Hopefully a good outcome ahead.
Sub named Titan.
I know the media make up curses The Curse of King Tut, The Kennedys etc. But the Titanic does seem to have a bit of a 'mi adh' attached to it still.
They've announced they've heard banging every half an hour and there's a 77 year old French guy on board.
Has there been anything tethered since the 1940s and beyond 1000m ?
If I knew I had 24 hours left I'd probably like to do a bit of banging too 🤭
can any of those survive 4000m of pressure, or will they work from inside the vessel?
An EPRIB wouldn't work from those depths, full stop. It needs to be at the surface. You could release an EPIRB from depth that might start transmitting once it reaches the surface but at that point its no longer attached to the sub and will drift with winds, currents etc. All it would tell you is that somewhere 3-4km below at some point in the general vicinity there is a sub. But they know that already.
Seems crazy in hindsight not to have a locator on the submersible, I'm sure we're only taking about a few dollars to have one, and yet it doesn't. That is not right.
The end of Titanic Tourism we may expect.
No chance... if they had them, they would need to be carried internally, and as the poster above says, would only work on the surface (and even that would be difficult as it'd need to be kept inside the capsule, so signal might not even make it up to space).. id say once one of these goes even just a few cm under the surface they'd no longer be able to reliably transmit a signal.
A new exhibit in Belfast's Titanic Museum more likely
I'd imagine if they could have one for a few dollars that could survive the pressure and still work upon resurfacing, they'd have it. Anything capable of going to 4000m down is big bucks. As I understand it, they cannot have any device that requires a connection between inside and outside the vessel as it would compromise the integrity of the capsule, which is also why they can't release the hatch from inside.
If the sub is found and the occupants rescued, that Oceangate fella Stockton Rush ought to thrown back into the sub head first and the hatch bolted shut and the whole contraption sent back down to the bottom.
I'd be wondering now at this stage, with desperation, darkness and claustrophobia, would some desperate struggle have broken out on board? Might one or two plot to finish off the others to save oxygen?
Might someone one of them sabotage the stricken the sub to end their suffering, taking the others with them?
Might the whole tragedy be a result of a claustrophic panic by one of the occupants, who went apesh!t in the sub and accidentally damaged the equipment, paralysing the sub? Might it have been a suicide attempt by one of the occupants who sabotaged something? Or deliberately opened a valve or did something to scuttle the sub, taking everyone on board with them?
Yeah. Maybe there is nothing wrong at all, and they are just down there having a good-time orgy amongst themselves.
God bless your imagination.
Technical question: Apparently a Canadian plane heard the banging noise. What do the planes use to listen for underwater noise?
Her sister ship barely gets a mention, it's only 122m down, much more to see I'd imagine and much safer to visit.
The third of the ships was scrapped with little fanfare.
Put any of these ships alongside a modern cruise ship and they would look tiny and nobody would be interested in them.
Good.
There's something very ghoulish about this.
I think tourism on these wrecks is wrong. I'd suggest a way to stop this sort of voyeruistic "tourism" of mass grave sites would be to destroy the wreck, blow it out of existence. Look it is a famous story but that's all - the titanic is not notable in any way other than the story surrounding it. Hundreds if not thousands of very similar ships were sunk in the first half of the 20th century by torpedos. I think the only way the victims of titanic could be left in peace is to oblitterate the wreckage so there is nothing of interest left for wealthy voyeur playbouts to be snooping at and getting themselves in trouble.

I don't understand this "I think the only way the victims of titanic could be left in peace" idea. They're dead. Everyone who ever knew them is dead. What do they care now who visits?
Titanic was absolutely notable aside from the story surrounding it btw - it was the biggest ship afloat when it launched, and probably the most opulent.
And I'd have no interest in visiting Titanic (well, not where it currently is anyway).
If you watch the Hunt for Red October, you'll see the U.S. Navy dropping the sonar bouys into the ocean from planes. they send pings out and when/if they receive a ping back, they can calculate how far away whatever returned/reflected the ping back to them is... then if you have 3 or more of these sonar boys, and they all detect something, they can calculate with a high degree of accuracy where the object is...
So let's ensure maritime mass grave sites are respected by obliterating them?
Obliterating?
As in send down depth charges to blow up the wreckage so that it'll no longer be attracting voyeurs.
But they say that in another 50 or 60 years or whatever that the wreck will have almost totally disintegrated anyway. There are bacteria down there that eat away at the steel.
Well wrecks are extremely good for sea life in shallow waters anyway, to the point where old military ships are intentionally sank in certain areas to help ecosystems. Blowing these things up to stop voyeurs seems pretty pointless and impossible, since ships of note are far too big to actually destroy beyond recognition anyway.
The exhibitions they have with stuff taken from the wrecks is morbid too, you can buy actual coal they took up from the Titanic for $36.95...
There is nothing wrong with visiting graves.
Not 100% comparable but the Titanic was discovered using an unmanned towed camera sled which can operate down to 6000m and has an umbilical for power, data and control. Investigation of the wreck was then carried out using a fully independent submersible (which, in turn had small unmanned camera subs on umbilicals for exploring into the wreck).
Tethering for an exploration submersible is probably a retrograde step and could increase the risk of an accident in the first place.
The feasibility of tethering down that deep with swift currents etc is very much in question but I don’t like the alternative as it’s turn out to be.
Yes, in years to come there’ll be a mock-up where you can sit inside and experience a virtual descent in darkness and catch a murky glimpse of Titanic, for €100 a go.
