00:00You are on the front of the ship when a black and gray mass appears to the horizon.
00:06In a manner of a nightmare or a horror movie, a strange brume approche slowly from the building.
00:12It seems without fin, impossible to distinguish where it starts and ends.
00:16In a rien of time, the ship is minuscule, perdu in a mer of glass.
00:20It is then that you understand, it is not the brouillard, but an iceberg,
00:24and your ship is on the point of knowing the same sort that the Titanic.
00:28This kind of scene is quite plausible,
00:31because the biggest iceberg in the world, called A-23A,
00:35is removed after being left prison for several months
00:38of a gigantic sea turbine.
00:40It is the second time, in a few years only,
00:43that this glass of glass comes to liberate.
00:46The first comes to 2023.
00:48After being left out on the ground for not less than 37 years,
00:52the iceberg was made to err on the grays of the currents.
00:55It covers an equivalent to three times that of New York.
00:58Its weight is also about 1000 milliards of tons.
01:01This glass glass is detached for the first time
01:04from the glacier plate of Filchner, in Antarctica, in 1986.
01:09But instead of deriving, it was immobilized on the high fonds,
01:12at a weak distance from its point of rupture.
01:15It has thus fonded much more slowly than the majority of icebergs.
01:19It is in December 2023 that A-23A is finally released for the good,
01:23entamant a lento derive near the Antarctic.
01:25However, its course has quickly been interrupted.
01:28It is found to be close, not far away from the East,
01:31from the East,
01:32in what we call a column of Taylor.
01:35A gigantic turbine,
01:37which is formed when the currents currents
01:40circulate around a marine marine mountain.
01:42At a moment,
01:43the iceberg turns on himself
01:45at about 15 degrees per day
01:46in the inverse of the aiguilles of a moon.
01:48But since the 13th of December 2024,
01:51A-23A is coming out of this column of Taylor
01:54and takes place again.
01:56The scientists observe attentivement
01:58their journey.
01:59Curious to know
02:00if it is the same trajectory
02:02that other icebergs
02:03or if it follows a new route inédit.
02:05The icebergs also gigantic
02:07that the A-23A
02:09liberate nutrients
02:10in the environment
02:11when they are sinking.
02:12This phenomenon
02:13can in fact create
02:14the living areas
02:15in the oceanic
02:16habitually desert.
02:17However,
02:18there is still a lot
02:19to understand
02:20the way
02:21the characteristics
02:22such as the size,
02:23the shape
02:24or the origin
02:25of an iceberg
02:26influence this process.
02:27To learn more,
02:28the researchers
02:29have begun to collect
02:30some water particles
02:31from the zones
02:32that A-23A
02:33are susceptible
02:34to traverse.
02:35And they will continue
02:36to raise it all along
02:37their derives
02:38in hoping
02:39that this will allow us
02:40to better understand
02:41the impact
02:42of massive icebergs
02:43on the marine ecosystems
02:44around.
02:45In fact,
02:46the glacier
02:47to which our colonel
02:48belonged
02:49is an ancient
02:50remarkable
02:51literally millenniaire.
02:52In Antarctic,
02:53the most ancient
02:54glace
02:55could date
02:56of about 1 million years.
02:57In Groenland,
02:58she reached
02:59more than 100.000 years.
03:00In Alaska,
03:01the most ancient
03:02glace
03:03never recovered
03:04discovered
03:05in a basin
03:06between the
03:07Mount Bona
03:08and Churchill
03:09has about 30.000 years.
03:10A bambin
03:11next to the others.
03:12In a glacier
03:14typical of Alaska
03:15in Alaska,
03:16it takes about
03:17100 years
03:18to make the glacier
03:19recently formed
03:20across the entire
03:21of the glacier.
03:22The glacier
03:23Bering,
03:24the most vast
03:25of this state,
03:26with its 225 km
03:27long,
03:28its glacier
03:29has been able
03:30to traverse
03:31in less than 400 years.
03:32This shows
03:33the movement
03:34constant
03:35of a glacier
03:36of the Atlantic
03:37which relie
03:38the Arctic
03:39to Terre-Neuve.
03:40If you dream
03:41to see a multitude
03:42of icebergs,
03:43it is there
03:44that you have to make.
03:45Every year,
03:46many blocks of glass
03:47across this region,
03:48the majority from Groenland.
03:49In winter
03:50and summer,
03:51large fragments
03:52of glacier
03:53get out
03:54by the north-sud
03:55currents
03:56across the Baie
03:57of Baffin
03:58to reach the
03:59Mer of Labrador
04:00where they end up
04:01from.
04:02Some also
04:03come from
04:04Canadian
04:05to reach the Mer
04:06of Labrador
04:07and along the coast
04:08east and west
04:09of Terre-Neuve.
04:10These huge blocks
04:11of glass
04:12are also very ancient,
04:13dating from around
04:1410.000 years.
04:15Each year,
04:16between 400
04:17and 800 icebergs
04:18from average
04:19across the Allée
04:20of the Icebergs.
04:21The speed of their
04:22derives depends
04:23of their volume,
04:24their shape,
04:25their currents,
04:26their waves
04:27and the wind.
04:28But the average speed
04:29is less than 600 m
04:30per hour.
04:31There are six types
04:32of icebergs
04:33rocks

04:55icebergs

04:59All these are impressive. Let us know in the comments which is your favorite.
05:03As soon as these icebergs arrive towards the south, the most hot water increases their fonte,
05:09which makes them imprevisibles, sometimes even dangerous.
05:12Today, the satellites follow the icebergs of size large and medium to avoid accidents.
05:17But the most reduced is a danger for the small embarcations.
05:21In 2018, a iceberg has made the big title
05:24when it is approached in a habit of the village of Ferryland at Terre-Neuve.
05:28The photos montrant this gigantic iceberg dominant the houses of the village have turned the web.
05:34It is found in 100 meters of water, a very deep zone for its size.
05:40And now, I'm going to take you to a amazing journey to assist to something amazing and a great tragedy.
05:48His existence even has led to one of the biggest catastrophes of history.
05:52Look, a huge block of glass is detached from the south-west of Groenland.
05:57He is composed of tombs, a more than 1000 miles,
06:01at the time when the mammoths were still on Earth.
06:04The enormous iceberg begins its long period.
06:07He weighs more than 520 meters long and weighs 75 millions of tons.
06:12Despite its size, he remains relatively peaceful
06:15and takes away from the ships as well as the main waves
06:18as well as the maritime coast of its glacier natal.
06:21However, he begins to deriver towards the south,
06:23even further than most of the icebergs.
06:25In general,
06:27the blocks like this will be found before coming to the seas too cold.
06:32Among the 15000 to 3000 icebergs
06:34which are detached from the glacier and the Groenland every year,
06:37only 1% of them come to the Atlantic.
06:40The exceptional trajectory of this iceberg,
06:43which reaches more than 8000 kilometers
06:45on the south of the Arctic Arctic in April,
06:47the rends truly unique.
06:49Even after several months of fonte,
06:51this block of glass is an impressive size.
06:54It weighs about 1,5 million tons,
06:56so close to two times the weight of the golden gate.
06:59On the top of the sea,
07:01its part visible is up to more than 30 meters.
07:03But,
07:04like most icebergs,
07:06the majority of its mass,
07:07about 90%,
07:09are under the surface.
07:11The story of this iceberg
07:12takes a tragic turn on the 14th of 1912,
07:15when,
07:16when,
07:17what,
07:18it is,
07:19the Titanic croise the Titanic.
07:20The ship is at about 600 kilometers
07:23in the Atlantic Atlantic Atlantic,
07:25when the iceberg seems to come from nowhere.
07:27Why do they not see it before the collision?
07:31Why do they not see it before?
07:33Excellent question.
07:35Most people imagine the icebergs
07:37as a large glass glass of glass,
07:39often covered with snow.
07:41However,
07:43in reality,
07:44the icebergs exist in a multitude of colors.
07:46Some have some rayures,
07:48some patterns,
07:49or even the tourbillons,
07:50similar to the bonbons.
07:52And it is even possible
07:53that they are black.
07:54A iceberg can become black
07:56and white.
07:57When the glass is extremely pure,
07:59without bubbles
08:00nor fissures,
08:01they absorb all the light
08:02instead of the renvoyer,
08:03which gives them
08:04an appearance sombre.
08:05Another possibility
08:07is that a volcanic eruption
08:08will recouvre
08:09a glacier of sand.
08:10If a piece of this glacier
08:11will be detached,
08:12it will be a black.
08:14The researchers
08:15are still not certain
08:16of the reason
08:17why the Titanic
08:18is still sombre.
08:19Or even if it was really the case.
08:21It is really the case.
08:22Cependant,
08:23the vigil has affirmed
08:24that it was black.
08:25Another matelot
08:26the describes
08:27as gris
08:28or gris foncé.
08:29The hypothesis
08:30suggests that this block
08:31could be a iceberg
08:32noir,
08:33formed when the
08:34part of the top
08:35falls,
08:36which is causing
08:37the iceberg.
08:38If the part of the top
08:39is enough lisse
08:40to absorb the light,
08:41it appears
08:42also sombre.
08:43However,
08:44even if the iceberg
08:45was not really black,
08:46the night
08:47has certainly
08:48complicated.
08:49The icebergs
08:50don't reflect
08:51the light,
08:52especially when they
08:53are irregular
08:54or vertical.
08:55They then fall
08:56into the sombre
08:57and scintillant.
08:58Without a radar,
08:59it is extremely
09:00difficult to see
09:01a iceberg
09:02the night,
09:03which explains
09:04probably why
09:05the Titanic
09:06did not see it
09:07as well.
