Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:02,067 --> 00:00:04,027
Could a Nazi shipwreck
2
00:00:04,067 --> 00:00:06,427
lying at the bottom
of the Baltic Sea
3
00:00:06,467 --> 00:00:11,897
finally reveal the location of one of
the world's greatest lost treasures?
4
00:00:11,933 --> 00:00:14,733
We start thinking, "My God!
Maybe it's something important."
5
00:00:15,700 --> 00:00:17,500
Is there an unknown force
6
00:00:17,533 --> 00:00:21,303
capable of snapping ships
clean in half
7
00:00:21,333 --> 00:00:24,173
and sinking them
with no warning?
8
00:00:24,200 --> 00:00:27,100
How can a ship just break
into two pieces?
9
00:00:28,367 --> 00:00:30,627
And who or what is responsible
10
00:00:30,667 --> 00:00:34,627
for a bizarre series
of sea lion mutilations...
11
00:00:35,667 --> 00:00:38,627
in the waters around Vancouver?
12
00:00:38,667 --> 00:00:42,767
It was something, in my
opinion, that did this deliberately.
13
00:00:45,733 --> 00:00:50,203
The underwater
realm is another dimension.
14
00:00:50,233 --> 00:00:53,533
It's a physically hostile place
15
00:00:53,567 --> 00:00:58,567
where dreams of promise
can sink into darkness.
16
00:01:00,367 --> 00:01:04,067
I'm Jeremy Wade
and I'm searching the world
17
00:01:04,100 --> 00:01:05,670
to bring you the most iconic
18
00:01:05,700 --> 00:01:10,770
and baffling underwater
mysteries known to science.
19
00:01:10,800 --> 00:01:16,870
The vast majority of our ocean is
unobserved, unmapped, and unexplored.
20
00:01:16,900 --> 00:01:21,800
It's a dangerous
frontier that swallows evidence.
21
00:01:21,833 --> 00:01:24,273
You have nowhere to run.
22
00:01:24,300 --> 00:01:30,500
Where unknown is
normal and understanding is rare.
23
00:01:46,467 --> 00:01:51,827
Tales of lost treasure have captivated
our imaginations for centuries,
24
00:01:51,867 --> 00:01:54,397
but few of these stories
are as puzzling
25
00:01:54,433 --> 00:01:57,833
as the disappearance
of the Amber Room.
26
00:01:59,500 --> 00:02:01,470
It's the height of World War II
27
00:02:01,500 --> 00:02:06,330
and the Nazis steal a priceless
masterpiece from the Soviet Union,
28
00:02:06,367 --> 00:02:11,797
a dazzling room made of amber,
gemstones and gold.
29
00:02:14,267 --> 00:02:17,067
When the brutal conflict
comes to an end,
30
00:02:17,067 --> 00:02:21,497
all traces of this magnificent
treasure are gone.
31
00:02:21,533 --> 00:02:25,103
But now a fresh investigation
by a team of divers
32
00:02:25,133 --> 00:02:28,933
suggests that the Amber Room's
final resting place
33
00:02:28,967 --> 00:02:32,497
might be deep beneath
the Baltic Sea.
34
00:02:39,700 --> 00:02:42,530
June 22, 1941,
35
00:02:42,567 --> 00:02:47,167
Adolf Hitler's invasion of
the Soviet Union begins.
36
00:02:51,067 --> 00:02:52,767
As they advance,
37
00:02:52,800 --> 00:02:58,870
the Nazis pillage gold, art
and other valuable treasure.
38
00:02:58,900 --> 00:03:02,630
High on Hitler's wish list
is the Amber Room
39
00:03:02,667 --> 00:03:07,197
located in Leningrad's
Catherine Palace.
40
00:03:07,233 --> 00:03:10,303
The Amber Room is often dubbed
the Eighth Wonder of the World
41
00:03:10,333 --> 00:03:13,073
such was its absolute
magnificence.
42
00:03:16,467 --> 00:03:18,427
Made from huge panels
43
00:03:18,467 --> 00:03:22,067
containing over six tons
of prehistoric amber,
44
00:03:22,100 --> 00:03:25,470
gold and precious gemstones,
45
00:03:25,500 --> 00:03:29,500
this extravagant chamber
is the envy of the world
46
00:03:29,533 --> 00:03:33,203
and is estimated to be worth
up to half a billion dollars
47
00:03:33,233 --> 00:03:34,703
in today's money.
48
00:03:36,100 --> 00:03:38,100
Once captured by the Nazis,
49
00:03:38,133 --> 00:03:42,073
the exquisite amber panels
are ripped from the walls,
50
00:03:42,067 --> 00:03:44,727
placed into individual
wooden crates
51
00:03:44,767 --> 00:03:48,067
and transported over land
from Leningrad
52
00:03:48,067 --> 00:03:50,527
to the port city of Konigsberg.
53
00:03:54,667 --> 00:03:57,267
The tide of war turns
54
00:03:57,300 --> 00:04:00,930
and by 1945,
Konigsberg is under siege
55
00:04:00,967 --> 00:04:03,367
and surrounded by the Soviets.
56
00:04:06,567 --> 00:04:08,527
What happens to the Amber Room
57
00:04:08,567 --> 00:04:10,967
during the onslaught
is unknown...
58
00:04:12,767 --> 00:04:17,297
but when Soviet troops
finally capture the city,
59
00:04:17,333 --> 00:04:20,673
all signs of it have vanished.
60
00:04:22,433 --> 00:04:26,373
She disappeared and nobody
knows what's happened.
61
00:04:27,767 --> 00:04:29,797
Where's the Amber Room?
62
00:04:29,833 --> 00:04:32,803
That's the thing.
We don't know. It's a mystery.
63
00:04:34,800 --> 00:04:37,670
Many people
believe this priceless treasure
64
00:04:37,700 --> 00:04:39,930
was destroyed
during the fighting...
65
00:04:41,567 --> 00:04:44,867
but could the Amber Room
have survived?
66
00:04:45,933 --> 00:04:47,773
Under the orders
of Joseph Stalin
67
00:04:47,800 --> 00:04:53,870
in 1946 the KGB launches
a secret investigation.
68
00:04:53,900 --> 00:04:57,900
The Amber Room is one of the
great cultural treasures of Russia.
69
00:04:57,933 --> 00:05:01,103
The Germans stole it,
the Russians wanted it back.
70
00:05:02,433 --> 00:05:05,433
And they uncover a vital clue.
71
00:05:07,867 --> 00:05:10,367
A set of partially
burned letters
72
00:05:10,400 --> 00:05:13,600
emerge from the smoldering
ruins of Konigsberg.
73
00:05:14,933 --> 00:05:17,803
Dated January 12, 1945,
74
00:05:17,833 --> 00:05:21,573
they order the immediate
evacuation of the treasure.
75
00:05:21,600 --> 00:05:25,330
There's a very strong chance that the Amber
Room could have survived the Second World War.
76
00:05:26,967 --> 00:05:30,667
The search
shifts to mainland Europe,
77
00:05:30,700 --> 00:05:34,770
deep into abandoned bunkers,
caves, and mines.
78
00:05:36,900 --> 00:05:41,200
But have we been looking for this
lost treasure in the wrong place?
79
00:05:42,067 --> 00:05:43,467
There have been numerous
attempts
80
00:05:43,500 --> 00:05:47,500
to try and find the Amber Room
on land, but very few underwater.
81
00:05:49,300 --> 00:05:51,770
The key thing here
is to remember exactly
82
00:05:51,800 --> 00:05:55,130
where the Amber Room was
being stored. It was in Konigsberg.
83
00:05:55,167 --> 00:05:57,367
The only way to leave
Konigsberg at this point in time
84
00:05:57,400 --> 00:06:02,570
was on a vessel
going through the Baltic Sea.
85
00:06:02,600 --> 00:06:06,900
What if the Amber Room never made it back
to Germany? What if it was sunk en route?
86
00:06:08,500 --> 00:06:12,830
Could this priceless
treasure be hidden beneath the waves
87
00:06:12,867 --> 00:06:17,127
waiting to be found on one of
the Baltic Seas' many shipwrecks?
88
00:06:20,867 --> 00:06:23,467
To save the soldiers
and civilians
89
00:06:23,500 --> 00:06:27,130
trapped by the advancing
Soviets...
90
00:06:27,167 --> 00:06:33,897
the Germans launch a huge rescue
mission, codenamed Operation Hannibal.
91
00:06:33,933 --> 00:06:38,173
It was the biggest maritime
evacuation ever.
92
00:06:39,467 --> 00:06:42,967
Hundreds of
ships crisscrossed the Baltic,
93
00:06:43,067 --> 00:06:45,827
running a gauntlet
of brutal weather
94
00:06:45,867 --> 00:06:49,627
and Soviet submarine
and air attacks.
95
00:06:50,933 --> 00:06:53,933
The Amber Room is an
irreplaceable artifact...
96
00:06:56,367 --> 00:07:01,367
and very few ships can be trusted
to carry it on this perilous journey.
97
00:07:04,433 --> 00:07:07,873
One of them
is the Wilhelm Gustloff.
98
00:07:07,900 --> 00:07:11,600
It was the pride of
the Nazi Merchant Fleet.
99
00:07:11,633 --> 00:07:14,533
It was their big status
cruise line.
100
00:07:16,500 --> 00:07:19,530
Hitler's very
own version of the Titanic,
101
00:07:19,567 --> 00:07:23,527
the Wilhelm Gustloff was
designed to take Nazi passengers
102
00:07:23,567 --> 00:07:25,527
on luxury pleasure cruises.
103
00:07:28,100 --> 00:07:30,130
But with Germany losing the war,
104
00:07:30,167 --> 00:07:33,597
the ocean liner is sent
to help with the evacuation.
105
00:07:35,067 --> 00:07:37,927
As German refugees
pour on board,
106
00:07:37,967 --> 00:07:41,197
another cargo
arrives at the dock.
107
00:07:41,233 --> 00:07:45,333
It also picks up crates
which are under armed guard.
108
00:07:45,367 --> 00:07:46,767
And you have to ask yourself,
109
00:07:46,800 --> 00:07:48,630
why would you need armed guards
110
00:07:48,667 --> 00:07:52,767
if there isn't something
incredibly valuable in those crates?
111
00:07:52,800 --> 00:07:56,900
A rumor spreads and some
of the passengers on the ship suspect
112
00:07:56,933 --> 00:07:58,933
they hold the Amber Room.
113
00:08:01,433 --> 00:08:07,373
The Wilhelm Gustloff departs
in a blistering winter snowstorm.
114
00:08:07,400 --> 00:08:11,470
They do not expect any Russian
attack during this terrible weather.
115
00:08:14,400 --> 00:08:19,300
But the defenseless
cruise liner isn't alone.
116
00:08:19,333 --> 00:08:24,303
It's torpedoed by a Soviet
Submarine and it sinks very quickly.
117
00:08:27,867 --> 00:08:31,527
It was the beginning of
a huge, huge, disaster.
118
00:08:34,400 --> 00:08:38,330
Most of the lifeboats
are frozen solid to their fittings...
119
00:08:40,167 --> 00:08:44,897
triggering a calamity
of catastrophic proportions.
120
00:08:44,933 --> 00:08:50,073
This proves to be the greatest
loss of life ever in maritime history.
121
00:08:50,067 --> 00:08:53,897
9,500 people lost their lives.
122
00:09:02,967 --> 00:09:05,167
The wreck
of the Wilhelm Gustloff
123
00:09:05,200 --> 00:09:10,070
is the site of one of the greatest
tragedies of World War II...
124
00:09:10,067 --> 00:09:14,897
but could it also be the final
resting place of the Amber Room?
125
00:09:14,933 --> 00:09:17,773
The mission to find out
begins in the 1960s
126
00:09:17,800 --> 00:09:21,800
when Polish divers pinpoint
the location of the wreck.
127
00:09:23,733 --> 00:09:27,203
But as the outline of the ship
looms in front of them
128
00:09:27,233 --> 00:09:29,833
something isn't right.
129
00:09:29,867 --> 00:09:33,067
The strangest thing was that
this supposedly unknown wreck,
130
00:09:33,067 --> 00:09:38,627
this un-dived wreck had
had a lot of diving activity on it.
131
00:09:38,667 --> 00:09:42,867
It appeared that there was
much more post war damage to it.
132
00:09:42,900 --> 00:09:45,630
That the vessel
was destroyed, dynamited.
133
00:09:46,800 --> 00:09:49,800
If the Amber
Room was in the wreck,
134
00:09:49,833 --> 00:09:53,733
someone has beaten
the Polish divers to it.
135
00:10:07,033 --> 00:10:09,203
The disappearance
of the Amber Room
136
00:10:09,233 --> 00:10:13,003
is one of World War II's
greatest unsolved mysteries.
137
00:10:16,133 --> 00:10:18,303
But when divers narrow down
the search
138
00:10:18,333 --> 00:10:22,003
for this lost treasure to
a shipwreck in the Baltic Sea,
139
00:10:22,033 --> 00:10:25,273
they find someone has beaten
them to it.
140
00:10:29,700 --> 00:10:33,530
Who got to the Wilhelm Gustloff
first, and why did they ransack it?
141
00:10:34,567 --> 00:10:37,967
Suspicion falls on the Soviets.
142
00:10:38,000 --> 00:10:39,800
They are the navy in the region
143
00:10:39,833 --> 00:10:42,303
who had the technology
before the 1960s
144
00:10:42,333 --> 00:10:44,133
to actually do this kind
of investigation.
145
00:10:46,967 --> 00:10:51,667
Some people believe the
Russians knew the Amber Room was on board
146
00:10:51,700 --> 00:10:54,500
and launched a secret mission
to retrieve it.
147
00:10:55,533 --> 00:10:57,203
But if this was the case,
148
00:10:57,233 --> 00:11:02,533
why wouldn't they announce the rediscovery
of this beloved national treasure?
149
00:11:02,567 --> 00:11:05,297
Finding the Amber Room, if
they had managed to find it,
150
00:11:05,333 --> 00:11:08,833
would have been a tremendous
coup for the Soviet Union.
151
00:11:13,967 --> 00:11:17,527
A survivor's
testimony emerging decades later
152
00:11:17,567 --> 00:11:19,327
suggests they may have recovered
153
00:11:19,367 --> 00:11:22,167
a different kind
of Nazi treasure.
154
00:11:22,200 --> 00:11:25,870
Rudi Lange, who is a survivor
of the sinking of the ship
155
00:11:25,900 --> 00:11:28,070
and the radio operator,
156
00:11:28,067 --> 00:11:33,097
he came out in the 1980s and said,
"Nope, sorry. There was no Amber Room."
157
00:11:33,133 --> 00:11:35,233
He said that those crates
were being guarded
158
00:11:35,267 --> 00:11:37,727
because they were full of gold.
159
00:11:37,767 --> 00:11:43,097
Could the Amber Room have actually
been loaded into a different ship?
160
00:11:43,133 --> 00:11:45,433
Have we been hunting in
the wrong place all this time?
161
00:11:47,067 --> 00:11:52,527
Now, a team of Polish
researchers thinks this might be the case.
162
00:11:52,567 --> 00:11:58,067
I'm absolutely sure they do not
use Wilhelm Gustloff for this mission.
163
00:11:58,067 --> 00:12:00,427
Led by Tomasz Stachura,
164
00:12:00,467 --> 00:12:04,467
the team has identified
a standout alternative ship...
165
00:12:05,767 --> 00:12:07,897
the SS Karlsruhe.
166
00:12:09,167 --> 00:12:12,127
Records indicate this ship
was heavily laden
167
00:12:12,167 --> 00:12:15,897
with up to 360 tons of cargo.
168
00:12:15,933 --> 00:12:20,673
The Hannibal operation focused
on civilians and on the soldiers,
169
00:12:20,700 --> 00:12:23,970
so it was not very common
to take some cargo.
170
00:12:24,800 --> 00:12:26,930
And there's another key detail
171
00:12:26,967 --> 00:12:30,427
that makes the Karlsruhe
such an enticing candidate.
172
00:12:31,533 --> 00:12:36,503
It was the very, very, last
ship to leave Konigsberg
173
00:12:36,533 --> 00:12:39,303
before the
Soviet Forces arrived.
174
00:12:39,333 --> 00:12:42,473
So maybe in a panic, the
Germans placed the Amber Room,
175
00:12:42,500 --> 00:12:47,270
the gold, the gems,
the wealth, on this last ship.
176
00:12:47,300 --> 00:12:49,400
But the ship doesn't get far
177
00:12:49,433 --> 00:12:54,073
before it's spotted and attacked
by Soviet torpedo bombers.
178
00:12:55,833 --> 00:13:00,433
One aircraft bomb was sent
directly to the Karlsruhe
179
00:13:00,467 --> 00:13:03,097
and she sunk in three minutes.
180
00:13:05,267 --> 00:13:08,497
To find out what
the Karlsruhe was carrying,
181
00:13:08,533 --> 00:13:12,503
Tomasz and his team
first need to find its wreck.
182
00:13:12,533 --> 00:13:15,533
So hunting these ships
is not a quick process.
183
00:13:15,567 --> 00:13:18,097
It can take years.
184
00:13:18,133 --> 00:13:22,633
To aid the search, they
deploy a multi-beam echo sounder.
185
00:13:22,667 --> 00:13:25,727
They create more of
a three-dimensional image
186
00:13:25,767 --> 00:13:29,067
rather than a two-dimensional
image of what's on the seabed.
187
00:13:29,100 --> 00:13:31,270
It's a pretty fantastic
technology.
188
00:13:32,167 --> 00:13:34,067
We're very lucky
because we found the ship
189
00:13:34,100 --> 00:13:36,300
which was exactly the same size.
190
00:13:38,200 --> 00:13:40,130
Oh, my God!
Maybe we find Karlsruhe, yes?
191
00:13:42,367 --> 00:13:44,897
But the only way
for the team to know for sure
192
00:13:44,933 --> 00:13:47,603
is to dive the wreck themselves.
193
00:13:56,700 --> 00:14:00,330
We start to be absolutely sure
that we found Karlsruhe.
194
00:14:01,433 --> 00:14:03,773
We start to see
more and more details
195
00:14:03,800 --> 00:14:06,200
and our eyes
was bigger and bigger
196
00:14:06,233 --> 00:14:07,903
because we were
absolutely surprised.
197
00:14:09,100 --> 00:14:11,100
I am a diver of 40 years
198
00:14:11,133 --> 00:14:13,973
and I never ever saw
so many artifacts,
199
00:14:14,067 --> 00:14:18,967
so many chests, so many trucks
and motorcycles, guns...
200
00:14:21,300 --> 00:14:24,970
But are there any
signs of treasure on board?
201
00:14:25,067 --> 00:14:28,727
We were convinced that maybe
we can find one or two crates,
202
00:14:28,767 --> 00:14:33,967
but in one day we find
15 of them, one-five.
203
00:14:34,067 --> 00:14:36,297
It's seeing your presents
on Christmas morning.
204
00:14:37,433 --> 00:14:39,073
You don't know what's in them,
205
00:14:39,067 --> 00:14:41,127
but you notice something
cool ready to be unwrapped.
206
00:14:42,800 --> 00:14:45,900
Some of the
crates have spilled open
207
00:14:45,933 --> 00:14:48,973
giving a tantalizing glimpse
of their contents.
208
00:14:50,433 --> 00:14:52,503
The divers can see
what looks like
209
00:14:52,533 --> 00:14:56,503
the remains of canvas
and frames.
210
00:14:56,533 --> 00:15:01,273
If they've got very fine expensive
artwork on board the Karlsruhe
211
00:15:01,300 --> 00:15:04,070
then maybe also that could be
where the Amber Room is.
212
00:15:08,233 --> 00:15:14,333
Tomasz and his team plan to return to the
wreck of the SS Karlsruhe in the near future.
213
00:15:14,367 --> 00:15:16,827
With special permission
from the Polish government,
214
00:15:16,867 --> 00:15:21,067
they plan to salvage some
of the unopened crates.
215
00:15:21,067 --> 00:15:26,127
Their contents could reveal the
location the long-lost Amber Room
216
00:15:26,167 --> 00:15:30,727
and finally solve one of the
greatest mysteries of World War II.
217
00:15:39,667 --> 00:15:44,927
It's 2020 and the picturesque
beaches of Vancouver, Canada
218
00:15:44,967 --> 00:15:49,067
are about to become the setting
of a series of shocking discoveries.
219
00:15:50,333 --> 00:15:52,233
Over the course
of just a few months
220
00:15:52,267 --> 00:15:55,227
the remains of several
sea lions are found.
221
00:15:57,167 --> 00:16:01,367
All their heads are missing, removed
and separated from the rest of the body.
222
00:16:03,067 --> 00:16:07,667
Whatever is behind these
brutal attacks remains at large,
223
00:16:07,700 --> 00:16:11,200
but can the growing list
of suspects help solve
224
00:16:11,233 --> 00:16:14,103
these bizarre
animal mutilations?
225
00:16:15,633 --> 00:16:18,703
CTV News,
Vancouver Island report.
226
00:16:18,733 --> 00:16:20,073
Good evening.
Thanks for being here.
227
00:16:20,067 --> 00:16:21,667
A stellar sea lion has washed
up on a beach
228
00:16:21,700 --> 00:16:24,130
near Campbell River
without its head.
229
00:16:27,067 --> 00:16:29,897
The recent
reports of these grisly remains
230
00:16:29,933 --> 00:16:32,333
have gripped
the local population...
231
00:16:33,533 --> 00:16:36,403
but it isn't the first time
this has happened.
232
00:16:37,633 --> 00:16:39,273
Over the past ten years,
233
00:16:39,300 --> 00:16:43,230
countless other headless
sea lions have been found,
234
00:16:43,267 --> 00:16:46,867
dotted at different locations
around the Vancouver area.
235
00:16:49,067 --> 00:16:53,397
I cannot imagine the horror
that must have been experienced
236
00:16:53,433 --> 00:16:55,473
to come upon a sea lion
237
00:16:55,500 --> 00:16:58,130
that has been decapitated
on the beach.
238
00:16:59,533 --> 00:17:01,133
Are all these deaths connected?
239
00:17:01,167 --> 00:17:04,167
Is there a sea lion
serial killer on the loose?
240
00:17:05,333 --> 00:17:07,073
More worrying still,
241
00:17:07,067 --> 00:17:10,827
whatever is happening to these
sea lions appears to be spreading...
242
00:17:12,333 --> 00:17:17,603
and several seals have been
found in a similar state.
243
00:17:21,333 --> 00:17:24,873
I'm no stranger to unexplained
animal attacks...
244
00:17:26,900 --> 00:17:30,400
and I've spent many years on
the trail of unknown killers
245
00:17:30,433 --> 00:17:32,633
that lurk beneath the surface.
246
00:17:35,200 --> 00:17:39,300
So far, this case has
defied explanation.
247
00:17:39,333 --> 00:17:43,303
So I'm eager to hear
first-hand evidence for myself.
248
00:17:48,467 --> 00:17:51,967
In 2016, Vancouver resident,
Dave Stewart
249
00:17:52,067 --> 00:17:55,767
is walking his dog
on a local beach.
250
00:17:55,800 --> 00:17:59,430
I've come back to it. I
just found this on the beach.
251
00:18:02,767 --> 00:18:06,227
This seal's head's been
completely sheared off.
252
00:18:06,267 --> 00:18:08,097
Completely taken off.
253
00:18:09,133 --> 00:18:12,203
It's almost, it almost
looks fake in a way,
254
00:18:12,233 --> 00:18:16,433
but like this is a,
it's a real seal.
255
00:18:16,467 --> 00:18:18,467
I've never seen anything
like this ever.
256
00:18:19,600 --> 00:18:22,170
It was fresh, like sushi.
257
00:18:22,200 --> 00:18:26,830
Blood was coming out of the neck, dripping
out fresh. You can see this in the video.
258
00:18:26,867 --> 00:18:30,427
Dave, are there any signs of
what might have done this?
259
00:18:30,467 --> 00:18:32,967
You can see really nothing
disturbed in the sand,
260
00:18:33,067 --> 00:18:36,397
certainly not around the seal
itself of drag marks or anything.
261
00:18:36,433 --> 00:18:39,333
It was just sitting there
like it had been placed.
262
00:18:39,367 --> 00:18:41,167
And can you tell me any details
263
00:18:41,200 --> 00:18:43,530
about the wounds
around the neck?
264
00:18:43,567 --> 00:18:47,167
Though it was something, in my
opinion, that did this deliberately...
265
00:18:48,300 --> 00:18:50,930
not only is it, does it look
like it's been sliced,
266
00:18:50,967 --> 00:18:53,367
but in one section it looks
like it's been gnawed at.
267
00:18:54,833 --> 00:18:56,973
It seems the
heads of these animals
268
00:18:57,067 --> 00:18:59,497
are being intentionally targeted
269
00:18:59,533 --> 00:19:04,303
and taken by something...
or someone.
270
00:19:05,667 --> 00:19:08,167
Sea lions are huge animals.
271
00:19:08,200 --> 00:19:11,370
They can typically weigh
over 2,500 pounds
272
00:19:11,400 --> 00:19:14,900
and they can range
up to 12 feet in length.
273
00:19:14,933 --> 00:19:20,573
There aren't many other
animals which can take them out.
274
00:19:20,600 --> 00:19:24,070
But there is
one leading suspect.
275
00:19:24,067 --> 00:19:28,897
Some people think these attacks
could be the work of a known killer.
276
00:19:42,167 --> 00:19:44,967
When a series of
decapitated sea lions
277
00:19:45,067 --> 00:19:47,797
are found on the beaches
of Vancouver, Canada,
278
00:19:47,833 --> 00:19:52,103
the general public and law
enforcement are equally baffled.
279
00:19:52,133 --> 00:19:55,873
Could a ferocious predator
known to frequent these waters
280
00:19:55,900 --> 00:19:59,570
be responsible for these
strange animal deaths?
281
00:20:02,033 --> 00:20:04,333
Killer whales,
also known as orcas,
282
00:20:04,367 --> 00:20:07,327
frequently attack other
kinds of marine mammals.
283
00:20:09,533 --> 00:20:13,903
It's been documented
that they catch sea lions
284
00:20:13,933 --> 00:20:16,603
and sea lion pups
and play with them.
285
00:20:16,633 --> 00:20:19,833
Literally, it looks like they're
playing ocean volleyball.
286
00:20:21,367 --> 00:20:23,227
It could be forceful enough
287
00:20:23,267 --> 00:20:26,827
to cause, literally, a
separation of some body parts.
288
00:20:28,800 --> 00:20:31,100
But these
highly intelligent hunters
289
00:20:31,133 --> 00:20:33,603
may have a more specific motive.
290
00:20:33,633 --> 00:20:37,503
Killer whales will kill
blue whales and fin whales
291
00:20:37,533 --> 00:20:41,433
and eat their tongues because
they think they're tasty.
292
00:20:41,467 --> 00:20:46,497
Has some killer whale got
the taste for sea lion heads?
293
00:20:47,700 --> 00:20:50,870
But are killer
whales really to blame
294
00:20:50,900 --> 00:20:53,530
or are they just
an easy scapegoat?
295
00:20:54,767 --> 00:20:58,127
While killer whales are known
to play with their food,
296
00:20:58,167 --> 00:21:01,297
there's no documented
cases of killer whales
297
00:21:01,333 --> 00:21:04,773
actually ripping the heads off
their sea lion prey.
298
00:21:07,067 --> 00:21:10,727
The fact that these sea lions
have simply been decapitated
299
00:21:10,767 --> 00:21:13,697
and none of their juicy
blubber consumed
300
00:21:13,733 --> 00:21:17,503
leads me to think that it
was not a natural predator
301
00:21:17,533 --> 00:21:20,073
such as sharks or killer whales.
302
00:21:22,200 --> 00:21:25,200
With suspects
thin on the ground,
303
00:21:25,233 --> 00:21:28,273
the case is in danger
of going cold.
304
00:21:30,900 --> 00:21:33,230
But several of the sea lion
carcasses
305
00:21:33,267 --> 00:21:36,567
hold an easily overlooked clue,
306
00:21:36,600 --> 00:21:39,630
what appear
to be gunshot wounds.
307
00:21:41,200 --> 00:21:44,600
Fishermen have an uneasy
relationship with sea lions
308
00:21:44,633 --> 00:21:49,533
because they're competing with
these sea lions for the same fish stock.
309
00:21:49,567 --> 00:21:53,527
In recent years, stocks
of wild salmon have plummeted
310
00:21:53,567 --> 00:21:55,097
in the Vancouver area.
311
00:21:56,800 --> 00:21:59,170
The reasons why are complex,
312
00:21:59,200 --> 00:22:04,430
but an overpopulation of sea lions
is sometimes blamed as the cause.
313
00:22:04,467 --> 00:22:05,897
They eat a lot of fish.
314
00:22:05,933 --> 00:22:08,173
They have a habit
of breaking nets.
315
00:22:08,200 --> 00:22:11,070
This can all make
local fishermen very upset.
316
00:22:12,100 --> 00:22:15,200
And there have been
documented cases
317
00:22:15,233 --> 00:22:19,073
where some fishermen
have injured, shot,
318
00:22:19,067 --> 00:22:22,767
um, taken out sea lions,
which is really unfortunate.
319
00:22:24,800 --> 00:22:28,930
But if some fishermen
are shooting these sea lions,
320
00:22:28,967 --> 00:22:31,627
why would their heads
also be missing?
321
00:22:33,567 --> 00:22:36,367
They're protected.
They should not be harmed.
322
00:22:36,400 --> 00:22:39,570
Harming a sea lion
is breaking the law.
323
00:22:39,600 --> 00:22:42,670
The penalty for
harming a sea lion in Canada
324
00:22:42,700 --> 00:22:46,500
is a massive fine of
half a million dollars
325
00:22:46,533 --> 00:22:49,873
or a potential two-year jail
sentence.
326
00:22:49,900 --> 00:22:54,070
Fishermen could be shooting
the sea lion in the head
327
00:22:54,067 --> 00:22:57,627
and then decapitating it to
remove evidence of the fact
328
00:22:57,667 --> 00:22:59,867
that they shot the sea lion.
329
00:22:59,900 --> 00:23:03,370
If you cut off the head, you
of course remove the evidence
330
00:23:03,400 --> 00:23:06,230
of it having been shot
and you create a mystery.
331
00:23:12,067 --> 00:23:13,267
With mounting evidence
332
00:23:13,300 --> 00:23:17,830
that humans are behind
Vancouver's decapitated sea lions,
333
00:23:17,867 --> 00:23:21,527
this decade-long mystery
might finally be solved.
334
00:23:21,567 --> 00:23:25,097
And with citizens and
law enforcement on high alert,
335
00:23:25,133 --> 00:23:27,273
hopefully it's only
a matter of time
336
00:23:27,300 --> 00:23:30,700
before those responsible
are brought to justice.
337
00:23:43,433 --> 00:23:48,633
In 2015, scientists are mapping the
bottom of Lake Constance, Switzerland
338
00:23:48,667 --> 00:23:51,097
with state-of-the-art
sonar scanners
339
00:23:51,133 --> 00:23:54,203
when they detect
an unexpected anomaly.
340
00:23:55,600 --> 00:24:00,800
Beneath the surface, they find
170 large stone mounds
341
00:24:00,833 --> 00:24:03,773
that form an incredible
unbroken chain
342
00:24:03,800 --> 00:24:07,330
running for six miles
parallel to the shore.
343
00:24:07,367 --> 00:24:12,727
No one knows who or what created
this inexplicable formation of rocks,
344
00:24:12,767 --> 00:24:15,397
but can fresh scientific
analysis
345
00:24:15,433 --> 00:24:19,333
shed new light
on this megalithic mystery?
346
00:24:27,067 --> 00:24:29,727
The discovery
of this strange configuration
347
00:24:29,767 --> 00:24:32,297
of underwater rocks
in Lake Constance
348
00:24:32,333 --> 00:24:35,303
is soon picked up
by the European press
349
00:24:35,333 --> 00:24:39,073
who dub it the Swiss Stonehenge.
350
00:24:39,100 --> 00:24:42,900
These are very strange piles
of stone.
351
00:24:43,967 --> 00:24:48,167
They're 100-foot wide
and 5-foot high.
352
00:24:48,200 --> 00:24:53,900
Each pile is made up of
thousands of individual large stones.
353
00:24:56,567 --> 00:24:58,627
There are many, many, of them
354
00:24:58,667 --> 00:25:01,867
and they stretch six miles
around the coast.
355
00:25:04,200 --> 00:25:07,870
When archaeologists are
confronted with an anomaly,
356
00:25:07,900 --> 00:25:11,330
the first thing
we ask ourselves is,
357
00:25:11,367 --> 00:25:15,327
"Is this a man-made structure
or is this a natural formation?"
358
00:25:16,367 --> 00:25:17,967
So one reason for thinking
359
00:25:18,067 --> 00:25:21,267
these might just be natural
arrangements of stone
360
00:25:21,300 --> 00:25:23,900
is that if you look
at the total weight,
361
00:25:23,933 --> 00:25:28,473
you see 78,000 tons of rock.
362
00:25:28,500 --> 00:25:30,800
If these stones
had been put there by hand,
363
00:25:30,833 --> 00:25:33,373
then that would have taken
an incredible effort.
364
00:25:35,100 --> 00:25:40,800
What natural force could be capable
of moving and assembling this formation?
365
00:25:42,967 --> 00:25:46,197
Glaciers may appear static
when you look at them from the outset
366
00:25:46,233 --> 00:25:48,433
but they are, in fact,
constantly moving.
367
00:25:50,333 --> 00:25:54,073
As these huge walls
of ice advance and retreat,
368
00:25:54,067 --> 00:25:56,527
they have the power
to carve out valleys
369
00:25:56,567 --> 00:26:00,067
and move huge amounts of stone.
370
00:26:00,067 --> 00:26:03,067
These stones can find
themselves left behind
371
00:26:03,067 --> 00:26:04,727
when the glacier retreats.
372
00:26:06,133 --> 00:26:07,933
Twenty thousand years ago,
373
00:26:07,967 --> 00:26:11,297
glaciers covered
a vast area of the Alps
374
00:26:11,333 --> 00:26:14,133
including present day
Lake Constance.
375
00:26:16,067 --> 00:26:20,527
So could the Swiss Stonehenge
have been formed by a glacier?
376
00:26:22,367 --> 00:26:24,197
To put this theory to the test,
377
00:26:24,233 --> 00:26:28,833
the mapping team turn more high-tech
equipment on the underwater stones.
378
00:26:31,800 --> 00:26:37,070
Scientists use GPR, or ground
penetrating radar, to survey the site.
379
00:26:37,100 --> 00:26:43,270
It gives them an idea of any
structures that are below the surface.
380
00:26:43,300 --> 00:26:47,730
The data it beams back
reveals something totally unexpected.
381
00:26:51,067 --> 00:26:55,327
The Swiss Stonehenge sits well
above the mineral deposits
382
00:26:55,367 --> 00:26:58,197
left by the retreating glacier,
383
00:26:58,233 --> 00:27:01,573
meaning these stone mounds
were placed here
384
00:27:01,600 --> 00:27:06,130
thousands of years later
and are man-made.
385
00:27:06,167 --> 00:27:08,167
What on earth are they?
386
00:27:08,967 --> 00:27:10,797
It's a real mystery.
387
00:27:25,200 --> 00:27:28,570
When scientists discover that
a strange formation of rocks
388
00:27:28,600 --> 00:27:32,700
beneath the surface of a lake
in Switzerland is man-made,
389
00:27:32,733 --> 00:27:35,803
it raises more questions
than it answers.
390
00:27:36,967 --> 00:27:41,197
78,000 tons of stones
are involved.
391
00:27:41,233 --> 00:27:46,073
If it was man-made, it would
be a monumental effort.
392
00:27:48,067 --> 00:27:51,227
In 2019,
archaeologists returned to the site
393
00:27:51,267 --> 00:27:54,767
with the mission of
unlocking its secrets.
394
00:27:57,100 --> 00:27:59,870
If they find out when these
structures were built,
395
00:27:59,900 --> 00:28:04,630
it might help reveal who made
them and for what purpose.
396
00:28:06,567 --> 00:28:11,467
The team dig trenches and take
core samples around the rocks
397
00:28:11,500 --> 00:28:13,630
which they date back at the lab.
398
00:28:19,400 --> 00:28:22,600
It would appear as though
these enigmatic stone piles
399
00:28:22,633 --> 00:28:27,303
uh, were placed there
over 5,000 years ago.
400
00:28:29,267 --> 00:28:32,327
These stone platforms
date to the Neolithic
401
00:28:32,367 --> 00:28:36,227
and they're actually older
than Stonehenge itself.
402
00:28:37,367 --> 00:28:40,397
When we're talking
about the Neolithic period,
403
00:28:40,433 --> 00:28:42,733
they're doing all sorts of weird
404
00:28:42,767 --> 00:28:45,367
and wonderful things
with giant rocks
405
00:28:45,400 --> 00:28:47,970
and we can see
that across Europe.
406
00:28:50,567 --> 00:28:54,497
But the underwater
location of these Stone Age structures
407
00:28:54,533 --> 00:28:56,673
makes them particularly unique
408
00:28:56,700 --> 00:28:59,330
and their purpose
all the more puzzling.
409
00:29:01,900 --> 00:29:06,370
Could the answer lie in the
close proximity of the stone piles
410
00:29:06,400 --> 00:29:08,700
to the water's edge?
411
00:29:08,733 --> 00:29:11,203
They do bear
a striking resemblance
412
00:29:11,233 --> 00:29:15,933
to similar platforms in the
outer Hebrides in Scotland,
413
00:29:15,967 --> 00:29:20,067
and those platforms
are village sites.
414
00:29:20,100 --> 00:29:23,270
Known as crannogs,
these artificial rock islands
415
00:29:23,300 --> 00:29:26,870
are believed to be the sites
of ancient wooden houses.
416
00:29:27,867 --> 00:29:29,497
This house was built
on this lake
417
00:29:29,533 --> 00:29:35,333
because it provided them with a ready
source of food and a ready source of safety.
418
00:29:35,367 --> 00:29:37,727
But unlike the
crannogs in Scotland,
419
00:29:37,767 --> 00:29:41,867
the Swiss mounds don't have
any telltale signs of the bridges
420
00:29:41,900 --> 00:29:45,200
that would have been necessary
to connect to dry land.
421
00:29:47,300 --> 00:29:49,170
Their absence opens the door
422
00:29:49,200 --> 00:29:51,630
to an entirely different
possibility.
423
00:29:54,667 --> 00:29:59,427
What if these stone piles
weren't built in water after all?
424
00:29:59,467 --> 00:30:01,297
Lake levels go up and down
425
00:30:01,333 --> 00:30:05,303
and actually, we know that
during the Neolithic period,
426
00:30:05,333 --> 00:30:08,233
the lake levels would be much
lower than they are today.
427
00:30:09,533 --> 00:30:12,073
So therefore, the stones could
have actually been on dry land.
428
00:30:13,633 --> 00:30:15,733
If they were built on dry land,
429
00:30:15,767 --> 00:30:19,797
what purpose could these
rounded stone circles have served?
430
00:30:21,100 --> 00:30:22,930
Researchers have long speculated
431
00:30:22,967 --> 00:30:27,027
that other ancient sites have
a hidden celestial meaning.
432
00:30:29,333 --> 00:30:32,603
There's various arguments about
the Pyramids of Giza lining up with Orion,
433
00:30:32,633 --> 00:30:37,633
and, of course, Stonehenge is most
famously associated with various star maps.
434
00:30:37,667 --> 00:30:42,497
We know that Neolithic people
were interested in the seasons
435
00:30:42,533 --> 00:30:44,603
and measuring these things.
436
00:30:44,633 --> 00:30:48,503
Could the Swiss
Stonehenge be some kind of star map
437
00:30:48,533 --> 00:30:50,473
or seasonal measuring tool?
438
00:30:52,367 --> 00:30:55,767
Turns out this long line
of underwater stones
439
00:30:55,800 --> 00:31:01,930
appears to line up with the sunrise
and sunset on the 21st of June,
440
00:31:01,967 --> 00:31:05,897
which happens to be
the longest day of the year.
441
00:31:17,667 --> 00:31:21,367
The stone formations discovered
in Lake Constance are fascinating
442
00:31:21,400 --> 00:31:23,670
and they remain a mystery.
443
00:31:23,700 --> 00:31:28,900
One theory states that they were designed
to align to different solar phenomenon.
444
00:31:30,467 --> 00:31:33,097
The stone
piles do seem to line up
445
00:31:33,133 --> 00:31:36,203
with the sunrise and sunset
on the 21st of June,
446
00:31:36,233 --> 00:31:39,073
the northern hemisphere's
summer solstice.
447
00:31:40,467 --> 00:31:43,067
Initial thoughts are,
"Yes, these align.
448
00:31:43,100 --> 00:31:45,700
That's really exciting.
We're seeing something."
449
00:31:45,733 --> 00:31:47,903
But actually
when they start surveying
450
00:31:47,933 --> 00:31:51,273
more and more of them,
that pattern just disappears.
451
00:31:56,833 --> 00:32:01,873
So the Swiss Stonehenge
doesn't match with the stars,
452
00:32:01,900 --> 00:32:06,100
but that doesn't mean its purpose
wasn't aimed at the heavens.
453
00:32:06,133 --> 00:32:10,573
In my opinion, the most likely explanation
for these incredible stone piles,
454
00:32:10,600 --> 00:32:14,470
um, is that there was
some kind of monument
455
00:32:14,500 --> 00:32:16,970
to do with funerary rights
or religion.
456
00:32:18,767 --> 00:32:20,597
Throughout our entire history,
457
00:32:20,633 --> 00:32:23,903
humans have built magnificent
monuments to mark death
458
00:32:23,933 --> 00:32:26,073
and our passage
to the afterlife.
459
00:32:27,700 --> 00:32:31,400
But how might the Swiss Stonehenge
have been used in this way?
460
00:32:31,433 --> 00:32:35,673
We see quite a few megalithic
structures dating to the Neolithic
461
00:32:35,700 --> 00:32:39,170
and some across this region
as well, which act as tombs.
462
00:32:40,533 --> 00:32:43,403
But no bones or
chambers have been found
463
00:32:43,433 --> 00:32:45,903
inside the stone piles.
464
00:32:45,933 --> 00:32:51,733
Could the remains of the dead have
been placed on top of the rocks instead?
465
00:32:51,767 --> 00:32:54,827
They may have actually been
some sort of burial platform.
466
00:32:56,967 --> 00:33:01,827
These mounds might
have acted as altars for water burials
467
00:33:01,867 --> 00:33:05,097
where bodies are placed on
the rocks in shallow water...
468
00:33:06,300 --> 00:33:09,100
and left to be decomposed
by the lake.
469
00:33:10,067 --> 00:33:12,527
It's a very complicated scenario
470
00:33:12,567 --> 00:33:14,067
and we need to investigate more,
471
00:33:14,067 --> 00:33:17,067
because ultimately what
this site is, is a mystery.
472
00:33:19,367 --> 00:33:23,367
So the true purpose of the Swiss
Stonehenge remains unknown
473
00:33:23,400 --> 00:33:27,070
and some people believe we may
never reveal its secrets,
474
00:33:27,067 --> 00:33:30,527
but similar searches of
Switzerland's other alpine lakes
475
00:33:30,567 --> 00:33:32,267
are already taking place
476
00:33:32,300 --> 00:33:35,070
and future discoveries
may reveal more
477
00:33:35,100 --> 00:33:38,100
about this baffling
underwater wonder.
478
00:33:44,700 --> 00:33:47,300
Each year, dozens of cargo ships
479
00:33:47,333 --> 00:33:51,933
crossing the world's oceans
vanish for unknown reasons.
480
00:33:51,967 --> 00:33:54,227
Some of these vessels
disappear so quickly,
481
00:33:54,267 --> 00:33:58,197
they take all clues as
to why they sank with them.
482
00:33:58,233 --> 00:34:02,433
But can a terrifying
viral video shed new light
483
00:34:02,467 --> 00:34:06,697
on what's causing some ships
to sink without a trace?
484
00:34:11,767 --> 00:34:13,927
It's January 2021
485
00:34:13,967 --> 00:34:17,767
and the MV Arvin
is at anchor in the Black Sea
486
00:34:17,800 --> 00:34:20,200
close to the northern coast
of Turkey.
487
00:34:26,767 --> 00:34:32,067
As the cargo ship rides rough
swells, disaster strikes.
488
00:34:34,767 --> 00:34:36,127
Mayday! Mayday!
489
00:34:38,200 --> 00:34:41,430
This must be a truly,
truly, terrifying experience.
490
00:34:41,467 --> 00:34:44,827
The crew are on a ship
that's been torn in two.
491
00:34:44,867 --> 00:34:47,267
Mayday! Mayday!
This is cargo vessel Arvin.
492
00:34:47,300 --> 00:34:48,630
Mayday! Mayday!
493
00:34:49,467 --> 00:34:52,597
Arvin..
494
00:34:52,633 --> 00:34:55,303
There was no warning signs
and that to me was just like,
495
00:34:55,333 --> 00:34:57,873
"Holy cow! People are going
to die on this thing."
496
00:35:03,200 --> 00:35:06,170
The ship sinks
within a matter of minutes
497
00:35:06,200 --> 00:35:09,870
disappearing beneath the waves
in two pieces.
498
00:35:11,667 --> 00:35:15,297
Only six of its 12 crew
managed to be saved,
499
00:35:15,333 --> 00:35:17,073
managed to escape.
500
00:35:18,267 --> 00:35:19,827
How in the heck can this happen?
501
00:35:19,867 --> 00:35:21,627
You know, this thing's
made out of steel.
502
00:35:21,667 --> 00:35:24,697
It's, you know, welded,
it's put together.
503
00:35:25,700 --> 00:35:27,170
What would break a ship?
504
00:35:30,967 --> 00:35:32,597
The footage is chilling,
505
00:35:32,633 --> 00:35:36,233
but what causes this sudden
and deadly disaster?
506
00:35:37,633 --> 00:35:40,833
We know how dangerous
the Black Sea can be
507
00:35:40,867 --> 00:35:42,797
at certain times of the year
508
00:35:42,833 --> 00:35:44,773
and with certain
weather conditions.
509
00:35:47,967 --> 00:35:51,067
The strong winds
that sweep across the region
510
00:35:51,067 --> 00:35:54,927
are capable of whipping up
waves as high as 60 feet.
511
00:36:01,433 --> 00:36:05,233
But in rough seas, it's not
just a huge single wave
512
00:36:05,267 --> 00:36:07,527
that can pose a threat to ships.
513
00:36:08,767 --> 00:36:12,767
As the ship travels through
rough, rough seas,
514
00:36:12,800 --> 00:36:15,870
you can get quite
dynamic stresses
515
00:36:15,900 --> 00:36:18,670
being applied
to the ship's heart.
516
00:36:18,700 --> 00:36:20,630
The hull is actually bent here
517
00:36:20,667 --> 00:36:22,867
and there depending
on the power of the waves,
518
00:36:22,900 --> 00:36:24,570
depending on which way
the waves are going.
519
00:36:27,533 --> 00:36:30,503
A particularly
dangerous scenario can unfold
520
00:36:30,533 --> 00:36:35,733
when the front and back ends of
the ship are riding two different waves
521
00:36:35,767 --> 00:36:39,097
leaving the weight at the
center of the ship unsupported.
522
00:36:43,067 --> 00:36:46,097
This phenomenon
is known as sagging
523
00:36:46,133 --> 00:36:48,603
and in severe weather
conditions it's been known
524
00:36:48,633 --> 00:36:52,873
to seriously damage
or even sink ships.
525
00:36:52,900 --> 00:36:55,400
The question is,
are the wave conditions alone
526
00:36:55,433 --> 00:37:00,133
enough to explain why
the MV Arvin broke in two?
527
00:37:00,167 --> 00:37:02,427
On the day it snaps in half,
528
00:37:02,467 --> 00:37:05,197
the Arvin is experiencing
choppy conditions
529
00:37:05,233 --> 00:37:08,103
but it's nothing out of the
ordinary for the Black Sea.
530
00:37:08,133 --> 00:37:12,333
This puts stress on the hull,
but the ship's designed to take it.
531
00:37:12,367 --> 00:37:14,797
Ships only get
pushed beyond these limits
532
00:37:14,833 --> 00:37:17,073
in the most extreme weather...
533
00:37:18,233 --> 00:37:20,073
which has led some people
to believe
534
00:37:20,100 --> 00:37:23,530
there could be more going on
than meets the eye.
535
00:37:23,567 --> 00:37:26,267
Did something below deck
cause this disaster?
536
00:37:38,533 --> 00:37:42,233
When a cargo ship snaps
in two in the Black Sea
537
00:37:42,267 --> 00:37:44,827
and sinks in a matter
of minutes,
538
00:37:44,867 --> 00:37:48,067
people look to the rough seas
for an explanation.
539
00:37:50,900 --> 00:37:53,970
But could the true cause
of this maritime disaster
540
00:37:54,067 --> 00:37:57,767
lie below deck,
in the belly of the ship?
541
00:38:01,300 --> 00:38:06,400
The contents of the ship, the
cargo and how it's been stowed
542
00:38:06,433 --> 00:38:12,473
and the weight of the cargo of
course as well, is also really important.
543
00:38:12,500 --> 00:38:17,270
Is this ship transporting
anything dangerous in its hold?
544
00:38:17,300 --> 00:38:21,500
The MV Arvin is carrying urea
which is a granular substance
545
00:38:21,533 --> 00:38:24,103
and it's not normally
considered hazardous.
546
00:38:25,733 --> 00:38:29,703
Urea is an inert
and non-flammable product
547
00:38:29,733 --> 00:38:31,773
often used as fertilizer...
548
00:38:33,533 --> 00:38:36,873
but even supposedly
safe cargos like this
549
00:38:36,900 --> 00:38:40,200
can turn deadly
in the wrong conditions.
550
00:38:41,833 --> 00:38:43,473
When cargo ships are loaded,
551
00:38:43,500 --> 00:38:46,730
the weight needs to be
distributed evenly.
552
00:38:48,467 --> 00:38:54,267
An unbalanced ship can list
or tilt dangerously once at sea...
553
00:38:54,300 --> 00:38:59,100
and in worst-case scenarios,
it can even capsize.
554
00:39:04,633 --> 00:39:09,403
But could an unstable cargo
hold the power to rip a ship in two?
555
00:39:10,667 --> 00:39:12,497
Unlike container ships
556
00:39:12,533 --> 00:39:16,133
which can have thousands
of separate metal boxes,
557
00:39:16,167 --> 00:39:18,897
the Arvin is a bulk carrier.
558
00:39:18,933 --> 00:39:23,903
MV Arvin had four separate
holes to put their cargo in.
559
00:39:23,933 --> 00:39:26,133
It's dry bulk cargo.
560
00:39:27,367 --> 00:39:30,767
Huge loose loads
such as grain or sand
561
00:39:30,800 --> 00:39:33,070
are poured directly
into the ship.
562
00:39:35,767 --> 00:39:39,797
A rare poorly understood
phenomenon can strike at sea
563
00:39:39,833 --> 00:39:44,573
that instantly transforms
these safe dry heaps of material
564
00:39:44,600 --> 00:39:48,370
into a deadly
ship-sinking force.
565
00:39:48,400 --> 00:39:53,570
If liquid or water is
introduced into a dry bulk cargo
566
00:39:53,600 --> 00:39:56,100
it can become semi-liquefied,
567
00:39:56,133 --> 00:39:59,673
basically turn into a mushy
jelly or pudding
568
00:39:59,700 --> 00:40:01,970
and start sliding around.
569
00:40:03,900 --> 00:40:06,500
This is known as liquefaction.
570
00:40:09,600 --> 00:40:14,070
If small coarse substances
like sand contain moisture,
571
00:40:14,100 --> 00:40:16,300
with enough disturbance
or vibration,
572
00:40:16,333 --> 00:40:20,973
the molecules can become
energized and instantly change state.
573
00:40:23,367 --> 00:40:24,797
For ships at sea,
574
00:40:24,833 --> 00:40:28,073
this can lead to devastating
consequences.
575
00:40:28,100 --> 00:40:32,970
The liquefied cargo can then move
around freely within the hold of the ship
576
00:40:33,000 --> 00:40:36,500
which can wreak havoc with
the ship's weight distribution.
577
00:40:38,667 --> 00:40:42,267
Does the
Arvin's cargo turn to liquid
578
00:40:42,300 --> 00:40:45,370
and slosh dangerously
around inside the ship...
579
00:40:46,867 --> 00:40:50,997
causing a weight overload that
snaps the vessel clean in two?
580
00:40:55,833 --> 00:40:57,403
For this to be the case,
581
00:40:57,433 --> 00:41:02,903
moisture must have found a
way into its watertight cargo holds.
582
00:41:02,933 --> 00:41:06,433
That vessel was
old. It was almost 50 years old.
583
00:41:07,467 --> 00:41:09,727
They actually did
an inspection on it
584
00:41:09,767 --> 00:41:12,627
and they were complaining
about the rust on the deck,
585
00:41:12,667 --> 00:41:14,967
the poor maintenance
of the vessel.
586
00:41:16,367 --> 00:41:20,297
Did water seep through
the Arvin's rusty bulkheads,
587
00:41:20,333 --> 00:41:24,603
enter the cargo holds and help
trigger this disaster?
588
00:41:26,467 --> 00:41:28,727
This vessel
being as old as it was,
589
00:41:28,767 --> 00:41:30,227
I think had something
to do with it.
590
00:41:34,167 --> 00:41:36,397
The footage captured
on the MV Arvin
591
00:41:36,433 --> 00:41:38,633
provides a rare chilling glimpse
592
00:41:38,667 --> 00:41:42,467
of the final moments
on board a doomed ship.
593
00:41:42,500 --> 00:41:46,470
Cargo liquefaction could have
played a key role in this tragic event
594
00:41:46,500 --> 00:41:50,300
and it's thought up to ten
cargo ships a year could be lost
595
00:41:50,333 --> 00:41:53,273
due to this poorly
understood phenomenon.
596
00:41:53,300 --> 00:41:56,270
Footage like this is helping
scientists and shipbuilders
597
00:41:56,300 --> 00:41:59,900
better understand its causes
and consequences
598
00:42:00,067 --> 00:42:05,197
and their urgent work could help
prevent more disasters in the future.
