00:00:17,773 --> 00:00:23,011
After 10 days of operations, 
the REMUS continue to shuttle back and forth 
searching for signs of flight AF 447. 

2
00:00:23,512 --> 00:00:29,350
With 3 of these AUV's deployed day and night, 
one of them surfaces on average every eight hours. 

3
00:00:35,965 --> 00:00:41,715
Each time, more than 20 hours of information is brought
to the surface and transferred to the analysts.

00:01:13,150 --> 00:01:18,226
After analyzing sixty-five square kilometres of seabed,
Andy hands over to Dorsey. 

6
00:01:20,337 --> 00:01:24,618
It's midnight. 
For 12 hours she will be the one
looking for signs of airplane wreckage.

7
00:01:26,719 --> 00:01:28,158
She… and Stéphanie. 

8
00:01:28,159 --> 00:01:33,689
Geologist and geophysicist, who belongs to the institute
that takes depth soundings to map the zone. 

9
00:01:34,197 --> 00:01:37,876
She explains to us the different types of images
produced and analyzed for these searches.

ITV Stéphanie Dupré - geophysicist - IFREMER
We need the bathymetry. 

11
00:01:39,477 --> 00:01:41,424
It shows the ups and downs of the seabed. 

12
00:01:41,425 --> 00:01:46,124
And the AUV's are sent over the seabed

13
00:01:46,125 --> 00:01:49,398
to get charts with the highest resolution in fact. 

14
00:01:49,433 --> 00:01:54,410
Not all of the points, in fact, have yet been geo referenced, 
they haven't got their geometry

15
00:01:49,562 --> 00:01:57,143
but it's the best image to detect the anomalies. 

16
00:01:57,144 --> 00:01:59,587
We're not yet losing resolution, 

17
00:01:59,587 --> 00:02:01,266
so we can identify objects. 

18
00:02:01,267 --> 00:02:05,306
In this case, the wreckage from the airplane that we're looking for.

19
00:02:06,659 --> 00:02:11,121
But the images from the REMUS are not the only information
that the analysts have at their disposal. 

20
00:02:11,679 --> 00:02:15,917
To lead the searches, a wide range of specialists
and means have been put together.

21
00:02:17,634 --> 00:02:20,673
Stéphanie takes us to the deck of the Seabed Worker. 

22
00:02:20,674 --> 00:02:24,995
A team there is recovering via satellite the images 
from the deep towed sonar that is deployed on the other ship. 

23
00:02:24,996 --> 00:02:29,872
Better adapted to smoother terrain,
they scan the plains that are present in the zone.

25
00:03:03,645 --> 00:03:06,718
The analysts continue their unceasing work. 

26
00:03:06,719 --> 00:03:12,514
On the Anne Candies and on the SeaBed Worker, 
the team from the BEA review the situation
and coordinate the searches every night. 

27
00:03:25,152 --> 00:03:27,057
The workrate is high. 

28
00:03:27,092 --> 00:03:31,512
Within 10 days all of the initial zone 
should have been covered and analyzed.
