00:00:04,700 --> 00:00:02,480
hello and welcome to being

2
00:00:07,160 --> 00:00:04,710
with NASA my name is I am in

3
00:00:10,820 --> 00:00:07,170
Argueta and today I am going to prepare one of my

4
00:00:12,980 --> 00:00:10,830
favorite dishes, the Peruvian ceviche.

5
00:00:15,530 --> 00:00:12,990
What many people do not know about NASA is

6
00:00:17,960 --> 00:00:15,540
that we play an important role in

7
00:00:20,920 --> 00:00:17,970
helping to maintain  the health of

8
00:00:23,660 --> 00:00:20,930
fisheries using satellite data

9
00:00:26,599 --> 00:00:23,670
with that scientific data you can

10
00:00:28,820 --> 00:00:26,609
look at something like the color of the ocean and

11
00:00:31,609 --> 00:00:28,830
determine the health and state of

12
00:00:34,190 --> 00:00:31,619
different populations of fish like

13
00:00:36,470 --> 00:00:34,200
this white fish that I am going to use today and

14
00:00:39,470 --> 00:00:36,480
to tell us about all this

15
00:00:41,420 --> 00:00:39,480
laura is with me  lorenzón and scientist of the

16
00:00:43,850 --> 00:00:41,430
oceanic biology and

17
00:00:47,779 --> 00:00:43,860
biogeochemistry program at nasa central office

18
00:00:51,110 --> 00:00:47,789
hello laura how are you now I

19
00:00:53,869 --> 00:00:51,120
know how you are doing very well thanks for

20
00:00:55,790 --> 00:00:53,879
joining us first of all tell me

21
00:00:58,760 --> 00:00:55,800
you like ceviche

22
00:01:02,000 --> 00:00:58,770
I love it my husband prepares it with

23
00:01:04,399 --> 00:01:02,010
mango and it is  absolutely delicious very

24
00:01:07,100 --> 00:01:04,409
good very good so first of all

25
00:01:09,080 --> 00:01:07,110
talking a bit about why nasa

26
00:01:11,630 --> 00:01:09,090
studies the ocean and what does that have to do

27
00:01:13,340 --> 00:01:11,640
with ceviche well you will know that

28
00:01:15,830 --> 00:01:13,350
17 percent of the world population

29
00:01:18,230 --> 00:01:15,840
depends on the ocean for their

30
00:01:20,149 --> 00:01:18,240
daily protein  and we want to make sure

31
00:01:22,399 --> 00:01:20,159
that our marine resources are

32
00:01:24,740 --> 00:01:22,409
being maintained not only for us

33
00:01:26,570 --> 00:01:24,750
but for our future populations and

34
00:01:28,670 --> 00:01:26,580
since the sea covers two thirds of

35
00:01:31,310 --> 00:01:28,680
our planet it is also important to

36
00:01:33,980 --> 00:01:31,320
make sure that we are using it

37
00:01:37,130 --> 00:01:33,990
well and it plays a fundamental role in

38
00:01:38,810 --> 00:01:37,140
our climate  The ocean absorbs heat and

39
00:01:41,389 --> 00:01:38,820
through ocean currents

40
00:01:43,520 --> 00:01:41,399
redistributes it around the rest of the

41
00:01:45,529 --> 00:01:43,530
planet, but as the

42
00:01:47,480 --> 00:01:45,539
climate changes, our ocean also changes, which is

43
00:01:49,340 --> 00:01:47,490
why it is very important to observe it,

44
00:01:51,710 --> 00:01:49,350
because these changes can also

45
00:01:54,440 --> 00:01:51,720
impact fishing and the UNACE mission

46
00:01:57,050 --> 00:01:54,450
in  reality is to understand how

47
00:01:59,630 --> 00:01:57,060
the earth works as a clear system an

48
00:02:01,470 --> 00:01:59,640
entire system if i know that nasa observes

49
00:02:04,860 --> 00:02:01,480
the color of the ocean from it

50
00:02:07,290 --> 00:02:04,870
empty right what does that mean

51
00:02:09,690 --> 00:02:07,300
exactly what you hear what color

52
00:02:12,120 --> 00:02:09,700
is the water the color of our waters

53
00:02:13,650 --> 00:02:12,130
is  impacted by what is dissolved

54
00:02:16,620 --> 00:02:13,660
or what is suspended in it

55
00:02:19,050 --> 00:02:16,630
then the satellites work just

56
00:02:21,900 --> 00:02:19,060
as our eyes work and

57
00:02:24,000 --> 00:02:21,910
we can see if there is something

58
00:02:26,970 --> 00:02:24,010
different in terms of the color of the water

59
00:02:29,480 --> 00:02:26,980
for example if we see a large stain or

60
00:02:32,070 --> 00:02:29,490
large areas of green  We can

61
00:02:35,160 --> 00:02:32,080
assume that this is a

62
00:02:37,410 --> 00:02:35,170
very healthy population of phytoplankton now that with

63
00:02:39,480 --> 00:02:37,420
the phytoplankton, well, the zooplankton and

64
00:02:41,280 --> 00:02:39,490
that he started planting, well, the

65
00:02:42,960 --> 00:02:41,290
small fish and who eats the

66
00:02:44,280 --> 00:02:42,970
small fish at times bigger

67
00:02:47,460 --> 00:02:44,290
then YouTube

68
00:02:48,860 --> 00:02:47,470
you understand more or less how everything is

69
00:02:51,350 --> 00:02:48,870
connected at

70
00:02:53,800 --> 00:02:51,360
other times  We can also see what

71
00:02:56,509 --> 00:02:53,810
we call several red

72
00:02:58,160 --> 00:02:56,519
phytoplankton expansions, which in this

73
00:03:01,220 --> 00:02:58,170
case is toxic because they produce toxins

74
00:03:02,990 --> 00:03:01,230
in coastal areas where many people

75
00:03:04,880 --> 00:03:03,000
go, this can be a problem for

76
00:03:07,309 --> 00:03:04,890
local health not only for people but

77
00:03:09,500 --> 00:03:07,319
also for ecosystems.  how

78
00:03:12,860 --> 00:03:09,510
interesting that the color of the ocean

79
00:03:15,710 --> 00:03:12,870
gives us so much information and what impact does

80
00:03:17,899 --> 00:03:15,720
the observation of the color of the ocean have and the

81
00:03:21,619 --> 00:03:17,909
health of the ecosystems in the

82
00:03:23,839 --> 00:03:21,629
fisheries all by seeing phytoplankton the

83
00:03:25,789 --> 00:03:23,849
fisheries the fish depend on

84
00:03:28,580 --> 00:03:25,799
lotito planto which is the base the base of

85
00:03:30,470 --> 00:03:28,590
the trophic chain and it also helps us

86
00:03:32,660 --> 00:03:30,480
understand where the fish may be

87
00:03:34,670 --> 00:03:32,670
because of course we depend on the

88
00:03:37,360 --> 00:03:34,680
fish that are caught to be able to

89
00:03:39,589 --> 00:03:37,370
consume them and we know that the fish

90
00:03:41,720 --> 00:03:39,599
have are the favorites so

91
00:03:43,520 --> 00:03:41,730
we can use other data such as

92
00:03:45,920 --> 00:03:43,530
sea surface temperature or

93
00:03:47,479 --> 00:03:45,930
altitude  of the sea to know in which areas

94
00:03:50,210 --> 00:03:47,489
maybe the good fish will be

95
00:03:52,580 --> 00:03:50,220
found to get food

96
00:03:55,130 --> 00:03:52,590
all our data is free and

97
00:03:57,110 --> 00:03:55,140
open to the public

98
00:03:59,930 --> 00:03:57,120
therefore we love that people

99
00:04:02,660 --> 00:03:59,940
use the zipi and our users are

100
00:04:04,310 --> 00:04:02,670
very varied from  the scientists who

101
00:04:06,590 --> 00:04:04,320
generate these algorithms and other

102
00:04:08,510 --> 00:04:06,600
research, but also the public

103
00:04:11,210 --> 00:04:08,520
in general, we have non-

104
00:04:13,280 --> 00:04:11,220
profit organizations, private entities, educators,

105
00:04:15,740 --> 00:04:13,290
children, we love it when real people take

106
00:04:19,370 --> 00:04:15,750
advantage of NASA data to

107
00:04:22,099 --> 00:04:19,380
better understand and protect

108
00:04:25,130 --> 00:04:22,109
and use it wisely.  sustainable our

109
00:04:27,860 --> 00:04:25,140
ocean yes it seems like a very

110
00:04:32,060 --> 00:04:27,870
important investigation since we depend so much on the

111
00:04:34,190 --> 00:04:32,070
ocean our ocean is gigantic 70%

112
00:04:37,160 --> 00:04:34,200
of our planet it is not for nothing we call

113
00:04:39,680 --> 00:04:37,170
our planet our blue planet and

114
00:04:42,170 --> 00:04:39,690
we are all interconnected with the

115
00:04:44,300 --> 00:04:42,180
ocean did you know that at least half

116
00:04:46,550 --> 00:04:44,310
of  The oxygen that we breathe comes

117
00:04:48,620 --> 00:04:46,560
from the sea generated by phytoplankton and

118
00:04:50,720 --> 00:04:48,630
other marine algae. It is important

119
00:04:52,970 --> 00:04:50,730
to remember that we are all

120
00:04:55,510 --> 00:04:52,980
interconnected and whatever I

121
00:04:58,719 --> 00:04:55,520
do on land, for example,

122
00:05:00,820 --> 00:04:58,729
where I put my waste or the

123
00:05:03,850 --> 00:05:00,830
fertilizers that I put on the land,

124
00:05:05,710 --> 00:05:03,860
all of that  Somehow or another it

125
00:05:08,080 --> 00:05:05,720
eventually reaches the ocean through

126
00:05:11,200 --> 00:05:08,090
our rivers that connect the continent

127
00:05:13,180 --> 00:05:11,210
to the ocean and from the coastal zone which is

128
00:05:15,610 --> 00:05:13,190
an area where there is a lot of population

129
00:05:17,920 --> 00:05:15,620
that eventually reaches the

130
00:05:20,290 --> 00:05:17,930
open ocean and the ocean played an

131
00:05:20,290 --> 00:05:21,250
important role in  regulating the earth's climate

132
00:05:25,730 --> 00:05:22,460
[Music]

133
00:05:28,010 --> 00:05:25,740
not only absorbs heat and redistributes it

134
00:05:30,230 --> 00:05:28,020
but also absorbs

135
00:05:32,420 --> 00:05:30,240
carbon dioxide from the atmosphere and the fact

136
00:05:34,370 --> 00:05:32,430
that we haven't absorbed that much

137
00:05:37,460 --> 00:05:34,380
carbon dioxide

138
00:05:39,500 --> 00:05:37,470
in the last of the last 100 years has  It has

139
00:05:41,870 --> 00:05:39,510
helped our climate change to

140
00:05:43,670 --> 00:05:41,880
be much slower if in the ocean

141
00:05:46,130 --> 00:05:43,680
our temperatures would be much

142
00:05:47,900 --> 00:05:46,140
higher and in NASA we have been

143
00:05:50,860 --> 00:05:47,910
studying the role that the ocean has

144
00:05:52,790 --> 00:05:50,870
in climate change, especially

145
00:05:55,910 --> 00:05:52,800
trying to understand what is this

146
00:05:58,720 --> 00:05:55,920
connection between human influences  and

147
00:06:01,310 --> 00:05:58,730
how our planet has been changing

148
00:06:03,230 --> 00:06:01,320
and one of the missions we are

149
00:06:06,050 --> 00:06:03,240
working on what is the plantar mission

150
00:06:08,240 --> 00:06:06,060
airshow cloud in evolution and constance or

151
00:06:11,140 --> 00:06:08,250
pace for its acronym in English is going to

152
00:06:13,340 --> 00:06:11,150
help us is a new mission is

153
00:06:15,650 --> 00:06:13,350
hyperspectral what it means is

154
00:06:17,090 --> 00:06:15,660
that we are seeing more colors of the

155
00:06:19,670 --> 00:06:17,100
ocean than we can see right now, that

156
00:06:22,130 --> 00:06:19,680
is, it will be truly revolutionary and it will

157
00:06:24,320 --> 00:06:22,140
allow us to better understand what

158
00:06:24,320 --> 00:06:26,120
type of phytoplankton is there.

159
00:06:31,850 --> 00:06:30,140
Right now it's not, I do

160
00:06:34,610 --> 00:06:31,860
n't know, it's a bit difficult to distinguish

161
00:06:37,370 --> 00:06:34,620
between the two with pace looking towards the

162
00:06:37,370 --> 00:06:40,040
ocean.

163
00:06:48,830 --> 00:06:46,820
so much to do

164
00:06:51,710 --> 00:06:48,840
with getting this fish to

165
00:06:53,570 --> 00:06:51,720
prepare a dish like ceviche and the

166
00:06:55,520 --> 00:06:53,580
satellites again as our

167
00:06:58,370 --> 00:06:55,530
relative is so big and we have so many

168
00:07:01,040 --> 00:06:58,380
oceans come a critical role to

169
00:07:03,110 --> 00:07:01,050
really be able to observe the changes that

170
00:07:05,180 --> 00:07:03,120
occur day by day and those that occur over the

171
00:07:07,100 --> 00:07:05,190
long  term and this is important because it

172
00:07:08,990 --> 00:07:07,110
allows us to avoid being better

173
00:07:10,530 --> 00:07:09,000
prepared for the changes that are

174
00:07:13,140 --> 00:07:10,540
to come

175
00:07:16,110 --> 00:07:13,150
and that is exactly where food security also comes into play.

176
00:07:18,120 --> 00:07:16,120
In

177
00:07:20,160 --> 00:07:18,130
fact, one of the fisheries in Costa

178
00:07:21,690 --> 00:07:20,170
Rica is part of the early adoption program

179
00:07:24,150 --> 00:07:21,700
of the  data from pace which

180
00:07:25,680 --> 00:07:24,160
means that before page launches

181
00:07:28,230 --> 00:07:25,690
they are ready to be able to

182
00:07:31,560 --> 00:07:28,240
incorporate this type of data into

183
00:07:33,420 --> 00:07:31,570
local fisheries and we really

184
00:07:35,280 --> 00:07:33,430
are very lucky to have the

185
00:07:37,980 --> 00:07:35,290
support of scientists and users who

186
00:07:39,930 --> 00:07:37,990
are always pushing the limits of what

187
00:07:43,110 --> 00:07:39,940
that shows and our technology can

188
00:07:44,370 --> 00:07:43,120
do incredible, a lot is being done
