Titanic tourist sub goes missing in Atlantic Ocean, June 2023 #2

[JennieM]

Locating sonar noise is like trying to pinpoint a snare drum in a packed concert stadium, dive expert says​

Various environmental factors in the ocean are likely complicating efforts to identify noises heard on sonar as the search for a missing submersible continues into its fourth day, according to one diving expert.

Rick Murcar, who is the international training director for the National Association of Cave Divers and the owner of Aquatic Adventures of Florida Inc., explained that sound travels faster in the water — which is making it more challenging for rescuers to pinpoint where it is coming from.

Things like the currents can deflect the sound so that it appears like it is coming from miles away from where the actual source is.

The Coast Guard said an aircraft picked up on noises Tuesday and Wednesday in the Atlantic Ocean. It relocated equipment to the area, but so far, efforts to figure out what was making the sound have not yielded any results, the Coast Guard said.

Murcar said to think of this effort to locate the noise as trying to pinpoint a specific drum in a stadium full of cheering fans and other instruments.

“Picture a massive stadium that has a roof on it, and you have an aircraft flying over top and it drops sensors down to listen to the sound inside that stadium,” he said. The person inside the stadium is playing a snare in a constant, beating pattern, in addition to all of the other drums he has, Murcar said.

Now, to narrow down the location of that snare, he said, analysts have to first get rid of all of the other environmental noises.

“They have to negate any aspect of the impact that the boating plays into the equation,” he said. In the stadium analogy, this would be things like the fans, the guitars and the keyboards.

“And then we’re going to put it in the dark,” Murcar said. “Once they can actually get down to where the drum set is, and the couple square feet that that's taking up, they have to negate each and every individual drum to find the very distinctive one that tells them it's a piccolo snare."

"Then they're going to go look for it with an ROV (a remotely operated vehicle) — with a flashlight in their hand,” he added, completing the analogy.

June 21, 2023 - Missing Titanic sub search news

A massive search operation is underway in an area twice the size of Connecticut for the submersible that went missing Sunday — as officials fear there's less than a day's worth of oxygen left on board the craft.

Lack of food, lack of sanitation and frigid conditions are also concerning in addition to lack of oxygen if this vehicle is still intact

Add in the mental distress of the position they are in. It's like a scifi horror movie

Dr Boxall said a distress signal from the submarine has been sent out.

He told PA: “This is second-hand knowledge but my understanding is that they have received a signal from the submarine.

“You can’t use radios underwater.

“You rely totally on ‘pings’. What they have is really limited communication.

“Apparently they have had, and I don’t know when, they have had an emergency ping saying the vessel is in distress.

“I don’t know if that is automatically generated or generated by people on board.

“It could be that the vessel is lost already or it could be automatic.”

He said he did not know when the message was transmitted.

What we know about the missing Titan submersible and those on board

Here is what we know so far about the missing 22ft long vessel and those on board, including the British billionaire adventurer Hamish Harding.

wonder what ths means.... if they had a distress signal, wouldn't they have coordinates? So is this something new or just a bad news report that is confusing? All the other sources say "no info from the vessel since Sunday after 1hr and 45 mins...."

I don't understand how they don't know how many food rations they have aboard.

This information should be readily available. It sounds like the Titan organisers don't know themselves? That's quite concerning in terms of Titan's overall organization if that's the case MOO.

I doubt the sub has much in the way of food rations. The uncertainty would be in that they don't know if the individuals took snacks with them or not.

The host of Expedition Unknown on Discovery did a brief dive in the Titan prior to their first dive to the Titanic and was going to do an actual dive with them to the Titanic but backed out due to safety concerns.

Horizon Maritime, the Canadian company that co-owns the Polar Prince research vessel that launched the Titan sub, has released a statement following the press briefing.

The company said it was working to “ensure every possible effort is put into bringing people home”.

More noises heard in search area, says US Coast Guard, amid huge effort to bring crew home – as it happened

Rescue team says every noise being tracked and analysed; ‘every possible effort’ being made to bring missing crew home, says Polar Prince co-owner

I doubt the sub has much in the way of food rations. The uncertainty would be in that they don't know if the individuals took snacks with them or not.

They were all asked to restrict their diets before the trip.

With zip loc bags as a ‘toilet’, it was necessary to cut down on edibles and potables.

There probably wasn’t much onboard, they expected to be back onboard the ship in a few hours.

The French Navy vet should be able to send/bang a Morse code that could be differentiated from the banging of the Titanic. a navy vet would know that rescue teams are listening for sounds.

Are French Navy taught morse code? US Navy sailors are not.

Here it is…but the whole system could have failed…

The Titan has an array of signals, lighting, reflectors and other equipment it can use once on the surface to attract attention.

Thank you for finding it!!!

Wow. This is stunning, especially considering his history of risk taking. He knew.

Missing Titan sub battery suddenly DRAINED during 2022 Titanic trip

A YouTuber who once traveled to the Titanic on the missing Titan sub shared how the vehicle's batteries suddenly drained during the expedition, forcing it to end early.

Are French Navy taught morse code? US Navy sailors are not.

It's a standardized form of communication that was used well into the 1990s. I'm thinking it's more than probable Nargeolet learned Morse Code when he was trained as a sailor 50-some years ago.

And it is still taught to select groups in the US Navy. It may not be widely-used, but it's not defunct, either.

Morse Code (1836)

The Universal Language of Morse Code, was designed by Samuel Morse, an American inventor and painter, Alfred Vail, an American machinist…

This may sound horrible, but at this point, I am hoping they imploded because then they wouldn't have been aware. The thought of them trapped, and trying to bang as they run out of air, seems like such a hellish situation.

Agree. Your post reminded me of the Elliot Lake mall collapse in Canada, and the poor lady knocking for help till she passed. Heartbreaking.

Sort of macabre, visiting the Titanic, and ending up not coming back. I personally think, leave the sea graveyard alone. Going that deep in the ocean isn't like snorkeling on vacation. It shouldn't be some sort of "tourist" excursion.

I’ve said the same. Imagine sitting there watching everyone around you slowly die. Then it’s your turn.

I do think this happened quickly though, and don’t believe those bangings are from them. Well, I sure hope not.

It always has blown my mind that we as a species have explored further into outer space than we have in the oceans.

It could be recharged via a battery pack, if someone brought one, but carbon fiber is a really effective blocker of cell/RF signals. The Titan’s hull is made of 5ft-thick carbon fiber (and titanium).

5 INCH think not 5 FEET thick...

"The fact that rescue crews haven't spotted the vessel on the ocean's surface might mean that the Titan is snagged or its 5-inch-thick carbon fiber hull was penetrated, Pogue said."

That's why I asked. How is the Titan supposed to contact anyone now that this has happened? Once they are at the surface? They can't get out, they can't yell, they can bang. They can barely be seen, painted white, in a vast field of white and black and blue.

The method of contact has to be automatic, IMO. No one can get out of the Titan and light a flair. I don't think it would have automatic flairs in a wet environment anyway (although surely some kind of device could have been invented - I just have not heard about anything other than very basic tools, such as a cell phone - which right now, is not working).

IMO.

I wondered why the sub wasn’t painted bright orange with manual reflectors like cruise ship life boats and reflectors? Agreed with the sea swell and white cabs of several feet, the white sub would decently blend in with the sea, but bright colors might stand a chance of being seen.

also once on surface, I would think all of the cell phones, watches etc would be drained down by now, especially with a power outage onboard, so no way to communicate Unfortunately.

I found this fellas YouTube video re: his trip but I don’t know how to change it to English.

Is anyone able to either translate it or play It in English.

East to find. Thanks
