.

PAST DEEP-SEA RESCUES SHOW CHALLENGES FOR TITAN

The search for the Titan submersible has drawn attention to other deep-sea rescues, only some of which ended in lives being saved.

Those successful efforts — from a submersible off Ireland to a submarine off the New Hampshire coast — offer some measure of hope for the passengers and their families.

But many ended with some, if not all, the passengers on board dying — demonstrating the inherent risk of operating in the deep ocean.

Either way, those rescue missions were not as complex as the effort to find the Titan submersible. They were often in shallower waters and, in several cases, were much bigger crafts.

For example, the USS Squalus sank off the coast of New England in 1939 during a test dive, due to a catastrophic valve failure that partially flooded the military submarine. A newly developed rescue chamber was lowered into the water to famously save the surviving 33 crew members. Twenty-six others drowned in the initial accident.

But the Titan is a civilian vessel and would not have standard Navy hatches that could attach to a rescue chamber like the one used for the Squalus. That makes it almost impossible to rescue any of the submersible’s occupants if they are found underwater.

SEARCH FOR TITAN SHOWS NEED FOR MORE DEEP-SEA TECH

An underwater researcher says the search for the Titan shows the desperate need for more deep-sea technology in the U.S.

The unsuccessful efforts have “really opened up people’s eyes that we need a much more robust capability over larger areas of the ocean to be able to detect and sense where things are,” said Nick Rotker, who leads underwater research for non-profit research and development company MITRE.

The U.S. needs more underwater robots and remotely operated underwater vehicles, known as ROVs, to ensure safety, he said, especially as private exploration of the ocean expands.

“The issue is we don’t have a lot of capability or systems that can go to the depth this vessel was going to,” Rotker said.

Several ROVs are in the North Atlantic waters to search for the missing submersible. One found a debris field near the Titanic wreckage that could be linked to the Titan. The debris field was discovered by a robot from a Canadian vessel.

DEBRIS FIELD DISCOVERED BY DEEP-SEA ROBOT

Officials say a remote-operated robot discovered the debris field near the Titanic that could be linked to the missing Titan.

The robot is one of several remotely operated vehicles, known as ROVs, scanning the sea floor for clues of the missing submersible.

The ROVs are outfitted with cameras and travel to depths many other vessels cannot and have been used for undersea exploration for decades.

The Coast Guard’s post on Twitter gave no details, such as whether officials believe the debris field is connected to the Titan.

The Titanic wreckage is located at a depth of 12,500 feet (3.8 kilometers) in the North Atlantic waters.

The Coast Guard has scheduled an afternoon news conference in Boston to discuss the ROV’s findings.
