For a moment, what I need to do
0
1000
2000
00:18
is project something on the screen of your imagination.
1
3000
3000
00:23
We're in 17th century Japan
2
8000
2000
00:25
on the west coast,
3
10000
3000
00:28
and a little, wizened monk
4
13000
3000
00:31
is hurrying along, near midnight,
5
16000
3000
00:34
to the crest of a small hill.
6
19000
3000
00:37
He arrives on the small hill,
7
22000
2000
00:39
dripping with water.
8
24000
2000
00:41
He stands there,
9
26000
2000
00:43
and he looks across at the island, Sado.
10
28000
3000
00:46
And he scans across the ocean, and he looks at the sky.
11
31000
3000
00:51
Then he says to himself, very quietly,
12
36000
3000
00:55
"[Turbulent the sea,]
13
40000
3000
00:58
[Stretching across to Sado]
14
43000
3000
01:01
[The Milky Way]."
15
46000
3000
01:04
Basho was a brilliant man.
16
49000
2000
01:08
He said more with less
17
53000
2000
01:10
than any human
18
55000
2000
01:12
that I have ever read or talked to.
19
57000
3000
01:16
Basho, in 17 syllables,
20
61000
3000
01:19
juxtaposed
21
64000
3000
01:22
a turbulent ocean
22
67000
2000
01:24
driven by a storm now past,
23
69000
3000
01:28
and captured the almost
24
73000
3000
01:31
impossible beauty
25
76000
3000
01:34
of our home galaxy
26
79000
3000
01:37
with millions of stars,
27
82000
4000
01:41
probably hundreds and hundreds of -- who knows how many -- planets,
28
86000
3000
01:44
maybe even an ocean
29
89000
2000
01:46
that we will probably call Sylvia in time.
30
91000
3000
01:52
As he was nearing his death,
31
97000
3000
01:55
his disciples and followers
32
100000
3000
01:58
kept asking him,
33
103000
2000
02:00
"What's the secret?
34
105000
2000
02:02
How can you
35
107000
2000
02:04
make haiku poems so beautiful so easily?"
36
109000
3000
02:09
And toward the end, he said,
37
114000
3000
02:14
"If you would know the pine tree,
38
119000
3000
02:17
go to the pine tree."
39
122000
3000
02:20
That was it.
40
125000
2000
02:22
(Laughter)
41
127000
3000
02:25
Sylvia has said we must use
42
130000
2000
02:27
every capacity we have
43
132000
3000
02:30
in order to know the oceans.
44
135000
2000
02:32
If we would know the oceans,
45
137000
2000
02:34
we must go to the oceans.
46
139000
2000
02:36
And what I'd like to talk to you today about, a little bit,
47
141000
3000
02:39
is really transforming
48
144000
3000
02:42
the relationship, or the interplay,
49
147000
3000
02:45
between humans and oceans
50
150000
2000
02:47
with a new capability
51
152000
3000
02:50
that is not at all routine yet.
52
155000
2000
02:52
I hope it will be.
53
157000
2000
02:55
There are a few key points.
54
160000
2000
02:57
One of them is the oceans are central
55
162000
2000
02:59
to the quality of life on earth.
56
164000
3000
03:03
Another is that there are bold, new ways
57
168000
3000
03:06
of studying oceans
58
171000
2000
03:08
that we have not used well yet.
59
173000
3000
03:11
And the last is that these bold, new ways
60
176000
2000
03:13
that we are exploring
61
178000
2000
03:15
as a community
62
180000
2000
03:17
will transform the way we look at our planet, our oceans,
63
182000
3000
03:20
and eventually how we manage
64
185000
2000
03:22
probably the entire planet, for what it's worth.
65
187000
3000
03:27
So what scientists do when they begin
66
192000
2000
03:29
is to start with the system.
67
194000
2000
03:31
They define what the system is.
68
196000
2000
03:33
The system isn't Chesapeake Bay.
69
198000
2000
03:35
It's not the Kuril arc. It's not even the entire Pacific.
70
200000
3000
03:38
It's the whole planet,
71
203000
2000
03:40
the entire planet, continents and oceans together.
72
205000
3000
03:43
That's the system.
73
208000
2000
03:45
And basically, our challenge
74
210000
2000
03:47
is to optimize the benefits
75
212000
3000
03:50
and mitigate the risks
76
215000
2000
03:52
of living on a planet that's driven by only two processes,
77
217000
3000
03:55
two sources of energy,
78
220000
2000
03:57
one of which is solar,
79
222000
2000
03:59
that drives the winds, the waves,
80
224000
2000
04:01
the clouds, the storms and photosynthesis.
81
226000
3000
04:04
The second one is internal energy.
82
229000
2000
04:06
And these two war against one another
83
231000
2000
04:08
almost continuously.
84
233000
2000
04:10
Mountain ranges, plate tectonics,
85
235000
2000
04:12
moves the continents around, forms ore deposits.
86
237000
3000
04:15
Volcanoes erupt.
87
240000
2000
04:17
That's the planet that we live on.
88
242000
2000
04:19
It's immensely complex.
89
244000
2000
04:21
Now I don't expect all of you to see all the details here,
90
246000
2000
04:23
but what I want you to see is
91
248000
2000
04:25
this is about 10 percent
92
250000
3000
04:28
of the processes that operate within
93
253000
2000
04:30
the oceans almost continuously,
94
255000
2000
04:32
and have for the last 4 billion years.
95
257000
3000
04:35
This is a system that's been around a very long time.
96
260000
3000
04:38
And these have all co-evolved.
97
263000
2000
04:40
What do I mean by that?
98
265000
2000
04:42
They interact with one another constantly.
99
267000
3000
04:45
All of them interact with one another.
100
270000
3000
04:48
So the complexity of this system that we're looking at,
101
273000
3000
04:51
the one driven by the sun --
102
276000
2000
04:53
upper portion, mostly --
103
278000
2000
04:55
and the lower portion is partly driven
104
280000
2000
04:57
by the input from heat below
105
282000
2000
04:59
and by other processes.
106
284000
2000
05:01
This is very, very important
107
286000
2000
05:03
because this is the system, this is the crucible,
108
288000
2000
05:05
out of which life on the planet came,
109
290000
3000
05:08
and it's now time for us to understand it.
110
293000
3000
05:11
We must understand it.
111
296000
3000
05:14
That's one of the themes that Sylvia reminds us about:
112
299000
2000
05:16
understand this ocean of ours,
113
301000
3000
05:19
this basic life support system,
114
304000
3000
05:22
the dominant life support system on the planet.
115
307000
3000
05:26
Look at this complexity here.
116
311000
2000
05:28
This is only one variable.
117
313000
2000
05:30
If you can see the complexity,
118
315000
2000
05:32
you can see how
119
317000
2000
05:34
tiny, little eddies
120
319000
3000
05:37
and large eddies and the motion --
121
322000
2000
05:39
this is just sea surface temperature,
122
324000
2000
05:41
but it's immensely complicated.
123
326000
2000
05:43
Now a layer in,
124
328000
2000
05:45
the other two or three hundred processes
125
330000
2000
05:47
that are all interacting,
126
332000
2000
05:49
partly as a function of temperature, partly as a function of all the other factors,
127
334000
3000
05:52
and you've got a really complicated system.
128
337000
2000
05:54
That's our challenge, is to understand,
129
339000
3000
05:57
understand this system in new and phenomenal ways.
130
342000
3000
06:00
And there's an urgency to this.
131
345000
3000
06:03
Part of the urgency comes from the fact
132
348000
2000
06:05
that, of order, a billion people on the planet currently
133
350000
3000
06:08
are undernourished or starving.
134
353000
3000
06:11
And part of the issue
135
356000
2000
06:13
is for Cody --
136
358000
3000
06:16
who's here,
137
361000
2000
06:18
16 years old --
138
363000
2000
06:20
and I have permission to relay this number.
139
365000
3000
06:23
When he, 40 years from now,
140
368000
3000
06:26
is the age of Nancy Brown,
141
371000
2000
06:28
there are going to be
142
373000
3000
06:31
another two and a half billion people on the planet.
143
376000
3000
06:35
We can't solve all the problems
144
380000
3000
06:38
by looking only at the oceans,
145
383000
2000
06:40
but if we don't understand
146
385000
2000
06:42
the fundamental life support system of this planet
147
387000
2000
06:44
much more thoroughly than we do now,
148
389000
2000
06:46
then the stresses that we will face,
149
391000
2000
06:48
and that Cody will face,
150
393000
2000
06:50
and even Nancy, who's going to live till she's 98,
151
395000
3000
06:53
will have really problems coping.
152
398000
3000
06:58
All right, let's talk about another perspective
153
403000
2000
07:00
on the importance of the oceans.
154
405000
3000
07:03
Look at this diagram, which is showing
155
408000
3000
07:06
warm waters in red,
156
411000
2000
07:08
cool waters in blue,
157
413000
2000
07:10
and on the continents, what you're seeing in bright green,
158
415000
3000
07:13
is the growth of vegetation,
159
418000
2000
07:15
and in olive green, the dieback of vegetation.
160
420000
2000
07:17
And in the lower left hand corner there's a clock ticking away
161
422000
3000
07:20
from 1982 to 1998
162
425000
2000
07:22
and then cycling again.
163
427000
2000
07:25
What you'll see is that the rhythms
164
430000
2000
07:27
of growth, of vegetation --
165
432000
3000
07:30
a subset of which is food on the continents --
166
435000
2000
07:32
is directly tied to the rhythms
167
437000
2000
07:34
of the sea surface temperatures.
168
439000
3000
07:37
The oceans control,
169
442000
2000
07:39
or at least significantly influence,
170
444000
3000
07:42
correlate with,
171
447000
2000
07:44
the growth patterns and the drought patterns
172
449000
2000
07:46
and the rain patterns on the continents.
173
451000
2000
07:48
So people in Kansas, in a wheat field in Kansas,
174
453000
3000
07:51
need to understand that the oceans
175
456000
2000
07:53
are central to them as well.
176
458000
2000
07:55
Another complexity: this is the age of the oceans.
177
460000
3000
07:58
I'm going to layer in on top of this
178
463000
2000
08:00
the tectonic plates.
179
465000
3000
08:03
The age of the ocean, the tectonic plates,
180
468000
3000
08:06
gives rise to a totally new phenomenon
181
471000
2000
08:08
that we have heard about
182
473000
2000
08:10
in this conference.
183
475000
2000
08:12
And I share with you some very high-definition video
184
477000
3000
08:15
that we collected in real time.
185
480000
3000
08:18
Seconds after this video was taken,
186
483000
3000
08:21
people in Beijing,
187
486000
2000
08:23
people in Sydney, people in Amsterdam,
188
488000
2000
08:25
people in Washington D.C. were watching this.
189
490000
3000
08:28
Now you've heard of hydrothermal vents,
190
493000
2000
08:30
but the other discovery
191
495000
2000
08:32
is that deep below the sea floor,
192
497000
3000
08:35
there is vast reservoir of microbial activity,
193
500000
3000
08:38
which we have only just discovered
194
503000
2000
08:40
and we have almost no way to study.
195
505000
3000
08:43
Some people have estimated
196
508000
2000
08:45
that the biomass
197
510000
2000
08:47
tied up in these microbes
198
512000
2000
08:49
living in the pours and the cracks
199
514000
2000
08:51
of the sea floor and below
200
516000
3000
08:54
rival the total amount of living biomass
201
519000
2000
08:56
at the surface of the planet.
202
521000
2000
08:58
It's an astonishing insight,
203
523000
2000
09:00
and we have only found out about this recently.
204
525000
2000
09:02
This is very, very exciting.
205
527000
3000
09:05
It may be the next rainforest,
206
530000
3000
09:08
in terms of pharmaceuticals.
207
533000
2000
09:10
We know little or nothing about it.
208
535000
3000
09:14
Well, Marcel Proust has this wonderful saying
209
539000
3000
09:17
that, "The real voyage of discovery
210
542000
2000
09:19
consists not so much in seeking new territory,
211
544000
3000
09:22
but possibly in having new sets of eyes,"
212
547000
3000
09:25
new ways of seeing things,
213
550000
2000
09:27
a new mindset.
214
552000
2000
09:29
And many of you remember
215
554000
2000
09:31
the early stages of oceanography,
216
556000
2000
09:33
when we had to use what we had at our fingertips.
217
558000
3000
09:36
And it wasn't easy. It wasn't easy in those days.
218
561000
3000
09:39
Some of you remember this, I'm sure.
219
564000
3000
09:44
And now, we have an entire suite of tools
220
569000
3000
09:47
that are really pretty powerful --
221
572000
2000
09:49
ships, satellites, moorings.
222
574000
3000
09:53
But they don't quite cut it. They don't quite give us what we need.
223
578000
3000
09:56
And the program that I wanted to talk to you about
224
581000
2000
09:58
just a little bit here,
225
583000
2000
10:00
was funded, and it involves autonomous vehicles
226
585000
3000
10:03
like the one running across the base of this image.
227
588000
3000
10:06
Modeling: on the right hand side,
228
591000
3000
10:09
there's a very complex computational model.
229
594000
3000
10:12
On the left hand side, there's a new type of mooring,
230
597000
2000
10:14
which I'll show you in just a second.
231
599000
2000
10:16
And on the basis
232
601000
2000
10:18
of several points,
233
603000
2000
10:20
the oceans are complex, and they're central to the life on earth.
234
605000
3000
10:23
They are changing rapidly, but not predictably.
235
608000
3000
10:26
And the models that we need to predict the future
236
611000
2000
10:28
do not have enough data to refine them.
237
613000
2000
10:30
The computational power
238
615000
2000
10:32
is amazing.
239
617000
2000
10:34
But without data, those models
240
619000
2000
10:36
will never ever be predicted.
241
621000
2000
10:38
And that's what we really need.
242
623000
2000
10:40
For a variety of reasons they're dangerous,
243
625000
2000
10:42
but we feel that OOI,
244
627000
2000
10:44
this Ocean Observatory Initiative,
245
629000
2000
10:46
which the National Science Foundation
246
631000
2000
10:48
has begun to fund,
247
633000
2000
10:50
has the potential to really transform things.
248
635000
2000
10:52
And the goal of the program is to
249
637000
2000
10:54
launch an era of scientific discovery
250
639000
2000
10:56
and understanding
251
641000
2000
10:58
across and within the ocean basins,
252
643000
2000
11:00
utilizing widely accessible,
253
645000
3000
11:03
interactive telepresence.
254
648000
3000
11:06
It's a new world.
255
651000
2000
11:08
We will be present throughout
256
653000
2000
11:10
the volume of the ocean, at will,
257
655000
3000
11:13
communicating in real time.
258
658000
2000
11:15
And this is what the system involves,
259
660000
2000
11:17
a number of sites in the southern hemisphere,
260
662000
3000
11:20
shown in those circles.
261
665000
2000
11:22
And in the northern hemisphere there are four sites.
262
667000
2000
11:24
I won't talk a lot about most of them right here,
263
669000
3000
11:27
but the one on the west coast, that's in the box,
264
672000
2000
11:29
is called the regional scale nodes.
265
674000
3000
11:32
It was once called Neptune.
266
677000
2000
11:34
And let me show you what's behind it.
267
679000
3000
11:37
Fiber: next-generation way of communicating.
268
682000
3000
11:40
You can see the copper tips on these things.
269
685000
3000
11:43
You can transmit power,
270
688000
2000
11:45
but the bandwidth is in those tiny, little threads
271
690000
3000
11:48
smaller than the hair on your head in diameter.
272
693000
3000
11:51
And this particular set here
273
696000
3000
11:54
can transmit something of the order of
274
699000
2000
11:56
three to five terabits per second.
275
701000
3000
11:59
This is phenomenal bandwidth.
276
704000
2000
12:01
And this is what the planet looks like.
277
706000
2000
12:03
We are already laced up
278
708000
2000
12:05
as if we're in a fiber optic corset, if you like.
279
710000
3000
12:08
This is what it looks like.
280
713000
2000
12:10
And the cables go really continent to continent.
281
715000
3000
12:13
It's a very powerful system,
282
718000
2000
12:15
and most of our communications consist of it.
283
720000
2000
12:17
So this is the system that I'm talking about,
284
722000
2000
12:19
off the west coast. It's coincident with the tectonic plate,
285
724000
3000
12:22
the Juan de Fuca tectonic plate.
286
727000
2000
12:24
And it's going to deliver abundant power
287
729000
2000
12:26
and unprecedented bandwidth
288
731000
2000
12:28
across this entire volume --
289
733000
2000
12:30
in the overlying ocean,
290
735000
2000
12:32
on the sea floor and below the sea floor.
291
737000
2000
12:34
Bandwidth and power
292
739000
2000
12:36
and a wide variety of processes
293
741000
2000
12:38
that will be operating.
294
743000
2000
12:40
This is what one of those primary nodes looks like,
295
745000
2000
12:42
and it's like a sub station with power and bandwidth
296
747000
3000
12:45
that can spread out over an area the size of Seattle.
297
750000
3000
12:49
And the kind of science that can be done
298
754000
2000
12:51
will be determined by a variety of scientists who want to be involved
299
756000
3000
12:54
and can bring the instrumentation to the table.
300
759000
3000
12:57
They will bring it and link it in.
301
762000
2000
12:59
It'll be, in a sense, like having time on a telescope,
302
764000
3000
13:02
except you'll have your own port.
303
767000
3000
13:05
Climate change, ocean acidification,
304
770000
2000
13:07
dissolved oxygen,
305
772000
2000
13:09
carbon cycle, coastal upwelling,
306
774000
2000
13:11
fishing dynamics --
307
776000
2000
13:13
the full spectrum of
308
778000
2000
13:15
earth science and ocean science
309
780000
2000
13:17
simultaneously in the same volume.
310
782000
2000
13:19
So anyone coming along later
311
784000
2000
13:21
simply accesses the database
312
786000
3000
13:24
and can draw down the information they need
313
789000
2000
13:26
about anything that has taken place.
314
791000
2000
13:28
And this is just the first of these.
315
793000
3000
13:31
In conjunction with our Canadian colleagues, we've set this up.
316
796000
3000
13:34
Now I want to take you into the caldera.
317
799000
2000
13:36
On the left hand side there
318
801000
2000
13:38
is a large volcano called Axial Seamount.
319
803000
3000
13:41
And we're going to go down into the Axial Seamount
320
806000
2000
13:43
using animation.
321
808000
2000
13:45
Here's what this system is going to look like
322
810000
2000
13:47
that we are funded to build at this point.
323
812000
3000
13:50
Very powerful.
324
815000
2000
13:52
That's an elevator that's constantly moving up and down,
325
817000
2000
13:54
but it can be controlled by the folks on land
326
819000
3000
13:57
who are responsible for it.
327
822000
2000
13:59
Or they can transfer control
328
824000
2000
14:01
to someone in India or China
329
826000
2000
14:03
who can take over for a while,
330
828000
2000
14:05
because it's all going to be directly connected
331
830000
2000
14:07
through the Internet.
332
832000
2000
14:09
There will be massive amounts of data flowing ashore,
333
834000
3000
14:12
all available to anyone who has any interest in using it.
334
837000
3000
14:15
This is going to be much more powerful
335
840000
2000
14:17
than having a single ship
336
842000
2000
14:19
in a single location,
337
844000
2000
14:21
then move to a new location.
338
846000
2000
14:23
We're flying across the caldera floor.
339
848000
3000
14:27
There is a number of robotic systems.
340
852000
2000
14:29
There's cameras that can be turned on and off at your will,
341
854000
3000
14:32
if those are your experiments.
342
857000
2000
14:34
The kinds of systems that will be down there,
343
859000
2000
14:36
the kinds of instruments that will be on the sea floor,
344
861000
3000
14:39
consist of -- if you can read them there --
345
864000
2000
14:41
there's cameras, there's pressure sensors,
346
866000
2000
14:43
fluorometers, there's seismometers.
347
868000
2000
14:45
It's a full spectrum of tools.
348
870000
2000
14:47
Now, that mound right there
349
872000
2000
14:49
actually looks like this.
350
874000
2000
14:51
This is what it actually looks like.
351
876000
3000
14:54
And this is the kind of activity
352
879000
2000
14:56
that we can see with high-definition video,
353
881000
2000
14:58
because the bandwidth of these cables
354
883000
3000
15:01
is so huge
355
886000
2000
15:03
that we could have five to 10
356
888000
2000
15:05
stereo HD systems
357
890000
2000
15:07
running continuously
358
892000
2000
15:09
and, again, directed through robotic techniques from land.
359
894000
3000
15:14
Very, very powerful.
360
899000
3000
15:17
And these are the things that we're funded to do today.
361
902000
2000
15:19
So what can we actually do tomorrow?
362
904000
2000
15:21
We're about to ride the wave
363
906000
2000
15:23
of technological opportunity.
364
908000
3000
15:26
There are emerging technologies throughout
365
911000
3000
15:29
the field around oceanography,
366
914000
2000
15:31
which we will incorporate into oceanography,
367
916000
2000
15:33
and through that convergence,
368
918000
2000
15:35
we will transform oceanography into something even more magical.
369
920000
3000
15:39
Robotics systems are just incredible these days,
370
924000
3000
15:42
absolutely incredible.
371
927000
2000
15:44
And we will be bringing robotics of all sorts
372
929000
2000
15:46
into the ocean.
373
931000
2000
15:49
Nanotechnology: this is a small generator.
374
934000
2000
15:51
It's smaller than a postage stamp,
375
936000
2000
15:53
and it can generate power just by being
376
938000
2000
15:55
attached to your shirt as you move.
377
940000
2000
15:57
Just as you move, it generates power.
378
942000
3000
16:00
There are many kinds of things that can be used in the ocean, continuously.
379
945000
3000
16:05
Imaging: Many of you know a good deal more about this type of thing than I,
380
950000
3000
16:08
but stereo imaging at four times the definition
381
953000
3000
16:11
that we have in HD
382
956000
2000
16:13
will be routine within five years.
383
958000
2000
16:15
And this is the magic one.
384
960000
2000
16:17
As a result of the human genome process,
385
962000
2000
16:19
we are in a situation where
386
964000
2000
16:21
events that take place in the ocean --
387
966000
3000
16:24
like an erupting volcano, or something of that sort --
388
969000
2000
16:26
can actually be sampled.
389
971000
2000
16:28
We pump the fluid through one of these systems,
390
973000
3000
16:31
and we press the button,
391
976000
2000
16:33
and it's analyzed for the genomic character.
392
978000
2000
16:35
And that's transmitted back to land immediately.
393
980000
3000
16:38
So in the volume of the ocean,
394
983000
2000
16:40
we will know, not just the physics and the chemistry,
395
985000
3000
16:43
but the base of the food chain
396
988000
2000
16:45
will be transparent to us
397
990000
2000
16:47
with data on a continuous basis.
398
992000
3000
16:50
Grid computing: the power of grid computers
399
995000
2000
16:52
is going to be just amazing here.
400
997000
2000
16:54
We will soon be using grid computing
401
999000
2000
16:56
to do pretty much everything, like adjust the data
402
1001000
3000
16:59
and everything
403
1004000
2000
17:01
that goes with the data.
404
1006000
2000
17:03
The power generation will come from the ocean itself.
405
1008000
3000
17:06
And the next generation fiber
406
1011000
2000
17:08
will be simply magic.
407
1013000
2000
17:10
It's far beyond what we currently have.
408
1015000
3000
17:13
So the presence of the power
409
1018000
2000
17:15
and the bandwidth in the environment
410
1020000
2000
17:17
will allow all of these new technologies
411
1022000
2000
17:19
to converge in a manner that is just unprecedented.
412
1024000
3000
17:22
So within five to seven years,
413
1027000
2000
17:24
I see us having
414
1029000
2000
17:26
a capacity to be completely present
415
1031000
2000
17:28
throughout the ocean
416
1033000
2000
17:30
and have all of that connected to the Internet,
417
1035000
2000
17:32
so we can reach many, many folks.
418
1037000
3000
17:35
Delivering the power and the bandwidth into the ocean
419
1040000
3000
17:38
will dramatically accelerate adaptation.
420
1043000
3000
17:41
Here's an example.
421
1046000
2000
17:43
When earthquakes take place, massive amounts
422
1048000
2000
17:45
of these new microbes we've never seen before
423
1050000
2000
17:47
come out of the sea floor.
424
1052000
2000
17:49
We have a way of addressing that,
425
1054000
2000
17:51
a new way of addressing that.
426
1056000
3000
17:54
We've determined from the earthquake activity that you're seeing here
427
1059000
3000
17:57
that the top of that volcano is erupting,
428
1062000
3000
18:00
so we deploy the troops.
429
1065000
2000
18:02
What are the troops? The troops are the autonomous vehicles, of course.
430
1067000
3000
18:05
And they fly into the erupting volcano.
431
1070000
3000
18:08
They sample the fluids coming out of the sea floor
432
1073000
2000
18:10
during an eruption,
433
1075000
2000
18:12
which have the microbes that have never been
434
1077000
2000
18:14
to the surface of the planet before.
435
1079000
2000
18:16
They eject it to the surface where it floats,
436
1081000
2000
18:18
and it is picked up
437
1083000
2000
18:20
by an autonomous airplane,
438
1085000
3000
18:23
and it's brought back to the laboratory
439
1088000
3000
18:26
within 24 hours of the eruption.
440
1091000
2000
18:28
This is doable. All the pieces are there.
441
1093000
3000
18:34
A laboratory: many of you heard what happened
442
1099000
2000
18:36
on 9/7.
443
1101000
2000
18:38
Some doctors in New York City removed
444
1103000
2000
18:40
the gallbladder of a woman in France.
445
1105000
3000
18:44
We could do work on the sea floor that would be stunning,
446
1109000
2000
18:46
and it would be on live TV,
447
1111000
2000
18:48
if we have interesting things to show.
448
1113000
3000
18:51
So we can bring an entirely new telepresence
449
1116000
3000
18:54
to the world, throughout the ocean.
450
1119000
3000
18:57
This -- I've shown you sea floor --
451
1122000
2000
18:59
but so the goal here is real time interaction
452
1124000
2000
19:01
with the oceans from anywhere on earth.
453
1126000
3000
19:06
It's going to be amazing.
454
1131000
3000
19:09
And as I go here,
455
1134000
2000
19:11
I just want to show you what we can bring into classrooms,
456
1136000
3000
19:14
and indeed, what we can bring into your pocket.
457
1139000
3000
19:20
Many of you don't think of this yet,
458
1145000
2000
19:22
but the ocean will be in your pocket.
459
1147000
2000
19:24
It won't be long. It won't be long.
460
1149000
3000
19:28
So let me leave you then
461
1153000
3000
19:31
with a few words
462
1156000
2000
19:33
from another poet, if you'll forgive me.
463
1158000
3000
19:39
In 1943,
464
1164000
2000
19:41
T.S. Eliot wrote the "Four Quartets."
465
1166000
2000
19:43
He won the Nobel Prize for literature
466
1168000
2000
19:45
in 1948.
467
1170000
2000
19:48
In "Little Gidding" he says --
468
1173000
2000
19:50
speaking I think for the human race,
469
1175000
2000
19:52
but certainly for the TED Conference and Sylvia --
470
1177000
3000
19:56
"We shall not cease from exploration,
471
1181000
3000
19:59
and the end of all our exploring
472
1184000
2000
20:01
will be to arrive where we started
473
1186000
2000
20:03
and know the place for the first time,
474
1188000
3000
20:06
arrive through the unknown remembered gate
475
1191000
3000
20:09
where the last of earth left to discover
476
1194000
3000
20:12
is that which was the beginning.
477
1197000
3000
20:15
At the source of the longest river
478
1200000
3000
20:18
the voice of a hidden waterfall
479
1203000
3000
20:21
not known because not looked for,
480
1206000
4000
20:25
but heard, half heard
481
1210000
4000
20:29
in the stillness beneath the waves of the sea."
482
1214000
4000
20:33
Thank you.
483
1218000

ABOUT THE SPEAKER
John Delaney - OceanographerJohn Delaney leads the team that is building a cabled network of deep-ocean sensors that will study, over time and space, the way the ocean's complex processes interact. By networking the ocean to gather data, he's helping to revolutionize ocean science.
Why you should listen
John Delaney studies the physical, chemical and biological interactions found in the mid-ocean ridge system, specifically on the deep-sea volcanoes along the Juan de Fuca Ridge in the northeast Pacific Ocean. It's a complex, changeable world (that's also quite hard to get to). As part of the NSF's Ocean Observatories Initiative, Delaney is spearheading a bold new plan to gather unprecedented amounts of oceanic data.
Starting this year, Delaney and his team at the University of Washington are implanting robotic sensor arrays along the Juan de Fuca Ridge and other ocean sites, on the ocean floor and throughout the water column, all linked to the Internet via submarine electro-optical cables. The system will document and measure once-inaccessible phenomena such as erupting volcanoes, migration patterns, submarine slumps, undersea earthquakes and storms -- and it will feed that data into ever-richer computer models of ocean behavior.
