1
00:00:05,873 --> 00:00:08,741
Narrator: A land
of ancient ruins,
2
00:00:08,843 --> 00:00:13,245
Windswept mountains and
deep foreboding lakes.
3
00:00:14,315 --> 00:00:20,335
Scotland is a nation steeped
in myth, legend and mystery.
4
00:00:21,272 --> 00:00:24,773
And no mystery is more
enduring than that of
5
00:00:24,875 --> 00:00:28,143
The loch ness monster.
6
00:00:29,814 --> 00:00:32,981
Imagine if we could
empty the oceans,
7
00:00:33,084 --> 00:00:36,335
Letting the world's
water drain away
8
00:00:38,372 --> 00:00:42,741
To reveal the secrets of
sea floors and lake beds.
9
00:00:44,211 --> 00:00:46,478
Now we can.
10
00:00:46,580 --> 00:00:50,015
Using accurate data and
astonishing technology to
11
00:00:50,117 --> 00:00:54,269
Bring light once
again to a lost world.
12
00:00:56,707 --> 00:01:00,309
Can a killing field on the
shores of a siberian lake
13
00:01:00,478 --> 00:01:04,413
Shed light on the world's
most famous monster?
14
00:01:04,515 --> 00:01:07,132
Olga: This is the pelvic bone,
these are the shoulder blades
15
00:01:07,234 --> 00:01:08,967
And vertebrae.
16
00:01:09,070 --> 00:01:12,037
Narrator: Can a marine robot
finally uncover the loch's
17
00:01:12,139 --> 00:01:15,007
Strangest secret of all?
18
00:01:17,078 --> 00:01:20,479
And could a long-lost
shipwreck really be a boat
19
00:01:20,581 --> 00:01:23,465
Destroyed by nessie herself?
20
00:01:24,435 --> 00:01:27,402
Adrian: When people said that
john cobb's crash was caused
21
00:01:27,505 --> 00:01:30,939
By the loch ness monster,
in a sense they were right.
22
00:01:31,542 --> 00:01:37,780
(theme music plays).
23
00:01:43,804 --> 00:01:47,773
Narrator: 23 miles long
and over 700 feet deep,
24
00:01:47,875 --> 00:01:52,411
Loch ness is the biggest
body of fresh water in
the british isles.
25
00:01:54,081 --> 00:01:58,333
100 miles north of the
scottish capital, edinburgh,
26
00:01:58,435 --> 00:02:01,870
It slices the
highlands in two.
27
00:02:03,507 --> 00:02:06,809
Many people are
convinced that its deep,
28
00:02:06,911 --> 00:02:10,946
Dark waters harbor a
secretive creature.
29
00:02:11,916 --> 00:02:15,501
Now, a new expedition hopes
to solve the mystery of the
30
00:02:15,603 --> 00:02:19,371
Loch ness monster
once and for all.
31
00:02:19,473 --> 00:02:23,609
And discover whether
it's myth or reality.
32
00:02:24,445 --> 00:02:25,677
Craig: In terms of
the mission plan now,
33
00:02:25,779 --> 00:02:27,112
You can see we've dived.
34
00:02:27,214 --> 00:02:28,914
We're already down at
200 meters of water.
35
00:02:29,016 --> 00:02:30,532
I don't think we've
been to this altitude
36
00:02:30,634 --> 00:02:32,201
In loch ness before anyway.
37
00:02:32,303 --> 00:02:33,602
Adrian: Before.
38
00:02:33,704 --> 00:02:34,736
Craig: So this will be the
best resolution achieved
39
00:02:34,839 --> 00:02:36,939
In the loch to date.
40
00:02:37,041 --> 00:02:40,876
Narrator: Scotland's stunning
natural landscape includes
41
00:02:40,978 --> 00:02:45,948
Over 30,000 lochs, the
local word for lakes.
42
00:02:47,468 --> 00:02:51,904
And for most of its history,
loch ness is just one of them.
43
00:02:53,440 --> 00:02:57,342
But all that changes
in the early 1930s,
44
00:02:58,279 --> 00:03:01,747
When a new road
brings new visitors
45
00:03:01,849 --> 00:03:06,034
And a series of strange
sightings begins,
46
00:03:08,072 --> 00:03:12,007
Which culminate in
an image captured by a
visiting english surgeon.
47
00:03:13,410 --> 00:03:17,212
One of the most iconic
photographs ever taken.
48
00:03:18,315 --> 00:03:19,848
Adrian: The surgeon's
picture, of course,
49
00:03:19,950 --> 00:03:24,736
Is a picture which everybody
in the western world will know.
50
00:03:25,773 --> 00:03:30,075
Narrator: Loch ness has
been drawing fascinated
visitors ever since.
51
00:03:32,513 --> 00:03:36,648
Eight decades later, over a
million tourists are still drawn
52
00:03:36,750 --> 00:03:41,503
To the shores of the loch every
year, in search of nessie.
53
00:03:43,874 --> 00:03:45,440
Woman: My aunt, you
saw it, didn't you?
54
00:03:45,542 --> 00:03:47,075
Woman: Yeah, oh, distinctly.
55
00:03:47,177 --> 00:03:48,877
I don't doubt
there's a monster.
56
00:03:48,979 --> 00:03:50,846
Man: I saw this hump.
57
00:03:50,948 --> 00:03:53,799
Man: We saw the head
and the four humps.
58
00:03:53,901 --> 00:03:56,768
It was the very same
color as an elephant.
59
00:03:57,771 --> 00:04:00,005
Narrator: No fewer
than 1,000 people
60
00:04:00,174 --> 00:04:02,207
Have claimed to
see the monster.
61
00:04:02,309 --> 00:04:04,509
Man: It was the size
of a yacht hull.
62
00:04:04,612 --> 00:04:06,178
Man: It looked like a
submarine coming closer and
63
00:04:06,280 --> 00:04:09,214
Closer and you could
see the long neck.
64
00:04:09,316 --> 00:04:12,067
Narrator: And there's been a
recent surge in sightings.
65
00:04:12,169 --> 00:04:14,403
Man: So, I saw a dark
shape in the water.
66
00:04:14,505 --> 00:04:16,805
I was out further, towards
the other end of the castle.
67
00:04:16,907 --> 00:04:19,241
Something's moving,
between the trees.
68
00:04:19,343 --> 00:04:22,411
Woman: Oh my god, it's moving!
69
00:04:28,769 --> 00:04:32,804
Narrator: For many, nessie
is a sincerely held belief.
70
00:04:33,540 --> 00:04:38,277
Steve feltham saw
something unusual in 1991.
71
00:04:39,280 --> 00:04:43,015
Steve: I saw one thing in
the first year of being here.
72
00:04:43,117 --> 00:04:46,735
Something just shot across
the bay in front of me and
73
00:04:47,438 --> 00:04:49,071
You couldn't tell what it was.
74
00:04:49,173 --> 00:04:51,673
You could only see a spray of
water coming off of something,
75
00:04:51,775 --> 00:04:53,942
Like a torpedo.
76
00:04:54,878 --> 00:04:56,812
Narrator: Steve
was so fascinated,
77
00:04:56,914 --> 00:04:59,281
He set up a full-time vigil.
78
00:05:01,168 --> 00:05:04,069
Steve: To be honest I thought
all I need to do now is be
79
00:05:04,171 --> 00:05:06,538
Ready for the next
time with the camera,
80
00:05:06,640 --> 00:05:10,008
To take that
all-important photograph.
81
00:05:12,413 --> 00:05:16,748
Narrator: 28 years later,
he's still waiting.
82
00:05:19,336 --> 00:05:22,204
Man (over film): Loch
ness, on which the eyes
of the world are focused.
83
00:05:22,306 --> 00:05:25,907
Narrator: Scientists too
have been drawn to the loch,
84
00:05:26,010 --> 00:05:30,579
And their experiences have
been just as mixed as steve's.
85
00:05:31,415 --> 00:05:34,299
Man (over film): The hunt
is well and truly on.
86
00:05:37,037 --> 00:05:39,504
Narrator: All through
the 1970s and 80s,
87
00:05:39,606 --> 00:05:43,175
Major investigations traversed
the loch in the hope of making
88
00:05:43,277 --> 00:05:46,578
A genuine zoological
discovery.
89
00:05:46,680 --> 00:05:50,432
Most come back empty
handed, but not all.
90
00:05:51,101 --> 00:05:53,168
Reporter (over tv): The team
of scientists sweeping the
91
00:05:53,270 --> 00:05:55,737
Depths of loch ness said
tonight they've made sonar
92
00:05:55,839 --> 00:05:59,141
Contact with a large
unidentified object.
93
00:05:59,243 --> 00:06:01,877
They described it
as an unusual...
94
00:06:02,246 --> 00:06:05,280
Narrator: No sighting has
ever been properly confirmed.
95
00:06:07,634 --> 00:06:13,171
But expeditions like these
inspire naturalist adrian shine.
96
00:06:14,875 --> 00:06:18,543
He's been researching loch
ness for more than 40 years.
97
00:06:19,346 --> 00:06:21,580
Adrian: Much of the work that
we with the loch ness project
98
00:06:21,682 --> 00:06:24,066
Have been doing is biological.
99
00:06:24,168 --> 00:06:27,903
Counting fish, counting
plankton, that sort of thing.
100
00:06:28,005 --> 00:06:30,906
And that's why I
built a submarine.
101
00:06:31,008 --> 00:06:34,076
I recruited students and
that's why we collaborate
102
00:06:34,178 --> 00:06:36,745
With so many universities.
103
00:06:36,847 --> 00:06:41,500
But inevitably we've become
also intrigued by other
104
00:06:41,602 --> 00:06:43,568
Aspects of loch ness.
105
00:06:44,271 --> 00:06:47,839
Narrator: And no other
aspect intrigues adrian more,
106
00:06:47,941 --> 00:06:50,976
Than the biggest
question of all.
107
00:06:51,078 --> 00:06:53,695
Now, he's teamed
up with craig wallace,
108
00:06:53,781 --> 00:06:56,882
An expert in deep
water exploration.
109
00:06:58,102 --> 00:07:01,953
They're on board the
research boat deep scan,
110
00:07:02,039 --> 00:07:04,739
Hoping to reveal what's
inside loch ness in
111
00:07:04,842 --> 00:07:07,809
Greater detail than ever before.
112
00:07:07,911 --> 00:07:10,445
And even if they don't
find the monster,
113
00:07:10,547 --> 00:07:14,566
Adrian believes that 21st
century technology can explain
114
00:07:14,668 --> 00:07:17,602
What it is that people
have been seeing.
115
00:07:17,704 --> 00:07:19,971
Craig: We've got a vertical
range of 14 meters.
116
00:07:20,073 --> 00:07:21,840
Adrian: So you've got
a very high resolution.
117
00:07:21,942 --> 00:07:23,942
Craig: Very high resolution.
118
00:07:24,044 --> 00:07:26,144
We're actually gonna drop
down further to eight meters
so we're gonna double it again.
119
00:07:26,246 --> 00:07:27,746
Adrian: Okay. Okay.
120
00:07:27,848 --> 00:07:30,966
Narrator: To find a monster,
perhaps you need a monster.
121
00:07:31,835 --> 00:07:34,702
At the heart of this
expedition is this robotic
122
00:07:34,771 --> 00:07:38,640
Underwater vehicle, armed
with the latest sonar,
123
00:07:38,759 --> 00:07:43,044
It can even adjust its own
course to avoid obstacles.
124
00:07:43,147 --> 00:07:45,814
It's called munin.
125
00:07:46,383 --> 00:07:47,899
Craig: It's only now that
technology's getting up to
126
00:07:48,001 --> 00:07:50,902
That level where we can put
vehicles in autonomously,
127
00:07:51,004 --> 00:07:53,171
Where they're making
decisions on their own,
128
00:07:53,273 --> 00:07:55,841
Which allows you high
accuracy navigation.
129
00:07:59,112 --> 00:08:02,447
Narrator: The first thing adrian
and craig want munin to do
130
00:08:02,549 --> 00:08:06,101
Is to take a really close look
at the bottom of the loch.
131
00:08:14,344 --> 00:08:15,443
Captain: Clear.
132
00:08:15,546 --> 00:08:17,846
Prop, we're testing the prop.
133
00:08:20,968 --> 00:08:23,168
Narrator: As it travels
through the water,
134
00:08:23,270 --> 00:08:27,072
Munin sends signals that
reach 700 feet down.
135
00:08:28,408 --> 00:08:31,409
Some believe there might
be a huge cave there,
136
00:08:31,512 --> 00:08:35,447
The perfect spot for a large
creature to hide inside.
137
00:08:36,884 --> 00:08:40,735
If there is a cave, it will
show up as the signals bounce
138
00:08:40,837 --> 00:08:44,322
Back to munin and the
receiving systems on the
research vessel.
139
00:08:47,611 --> 00:08:52,414
And if munin was to detect not
just a cave, but a monster,
140
00:08:52,516 --> 00:08:54,966
What would it be like?
141
00:08:56,587 --> 00:08:59,638
The photograph that created
the most popular image
142
00:08:59,740 --> 00:09:02,173
Looks like a dinosaur.
143
00:09:03,644 --> 00:09:07,779
But could a dinosaur really
exist in the scottish highlands?
144
00:09:10,350 --> 00:09:13,802
The country's dramatic
landscape is made up of some
145
00:09:13,904 --> 00:09:16,938
Of the oldest rock
layers in the world.
146
00:09:17,057 --> 00:09:20,875
And embedded in them are
thousands of extraordinary
147
00:09:20,978 --> 00:09:24,713
Dinosaur fossils, which have
long drawn scientists to the
148
00:09:24,815 --> 00:09:29,417
Country, including
dr. Steve brusatte.
149
00:09:30,103 --> 00:09:32,203
Stephen: In the lagoons and
long the rivers and the lakes,
150
00:09:32,306 --> 00:09:34,272
You would have had dinosaurs.
151
00:09:34,374 --> 00:09:37,742
These kind of animals did
indeed live in scotland.
152
00:09:37,844 --> 00:09:40,412
There were sea monsters here.
153
00:09:40,514 --> 00:09:44,666
Narrator: But the question is,
are there any sea monsters now?
154
00:09:46,036 --> 00:09:49,604
The last known large dinosaurs
in scotland went extinct with
155
00:09:49,706 --> 00:09:53,341
The rest of their relatives
66 million years ago.
156
00:09:55,045 --> 00:09:59,914
And extinct animals don't just
suddenly reappear, or do they?
157
00:10:02,669 --> 00:10:06,571
In 1938, a fish caught off
the coast of south africa
158
00:10:06,673 --> 00:10:09,641
Shakes the scientific world.
159
00:10:10,711 --> 00:10:14,779
The coelacanth has long
been thought to be extinct.
160
00:10:14,881 --> 00:10:18,433
It had previously only ever
been seen in fossils over
161
00:10:18,535 --> 00:10:21,236
70 million years old.
162
00:10:21,338 --> 00:10:23,772
But the coelacanth,
it turns out,
163
00:10:23,874 --> 00:10:27,075
Has been hiding
in plain sight.
164
00:10:28,211 --> 00:10:31,846
Could something similar
have happened in loch ness?
165
00:10:31,948 --> 00:10:36,234
A supposedly extinct
prehistoric beast, lurking,
166
00:10:36,336 --> 00:10:39,738
Hidden from view,
in his peaty waters.
167
00:10:40,841 --> 00:10:44,476
For this to be even possible,
the loch ness we know today
168
00:10:44,578 --> 00:10:47,245
Would have to be a
very ancient lake.
169
00:10:47,347 --> 00:10:50,315
A lake from the time
of the dinosaurs.
170
00:10:51,601 --> 00:10:54,502
So is it?
171
00:10:54,604 --> 00:10:58,940
To find out, we'd need to peer
into the deepest recesses of
172
00:10:59,042 --> 00:11:02,644
The loch and examine
its very bedrock.
173
00:11:03,747 --> 00:11:05,914
But over 700 feet down,
174
00:11:06,016 --> 00:11:09,167
Loch ness is too deep
for most divers.
175
00:11:10,037 --> 00:11:14,873
Instead, we have munin, which
has now completed its scans,
176
00:11:14,975 --> 00:11:20,278
Giving us the data we need to
drain the waters from the loch.
177
00:11:26,136 --> 00:11:30,238
Slowly, the loch's
true scale is revealed.
178
00:11:35,912 --> 00:11:40,715
With steep side walls
plunging down, at its base,
179
00:11:40,801 --> 00:11:44,102
There are no signs
of any caves.
180
00:11:44,204 --> 00:11:48,339
Instead, just a barren plain
of soft, deep sediment.
181
00:11:52,145 --> 00:11:56,281
But with our new data we can
peel the sediment back too,
182
00:11:56,383 --> 00:11:58,733
To reveal in the
depths of the loch,
183
00:11:58,835 --> 00:12:02,270
A glistening layer
of glacial clay.
184
00:12:03,173 --> 00:12:06,007
Clay that can give us a more
detailed understanding of the
185
00:12:06,109 --> 00:12:09,160
Loch's history and
whether it could hold
186
00:12:09,246 --> 00:12:11,980
A prehistoric monster.
187
00:12:16,336 --> 00:12:19,104
For decades, scientists
are intrigued by these
188
00:12:19,206 --> 00:12:22,140
Ancient layers at the
bottom of the loch,
189
00:12:22,242 --> 00:12:26,911
And drill into the lake bed
to extract core samples.
190
00:12:28,949 --> 00:12:32,901
Adrian: That is a time capsule
of events within the loch.
191
00:12:34,971 --> 00:12:37,772
Narrator: They study
the core samples.
192
00:12:38,775 --> 00:12:41,609
And calculate that the
layer of clay marks the
193
00:12:41,711 --> 00:12:44,979
End of the last ice age.
194
00:12:45,081 --> 00:12:47,832
Adrian: So we've
got a problem,
195
00:12:47,934 --> 00:12:52,237
Loch ness was one big ice
cube until 10,000 years ago.
196
00:12:55,175 --> 00:12:58,576
Narrator: The dinosaurs went
extinct long before then.
197
00:13:00,413 --> 00:13:04,966
And even if some had somehow
managed to survive in scotland,
198
00:13:05,068 --> 00:13:08,903
They could never have
lived inside an ice cube.
199
00:13:09,005 --> 00:13:13,508
Stephen: There's just no
way that any of these
170 million year old
200
00:13:13,610 --> 00:13:17,946
Jurassic animals could have
ever lived in that lake.
201
00:13:19,749 --> 00:13:23,334
Narrator: So if a monster
does inhabit the loch,
202
00:13:23,436 --> 00:13:26,304
It's not a dinosaur.
203
00:13:26,406 --> 00:13:29,574
So what could it be?
204
00:13:30,811 --> 00:13:34,379
Perhaps there's a clue in
another famous sighting.
205
00:13:37,667 --> 00:13:42,337
In the spring of 1933, hotel
manager aldi mackay and her
206
00:13:42,439 --> 00:13:47,609
Husband john are driving along
the shore of loch ness when
207
00:13:47,711 --> 00:13:51,746
Suddenly they see something
moving through the water.
208
00:13:52,983 --> 00:13:55,667
The couple watch amazed
for a full minute,
209
00:13:55,769 --> 00:13:59,103
As what seems to be a creature
rolls around in the center of
210
00:13:59,206 --> 00:14:03,441
The loch and churns up
the water around it.
211
00:14:05,312 --> 00:14:10,281
Later, aldi tells a
reporter than the creature
looked like a whale.
212
00:14:12,669 --> 00:14:16,704
Her story becomes front page
news all around the world.
213
00:14:18,275 --> 00:14:22,744
Aldi took no photographs,
but in subsequent decades,
214
00:14:22,846 --> 00:14:26,848
Other sightings seem to match
this whale like description.
215
00:14:29,803 --> 00:14:34,839
So could the monster really
be a huge marine mammal?
216
00:14:36,076 --> 00:14:40,178
The problem is there is no
swimmable route from the sea
217
00:14:40,280 --> 00:14:43,815
To loch ness.
218
00:14:45,302 --> 00:14:47,702
And even if a whale like
creature could get into the
219
00:14:47,804 --> 00:14:51,272
Loch, there's a
bigger obstacle.
220
00:14:52,742 --> 00:14:58,079
Any saltwater beast would surely
die in a freshwater lake.
221
00:14:58,715 --> 00:15:01,065
Or would it?
222
00:15:02,402 --> 00:15:06,104
The answer to this question
may lie somewhere else,
223
00:15:06,206 --> 00:15:10,308
In the deepest and oldest
lake in the world.
224
00:15:19,235 --> 00:15:25,239
Narrator: At almost 400 miles
long, up to 49 miles wide,
225
00:15:26,042 --> 00:15:29,644
And in places a
full mile deep,
226
00:15:31,348 --> 00:15:36,634
Lake baikal is at least
25 million years old.
227
00:15:38,505 --> 00:15:42,507
4,000 miles away from scotland,
228
00:15:42,609 --> 00:15:45,443
This mega lake is so colossal,
229
00:15:45,545 --> 00:15:49,914
It can hold 3,000 times
more water than loch ness.
230
00:15:53,269 --> 00:15:57,205
And still have room
for a few monsters.
231
00:15:59,175 --> 00:16:02,543
Local folklore claims that
a dragon like creature
232
00:16:02,646 --> 00:16:05,880
Inhabits these icy waters.
233
00:16:07,083 --> 00:16:11,436
But it's not dragons
that local scientists
have been studying...
234
00:16:13,907 --> 00:16:17,542
Instead they've made a series
of startling discoveries that
235
00:16:17,644 --> 00:16:21,779
Might help solve the mystery
of how a sea mammal could
236
00:16:21,881 --> 00:16:24,966
Thrive back in loch ness.
237
00:16:26,403 --> 00:16:29,671
In the winter months, if local
people want to cross baikal,
238
00:16:29,773 --> 00:16:33,574
They don't go around the lake,
they just drive over it.
239
00:16:35,845 --> 00:16:39,881
On ice that's up
to five feet thick.
240
00:16:45,238 --> 00:16:48,973
Olga goriunova is part of a
joint russian canadian team
241
00:16:49,075 --> 00:16:52,360
That's been excavating
on the western shore.
242
00:16:54,581 --> 00:16:58,366
Olga: Usually when you
deal with research along
the shore of lake baikal,
243
00:16:58,468 --> 00:17:02,437
People tend to focus on
the ecology aspect only.
244
00:17:04,441 --> 00:17:06,007
The landscape.
245
00:17:06,109 --> 00:17:09,811
The wildlife and so on,
and all the surroundings.
246
00:17:12,615 --> 00:17:15,633
Narrator: Olga has made
a special study of an
ancient community
247
00:17:15,735 --> 00:17:20,138
That created stone age art
here over 4,000 years ago.
248
00:17:21,941 --> 00:17:25,643
Some of the creatures
they drew look familiar,
249
00:17:25,745 --> 00:17:30,948
But they're not loch ness
monsters or even dragons.
250
00:17:32,235 --> 00:17:35,570
Olga has a less
fanciful explanation.
251
00:17:37,006 --> 00:17:39,874
Olga: Here we have swans.
252
00:17:39,976 --> 00:17:43,244
This is a more
ancient drawing.
253
00:17:44,180 --> 00:17:47,865
And here we can see
groups of swans.
254
00:17:50,236 --> 00:17:53,104
Narrator: Along the lake's
shore is a site that plays a
255
00:17:53,206 --> 00:17:56,474
Crucial role in the
lives of these people.
256
00:17:57,894 --> 00:18:03,848
Olga: The oldest layer
of this site is more
than 9,000 years old.
257
00:18:05,568 --> 00:18:08,069
Here, we have a stack of dark
layers dating back to the
258
00:18:08,171 --> 00:18:11,873
Neolithic period, or
the new stone age.
259
00:18:14,978 --> 00:18:17,311
Narrator: Olga believes that
the ancient community here
260
00:18:17,413 --> 00:18:20,448
Used this place as a
stone age slaughterhouse.
261
00:18:24,304 --> 00:18:26,637
Olga: This is
very interesting.
262
00:18:26,739 --> 00:18:30,541
Here, the wall collapsed,
revealing bones.
263
00:18:31,978 --> 00:18:36,681
Look, this is the pelvic bone.
264
00:18:36,783 --> 00:18:41,369
These are the shoulder blades
and here is a vertebrae.
265
00:18:43,206 --> 00:18:44,906
Narrator: So what's
all this got to do with
266
00:18:45,008 --> 00:18:47,575
The loch ness monster?
267
00:18:49,245 --> 00:18:52,180
The connection is a creature
that these ancient humans were
268
00:18:52,282 --> 00:18:56,267
Butchering on the shores
of the fresh water lake.
269
00:18:59,706 --> 00:19:04,542
To find it, we must
first drain lake baikal.
270
00:19:05,845 --> 00:19:08,479
As the ice cracks and melts,
271
00:19:08,581 --> 00:19:11,999
Trillions of gallons of
freshwater flood out.
272
00:19:13,069 --> 00:19:16,637
And an unseen
landscape emerges,
273
00:19:16,739 --> 00:19:19,974
With vast quantities of
sediment piled high on the
274
00:19:20,076 --> 00:19:22,577
Immense lake bed.
275
00:19:23,513 --> 00:19:26,814
But if this sediment
is also pulled back,
276
00:19:26,916 --> 00:19:31,536
It reveals of evidence of
thousands of years of hunting.
277
00:19:33,039 --> 00:19:37,275
Bones everywhere with all
their meat hacked off.
278
00:19:38,411 --> 00:19:43,080
It quickly becomes
obvious that one animal
above all predominates.
279
00:19:44,184 --> 00:19:48,452
A sea creature that's familiar
to anyone in scotland.
280
00:19:50,006 --> 00:19:52,006
Seals.
281
00:19:53,843 --> 00:19:56,143
In every other
place on the planet,
282
00:19:56,246 --> 00:19:58,980
Seals are a saltwater creature.
283
00:20:00,583 --> 00:20:04,135
But the bones here
belong to the nerpa,
284
00:20:04,237 --> 00:20:07,438
A remarkable species of
seal that uniquely evolved
285
00:20:07,540 --> 00:20:10,741
To live in fresh water.
286
00:20:12,645 --> 00:20:16,047
But how did they first get
here, over 1,000 miles
287
00:20:16,149 --> 00:20:18,266
From the saltwater
of the sea?
288
00:20:19,569 --> 00:20:24,171
One possible explanation
is that 300,000 years ago,
289
00:20:24,274 --> 00:20:27,742
Baikal may have been
connected to the arctic ocean,
290
00:20:27,844 --> 00:20:31,245
But when the connection was
broken, the seals were trapped
291
00:20:31,347 --> 00:20:34,048
And so had to adapt.
292
00:20:36,803 --> 00:20:40,538
Could something similar
have happened in loch ness?
293
00:20:40,640 --> 00:20:44,375
Large sea creatures finding
their way to an inland lake
294
00:20:44,477 --> 00:20:48,045
And then evolving
to live there?
295
00:20:50,149 --> 00:20:54,402
Glacial geologist jeremy everest
uses the latest technology
296
00:20:54,504 --> 00:20:58,472
To study landscapes and the way
they can change over time.
297
00:21:01,444 --> 00:21:03,744
With an array of
computing power,
298
00:21:03,846 --> 00:21:07,014
Geologists can now model the
area of scotland around the
299
00:21:07,116 --> 00:21:10,201
Northern end of the
loch in fine detail.
300
00:21:12,205 --> 00:21:15,439
Jeremy also uses an
interactive 3d model that
301
00:21:15,541 --> 00:21:20,411
Works like a hologram where he
can play scientific moses with
302
00:21:20,513 --> 00:21:22,580
A wave of his hand.
303
00:21:23,683 --> 00:21:26,033
Jeremy: I can hold my hand
over the model and it'll rain,
304
00:21:26,135 --> 00:21:29,003
So I'm filling the, filling
the ocean and raising the
305
00:21:29,105 --> 00:21:31,405
Local sea level.
306
00:21:33,009 --> 00:21:36,510
Narrator: So what happens if
the water continues to rise?
307
00:21:36,612 --> 00:21:39,613
For example, at the
end of an ice age.
308
00:21:41,401 --> 00:21:43,768
Jeremy: Sea levels rise
because all the ice is melting
309
00:21:43,870 --> 00:21:45,936
And draining the waters
back into the oceans,
310
00:21:46,039 --> 00:21:50,975
Allowing water to
cross this area of land
and enter loch ness.
311
00:21:52,812 --> 00:21:55,713
There we have a marine
incursion with sea water
312
00:21:55,815 --> 00:21:58,532
Draining into the loch.
313
00:21:59,552 --> 00:22:02,203
Narrator: And if the
land barrier disappears,
314
00:22:02,305 --> 00:22:06,407
Could a creature like a
whale swim between the two?
315
00:22:07,176 --> 00:22:10,945
Lake baikal proves that salt
water animals can adapt to
316
00:22:11,047 --> 00:22:13,014
Live in fresh water.
317
00:22:13,983 --> 00:22:17,001
So a whale like creature
entering the loch at this time
318
00:22:17,103 --> 00:22:20,638
Might not be an impossibility.
319
00:22:21,341 --> 00:22:26,043
Although many geologists,
including jeremy, are
highly skeptical,
320
00:22:26,145 --> 00:22:29,580
And finally there's
another problem.
321
00:22:29,682 --> 00:22:34,001
Whales and seals are
mammals and breath air.
322
00:22:34,771 --> 00:22:38,606
If one was in the loch today,
every time it came up for air
323
00:22:38,708 --> 00:22:41,175
It would be spotted.
324
00:22:42,211 --> 00:22:46,514
So large sea mammals cannot
be the explanation for
325
00:22:46,616 --> 00:22:49,166
The loch ness monster.
326
00:22:49,268 --> 00:22:54,772
If she isn't a dinosaur
and can't be a whale,
327
00:22:55,842 --> 00:22:59,810
What could explain one of the
most famous sightings of all?
328
00:23:00,963 --> 00:23:04,999
In 1936, malcolm irvine
becomes the first person to
329
00:23:05,101 --> 00:23:10,638
Film a huge indistinct creature
swimming against the current.
330
00:23:14,444 --> 00:23:17,845
Many sightings since have
described a large animal doing
331
00:23:17,947 --> 00:23:21,215
The same, pushing against
the wind and water.
332
00:23:21,968 --> 00:23:26,570
Adrian: You will see a tree
trunk or log out on the loch,
333
00:23:26,672 --> 00:23:29,306
But then you realize
it isn't, it can't be.
334
00:23:29,409 --> 00:23:30,708
It can't be.
It's swimming.
335
00:23:30,810 --> 00:23:33,761
It's swimming
against the wind.
336
00:23:33,846 --> 00:23:36,847
Narrator: Surely nothing
but nessie could ever move
337
00:23:36,949 --> 00:23:39,767
Through water like this.
338
00:23:49,745 --> 00:23:53,647
Narrator: If you want
a sense of just how
strange lakes can be,
339
00:23:53,749 --> 00:23:57,334
The biggest lake in the world
is a good place to start.
340
00:24:01,774 --> 00:24:05,309
Lake baikal's own resident
water dragon tends to get
341
00:24:05,411 --> 00:24:09,280
Blamed whenever anything
unusual happens here,
342
00:24:10,249 --> 00:24:15,402
And in 2009, something
totally extraordinary happens.
343
00:24:20,309 --> 00:24:23,010
Astronauts aboard the
international space station
344
00:24:23,112 --> 00:24:25,579
Observe giant circles,
345
00:24:27,083 --> 00:24:30,334
Huge rings carved into the ice.
346
00:24:32,171 --> 00:24:35,239
They are over two and a
half miles in diameter.
347
00:24:37,376 --> 00:24:40,411
And so bizarre that it's
not just the water dragon
348
00:24:40,513 --> 00:24:42,446
That gets blamed.
349
00:24:46,235 --> 00:24:50,838
Alexei: People started to
speak about flying saucers,
350
00:24:52,008 --> 00:24:55,543
Fairy rings, or
underwater civilizations.
351
00:24:55,645 --> 00:24:58,445
So it looks so strange
and so unusual.
352
00:25:00,583 --> 00:25:04,301
Narrator: Alexei kouraev
is studying the circles
scientifically,
353
00:25:04,403 --> 00:25:07,571
Trying to work out
what causes them.
354
00:25:09,775 --> 00:25:13,344
Might what he discovers
shed light on those strange
355
00:25:13,446 --> 00:25:16,514
Sightings back in loch ness?
356
00:25:17,884 --> 00:25:21,569
The most obvious thing about
the rings close up are gas
357
00:25:21,671 --> 00:25:24,538
Bubbles trapped in the ice.
358
00:25:26,409 --> 00:25:29,610
At first, experts wonder
if this means the rings are
359
00:25:29,712 --> 00:25:33,480
Connected to giant underwater
gas vents that alexei knows
360
00:25:33,583 --> 00:25:35,866
Are on the lake bed.
361
00:25:40,206 --> 00:25:44,108
He sends a remotely
operated vehicle, or rov,
362
00:25:44,210 --> 00:25:48,212
Under the ice to see if the
bubbles and rings are linked.
363
00:25:49,982 --> 00:25:53,234
But deep in the lake, the
water's so dark it's almost
364
00:25:53,336 --> 00:25:56,370
Impossible for him
to see anything.
365
00:25:58,708 --> 00:26:01,375
But we can.
366
00:26:02,111 --> 00:26:06,046
Using the data from alexei's
rov to drain part of the lake
367
00:26:06,148 --> 00:26:09,500
That's known to contain vents.
368
00:26:12,705 --> 00:26:15,239
As vast volumes
of water vanish,
369
00:26:17,843 --> 00:26:21,645
The steep lake sides
plummet a mile down.
370
00:26:24,717 --> 00:26:27,735
And now, daylight shines
on the massive expanse
371
00:26:27,853 --> 00:26:30,804
Of the lake bed.
372
00:26:31,474 --> 00:26:35,376
Huge rocky cliffs travel
along its length, evidence of
373
00:26:35,478 --> 00:26:39,747
The giant seismic rift that
first created baikal.
374
00:26:41,584 --> 00:26:44,868
Near the rift, raised areas.
375
00:26:46,339 --> 00:26:49,340
The vents.
376
00:26:50,376 --> 00:26:53,277
These are mini volcanoes.
377
00:26:53,379 --> 00:26:57,247
Holes in the earth's crust
that spew out hot gasses
378
00:26:57,350 --> 00:27:00,334
Into the icy waters.
379
00:27:01,771 --> 00:27:04,204
But there's a further mystery,
380
00:27:04,307 --> 00:27:07,841
The sites of the vents
bear no relation
381
00:27:07,943 --> 00:27:10,744
To the sites
of the giant rings.
382
00:27:12,114 --> 00:27:14,782
So they can't be causing them.
383
00:27:23,242 --> 00:27:26,577
From the air, the surface
of this immense lake looks
384
00:27:26,679 --> 00:27:30,080
Utterly still and inert.
385
00:27:31,801 --> 00:27:35,969
But recent research by alexei
is showing that under the ice
386
00:27:36,072 --> 00:27:39,073
It's a different story.
387
00:27:41,077 --> 00:27:44,278
Alexei: Baikal is covered
for several months by ice.
388
00:27:44,380 --> 00:27:46,947
One may think that
it's sleeping,
389
00:27:47,049 --> 00:27:50,167
But actually it's
quite the opposite.
390
00:28:01,447 --> 00:28:04,515
So by cutting a
hole in the ice,
391
00:28:04,617 --> 00:28:08,936
It gives you a kind of window
to this underwater world.
392
00:28:19,582 --> 00:28:22,666
Narrator: Alexei is
sending down the rov,
393
00:28:22,768 --> 00:28:26,203
To study how water
behaves in baikal.
394
00:28:29,275 --> 00:28:34,611
As it descends, it monitors the
density and speed of currents,
395
00:28:34,714 --> 00:28:38,315
To create a three-dimensional
image of the water.
396
00:28:40,870 --> 00:28:44,171
His work has deepened our
knowledge of how lake baikal
397
00:28:44,273 --> 00:28:48,675
Actually works, revealing
that under the ice,
398
00:28:48,778 --> 00:28:51,612
The water is in turmoil.
399
00:28:51,714 --> 00:28:56,834
Alexei: So it's a huge mass of
water with several hundreds of
400
00:28:56,936 --> 00:29:01,171
Meter high, which is
in constant rotation.
401
00:29:03,642 --> 00:29:06,376
Narrator: As cold winds
blow over the lake,
402
00:29:06,479 --> 00:29:09,747
They chill the top
layers of water.
403
00:29:10,716 --> 00:29:16,203
These then sink and
warmer layers below rise,
404
00:29:16,305 --> 00:29:20,040
Creating immense currents
which eventually form
405
00:29:20,142 --> 00:29:23,544
Powerful spiraling eddies.
406
00:29:26,515 --> 00:29:28,215
Alexei: When you know
where the eddies,
407
00:29:28,317 --> 00:29:31,335
Most probably the ice
rinks will develop.
408
00:29:32,404 --> 00:29:34,972
Narrator: The eddies, with
their powerful columns of
409
00:29:35,074 --> 00:29:38,675
Warm water, corkscrew around...
410
00:29:40,246 --> 00:29:44,314
Thinning the ice above them
and forming great rings.
411
00:29:46,769 --> 00:29:51,472
So huge, they can
be seen from space.
412
00:29:57,646 --> 00:30:01,448
Could loch ness contain forces
just as strange and surprising
413
00:30:01,550 --> 00:30:04,501
As those in baikal?
414
00:30:05,971 --> 00:30:09,540
And if so, might they account
for some of the most common
415
00:30:09,642 --> 00:30:12,042
Monster sightings of all,
416
00:30:12,144 --> 00:30:15,145
The ones that swim
against the current.
417
00:30:16,649 --> 00:30:19,566
Woman: Oh my god, it's moving.
418
00:30:22,671 --> 00:30:25,138
Narrator: When the summer
sun heats the surface,
419
00:30:25,241 --> 00:30:28,141
It creates a thin layer of
warm water on top
420
00:30:28,244 --> 00:30:30,944
Of colder, denser
water underneath.
421
00:30:34,083 --> 00:30:37,634
When the wind blows, it
pushes that warmer layer
422
00:30:37,736 --> 00:30:40,037
Up the length of the loch.
423
00:30:41,173 --> 00:30:46,310
When it reaches the far end,
it bounces back down the loch,
424
00:30:46,412 --> 00:30:49,646
Moving in the opposite
direction to the cooler water
425
00:30:49,748 --> 00:30:52,366
Underneath it.
426
00:30:53,769 --> 00:30:57,304
Adrian: Invisible at the
surface, huge waves fall.
427
00:30:57,406 --> 00:31:00,073
They are very slow
but they are very big.
428
00:31:00,242 --> 00:31:02,743
They are over 100 feet high.
429
00:31:04,947 --> 00:31:09,366
Narrator: With invisible
waves rebounding up and
down the loch,
430
00:31:10,369 --> 00:31:13,370
Big objects carried
by the top layer,
431
00:31:13,472 --> 00:31:16,406
Create the illusion that
something is swimming
432
00:31:16,508 --> 00:31:19,443
Against the wind.
433
00:31:25,217 --> 00:31:28,569
Adrian: That is a perfectly
rational deduction,
434
00:31:28,671 --> 00:31:33,740
That a piece of material is
seen to have a slow motion
435
00:31:33,842 --> 00:31:39,146
Against the wind, and hence
thought to be swimming.
436
00:31:41,884 --> 00:31:44,368
Narrator: Scientists are
convinced this phenomenon can
437
00:31:44,470 --> 00:31:47,804
Explain malcolm irvine's
sighting of a creature
438
00:31:47,907 --> 00:31:51,275
Moving against the current.
439
00:31:54,380 --> 00:31:57,314
But there is still one
type of sighting that
440
00:31:57,416 --> 00:32:00,701
Remains unexplained.
441
00:32:01,637 --> 00:32:05,138
One of the most common of all.
442
00:32:08,777 --> 00:32:11,378
Many people have claimed to
see something that looks like
443
00:32:11,480 --> 00:32:16,333
A giant multi-humped creature,
wriggling across the loch.
444
00:32:22,141 --> 00:32:24,908
The first person to study
the monster seriously,
445
00:32:25,010 --> 00:32:28,145
Rupert gould, concluded from
these sightings that nessie
446
00:32:28,247 --> 00:32:30,981
Must be a sea serpent.
447
00:32:32,735 --> 00:32:37,070
So, are all the people who claim
to see this just deluded?
448
00:32:37,973 --> 00:32:41,108
Or could an extraordinary new
discovery by adrian and his
449
00:32:41,210 --> 00:32:46,213
Crew prove that they are seeing
something real after all?
450
00:32:54,006 --> 00:32:56,239
Narrator: Adrian and craig are
on the second part of their
451
00:32:56,342 --> 00:32:58,675
Mission to scan loch ness.
452
00:32:59,645 --> 00:33:03,213
This time, they're on the
hunt for a tragic shipwreck,
453
00:33:03,315 --> 00:33:06,400
Lost for almost 70 years.
454
00:33:11,640 --> 00:33:16,843
In 1952, national hero john
cobb is determined to attempt
455
00:33:16,945 --> 00:33:19,846
The world water speed record.
456
00:33:20,783 --> 00:33:22,432
Man (over film): He climbed
into the cockpit of a
457
00:33:22,534 --> 00:33:25,602
6,000 horsepower
hydroplane, the crusader.
458
00:33:25,704 --> 00:33:28,472
Loch ness in scotland, the
habitat of a legendary sea
459
00:33:28,574 --> 00:33:31,508
Serpent, had been chosen as
the ideal spot for the planned
460
00:33:31,610 --> 00:33:34,211
Record breaking time trial.
461
00:33:39,968 --> 00:33:42,002
Narrator: But as the jet
engine that powers his boat
462
00:33:42,104 --> 00:33:46,306
Pushes it over 200
miles per hour...
463
00:33:46,942 --> 00:33:48,875
Disaster.
464
00:33:55,801 --> 00:34:00,537
The crusader explodes and
john cobb is killed instantly.
465
00:34:04,243 --> 00:34:07,611
Only small pieces of
debris are ever recovered.
466
00:34:07,713 --> 00:34:10,047
Where is the rest of the boat
467
00:34:10,149 --> 00:34:13,133
And the giant engine
that powered it?
468
00:34:14,169 --> 00:34:17,204
And what caused the crash?
469
00:34:20,776 --> 00:34:25,378
Believers have long
speculated that the
monster could be to blame.
470
00:34:27,483 --> 00:34:30,634
The crash took place on the
eastern end of the loch,
471
00:34:30,736 --> 00:34:33,837
And it's here adrian
and craig will scan.
472
00:34:36,408 --> 00:34:40,143
It's not the first time adrian's
looked for the crusader.
473
00:34:45,150 --> 00:34:48,969
In July 2002, using the
remotely operated vehicle,
474
00:34:49,071 --> 00:34:52,539
His team finds what they
believe to be a debris field.
475
00:34:55,577 --> 00:35:00,614
But 700 feet down, visibility
is so poor there's no way of
476
00:35:00,783 --> 00:35:04,434
Knowing if this
really is cobb's boat.
477
00:35:09,441 --> 00:35:11,641
Now they're back.
478
00:35:12,644 --> 00:35:16,213
Using munin's advanced
scanning technology,
479
00:35:16,315 --> 00:35:21,268
To find out if this is
indeed the last resting
place of the crusader.
480
00:35:23,806 --> 00:35:25,872
Craig: So here is the
mission we planned,
481
00:35:25,974 --> 00:35:28,508
And you can see that this is
really tight line spacing,
482
00:35:28,610 --> 00:35:31,745
Giving us the best possible
chance of finding that engine.
483
00:35:31,847 --> 00:35:33,947
Adrian: It really is.
484
00:35:34,349 --> 00:35:36,299
Craig: We've dropped down
very close to the sea bed,
485
00:35:36,401 --> 00:35:38,301
So the size scanner is
running at 600 kilohertz.
486
00:35:38,403 --> 00:35:40,170
Adrian: 600, that's very high.
487
00:35:40,272 --> 00:35:43,507
Craig: And we're, so
it's the best possible
solution we can have.
488
00:35:45,644 --> 00:35:47,944
Narrator: Cruising
close to the crash site,
489
00:35:48,046 --> 00:35:50,947
The underwater robot
passes back and forth,
490
00:35:51,049 --> 00:35:54,034
Constantly scanning
whatever is below.
491
00:35:55,137 --> 00:35:57,470
With the data
successfully on board,
492
00:35:57,573 --> 00:36:00,273
The team analyzes the results.
493
00:36:00,776 --> 00:36:02,442
Craig: What I'm seeing is
something much larger than
494
00:36:02,544 --> 00:36:04,678
We previously thought.
495
00:36:04,780 --> 00:36:06,780
Something here
worth investigating.
496
00:36:06,882 --> 00:36:08,648
Adrian: There certainly is.
497
00:36:08,784 --> 00:36:10,000
Craig: Let's process
some of the data.
498
00:36:10,102 --> 00:36:12,235
So once it's processed,
what you get here,
499
00:36:12,337 --> 00:36:14,905
We can take a look at
this in three dimensions.
500
00:36:15,908 --> 00:36:19,442
So the same site
gives us this.
501
00:36:20,279 --> 00:36:21,945
Adrian: Oh well.
502
00:36:22,047 --> 00:36:27,200
That looks like crusader,
and I am amazed.
503
00:36:29,304 --> 00:36:31,638
Narrator: If they've
discovered the crusader,
504
00:36:31,740 --> 00:36:34,140
It could be
historically important,
505
00:36:34,243 --> 00:36:37,611
Revealing details of the
crash for the first time.
506
00:36:40,282 --> 00:36:44,100
To be sure, we need to remove
the dark waters of loch ness
507
00:36:44,203 --> 00:36:47,604
From above the wreck.
508
00:36:50,609 --> 00:36:54,444
As the loch empties,
a remarkable sight.
509
00:36:57,316 --> 00:36:59,766
The debris field.
510
00:37:01,236 --> 00:37:06,740
Scattered pieces of aluminum
blown apart by explosive power.
511
00:37:09,878 --> 00:37:13,847
As light hits what appears to
be the broken aluminum hull,
512
00:37:15,183 --> 00:37:19,536
It's clear half the
boat remains intact.
513
00:37:20,806 --> 00:37:24,207
Including one of
its stabilizers.
514
00:37:26,111 --> 00:37:31,081
And a huge jet engine runs over
a third the length of the boat,
515
00:37:32,301 --> 00:37:36,569
Much bigger than you'd expect
on any regular speed boat.
516
00:37:38,974 --> 00:37:41,975
It's the proof they've
been looking for.
517
00:37:42,344 --> 00:37:44,611
It's the crusader.
518
00:37:45,981 --> 00:37:51,501
But can they solve the
mystery of why it was wrecked?
519
00:37:51,603 --> 00:37:54,571
And why some people
believe that nessie
520
00:37:54,673 --> 00:37:57,040
Could have played a role.
521
00:37:58,277 --> 00:38:01,411
Adrian: After the accident,
there were speculations that
522
00:38:01,513 --> 00:38:04,581
It was the wake of
the loch ness monster.
523
00:38:07,235 --> 00:38:09,903
Narrator: Adrian and craig go
back to the original footage
524
00:38:10,005 --> 00:38:13,406
And analyze the
crash frame by frame.
525
00:38:19,614 --> 00:38:22,799
And spot something unusual.
526
00:38:24,169 --> 00:38:25,735
Adrian: That's interesting.
527
00:38:25,837 --> 00:38:28,571
I think we should look
at the other side, yes.
528
00:38:28,674 --> 00:38:30,440
Right.
529
00:38:30,542 --> 00:38:33,143
Now this is different.
530
00:38:33,245 --> 00:38:35,178
Craig: This is from
the other side, looking
from the west shore.
531
00:38:35,280 --> 00:38:37,480
Adrian: There is an
oscillation taking place.
532
00:38:37,582 --> 00:38:38,782
Craig: Yeah.
533
00:38:38,884 --> 00:38:39,833
Adrian: He's thrown
backwards and forwards,
534
00:38:39,935 --> 00:38:41,601
Backwards and forwards.
535
00:38:41,703 --> 00:38:44,604
Craig: So she's still fully
in control as she crosses the
536
00:38:44,706 --> 00:38:45,872
Measure mile.
537
00:38:45,974 --> 00:38:49,376
Adrian: She's in control,
but she's oscillating.
538
00:38:50,712 --> 00:38:51,845
Craig: He's started
to slow down,
539
00:38:51,947 --> 00:38:54,347
The camera's slowly
catching there.
540
00:38:54,449 --> 00:38:58,134
Adrian: And down goes the bow
and immediately you see this
541
00:38:58,236 --> 00:39:00,437
Plume go out.
542
00:39:00,539 --> 00:39:02,472
Craig: Yeah.
543
00:39:02,574 --> 00:39:05,275
Adrian: And there we go.
544
00:39:08,547 --> 00:39:12,565
Narrator: Analysis of
the footage reveals
crusader hits waves.
545
00:39:12,667 --> 00:39:14,834
But this is puzzling.
546
00:39:14,936 --> 00:39:18,038
There shouldn't
have been any waves.
547
00:39:20,042 --> 00:39:23,643
Cobb and his team know that
they can only conduct speed
548
00:39:23,745 --> 00:39:28,248
Trials on those rare days when
the loch is absolutely calm.
549
00:39:29,451 --> 00:39:32,702
They delay their record-breaking
attempt until the wind
550
00:39:32,804 --> 00:39:36,506
Has dropped and the loch is
so calm it's like a mirror.
551
00:39:38,076 --> 00:39:42,112
So where does the
mysterious wave come from?
552
00:39:47,769 --> 00:39:49,969
Adrian thinks there's
something else on the bottom
553
00:39:50,072 --> 00:39:53,339
Of the loch that could help
answer the question of why
554
00:39:53,442 --> 00:39:57,077
Waves big enough to destroy
a boat can suddenly appear in
555
00:39:57,179 --> 00:40:00,880
Loch ness, as if from nowhere.
556
00:40:13,111 --> 00:40:16,196
Narrator: People have lived
around loch ness for centuries.
557
00:40:17,549 --> 00:40:20,533
But there were hardly any
sightings of a monster until
558
00:40:20,635 --> 00:40:24,838
The 1930s, when the
numbers explode.
559
00:40:26,141 --> 00:40:28,875
Why the sudden increase?
560
00:40:30,445 --> 00:40:33,613
Adrian believes that
another wreck at the
bottom of loch ness
561
00:40:33,715 --> 00:40:37,300
May help explain,
and shed light on
562
00:40:37,402 --> 00:40:41,004
The tragic fate of john cobb.
563
00:40:45,677 --> 00:40:49,279
The pansy is an
ocean-going fishing boat,
564
00:40:49,381 --> 00:40:52,415
Built at the turn
of the 20th century.
565
00:40:52,501 --> 00:40:57,737
She has a 60 foot main mast,
two feet thick at the base.
566
00:40:58,940 --> 00:41:04,043
But what is an ocean-going
vessel doing in loch ness?
567
00:41:07,449 --> 00:41:12,202
In 1803, construction begins
on an ambitious project to
568
00:41:12,304 --> 00:41:16,439
Link the lochs of the great
glen into a 60 mile passage
569
00:41:16,541 --> 00:41:18,975
From sea to sea.
570
00:41:19,077 --> 00:41:22,278
The caledonian canal.
571
00:41:27,135 --> 00:41:30,303
With this waterway in place,
fishing fleets can now cross
572
00:41:30,405 --> 00:41:34,774
Through its canal locks
quickly from one side of
scotland to the other.
573
00:41:35,277 --> 00:41:38,044
Adrian: Thousands once moved
through loch ness from the
574
00:41:38,180 --> 00:41:40,914
East to the west
coast fishing grounds.
575
00:41:42,017 --> 00:41:45,468
Narrator: One of those thousands
of boats is the pansy.
576
00:41:46,438 --> 00:41:51,140
Perhaps it can now offer
up a clue to the surge
in monster sightings.
577
00:41:54,312 --> 00:41:56,579
Craig: So, we're gonna pass
the munin really close right
578
00:41:56,681 --> 00:41:59,082
Over the top of pansy, so
we can get the best possible
579
00:41:59,184 --> 00:42:01,768
Three-dimensional
representation of the wreck.
580
00:42:03,371 --> 00:42:05,772
Narrator: The pansy sinks
near the center of the loch,
581
00:42:05,874 --> 00:42:08,908
Close to an area
called foyers.
582
00:42:09,711 --> 00:42:13,680
It's here where munin is
completing its final scan.
583
00:42:16,434 --> 00:42:19,335
Craig: If we zoom in
here, wow, look at that.
584
00:42:19,437 --> 00:42:21,137
Now I'm starting to
see some extra footage.
585
00:42:21,239 --> 00:42:23,106
Adrian: You have the
most classic form.
586
00:42:23,241 --> 00:42:26,409
Look at that deep four foot
and that digs into the water
587
00:42:26,511 --> 00:42:29,913
And allows the vessel to
tack against the wind.
588
00:42:30,382 --> 00:42:34,234
Look at the rudder there
on that sharp stern.
589
00:42:36,238 --> 00:42:39,556
Narrator: Using craig's
incredibly precise data,
590
00:42:39,641 --> 00:42:42,709
We can drain the waters
around the wreck of pansy,
591
00:42:42,811 --> 00:42:46,813
To show the loch bed here
in extraordinary detail.
592
00:42:48,583 --> 00:42:53,202
Revealing the fishing
boat for the first time
in almost 100 years.
593
00:42:58,543 --> 00:43:03,413
Gently resting on the loch
bed, she's remarkably intact.
594
00:43:05,417 --> 00:43:09,469
Including the crutch on which
the huge mast once rested.
595
00:43:10,538 --> 00:43:14,540
But the data reveals
something unexpected.
596
00:43:14,643 --> 00:43:17,377
A missing piece.
597
00:43:17,912 --> 00:43:19,379
Adrian: Where's the mast?
Craig: Yeah.
598
00:43:19,481 --> 00:43:21,914
Adrian: If there's no mast
then how did she get about?
599
00:43:22,017 --> 00:43:23,700
Craig: Yep.
600
00:43:24,269 --> 00:43:28,304
Narrator: Returning to
the drained wreck site
reveals the answer.
601
00:43:29,641 --> 00:43:33,710
Inside her wooden
hull, an engine.
602
00:43:34,980 --> 00:43:38,881
Adrian: The boat was built
in 1903, but in 1909,
603
00:43:38,984 --> 00:43:42,068
An auxiliary motor was fitted.
604
00:43:42,170 --> 00:43:45,705
A 40... A 48 horsepower
thornycroft.
605
00:43:47,375 --> 00:43:50,043
Narrator: Pansy didn't
have a mast because she
606
00:43:50,145 --> 00:43:52,745
No longer needed one.
607
00:43:52,847 --> 00:43:55,882
The installing of a
thornycroft engine allowed
608
00:43:55,950 --> 00:43:58,334
Her to move between
fishing grounds,
609
00:43:58,436 --> 00:44:01,070
Even in dead calm weather.
610
00:44:02,207 --> 00:44:05,642
And this simple advance in
technology may help explain
611
00:44:05,744 --> 00:44:09,245
How a wave could suddenly
come from nowhere,
612
00:44:09,347 --> 00:44:12,699
As it did so disastrously
for john cobb.
613
00:44:15,603 --> 00:44:17,437
Adrian: If the
water goes calm,
614
00:44:17,539 --> 00:44:22,041
A sailing vessel goes
nowhere, it is becalmed.
615
00:44:23,812 --> 00:44:27,647
Narrator: To be able to sail,
a sailing vessel requires wind,
616
00:44:27,749 --> 00:44:31,000
And wind can disturb the
water so completely you
617
00:44:31,102 --> 00:44:33,736
Can't see a boat's wake.
618
00:44:33,838 --> 00:44:36,739
But with the advent
of motor power,
619
00:44:36,841 --> 00:44:40,043
Boats can travel back and
forth across loch ness,
620
00:44:40,145 --> 00:44:42,311
In dead calm,
621
00:44:42,447 --> 00:44:46,399
Leaving an unbroken and
visible wake behind them.
622
00:44:48,803 --> 00:44:52,338
It's now that loch ness
itself turns these wakes into
623
00:44:52,440 --> 00:44:55,174
Something remarkable.
624
00:44:55,643 --> 00:44:59,946
Its steep sides and unusually
straight shape mean that wakes
625
00:45:00,115 --> 00:45:03,032
Created by boats
can last for hours,
626
00:45:03,134 --> 00:45:08,371
Moving up and down the loch,
miles from any visible boat.
627
00:45:10,375 --> 00:45:12,075
Adrian: If you're
looking across the loch,
628
00:45:12,177 --> 00:45:16,345
The vessel having made it
will have gone a mile or more
629
00:45:16,448 --> 00:45:19,715
Before that, that
wake hits the shore.
630
00:45:21,403 --> 00:45:24,470
Narrator: Despite
cobb's precautions,
631
00:45:24,572 --> 00:45:27,974
The likely explanation for
his crash is that his lightly
632
00:45:28,076 --> 00:45:32,111
Built speed boat hit
a long lasting wake,
633
00:45:32,213 --> 00:45:36,199
Perhaps from one of his
own support vessels.
634
00:45:37,535 --> 00:45:40,136
Adrian: They can travel
for miles in calm water,
635
00:45:40,238 --> 00:45:42,138
Where they're not broken up.
636
00:45:42,240 --> 00:45:45,942
At 200 miles an hour, any
wave is going to damage a
637
00:45:46,044 --> 00:45:48,911
Lightly built vessel
like crusader.
638
00:45:50,915 --> 00:45:53,399
Narrator: The unexpectedly
strange behavior of water and
639
00:45:53,501 --> 00:45:58,538
Currents in loch ness may also
explain that strangest of all
640
00:45:58,640 --> 00:46:02,675
Phenomena in the
loch, the monster.
641
00:46:04,362 --> 00:46:08,014
From above, they
are simple wakes.
642
00:46:08,116 --> 00:46:12,902
But side on from the shore
line, the monster appears.
643
00:46:15,173 --> 00:46:18,174
Adrian: And that wake,
observed from a low angle,
644
00:46:18,276 --> 00:46:20,777
Actually looks very solid.
645
00:46:21,412 --> 00:46:23,012
Man: See, look, what's that?
646
00:46:23,114 --> 00:46:25,281
What is that?
647
00:46:25,383 --> 00:46:28,935
Narrator: Just as cobb's vessel
was likely hit by a wake,
648
00:46:29,003 --> 00:46:32,171
The many people who think
they see a humped serpent
649
00:46:32,273 --> 00:46:33,940
Wriggling in the loch
650
00:46:34,042 --> 00:46:37,376
May in fact be seeing
nothing more mysterious
651
00:46:37,479 --> 00:46:42,048
Than the watery signature of
a boat that's many miles away.
652
00:46:42,867 --> 00:46:45,802
Adrian: Have we solved
the loch ness mystery?
653
00:46:46,704 --> 00:46:52,074
Well, there will be a loch ness
monster as long as we want one.
654
00:46:54,946 --> 00:46:58,181
Narrator: Draining loch ness
reveals a possible scientific
655
00:46:58,283 --> 00:47:02,034
Explanation of one of the
world's greatest mysteries.
656
00:47:04,272 --> 00:47:08,674
But for the excited visitors who
still come in search of nessie,
657
00:47:09,644 --> 00:47:13,346
And the hundreds who
claim to catch a glimpse of her,
658
00:47:13,448 --> 00:47:17,433
The monster remains
alive and well.
