Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:02,585 --> 00:00:04,504
The Ocean....
2
00:00:04,587 --> 00:00:06,089
the last frontier on earth.
3
00:00:06,923 --> 00:00:10,468
{\an8}So much is unexplored
and unexplained.
4
00:00:10,677 --> 00:00:11,803
{\an8}To change that...
5
00:00:12,387 --> 00:00:15,473
a kickass team of insanely
talented specialists is
6
00:00:15,598 --> 00:00:18,226
setting out to push the
frontiers of what we know
7
00:00:18,309 --> 00:00:20,603
about our oceans.
8
00:00:22,355 --> 00:00:23,648
Oh my gosh.
9
00:00:23,732 --> 00:00:27,068
Zoleka Filander,
deep sea scientist.
10
00:00:27,152 --> 00:00:28,987
Being a
deep sea researcher means
11
00:00:29,070 --> 00:00:32,866
having front row tickets to
the best movie that everybody
12
00:00:32,949 --> 00:00:34,492
wants to watch.
13
00:00:34,576 --> 00:00:35,869
Melissa Márquez...
14
00:00:35,952 --> 00:00:37,287
Straight ahead, 12:00.
15
00:00:37,370 --> 00:00:38,705
Shark biologist.
16
00:00:38,788 --> 00:00:41,666
We just saw
what no one has seen before.
17
00:00:41,750 --> 00:00:43,626
Eric Stackpole...
18
00:00:43,710 --> 00:00:44,794
Scan now!
19
00:00:44,878 --> 00:00:46,087
Ocean tech innovator.
20
00:00:46,171 --> 00:00:47,922
I love
building tools that allow us
21
00:00:48,006 --> 00:00:50,550
to see things in ways
we've never seen before.
22
00:00:51,926 --> 00:00:53,386
And Aldo Kane...
23
00:00:54,220 --> 00:00:55,764
This is insane.
24
00:00:55,847 --> 00:00:58,058
Former
Royal Marine; special ops.
25
00:00:58,141 --> 00:01:00,560
It doesn't
get any more cutting-edge
26
00:01:00,643 --> 00:01:02,312
exploration than this.
27
00:01:02,395 --> 00:01:05,065
Their secret weapon...
28
00:01:05,148 --> 00:01:07,650
...the OceanXplorer.
29
00:01:09,861 --> 00:01:12,113
The most technologically
advanced research vessel
30
00:01:12,197 --> 00:01:14,866
ever built.
31
00:01:15,408 --> 00:01:17,744
There's never been a more
urgent need to understand
32
00:01:17,827 --> 00:01:21,748
our ocean and the
animals that call it home...
33
00:01:22,499 --> 00:01:27,003
Because their lives
and ours depend on it.
34
00:01:28,463 --> 00:01:30,757
Okay
here we go. 2:00, 2:00.
35
00:01:30,840 --> 00:01:33,259
This time
the team track sperm whales,
36
00:01:33,343 --> 00:01:35,345
down into an alien world.
37
00:01:35,428 --> 00:01:36,930
What is that?
38
00:01:37,013 --> 00:01:39,224
Full
of fantastical creatures.
39
00:01:40,642 --> 00:01:42,811
No, ho, oh!
40
00:01:42,894 --> 00:01:47,941
{\an8}.
41
00:01:50,735 --> 00:01:53,947
The OceanXplorer
is heading for deep water.
42
00:01:56,074 --> 00:01:58,409
Just off the Azores.
43
00:01:58,868 --> 00:02:03,039
{\an8}A chain of tiny volcanic islands
in the middle of the Atlantic.
44
00:02:06,626 --> 00:02:11,131
And a rich oasis for an
abundance of marine life.
45
00:02:23,726 --> 00:02:27,522
{\an8}Every summer nearly
1,000 sperm whales gather here.
46
00:02:31,860 --> 00:02:33,444
They're easily identified by
47
00:02:33,528 --> 00:02:36,406
their distinctive
sideways spout.
48
00:02:43,163 --> 00:02:47,083
These whales spend most of their
lives deep below the surface.
49
00:02:49,752 --> 00:02:52,755
But using the full scope
of the OceanXplorer's tech,
50
00:02:53,256 --> 00:02:56,259
the team hopes to shine a
light on their lives down
51
00:02:56,342 --> 00:02:58,595
in these black depths.
52
00:03:05,768 --> 00:03:07,604
Standby 9:00.
53
00:03:17,947 --> 00:03:19,866
Sperm whales
were hunted here as recently as
54
00:03:19,949 --> 00:03:23,453
1987 and they
live up to 70 years,
55
00:03:23,536 --> 00:03:25,997
so some of them may
still remember that.
56
00:03:27,207 --> 00:03:30,668
They're understandably
nervous around boats.
57
00:03:31,377 --> 00:03:34,380
So Aldo and Melissa
approach cautiously.
58
00:03:44,182 --> 00:03:46,684
{\an8}You
got your eyes on them?
59
00:03:47,518 --> 00:03:49,687
{\an8}They're sneaky I tell 'ya.
60
00:03:56,903 --> 00:03:58,321
Oh my God, they're
right underneath us.
61
00:03:58,404 --> 00:04:00,031
They're right underneath us.
62
00:04:07,038 --> 00:04:09,249
{\an8}Wow, look at that.
63
00:04:10,500 --> 00:04:12,919
It's a whole family pod.
64
00:04:14,712 --> 00:04:16,923
That's gorgeous.
65
00:04:23,554 --> 00:04:25,306
That
is a first for me.
66
00:04:25,390 --> 00:04:26,933
Yeah!
67
00:04:28,434 --> 00:04:31,729
Sperm whales
are the largest toothed predator
68
00:04:31,813 --> 00:04:33,731
on the planet.
69
00:04:37,318 --> 00:04:39,904
To study these giants
up close and personal
70
00:04:39,988 --> 00:04:43,283
Aldo and Melissa join
them beneath the waves.
71
00:04:51,249 --> 00:04:52,417
Getting under the water and
72
00:04:52,500 --> 00:04:55,753
just seeing this giant animal,
73
00:04:56,963 --> 00:05:00,300
you can feel it looking at you,
74
00:05:01,342 --> 00:05:04,304
trying to figure out
what the heck you are.
75
00:05:07,056 --> 00:05:08,683
But
they won't have long.
76
00:05:12,645 --> 00:05:16,232
Sperm whales spend just 20%
of their lives at the surface.
77
00:05:24,949 --> 00:05:28,161
When
they dive, it's phenomenal.
78
00:05:31,831 --> 00:05:36,085
One swoosh of their
tail and they are gone.
79
00:05:44,344 --> 00:05:46,262
These whales
are diving a mile deep for up
80
00:05:46,346 --> 00:05:48,264
to an hour at a time.
81
00:05:49,057 --> 00:05:51,976
The buoyancy of their huge
lungs and the thick blubber
82
00:05:52,060 --> 00:05:54,604
should make that
almost impossible,
83
00:05:54,687 --> 00:05:58,191
but not only do they manage it
they make it look effortless.
84
00:06:05,907 --> 00:06:09,827
But exactly how they dive
so deep has never been filmed.
85
00:06:14,749 --> 00:06:17,877
If the team can get
a camera on a whale it
86
00:06:17,960 --> 00:06:19,629
could further
their understanding.
87
00:06:22,882 --> 00:06:25,927
{\an8}They recruit the
help of Rui Prieto.
88
00:06:26,677 --> 00:06:28,471
A world leading whale biologist,
89
00:06:28,554 --> 00:06:32,100
he's been studying them in
the Azores for over 20 years.
90
00:06:35,103 --> 00:06:38,231
We want to see what
they are actually doing, uh,
91
00:06:38,481 --> 00:06:40,400
while they are underwater.
92
00:06:41,567 --> 00:06:43,236
Eric sets
to work helping Rui build
93
00:06:43,528 --> 00:06:46,489
{\an8}a camera tag that can
withstand the immense pressure
94
00:06:46,572 --> 00:06:48,741
{\an8}of a sperm whale dive.
95
00:06:49,617 --> 00:06:53,454
Okay, so this
is the power system and then,
96
00:06:53,538 --> 00:06:54,872
we've just got
the little camera.
97
00:06:54,956 --> 00:06:56,958
You know, the whole thing
looks pretty simple but I mean
98
00:06:57,041 --> 00:06:58,668
the thing that keeps going
through my mind is, you know,
99
00:06:58,751 --> 00:07:02,171
we're gonna have, you know,
maybe one window and one chance
100
00:07:02,255 --> 00:07:04,173
of putting this
together the right way.
101
00:07:04,257 --> 00:07:06,801
So do you think
that's something we can do?
102
00:07:06,884 --> 00:07:08,177
Fingers crossed, right?
103
00:07:08,302 --> 00:07:09,887
I guess we'll find out.
104
00:07:11,305 --> 00:07:12,390
If
they can pull this off,
105
00:07:12,598 --> 00:07:14,475
they'll get the
first ever footage
106
00:07:14,725 --> 00:07:17,186
of a deep sperm whale
dive in the Azores.
107
00:07:22,191 --> 00:07:23,860
- Can you swing it?
- Yeah.
108
00:07:24,193 --> 00:07:27,280
Let's turn
a whale into a cameraman.
109
00:07:29,115 --> 00:07:30,700
You have a green light.
110
00:07:30,783 --> 00:07:31,868
Copy green light.
111
00:07:31,951 --> 00:07:33,578
Green deck we're off.
112
00:07:37,915 --> 00:07:40,376
We need to
start looking for blows, okay?
113
00:07:40,460 --> 00:07:42,170
- Yeah.
- Yeah.
114
00:07:48,092 --> 00:07:49,427
Oh looks
like there could be
115
00:07:49,552 --> 00:07:50,970
something over there.
116
00:07:51,596 --> 00:07:54,640
Four, five, six,
seven, eight, nine, ten.
117
00:07:54,724 --> 00:07:56,601
I count 11 whales here.
118
00:07:56,893 --> 00:07:59,187
All in a tight cluster.
119
00:07:59,270 --> 00:08:00,396
Okay, here we go.
120
00:08:00,480 --> 00:08:02,982
2:00, 2:00, you should
have a pretty good eye.
121
00:08:03,065 --> 00:08:05,067
300-400 meters.
122
00:08:09,363 --> 00:08:10,990
Breaching.
123
00:08:12,909 --> 00:08:14,952
No, ho, oh!
124
00:08:16,162 --> 00:08:17,622
We think breaching
might be a form of
125
00:08:17,705 --> 00:08:20,082
communication between
a sperm whale family,
126
00:08:20,166 --> 00:08:22,627
however sometimes it might just
be the teenagers fooling around
127
00:08:22,710 --> 00:08:25,087
and you know,
blowing off some steam.
128
00:08:27,632 --> 00:08:30,718
Let's
go there very slowly.
129
00:08:30,801 --> 00:08:33,804
Slow and steady wins the race.
130
00:08:34,639 --> 00:08:35,973
Is that speed okay?
131
00:08:36,057 --> 00:08:37,517
Need to gain
a little bit on them because
132
00:08:37,600 --> 00:08:39,435
they are almost diving.
133
00:08:39,519 --> 00:08:42,230
When you're piloting
a boat this close to whales,
134
00:08:42,313 --> 00:08:45,274
there's absolutely
no room for error!
135
00:08:45,358 --> 00:08:47,276
You're dealing
with a live animal.
136
00:08:47,360 --> 00:08:50,821
So the whole thing
has to be 110% perfect
137
00:08:50,905 --> 00:08:52,823
or it's an aborted mission.
138
00:08:55,451 --> 00:08:57,161
That's it.
139
00:09:04,293 --> 00:09:06,837
- Well done.
- Well done dude. Tag on.
140
00:09:08,047 --> 00:09:10,341
OceanXplorer
this is Eagle Ray over.
141
00:09:10,424 --> 00:09:11,592
Eagle Ray, OceanXplorer.
142
00:09:11,676 --> 00:09:13,386
Go ahead.
143
00:09:13,469 --> 00:09:17,265
Tag deployed and we
will mark location on the GPS.
144
00:09:17,348 --> 00:09:19,350
Copy that. Nice work!
145
00:09:21,602 --> 00:09:23,187
The tag
is designed to release after
146
00:09:23,271 --> 00:09:27,900
eight hours, and send a signal
to help the team locate it,
147
00:09:27,984 --> 00:09:30,528
somewhere in the
middle of the Atlantic.
148
00:09:34,574 --> 00:09:36,784
It is
an intense feeling to spend
149
00:09:36,867 --> 00:09:39,870
all this time on something
and then watch it just go into
150
00:09:39,954 --> 00:09:42,456
the abyss on the
back of a whale.
151
00:09:48,212 --> 00:09:50,590
Oh what's this
directly in front of us?
152
00:09:52,758 --> 00:09:55,886
Confirm you
have visual on the tag?
153
00:09:55,970 --> 00:09:57,555
Affirmative
we're looking at something
154
00:09:57,638 --> 00:09:59,807
orange in the water,
it could be the tag.
155
00:10:00,808 --> 00:10:01,851
Roger that...
156
00:10:01,934 --> 00:10:04,895
We are making our way to
your location now, over.
157
00:10:06,814 --> 00:10:08,274
Oh I see it!
158
00:10:08,357 --> 00:10:10,026
We have
visual on the tag.
159
00:10:13,446 --> 00:10:14,989
Little bit more Aldo.
160
00:10:15,072 --> 00:10:16,782
Yeah, there you go. Right there.
161
00:10:16,866 --> 00:10:19,076
- You got it? Heavy.
- Yep got it.
162
00:10:22,663 --> 00:10:25,333
I'm dying to
know. How does the tag look?
163
00:10:25,416 --> 00:10:27,335
The tag does
look in good condition and
164
00:10:27,418 --> 00:10:29,462
the camera looks
like it is still dry.
165
00:10:29,545 --> 00:10:30,671
Yes!
166
00:10:30,755 --> 00:10:33,049
All right, great job guys.
167
00:10:39,263 --> 00:10:40,556
Should I cut this?
168
00:10:40,640 --> 00:10:42,099
Yes, please.
169
00:10:42,183 --> 00:10:46,354
Now, it could be some water
inside so we need to be careful.
170
00:10:46,854 --> 00:10:49,732
Very slowly. Very carefully.
171
00:10:49,940 --> 00:10:51,442
I'm like,
excited and nervous
172
00:10:51,525 --> 00:10:52,735
at the same time, you know,
173
00:10:52,818 --> 00:10:54,278
like did everything
work properly?
174
00:10:54,362 --> 00:10:55,446
Did the batteries last?
175
00:10:55,529 --> 00:10:57,198
Yes. Yes.
176
00:10:57,281 --> 00:10:58,616
- Got it?
- Take it off.
177
00:10:59,575 --> 00:11:01,369
It's dry. Okay.
178
00:11:01,452 --> 00:11:03,037
And
then there's our SD card.
179
00:11:03,287 --> 00:11:04,872
- You got it?
- I, I got it.
180
00:11:04,955 --> 00:11:06,207
This is it.
181
00:11:06,499 --> 00:11:09,627
This is what we've been
working all this time for.
182
00:11:09,710 --> 00:11:12,046
Let's plug this to
the computer and see.
183
00:11:12,129 --> 00:11:13,172
- Okay, yeah.
- Okay.
184
00:11:15,841 --> 00:11:19,095
Anything that
comes off this thing is new.
185
00:11:24,475 --> 00:11:25,726
Oh my God!
186
00:11:31,148 --> 00:11:33,776
That's the, the
blowhole and it's going down
187
00:11:33,859 --> 00:11:36,612
because it's,
it's getting darker.
188
00:11:37,446 --> 00:11:38,739
As
they dive, sperm whales
189
00:11:38,823 --> 00:11:41,450
undergo an
incredible transformation.
190
00:11:43,911 --> 00:11:46,622
The pressure of the water
compresses their lungs and
191
00:11:46,706 --> 00:11:48,624
with less volume inside,
192
00:11:48,708 --> 00:11:50,918
they become less buoyant,
193
00:11:51,001 --> 00:11:54,505
allowing them to dive
faster with minimum effort.
194
00:11:56,799 --> 00:11:59,385
As she dives faster, the
force of the water pushes
195
00:11:59,468 --> 00:12:01,554
the camera sideways.
196
00:12:03,389 --> 00:12:06,934
At 450 feet it flips.
197
00:12:08,352 --> 00:12:11,272
- It's pointing backward?
- Yes, it's pointing backwards.
198
00:12:12,064 --> 00:12:15,943
We can
actually see the flukes beating.
199
00:12:18,821 --> 00:12:21,282
Eric and Rui
are the first people ever to see
200
00:12:21,365 --> 00:12:24,744
a sperm whale use its
body and tail flukes to dive
201
00:12:24,827 --> 00:12:26,704
into the deep.
202
00:12:27,747 --> 00:12:29,790
I'm learning a
lot about how they actually
203
00:12:29,874 --> 00:12:32,835
flex their, their flukes.
204
00:12:32,918 --> 00:12:35,838
It's very slow. It's very calm.
205
00:12:40,718 --> 00:12:44,972
Then at 900 feet
the whale's behavior changes.
206
00:12:46,140 --> 00:12:47,558
Look,
the tail's stopped moving.
207
00:12:47,641 --> 00:12:49,560
Yeah it's,
it, it's called gliding.
208
00:12:49,643 --> 00:12:52,438
They use the, the, the
momentum that they have
209
00:12:52,521 --> 00:12:54,482
to glide and keep energy.
210
00:12:54,565 --> 00:12:56,650
- I see.
- And I've, I've never seen it.
211
00:12:56,734 --> 00:12:59,695
So it,
it, it's just amazing.
212
00:13:02,281 --> 00:13:03,741
Its tail
may have stopped moving but
213
00:13:03,824 --> 00:13:06,118
this whale is still diving.
214
00:13:08,037 --> 00:13:09,914
With gravity doing the work,
215
00:13:09,997 --> 00:13:13,250
it can save energy and
preserve precious oxygen.
216
00:13:18,297 --> 00:13:19,381
Listen.
217
00:13:21,258 --> 00:13:22,760
It's hunting.
This is the hunting sound.
218
00:13:22,843 --> 00:13:24,345
Yeah.
219
00:13:25,805 --> 00:13:28,474
Sperm whales
use sound to hunt in the dark.
220
00:13:31,977 --> 00:13:35,564
When their sonar clicks
hit an object and bounce back,
221
00:13:35,648 --> 00:13:38,442
the whale can locate a
target over a mile away.
222
00:13:47,451 --> 00:13:48,869
It's getting
lighter in the background
223
00:13:48,953 --> 00:13:50,079
you notice that?
224
00:13:50,162 --> 00:13:52,081
Yeah. Yeah. The,
the water is becoming clearer.
225
00:13:52,164 --> 00:13:53,791
No luck this time,
226
00:13:53,874 --> 00:13:57,086
so the whale begins its
journey back to the surface.
227
00:14:02,424 --> 00:14:03,551
I hear a different,
228
00:14:03,634 --> 00:14:04,969
a slightly higher
pitched clicking.
229
00:14:05,052 --> 00:14:06,595
Yes. It was a coda.
230
00:14:09,348 --> 00:14:10,850
It's
communicating with its family
231
00:14:10,933 --> 00:14:13,269
just like morse code for whales!
232
00:14:16,021 --> 00:14:17,314
Another one.
233
00:14:17,398 --> 00:14:19,900
Someone is answering.
234
00:14:20,526 --> 00:14:23,153
Each family
unit has a unique, "Coda,"
235
00:14:23,237 --> 00:14:25,531
that can be heard
from up to two miles away.
236
00:14:26,740 --> 00:14:29,785
- Wow, two, two! Two.
- Two! Another one!
237
00:14:31,245 --> 00:14:33,539
This is how
a surfacing whale reconnects
238
00:14:33,622 --> 00:14:35,624
with its family.
239
00:14:38,544 --> 00:14:40,004
So
you hear the coda's,
240
00:14:40,087 --> 00:14:41,422
and then the other one comes in.
241
00:14:41,505 --> 00:14:43,591
Yeah. Yeah.
Do we know that they do this?
242
00:14:43,674 --> 00:14:47,052
We know that they
talk to each other using codas,
243
00:14:47,136 --> 00:14:50,097
but I've never seen
them come together.
244
00:14:58,939 --> 00:15:01,859
Oh! I
can't believe we got this all.
245
00:15:07,990 --> 00:15:11,076
They are
completely interacting.
246
00:15:15,372 --> 00:15:18,626
Nothing like that
has ever been filmed.
247
00:15:22,796 --> 00:15:25,007
It's just amazing.
248
00:15:31,555 --> 00:15:33,265
We're
seeing something that has
249
00:15:33,349 --> 00:15:35,517
never been seen before.
250
00:15:35,601 --> 00:15:38,687
These huge whales, going to a
part of the world that we know
251
00:15:38,771 --> 00:15:41,941
almost nothing about and
we get a first person view.
252
00:15:42,024 --> 00:15:45,152
I'm right next to Rui and he's
spent his entire life trying to
253
00:15:45,527 --> 00:15:47,196
understand these animals
and this is something
254
00:15:47,321 --> 00:15:49,031
he's never seen before.
255
00:16:10,928 --> 00:16:13,013
Once back at
the surface some sperm whales
256
00:16:13,097 --> 00:16:15,724
spend their time socializing.
257
00:16:22,189 --> 00:16:25,109
Re-establishing family bonds.
258
00:16:39,540 --> 00:16:43,085
Others grab a quick power nap.
259
00:16:54,555 --> 00:16:57,558
But their time
together is brief.
260
00:17:01,937 --> 00:17:04,857
After just 15 minutes,
they'll dive again,
261
00:17:04,940 --> 00:17:08,610
in their
never-ending pursuit of prey.
262
00:17:17,661 --> 00:17:21,665
Sperm whales eat up
to a ton of squid a day.
263
00:17:23,751 --> 00:17:26,462
And with nearly
1,000 sperm whales here,
264
00:17:26,545 --> 00:17:28,964
that's a lot of squid.
265
00:17:31,133 --> 00:17:34,136
So what kind of squid are
hiding down there in the depths
266
00:17:34,219 --> 00:17:37,431
that could satisfy
such voracious appetites?
267
00:17:37,514 --> 00:17:41,351
To find out, the team need
to get down there themselves.
268
00:17:48,817 --> 00:17:51,028
{\an8}The
mission will be led by Zoleka,
269
00:17:51,111 --> 00:17:53,489
{\an8}the OceanXplorers'
deep sea researcher.
270
00:18:01,246 --> 00:18:02,664
For this mission,
271
00:18:02,748 --> 00:18:05,459
I'm partnering with Edie Widder,
272
00:18:05,542 --> 00:18:09,046
one of the world's most
experienced deep sea biologists.
273
00:18:10,172 --> 00:18:13,175
- You ready to dive?
- Yes!
274
00:18:15,969 --> 00:18:19,681
{\an8}SO Neptune, we
are ready to shut hatches.
275
00:18:21,683 --> 00:18:24,937
SO Bridge.
You are clear to roll sub out.
276
00:18:28,190 --> 00:18:29,858
Edie's
been pushing the envelope in
277
00:18:29,942 --> 00:18:33,112
ocean exploration
for over 40 years.
278
00:18:33,904 --> 00:18:36,448
That's
Neptune in the water.
279
00:18:36,532 --> 00:18:38,492
Venting now.
280
00:18:50,212 --> 00:18:53,757
Depth 2.0 meters.
Vents secure, descending over.
281
00:18:57,594 --> 00:19:00,013
Every
time we dive into the deep,
282
00:19:00,097 --> 00:19:02,432
we are heading into the unknown.
283
00:19:05,769 --> 00:19:09,398
We are explorers
and this is our spaceship.
284
00:19:13,402 --> 00:19:14,653
600 feet down
285
00:19:14,736 --> 00:19:17,322
the team enters
the twilight zone.
286
00:19:23,120 --> 00:19:25,747
A world dominated by darkness,
287
00:19:27,916 --> 00:19:30,210
and alien creatures.
288
00:19:36,175 --> 00:19:37,217
Oh look at that.
289
00:19:37,301 --> 00:19:39,094
Look at that.
290
00:19:39,553 --> 00:19:41,305
What are you seeing?
291
00:19:42,723 --> 00:19:44,975
{\an8}
It's a glass squid.
292
00:19:45,058 --> 00:19:46,727
{\an8}A rare sighting.
293
00:20:00,282 --> 00:20:04,328
Being transparent
that's a defense mechanism.
294
00:20:05,996 --> 00:20:09,041
It's such an amazing adaptation.
295
00:20:09,124 --> 00:20:10,834
You see it a lot in the ocean,
296
00:20:10,918 --> 00:20:13,128
but you don't
see it much on land.
297
00:20:21,053 --> 00:20:22,554
At 1500 feet,
298
00:20:22,638 --> 00:20:25,224
they find even
more signs of life.
299
00:20:26,099 --> 00:20:27,893
- What is that?
- Where? Where?
300
00:20:27,976 --> 00:20:30,062
Look, turn to
the right, turn to the right.
301
00:20:30,145 --> 00:20:32,481
It's ink. But it's so much.
302
00:20:32,564 --> 00:20:34,483
Oh my God!
303
00:20:36,693 --> 00:20:39,363
Oh yeah. That's
a massive plume of ink.
304
00:20:40,739 --> 00:20:42,866
Where is the squid though?
305
00:20:43,367 --> 00:20:45,494
- Oh squid.
- Squid!
306
00:20:46,078 --> 00:20:47,371
A bird squid.
307
00:20:47,829 --> 00:20:49,331
{\an8}- Hello.
Hello.
308
00:20:49,414 --> 00:20:50,791
{\an8}And
this one has attitude!
309
00:20:50,916 --> 00:20:53,377
{\an8}- Oh my gosh.
Beautiful. Oh look at it.
310
00:20:53,460 --> 00:20:55,545
{\an8}
311
00:20:58,465 --> 00:21:00,008
I think he's
trying to eat Zoleka.
312
00:21:00,092 --> 00:21:02,678
Yeah. I'm squid food.
313
00:21:13,188 --> 00:21:15,691
As the
sub dives to 2500 feet,
314
00:21:15,774 --> 00:21:18,986
Zoleka spots
something extraordinary.
315
00:21:19,444 --> 00:21:21,446
Oh my word.
316
00:21:22,239 --> 00:21:24,491
{\an8}Is that a whiplash squid?
317
00:21:28,287 --> 00:21:30,872
Look how exquisite it is.
318
00:21:33,208 --> 00:21:34,960
All squid
can change color by expanding
319
00:21:35,043 --> 00:21:39,381
or contracting cells in their
skin called chromatophores.
320
00:21:42,592 --> 00:21:44,094
Do
you think, do you think
321
00:21:44,177 --> 00:21:47,347
it's signaling to other squid?
322
00:21:48,098 --> 00:21:50,058
Yoo!
323
00:21:51,018 --> 00:21:53,812
Is this an alarm signal?
324
00:21:55,188 --> 00:21:59,151
How does one even decode
what we're really seeing here?
325
00:22:03,780 --> 00:22:07,909
I'd like to think I'm a
level-headed scientist but wow.
326
00:22:07,993 --> 00:22:12,789
When you come across
an encounter like this,
327
00:22:12,873 --> 00:22:16,418
it's absolutely
stunning, absolutely stunning.
328
00:22:18,045 --> 00:22:20,505
This is why we do it Edie.
329
00:22:21,965 --> 00:22:24,926
Sperm whales
do prey on whiplash squid but
330
00:22:25,010 --> 00:22:28,930
they're so small, they'd need
to eat thousands every day.
331
00:22:34,978 --> 00:22:39,566
At 3300 feet, they approach the
boundary of the midnight zone.
332
00:22:43,987 --> 00:22:45,822
The
midnight zone is pitch black
333
00:22:45,906 --> 00:22:48,075
and it's freezing.
334
00:22:48,158 --> 00:22:50,410
But as hostile as this place is,
335
00:22:50,494 --> 00:22:53,163
this is where the
sperm whale finds its food.
336
00:22:53,246 --> 00:22:56,041
So it's important that we
go take a look down there.
337
00:22:57,626 --> 00:23:00,545
But the sub
reaches its maximum dive depth.
338
00:23:00,629 --> 00:23:03,340
It can't go any further.
339
00:23:10,514 --> 00:23:12,766
Control,
control, Neptune
340
00:23:12,849 --> 00:23:15,894
passing five zero meters,
clear to surface.
341
00:23:26,947 --> 00:23:28,990
If they want
to search the midnight zone for
342
00:23:29,074 --> 00:23:32,285
larger sperm whale prey
the team will have to
343
00:23:32,369 --> 00:23:34,413
mobilize the ship's ROV.
344
00:23:35,163 --> 00:23:37,165
A remotely operated vehicle.
345
00:23:43,463 --> 00:23:45,424
The ROV is
capable of going to depths of
346
00:23:45,507 --> 00:23:47,134
20,000 feet.
347
00:23:47,217 --> 00:23:49,886
So getting to 5,000 feet where
the sperm whales are going,
348
00:23:49,970 --> 00:23:52,055
should be no problem at all.
349
00:23:57,727 --> 00:23:59,354
Melissa baits the ROV with
350
00:23:59,438 --> 00:24:02,274
deep-water squid's
favorite meal,
351
00:24:02,357 --> 00:24:04,109
other squid.
352
00:24:04,192 --> 00:24:07,279
And that
is a squid ready to be lifelike
353
00:24:07,362 --> 00:24:09,531
in the water column.
354
00:24:26,673 --> 00:24:28,425
Through
its tether to the ship,
355
00:24:28,508 --> 00:24:31,136
the ROV sends
back a live picture.
356
00:24:36,516 --> 00:24:38,351
Exploring
the deep you often see something
357
00:24:38,435 --> 00:24:41,146
that you have never seen before,
but you hope that you're gonna
358
00:24:41,229 --> 00:24:43,648
see something
no-one has seen before.
359
00:24:49,696 --> 00:24:51,239
Lights off.
360
00:24:58,705 --> 00:25:01,583
Oh,
incoming, incoming, here we go.
361
00:25:02,918 --> 00:25:04,044
- Keep, whoa.
- Whoa!
362
00:25:04,127 --> 00:25:05,587
What is that?
363
00:25:09,841 --> 00:25:12,260
Bingo. Kitefin shark.
364
00:25:14,596 --> 00:25:16,431
{\an8}The squid
lure has drawn in more than
365
00:25:16,515 --> 00:25:18,391
{\an8}the team bargained for.
366
00:25:19,184 --> 00:25:20,977
He
looks like a good size.
367
00:25:22,020 --> 00:25:25,023
These guys can get up to
like 30 pounds on average.
368
00:25:26,274 --> 00:25:29,069
Sperm whales, yeah they do
eat them but actually have
369
00:25:29,152 --> 00:25:30,612
a preference for squid.
370
00:25:35,033 --> 00:25:37,661
After hours in
the deep and just one encounter
371
00:25:37,744 --> 00:25:41,915
with the kitefin, the
team wonders if the noise from
372
00:25:41,998 --> 00:25:44,543
the ROV could be
scaring off the squid.
373
00:25:49,673 --> 00:25:52,467
Time to try a
different approach.
374
00:25:56,680 --> 00:26:00,308
{\an8}Marine biologist
Nathan Robinson has the perfect
375
00:26:00,392 --> 00:26:02,435
{\an8}camera rig for this mission.
376
00:26:05,855 --> 00:26:08,108
The
angler is a stealth camera,
377
00:26:08,191 --> 00:26:10,235
makes no noise.
378
00:26:10,318 --> 00:26:13,530
It's also very
light sensitive so this
379
00:26:13,613 --> 00:26:17,576
actually really is perfect for
seeing animals in the deep sea.
380
00:26:36,511 --> 00:26:38,847
Going down.
381
00:26:40,223 --> 00:26:42,809
Okay, keep letting it go.
382
00:26:45,061 --> 00:26:47,897
Lowering the
angler on a fishing line may
383
00:26:47,981 --> 00:26:51,526
look low tech, but
this is our secret weapon.
384
00:26:52,986 --> 00:26:59,326
It can dive to 6,500 feet and
then just sit there completely
385
00:26:59,409 --> 00:27:04,331
silent and still, so as not
to scare away any wildlife.
386
00:27:09,127 --> 00:27:12,005
The angler
is armed with an E-Jelly.
387
00:27:12,088 --> 00:27:15,425
An LED array that mimics
the defense mechanism of
388
00:27:15,508 --> 00:27:19,804
{\an8}the Atolla jellyfish, which
lights up when threatened to try
389
00:27:19,888 --> 00:27:22,182
{\an8}and attract an
even larger predator in
390
00:27:22,265 --> 00:27:24,392
{\an8}the hope that it will
scare off the attacker.
391
00:27:28,563 --> 00:27:32,651
After hours in the deep, the
rig is ready to be retrieved.
392
00:27:39,240 --> 00:27:41,201
Only once back aboard,
will the team discover if
393
00:27:41,284 --> 00:27:44,287
their covert mission
has been a success.
394
00:27:50,919 --> 00:27:52,962
Right, you
ready to bring it to the lab?
395
00:27:53,046 --> 00:27:55,382
Yeah.
396
00:28:02,555 --> 00:28:05,183
Okay. So now we're
going down to the bottom.
397
00:28:12,732 --> 00:28:14,275
Oh my God, what a catch.
398
00:28:17,028 --> 00:28:18,655
{\an8}These
flying squid are known
399
00:28:18,738 --> 00:28:20,490
{\an8}sperm whale prey.
400
00:28:23,243 --> 00:28:26,913
We've
been seeing a ton of squid,
401
00:28:26,996 --> 00:28:29,416
conducting these hit
and run attacks on the bait
402
00:28:29,499 --> 00:28:31,209
and the E-Jelly.
403
00:28:35,672 --> 00:28:40,719
They are large, very
nutritious food items for
404
00:28:40,802 --> 00:28:42,679
something like a sperm whale.
405
00:28:46,850 --> 00:28:48,268
Hours into the footage,
406
00:28:48,560 --> 00:28:50,812
Nathan and Eric spot
something even larger,
407
00:28:51,479 --> 00:28:53,982
and they gather
the rest of the team.
408
00:28:55,817 --> 00:28:57,277
Just watch this.
409
00:29:00,572 --> 00:29:01,656
What the heck!
410
00:29:01,740 --> 00:29:03,616
That
is a really big squid.
411
00:29:03,700 --> 00:29:05,702
So this
species is the third largest
412
00:29:05,785 --> 00:29:06,786
in the oceans.
413
00:29:07,412 --> 00:29:10,123
Dana octopus
squid is the, the common name.
414
00:29:10,290 --> 00:29:12,834
{\an8}It's got light organs
on the ends of its arms,
415
00:29:12,917 --> 00:29:14,544
{\an8}that are like
the size of lemons.
416
00:29:14,836 --> 00:29:16,921
Look at them!
They're glowing so bright.
417
00:29:17,005 --> 00:29:19,257
Why would you
have such bright lights there?
418
00:29:19,340 --> 00:29:21,009
- To blind you.
- Oh!
419
00:29:21,092 --> 00:29:22,093
It's like
a deer in the headlights...
420
00:29:22,177 --> 00:29:23,178
Yeah.
421
00:29:23,261 --> 00:29:24,262
So
you've got your little critter,
422
00:29:24,345 --> 00:29:25,680
your crustacean
that you want to eat,
423
00:29:25,764 --> 00:29:29,476
you shine these big kinda
lemon size lights right at it,
424
00:29:29,559 --> 00:29:32,020
it can't see what's
coming from what direction
425
00:29:32,103 --> 00:29:33,938
and then bam you take it down.
426
00:29:35,857 --> 00:29:38,401
Weighing as
much as a full-grown gorilla,
427
00:29:39,152 --> 00:29:43,448
a sperm whale only needs to
hunt five of these giants a day.
428
00:29:43,615 --> 00:29:48,203
This is
actually the most common, uh,
429
00:29:48,286 --> 00:29:51,080
species that sperm whales
eat in terms of weight.
430
00:29:51,164 --> 00:29:53,041
This is
actually, this is staple food.
431
00:29:53,124 --> 00:29:54,209
- This is, exactly.
- This is number one.
432
00:29:54,292 --> 00:29:55,293
This is
what they're eating, yeah.
433
00:29:55,376 --> 00:29:57,170
But
they've hardly ever been seen.
434
00:29:57,253 --> 00:29:58,505
I'm
actually pretty sure this is
435
00:29:58,588 --> 00:30:01,049
the first footage we
have of dana octopus squid,
436
00:30:01,132 --> 00:30:02,300
in the Atlantic.
437
00:30:02,383 --> 00:30:03,510
This is amazing.
438
00:30:06,429 --> 00:30:07,931
Thanks
to the deep-water team,
439
00:30:08,014 --> 00:30:11,726
we've seen squid down
there large enough to feed this
440
00:30:11,810 --> 00:30:14,354
huge population of sperm whales.
441
00:30:22,195 --> 00:30:24,864
But what's fueling
this rich ecosystem?
442
00:30:25,490 --> 00:30:29,202
It's all down to the
tiniest organisms in the ocean.
443
00:30:31,454 --> 00:30:34,582
{\an8}When deep ocean currents hit
the island's underwater slopes,
444
00:30:34,666 --> 00:30:37,752
{\an8}nutrient rich water is
forced up toward the surface.
445
00:30:39,003 --> 00:30:41,422
These nutrients feed
microorganisms that form
446
00:30:41,506 --> 00:30:43,299
the base of the food web,
447
00:30:44,968 --> 00:30:46,511
and the more there are,
448
00:30:46,594 --> 00:30:49,639
the more life this
ecosystem can support.
449
00:30:58,106 --> 00:31:02,235
To find out just how rich
these waters are Edie and Zoleka
450
00:31:02,318 --> 00:31:05,029
once again take a
dive into the deep.
451
00:31:20,920 --> 00:31:23,548
The density of this
microscopic life is difficult
452
00:31:23,631 --> 00:31:25,925
to judge in these dark waters
453
00:31:27,802 --> 00:31:31,222
but Edie has a
magic trick to reveal it.
454
00:31:44,110 --> 00:31:45,904
600 meters.
455
00:31:49,282 --> 00:31:51,576
Oh
I hope this works.
456
00:31:52,577 --> 00:31:53,620
Okay, you ready?
457
00:31:53,703 --> 00:31:55,038
We're ready.
458
00:31:55,121 --> 00:31:57,957
Three, two, one.
Lights coming on.
459
00:32:05,465 --> 00:32:06,799
Nothing.
460
00:32:10,136 --> 00:32:12,430
Let's drop down.
461
00:32:12,513 --> 00:32:15,433
Control, Neptune.
We are descending.
462
00:32:23,399 --> 00:32:25,902
Okay
let's try it again.
463
00:32:30,865 --> 00:32:34,577
Okay three,
two, one, lights coming on.
464
00:32:39,791 --> 00:32:41,084
It worked!
465
00:32:43,086 --> 00:32:44,420
Wow!
466
00:32:50,510 --> 00:32:53,262
Bioluminescence in action.
467
00:32:59,185 --> 00:33:02,522
It's like I'm wrapped
in a blanket of stars.
468
00:33:06,985 --> 00:33:09,612
This is the base
of the food chain.
469
00:33:10,863 --> 00:33:15,910
The fish eat the plankton
and the squid eat the fish and
470
00:33:15,994 --> 00:33:18,746
then the sperm whales
are feeding on the squid.
471
00:33:19,414 --> 00:33:21,374
This is where it all begins.
472
00:33:21,457 --> 00:33:24,585
Smallest to the biggest.
473
00:33:29,632 --> 00:33:32,260
That's fantastic.
474
00:33:33,094 --> 00:33:35,430
Edie's witnessed
this bioluminescent phenomenon
475
00:33:35,513 --> 00:33:39,058
her entire career, but has
never had the technology to
476
00:33:39,142 --> 00:33:41,519
share it with the world...
477
00:33:43,855 --> 00:33:45,106
Until now.
478
00:33:49,068 --> 00:33:51,821
Wow.
Thanks Edie, we got it.
479
00:33:52,613 --> 00:33:54,615
It's
like having seen UFOs and
480
00:33:54,699 --> 00:33:56,701
now suddenly there's evidence.
481
00:33:56,784 --> 00:33:59,162
Okay. Can we do that again?
482
00:33:59,245 --> 00:34:00,872
Absolutely.
483
00:34:03,958 --> 00:34:06,627
Without this
abundance of tiny life,
484
00:34:06,711 --> 00:34:10,131
the squid and the sperm whales
couldn't survive here.
485
00:34:10,214 --> 00:34:12,842
It's very,
very humbling to think that
486
00:34:13,301 --> 00:34:17,263
no matter how tiny you are
you can do gigantic things.
487
00:34:28,232 --> 00:34:30,109
Control, control.
Neptune's ascending over.
488
00:34:30,193 --> 00:34:31,319
Clear to surface.
489
00:34:31,402 --> 00:34:32,695
Clear to surface.
490
00:34:32,779 --> 00:34:34,238
Welcome back Neptune.
491
00:34:34,322 --> 00:34:36,240
Blow your tanks.
492
00:34:39,160 --> 00:34:40,495
Well did
you enjoy that dive?
493
00:34:40,578 --> 00:34:41,913
Oh. Are you kidding!
494
00:34:41,996 --> 00:34:43,790
That was actually
on my bucket list.
495
00:34:51,672 --> 00:34:54,008
You know, as I get older,
every expedition I go on,
496
00:34:54,092 --> 00:34:57,220
I figure this might be the last
497
00:34:57,303 --> 00:34:59,806
and if this is the
last it's the best.
498
00:34:59,889 --> 00:35:02,391
It's just been
absolutely amazing.
499
00:35:11,442 --> 00:35:13,319
In their
time here in the Azores,
500
00:35:13,402 --> 00:35:16,280
the team has captured
the first ever images of
501
00:35:16,364 --> 00:35:19,367
a sperm whale diving
into these deep waters.
502
00:35:26,332 --> 00:35:28,334
This is the
culmination of a huge amount of
503
00:35:28,417 --> 00:35:30,294
effort and many
sleepless nights,
504
00:35:30,461 --> 00:35:33,714
but at the end of the day
we got those few minutes of
505
00:35:33,798 --> 00:35:35,424
incredibly priceless footage
506
00:35:35,842 --> 00:35:38,177
that made the
whole thing worth it.
507
00:35:38,261 --> 00:35:40,054
It was awesome!
508
00:35:43,474 --> 00:35:45,643
They've
added to the image catalogue of
509
00:35:45,726 --> 00:35:48,563
the squid that
feed the sperm whales.
510
00:35:50,398 --> 00:35:52,024
Thanks to the OceanXplorer,
511
00:35:52,108 --> 00:35:54,318
we've been able to dive deep
into the world of sperm whales
512
00:35:54,402 --> 00:35:58,030
here and discovered this
interaction between them and
513
00:35:58,114 --> 00:36:00,658
massive squid that's
never really been observed
514
00:36:00,741 --> 00:36:03,369
here before, which
is pretty mind blowing.
515
00:36:07,081 --> 00:36:08,583
And
they've documented the normally
516
00:36:08,666 --> 00:36:12,753
invisible riches that
fuel this entire ecosystem.
517
00:36:15,173 --> 00:36:17,466
It's fabulous!
518
00:36:17,633 --> 00:36:19,635
I am one
of the few people to witness
519
00:36:19,719 --> 00:36:23,890
a bioluminescence light show
and I'm so excited to share
520
00:36:24,056 --> 00:36:25,391
this with the world.
521
00:36:28,477 --> 00:36:30,688
That is mind blowing.
522
00:36:40,573 --> 00:36:43,492
We've still got so
much to learn about these whales
523
00:36:43,576 --> 00:36:47,455
but seeing them live in
harmony they could definitely
524
00:36:47,538 --> 00:36:49,040
teach us a thing or two.
525
00:36:49,123 --> 00:36:50,625
No, ho, oh!
