00:00The poor Titanic has no respite. After being destroyed for the first time, it undergoes its second collapse, on the seabed.

00:09Experts think that there will be nothing left of it by 2050.

00:13Recently, scientists have organized new expeditions to the Titanic. These exciting trips took place in 2021 and 2022.

00:22They studied the archaeology of the wreck, mapped it and took some 8,000 photos.

00:27They discovered that the oceanic forces consumed the Titanic much more quickly than many other ships.

00:33Some boats have been sinking at the bottom of the seas for centuries and are doing quite well. Why?

00:39First of all, like any other wreck, the Titanic slowly succumbs to pressure and salty water.

00:45Parts of the promenade bridge have already collapsed. Captain Smith's bathtub is filled with debris, the roof has fallen on it.

00:53The door of the officers' quarters has also begun to disintegrate. The bow still holds up well, buried under 18 meters of mud, as it did 25 years ago.

01:02But one day, it will also know an ineluctable fate.

01:06Some structures of the ship could last much longer, perhaps hundreds of years. For example, the boilers and alternative engines.

01:14But lighter elements, such as ramparts and wood, are doomed.

01:18The starved microbes are one of the main causes of the accelerated degradation of the ship. The Titanic is being stored.

01:26It turns out that the Titanic has its own type of bacteria, called Halomonas titanicae. Yes, it bears the name of the ship.

01:34This bacteria was discovered in the rusticles. This is how these stalactite-shaped rust formations are called.

01:40They tingle the hull of the Titanic. Scientists discovered them for the first time in 1920 during an expedition on the Paves.

01:48These little animals slowly rub the steel. They adhere to the surface, which causes the formation of button-shaped rust mounds.

01:55These mounds cover the entire Pave, and the porous rusticles then dissolve into a fine powder. It's as if they were trying to reduce the ship to dust.

02:04You add to this the immense pressure, the very low temperatures, and the salt, and you get an extremely rapid decomposition.

02:11But bacteria are not the only problem. Two main factors determine the lifespan of a wreck after its shipwreck.

02:18The first is oxygen, or rather, lack of oxygen. As you go down into the ocean, oxygen levels decrease significantly.

02:27Surprisingly, this really slows down the decomposition process. Oxygen is very important for life, and if there is none, many organisms simply do not get by.

02:38In addition, some chemical decomposition processes, such as iron rust, require oxygen.

02:44This is why ships that have sunk into shallow waters and rich in oxygen generally deteriorate much faster.

02:51The Titanic rested in an oxygen-deficient zone, which, at first, allowed it to better preserve its structure.

02:58But it then adopted its own bacteria, like a pet. And it turned out that this bacteria loves its oxygen-deficient conditions. Who would have thought?

03:07There is an interesting reason for this.

03:11Throughout history, most ships, whether on the surface or underwater, have been built of wood.

03:17Things changed in the 1840s, with the Industrial Revolution.

03:22Metal ships were made, mainly iron and steel, like the Titanic.

03:28Finally, they began to become larger and more solid.

03:32In addition to the Titanic, there was the Lusitania and other luxury ships.

03:36At first glance, metal ships are much better. They lasted longer than wooden ships, even underwater.

03:43Even if they rust, they last dozens of times longer.

03:47Animals and microbes enjoy the decomposition of wood.

03:50As soon as a wooden ship is sunk, the microbes begin to decompose it.

03:54What caused the most problems was the madmen.

03:57They are called shipworms in English, because they dig holes in wooden ships to feed on them.

04:02These worms can completely demolish a wreck in just two years.

04:07Of course, this is not a problem for metal ships, because steel and iron are very difficult to digest.

04:14So they last a while if they sink in temperate and shallow waters.

04:18But in cold and deep waters, it's another pair of sleeves.

04:22A wooden ship that sank very far under the surface will do relatively well because there are no creatures to devour it.

04:30There are at least 60 ancient wrecks in the Black Sea, some of which date back to Ancient Greece.

04:35And all is well for them. The engravings on their floors are still readable.

04:39One of them is a Greek merchant ship dating back more than 2,000 years.

04:44The bow, the bow straps and even the contents of the hull are perfectly preserved.

04:50It is now known as the oldest intact wreck.

04:54But in cold and deep waters, microbes, like those that eat our Titanic, feed on iron.

05:01Usually, they find this iron in geological vents at the bottom of the seas, underwater volcanoes, etc.

05:08But today, they feed on it thanks to humans.

05:14All this brings us to the second crucial factor of disintegration, the materials.

05:19Organic materials are the big losers, especially in the high seas.

05:23Not only because of the microbes, but also because they are much more fragile than ceramic, glass, stone or metal materials.

05:31For organic matter to survive, it is often preferable to bury it.

05:36Indeed, the fossils buried underground are well protected from oxygen and bacteria that contribute the most to decomposition.

05:42Take, for example, the Mary Rose, a Tudor ship that sank in the 16th century near England.

05:49Many of its structures and wooden objects were preserved thanks to the mud that covers them.

05:54Or the SS Central America.

05:56This ship sank off the coast of Northern California in 1857.

06:01It contained many treasures.

06:03In 1991, a couple of divers made an extraordinary discovery.

06:09A work pants from this ship.

06:12The pants are 150 years old, but it survived because it was in a leather box, buried and sealed.

06:18So that neither oxygen nor microbes could reach it.

06:21The pants owner, John Demand, survived the shipwreck.

06:25But all his equipment sank.

06:27The rediscovered pants raised more than $100,000 during a auction in 2022.

06:34Even if the Titanic disintegrates completely, maybe by 2050, it will know an interesting fate.

06:42As we said, these wrecks rest at insensitive depths, between 2,900 and 6,000 meters.

06:48This is where the Abyssal Plain is located.

06:50One of the flattest and most depressing places on the planet.

06:54An infinite extension of muddy seabed.

06:57From time to time, you will find stones and rocky blocks there.

07:01They were brought there by drifting glaciers.

07:04The glaciers turn into icebergs.

07:06This is why the Titanic sank.

07:08And the icebergs, by melting, drop their stones on the seabed.

07:12This kind of place is scary for us, humans.

07:15But for the small marine fauna, it's great.

07:18This vast quiet area is home to whistling worms and other tiny creatures.

07:23And what they prefer, are shipwrecks.

07:26The Titanic will become their home.

07:28An artificial reef.

07:30Even after its disintegration, its structure will constitute a substrate for marine life.

07:35Like a shard.

07:37These artificial reefs create small pockets of life.

07:40Unexpected in the underwater deserts.

07:42And coral loves to develop on wrecks.

07:45Over time, it creates an ideal environment for some creatures.

07:49The Titanic is already transforming into a very lively place.

07:52Filled with corals and small animals.

07:55The images show us an amazing biological diversity.

07:58Shrimp.

07:59Seagulls.

08:00And also these amazing grenadiers who travel the site in all directions.

08:04As a reef, the Titanic will continue to thrive for centuries.

08:09Researchers are impatient to be able to go to the Titanic in the future.

08:13They will use advanced technologies.

08:16Sonar and laser scanning.

08:18To study the wreck and take high quality photos.

08:21In order to better understand the state of the famous ship.

08:23They are also curious to know the conditions of coral growth on wrecks.

08:27They generally develop on natural supports.

08:31All this will be useful for marine biology and the naval industry.
