Even if they locate them I doubt if they have any way of recouvering the ship at that depth. God bless their souls.

[Victoria Watcher]

Perhaps the best we could hope for is it had a breach and they died quickly. Rather than they are going to die slowly as they run out of oxygen.

[Victoria Watcher]

Here's what we know about the crew so far:

 

 

• Hamish Harding: The British businessman and adventurer is based in the United Arab Emirates. He owns a company called Action Aviation that buys and sells aircraft including business jets, and which confirmed he was on board the submersible on Sunday. Harding was a passenger on Blue Origin’s June 2022 space flight, and was one of the first people to travel the Challenger Deep in the Pacific Ocean — the deepest known point on Earth.
• Paul-Henri Nargeolet: Harding posted on social media Saturday that diver Nargeolet was scheduled to be on Sunday's trip with him. CBC News spoke with Larry Daley, a St. John's-based diver, who also said Nargeolet was on the expedition. CNN has attempted to reach out independently to Nargeolet with no success. Nargeolet has led several expeditions to the Titanic and supervised the recovery of many artifacts from the wreck, according to the E/M Group, where Nargeolet was director of underwater research.
• Shahzada and Sulaiman Dawood: The Pakistani businessman and his son were also on board, according to a statement released by the family on Tuesday. Shahzada is a trustee of the SETI Institute, a research organization in California, according to its website. He is also vice chairman of Dawood Hercules Corporation, part of the Dawood Group, a conglomerate of various businesses owned by the family.

Here is an animation with sea depths of wrecks, it's quite good.  Titanic is about 4:20 in.

The Queen of the North is not included, but for reference it's sitting in about 425m of water.

 

 

 

 

 

In 1968 this US navy nuclear sub went down forever with 99 crew onboard.   It's in 3,000m.

The U.S. Coast Guard Northeast has announced Tuesday morning that 10,000 square miles have now been searched in the hunt for the missing OceanGate Titan submarine, which vanished Sunday during a dive to the Titanic wreck site.

"A Canadian Aircraft P3 Aurora has arrived on scene to conduct sonar searches," it said. "The R/V Polar Prince and R/V Deep Energy are continuing their surface searches."

Not so sure a surface search is what is required here.

The CEO of OceanGate Expeditions, Stockton Rush, is on board the missing submersible that vanished during a mission to explore the wreckage of the Titanic, the company said Tuesday.

There's just 41 hours of oxygen supply left on the missing vessel, which is carrying five people, a U.S. Coast Guard official said Tuesday as the search for the Titan submersible continues.

The submersible is part of an OceanGate Expeditions tour that offers passengers a once-in-a-lifetime experience to explore the Titanic wreckage. It went missing Sunday after losing contact with the research vessel Polar Prince.

British billionaire and owner of Action Aviation Hamish Harding was also among the five people onboard the vessel, along with prominent Pakistani businessman Shahzada Dawood and his son, Suleman.

You would think a vessel that advanced would have multiple ways to communicate with its mothership, right? That there is total silence is not a good sign.

[Victoria Watcher]

Was this thing operating out of Canada because it would not be permitted in the US?

[Victoria Watcher]

Earlier on Tuesday, it was announced the French research vessel Atalante was asked to provide support in the ongoing search for the Titan submarine.

 

The Atalante is within 48 hours of navigation from the Titanic wreck location.

 

On board is the autonomous robot Victor 6000, which can dive to the depth of the wreck.

 

Atalante is due to reach the area where the search operation is taking place about 20:00 (00:00 GMT) on Wednesday.

The remotely operated submersible Victor 6000 offers the scientific community a deep-water device (6000 metres) which can:

• Undertake operations to watch and explore;
• Study areas that require video and acoustic inspection;
• Manipulate objects and carry out physicochemical measurements in position;
• Sample water, sediment and fauna;
• Undertake deep-water missions on, for example, shipwrecks.

Victor 6000 is a modular and remotely operated deep-water system fitted with instruments. It can generate high-quality optical imaging, as well as carry and operate a diverse range of scientific equipment and tools.

 

The submersible is connected to the ship by an electromechanical cable which is 8,000 metres long and supplies 20 kW of electrical power. Optical fibres in the cable send the data and image flows to the surface, thus providing the pilots and scientific teams with complete access. The control room, housed in a 20’ container placed on the ship, enables the submersible to be piloted in real time. In theory, there is no limit to the duration of a dive, which means the pilots can adopt a 4-hour watch system (2 people per watch).

 

 

 

 

 

 

 

Unless it can grab the other sub, hard to know how this will help.  But it's something I guess.

A couple of submersibles are heading to Victoria, UVic says. Somewhat unfortunate timing, news-wise.

Droids of the deep: ocean expedition sets sail next week

Two robots are on their way to Victoria as part of Ocean Networks Canada’s #ONCAbyss Summer Expedition that begins next week.

Ocean enthusiasts all over the world will be able to remotely join the deep-sea exploration in the northeast Pacific, and see this underwater world illuminated by remotely operated vehicles (ROVs) Hercules and Atalanta streaming live 24/7 at NautilusLive.org. Viewers will also have a topside view to watch the dive mobilizations, and the opportunity to connect directly with the team through livestream events.

ONC, an initiative of the University of Victoria, in partnership with Ocean Exploration Trust (OET) will launch the 22-day expedition aboard the Exploration Vessel Nautilus on June 25—marking the seventh year in the partnership between the two ocean tech powerhouses.

What: #ONCAbyss Summer Expedition Press Event.
When: Sunday afternoon, June 25, 2023. Exact time and location will be emailed to registrants.
Register now
Note: Covid protocols will be in place.

The new-to-Victoria one-tonne ROV Atalanta, will provide a bird’s-eye view of the revisiting 2,950 kilogram main ROV, Hercules, as it works on the seafloor, maintaining ONC’s 800-plus kilometre NEPTUNE ocean observatory located off the southwest coast of Vancouver Island. The two ROVs will dive at multiple locations, from the abyssal plain region of Cascadia Basin to the smoking chimneys of the Endeavour hydrothermal vent field. Explore all five sites in this map.

Members of the media are invited to the expedition mobilization where cranes will load cutting-edge ocean exploration equipment and instruments on the E/V Nautilus.

The following representatives will be available for interviews:
● Meghan Paulson, ONC director, observatory digital operations
● Allison Fundis, expedition leader & OET chief operating officer
● Josh Chernov, expedition operations leader & OET ROV operations manager
● Kate Moran, ONC president & chief executive officer

ONC’s ocean monitoring helps us understand the changes occurring in the ocean, and its role in moderating and potentially mitigating climate change. ONC’s ocean data reveals the dynamics of ocean and Earth processes and cycles across time-scales–from hours and seasons, into decadal scales –supporting research on complex Earth processes in ways not previously possible.

A B.C. businessman and philanthropist is speaking out about his experience with OceanGate — the company whose submersible went missing during a mission to view the Titanic shipwreck Sunday.

 

Ron Toigo said during his first trip on the vessel they also got stuck at the bottom of the ocean.

 

“You still felt pretty safe, though,” he said.

 

__________________________________________________

 

Toigo said he appreciated how many safety precautions were taken before the expedition got underway.

 

“You spend your first number of days there really going over everything that could go wrong and how you’re supposed to respond and being prepared for whatever happens,” he said.

 

“You’re really set up for five or six days if you had to stay at the bottom until they had to come and get you with a Navy sub or something.”

Perhaps he has not heard, there is lots of navy there, but nobody brought anything that can "come and get them".  "Navy subs" at best go down around 600m.  Not 4,000.

Interesting video, I didn't know that the Carpathia which rescued the Titanic survivors went down herself 6 years later.

[LJ]

There were safety problems earlier in the program and the hull can suffer from cyclical pressurization, which can weaken the hull.

 

I'm guessing it imploded about two hours in, and you're looking for little bits and pieces.

It's not the first time that they have had communication problems, previous dive they were out for a couple of hours.

In fact the diving depth of a naval submarine - specifically western nuclear submarines and_really _specifically the capabilities of US and RN nuclear subs - remain among the most highly classified military secrets in the 21st century. Unless you are the USN CNO or the submarine's CO anyone who claims these boats 'go only to x depth' is either lying or simply proving they don't know. 

 

For decades the USN claimed only that their submarines operated "below 400 feet" which naturally evoked lots of smirks and smiles and lots of knowing giggles. At that depth the keel is barely getting wet. The British did likewise typically. Fact is their actual capabilities are closely held national secrets and all manner of dive capability and performance numbers can and will be released periodically into the public realm, as in this article, and no one aside from the handful of people involved in the boat's design and its physical operation, really knows the truth for sure.

 

One interesting issue with the OG submersible - and note it is a submersible and not a submarine, which is an entirely different beast altogether so the terms should not be used interchangeably - that is coming to light now are the fears supposedly raised by some its earliest test crew about the fact it only had 5" thick steel pressure hull instead of the 7" that was expected. 

[lanforod]

I wouldn’t be surprised at all if some Navy subs have deep depth submersibles they can launch as well. Seems those would pair well and could have tactical purpose too.

A Canadian military surveillance aircraft detected underwater noises as a massive operation searched early Wednesday in a remote part of the North Atlantic for a submersible that vanished while taking five people down to the wreck of the Titanic.

Remote part of the Atlantic, eh? So what do they call the part of the Atlantic not off the coast of the eastern seaboard?

I believe Biden calls it the Indian Ocean.
