Someone would have to be actually listening when the implosion happened...but whether or not it would be heard would depend on salinity and temperature conditions (as corsair alluded to above). Strong haloclines or thermoclines can prevent sound from reaching different depths, and can trap sound in channels (sound channels).

The sound of the vessel breaking up would be very distinctive, and would not be mistaken (most likely) for biologic sources (and I've heard them all!) by a novice listener, and certainly not by a trained listener.

The key would be actually listening at the time of the event with quality hydrophones (at appropriate depths) and quality processing equipment-which I have no knowledge of whether ships in the area possess.

Just my (somewhat knowledgable!) opinion!

An implosion at that depth would be a far more preferable death than slowly suffocating. Most of us won't be so lucky to go that quickly.

Like smashing an ant on concrete with a sledge hammer.

Yes, I really can't think of a much worse death than suffocating...in the dark...in a cramped cabin enduring the stench of strangers.

Debris Field Found During Search For Titanic
Submersible: Coast Guard

Story by Nina Golgowski • 1h ago

A debris field has been discovered during a search for a missing submersible that was carrying five people near the Titanic wreckage, the U.S. Coast Guard said Thursday.

The discovery was made by a remotely operated vehicle searching the area, which is being evaluated by experts within the unified command. That group reportedly consists of the U.S. Coast Guard, U.S. Navy, Canadian Coast Guard and OceanGate Expeditions.

A press briefing will be held at 3 p.m. EST to discuss the findings from the Horizon Arctic’s remotely operated vehicle, the Coast Guard said.

This is a developing story. Check back for updates.

The landing frame and rear cover of the missing Titan submersible have been discovered on the ocean floor, according to experts involved in the search, who say it points to the vessel suffering a 'catastrophic implosion' that will have claimed all five of the lives on board.

Compared to all but a few potential outcomes, this is honestly the best one this Thursday morning. It was almost assuredly instantaneous. One only hopes there were no signs that hull failure was even a risk, let alone imminent, that they may have died not only in a blink but with no anxiety or inkling that it was coming.

They would not have felt a thing, and nor aware there was a problem.

OceanGate likes to tout how they have sensors around the hull of the craft to detect any impending problems. At these depths, there's no warnings.

So this mapping company is breathlessly holding themselves back, while blaming the Coast Guard for not allowing them to play on the field?
Sounds more like a pathetic PR ploy, not to mention they're a mapping/survey company, which means they use side-scan sonar, a VERY laborious and lengthy process. While their equipment is useful, they're coming across as posturing pricks insisting they get involved

from CNN:

"The University of Washington reiterated Wednesday that they were not involved in the design, engineering or testing of the Titan submersible, despite assertions that they were, according to a 2021 court filing by OceanGate. CNN reached out to OceanGate for comment.

Separately, Boeing also released a statement saying they were not a partner on the Titan and they did not design or build the submersible, despite a 2021 press release from OceanGate listing the company as a "partner." OceanGate told CNN it was unable to provide additional information about its relationship with Boeing."

"An industry leader said OceanGate Expeditions strayed from industry norms by declining a voluntary, rigorous safety review of Titan. “There are 10 submarines in the world that can go 12,000 feet and deeper,” said Will Kohnen of the Marine Technology Society. “All of them are certified except the Oceangate submersible.”

It may have been already mentioned, but vessels like this can be weakened by repeated excursions to deep depth. So a vessel could hold up for a number of dives, but then develop a failure point

This was my assumption. Especially after learning how the craft was constructed, I was pretty sure a breech in the hull ended that trip real quick.

Par for the course.

So who actually designed and engineered this thing?

Not surprising that U of W and Boeing want to distance themselves as far as possible from the design of this sub.

Fun fact: the debris field of the sub was discovered by 50-year-old white guys. Go figure.

U Dub's Applied Physics Lab was apart of the conception and design process.
Titanium Fabrication Corp made the titanium hull cylinder.
Spencer Composites made/weaved the original carbon fiber hull layers.
It's been alleged that either Electroimpact and/or Janicki Industries had made a carbon fiber hull layer replacing the Spencer Composites layer.

Boeing's facilities or, employees may have been involved at some point but, no indication the company was involved in design, development or, construction. OceanGate CEO sounds like the type of guy that wants as many big-name brands attached to a project, regardless of their contribution or involvement.

The parts of Titan which the Coast Guard believe they've found. “Landing frame” and “rear cover.”

It sounds like this is done.

quote:
OceanGate Expeditions has confirmed the deaths of the five men on the missing Titan submersible, parts of which were discovered today on the ocean floor 500 meters from the bow of the famous ship they died trying to see.

The landing frame and rear cover of the missing submersible were discovered today by a remote operated submarine in a devastating blow to any hope that the men may still be found alive.

It would mean the sub suffered a crack and imploded under the underwater pressure, instantly killing all five men on board.

from CNN:

OceanGate said Thursday that it believes the passengers of the Titanic-bound submersible have “sadly been lost,” according to a statement from the company.

“We now believe that our CEO Stockton Rush, Shahzada Dawood and his son Suleman Dawood, Hamish Harding, and Paul-Henri Nargeolet, have sadly been lost,” the company said in a statement.

The debris discovered within the search area of the missing Titanic submersible has been assessed to be from the external body of the sub, according to a memo reviewed by CNN.

The search for the crew capsule of the Titan vessel continues, the memo says.

The debris was located on the ocean floor, roughly 500 meters (about a third of a mile) off of the bow of the Titanic, and it was found around 8:55 a.m. ET.

It was discovered by a remotely operated vehicle that was searching the seafloor, according to the US Coast Guard.
