How horrifying that a submarine carrying 5 people has gone missing. Apparently there’s only 96 hours of air on the submarine when it sets off. The people on board must be terrified! [[https://www.bbc.co.uk/news/world-us-canada-65953872.amp https://www.bbc.co.uk/news/world-us-canada-65953872.amp]]

That's just not true though. They're looking at how the wreck degrades over time due to the effect of metal eating bacteria. They're also looking at how reefs form over time and what life lives at these enormous depths (last year they announced the discovery of a volcanic reef discovered near the site of the wreck). It wouldn't be possible to do this at a site other than the Titanic as there is nowhere else in the world that people will pay to go back to again and again.

Whether you think this is important or not it's false to say that they're not contributing anything scientifically. I think it's also fair to say that the huge majority (if not all) human innovations are built on the shoulders of hobbies, failed experiments and "useless" endeavours that turned out to be anything but useless.

And on that we’ll have to differ - none of the tourists on board are qualified to make those assessments. Unfortunately it looks like this tourism will claim their lives.

The Magellan crew are apparently waiting for the US to approve their flight to Newfoundland to get their winch vehicle underway. What's stopping them flying and getting there just in case the US has a change of heart?

If it hasn't imploded then that leaves stuck at the dive site; stuck on surface; trapped midway down?

I've read that they have communications and signalling equipment, which can be used at the surface, so it seems unlikely.

The daily mail (sorry!) are reporting that contact was lost at 5.45am, but a last distress signal was sent at 10am, I hadn’t heard that before now?

quitezen · 20/06/2023 13:53

I read that about a distress signal (sky news I think) but they didn't know the time it had been sent.

whatsappdoc · 20/06/2023 13:53

Just seen BBC News have reported a pipe-laying vessel is in the vicinity and has equipment to reach that far down. Fingers crossed the Titan can be found.

I've been out at sea with ROV Jason twice, and a few other cruises with different ROVs, but Jason is the one that I have most experience with. It's run, like Alvin, by Woods Hole.

Now I'm really jealous!

The tethered ROVs I work (not as in operate) tend to be recovered every two to three days, as they have heavy maintenance schedules. The cooling oil in the batteries tends to need regular changing, for example and things often break down. Occasionally, they lose comms, because a fibre optic cable has broken

AUVs tend to do a maximum of 60 hours and can send a continuous stream of data in binary, using sonar signals. It's degraded, but if you know side scan sonar and chirp etc, you can see the seabed in a reasonable way.

It has all kind of imaging systems, sonar, lights and video system and it's all streamed to the ship in real time. There are screens pretty much everywhere on the ship and you can see what is going on at the seafloor at all times, it's great. For the cruises I've been on there were always platforms down with the ROV that samples could be loaded onto, and that carried additional equipment, and which could be brought up while the ROV stayed down. The ROV operated 24 h, with pilots, navigators and scientists divided into shifts so that there was always a team running the ROV, until the cruise ended, or the ROV needed to be brought up because a storm approached. There is nothing better than being out at sea on a ship full of scientists and crew all working together.

Your posts are absolutely fascinating x

The trouble is, they are looking a small metal object lost amongst a vast debris field of the wreck - to a sonar, all objects will be much the same. How do you tell the difference between the signature of the Titan - a large metal cylinder - and a titanic boiler - a large metal cylinder.

like one of the experts said in the BBC - it’s like looking for a mine in a minefield.

Re the 19 year old, ok by definition he's not a child but he's still very young. It's all too sad. Can you imagine how their immediate and extended family are feeling right now 😢

They didn't confirm at what depths its ROV can work, or if it has any form of winch.

But I'm really hoping it is up to the task

Maybe I'm taking too much from what I've seen in Submarine movies, but won't the sonar be able to pick up different noises it's making? Like anything electrical/mechanical still operating and hopefully voices and any other noise the occupants are making? Won't that set it apart from all the lifeless chunks metal down there?

BillyNoM8s · 20/06/2023 14:00

I hadn't read anything about distress signals until just now. I thought it just disappeared.

I'm no fan of the billionaires but I shiver at the thought of any fellow human in this terrifying situation.

Why would the us prefer to use a different one do we know?

I wondered if some of the family are on the vessel that took them out to the dive site. Id hate to think the mother is onboard waiting for new of her son and husband and I can't imagine the staff would have training on how to deal with supporting the family I'm these circumstances. It must be awful.

Sky seem more optimistic:

”Our OSINT editor Adam Parker says crew on board will be searching the seafloor using cameras, and are usually laying pipes deep underwater.
Deep Energy, built 10 years ago, sails under the Bahamas flag and supports subsea developments in the North Sea.”

So they may be focussing on the locating of it - even if they can’t get to it themselves?

And my point is you would never get the funding for this kind of work without the money provided by tourists who want to come along for the ride. Missions like this are hugely expensive. Actually it's not my point, it's what the CEO said in the video posted upthread. It seems reasonable to me though.

I'm not naive enough to think that the guy solely motivated by scientific curiosity. I'm sure there's a healthy dose of love of exploration, adventure and probably a wish to make money but to say they've uncovered nothing of scientific interest or that they could have achieved it using unmanned vehicles is false.

That might be worse for those inside the titan?! Seeing something looking for you and then not being able to rescue you

Igneococcus · 20/06/2023 14:08

@SinnerBoy
Jason gets its power via the cable from the ship, so there is no need for batteries. It's really a fantastic ROV and if were planning to put in a grant application for a cruise I'd ask for Jason, not Alvin, you just get so much more work done.

Are they waiting?
Why?
If the sub went down on Sunday 8am GMT and they can last 56hours ( with 5 people ) and that’s assuming none of them are panicking as that will use up more oxygen what are they waiting for.
News stated it takes 8hours to get to the bottom plus the time to get them back up again. Why would you wait to, every second counts at the moment.
If they went under at 8am then they have 2 hours left.!! Max.

Hoping and praying for a miracle.
