In this episode of the "How to Protect the Ocean" podcast, host Andrew Lewin interviews Dr. Annalisa Bracco, a professor at Georgia Tech specializing in ocean and climate dynamics. The discussion centers around innovative climate solutions, moving away from the typical focus on the negative impacts of climate change.

Key Climate Solutions Discussed:

Sargassum Management:

Problem: Since 2011, there have been significant blooms of sargassum in the tropical Atlantic, impacting beaches in the Caribbean and Gulf of Mexico. These blooms require costly cleanup efforts, amounting to approximately $300 million per year.

Solutions:

    • Sinking Sargassum: Research is being conducted to explore the feasibility of sinking sargassum to sequester carbon. This involves understanding the ecological impacts and ensuring that the carbon captured is not released back into the atmosphere.

    • Biofuel Production: Collaborations with engineers and biologists are underway to convert sargassum into biofuels. One approach involves using black fly larvae, which can efficiently consume sargassum and accumulate lipids for biofuel extraction.

    • Bricks from Sargassum: A small business in Mexico is creating bricks from dried sargassum, which are reported to be more resilient to storms than traditional building materials.

Coral Reef Connectivity:

    • Dr. Bracco's team is using machine learning to study the connectivity among coral reefs, which is crucial for understanding how larvae disperse and how healthy ecosystems can support one another.

    • The research highlights the dynamic nature of coral ecosystems, particularly in the Pacific, where certain areas can recover from bleaching events due to the exchange of larvae. In contrast, the Atlantic faces challenges due to pollution and overfishing, which hinder recovery.

Interdisciplinary Collaboration:

    • The episode emphasizes the importance of interdisciplinary work in addressing climate issues. Dr. Bracco collaborates with experts from various fields, including biology, engineering, and computer science, to develop comprehensive solutions to climate challenges.

Overall, the episode provides a hopeful perspective on climate solutions, showcasing innovative approaches to managing ocean health and addressing the impacts of climate change.

00:00:00,088 --> 00:00:03,391
Look, I get it. We're probably tired of hearing about

2
00:00:03,431 --> 00:00:06,574
all the doom and gloom surrounding climate change, all the consequences of

3
00:00:06,614 --> 00:00:10,017
climate change and all the money that's involved in

4
00:00:10,137 --> 00:00:13,380
climate change. Like I know Canadians, we as Canadians are sick of

5
00:00:13,420 --> 00:00:17,004
hearing about carbon taxes and all the money that we have to pay as

6
00:00:17,404 --> 00:00:20,747
out of pocket to help climate change. However, today

7
00:00:20,787 --> 00:00:24,129
we're going to switch it up a little bit. We're going to talk about climate solutions, no money

8
00:00:24,269 --> 00:00:27,671
from us, no carbon tax, no taxes at all. We're

9
00:00:27,711 --> 00:00:31,113
just going to focus on climate solutions. And today on

10
00:00:31,133 --> 00:00:34,535
the program, we have Dr. Annalisa Bracco, who is a professor and

11
00:00:34,575 --> 00:00:37,797
associate chair for research at Georgia Tech School of

12
00:00:37,917 --> 00:00:41,078
Earth and Atmospheric Sciences, specializing in

13
00:00:41,318 --> 00:00:44,540
ocean and climate dynamics, not only is she

14
00:00:44,600 --> 00:00:48,484
specializing in ocean climate dynamics. She also has experience

15
00:00:48,544 --> 00:00:52,047
working out in space and she talks about how familiar things

16
00:00:52,228 --> 00:00:55,791
are in space as they are into the ocean. We're going to hear all

17
00:00:55,851 --> 00:01:00,075
about that and her projects as she's been collaborating with a number of different engineers

18
00:01:00,195 --> 00:01:03,778
and scientists and business people on climate

19
00:01:03,798 --> 00:01:07,101
solutions on this episode of the How to Protect the Ocean podcast. Let's

20
00:01:07,121 --> 00:01:11,962

36
00:02:03,113 --> 00:02:06,614
get into the episode with Dr. Annalisa Bracco, who is a professor and

37
00:02:06,654 --> 00:02:09,955
associate chair for research at Georgia Tech School of

38
00:02:10,015 --> 00:02:13,315
Earth and Atmospheric Sciences, specializing in ocean

39
00:02:13,435 --> 00:02:16,736
and climate dynamics. And as I mentioned before, she

40
00:02:16,776 --> 00:02:20,037
was like a physicist that looked at space and looked at the

41
00:02:20,397 --> 00:02:23,898
how galaxies were formed and how planets were formed and modeling

42
00:02:23,938 --> 00:02:27,500
all the stuff around there and how similar space is and modeling space is

43
00:02:27,560 --> 00:02:30,744
compared to the ocean. Very, very interesting. We talk a lot

44
00:02:30,764 --> 00:02:34,048
about climate solutions. We talk a lot about how she was told by

45
00:02:34,088 --> 00:02:37,232
her own father that you wouldn't do

46
00:02:37,272 --> 00:02:40,396
well in physics because you're a woman. And we'll see what happens with

47
00:02:40,436 --> 00:02:43,920
that. She became quite interested in looking after

48
00:02:43,980 --> 00:02:47,622
things about physics and pursuing all things surrounding physics,

49
00:02:48,003 --> 00:02:51,483
and she is here right now to talk about her career,

50
00:02:51,523 --> 00:02:55,104
to talk about climate solutions, and why she switched from just modeling

51
00:02:55,144 --> 00:02:58,685
climate change to climate solutions. We're going to talk about that today.

52
00:02:59,085 --> 00:03:02,206
Enjoy the interview with Dr. Annalisa Bracco, and

53
00:03:02,246 --> 00:03:05,527
I'll talk to you after. Hi, Annalisa. Welcome to

54
00:03:05,667 --> 00:03:09,128
the How to Protect the Ocean podcast. Are you ready to talk about ocean

55
00:03:09,188 --> 00:03:12,799
climate solutions? Absolutely. Love

56
00:03:12,859 --> 00:03:16,501
it. I love it. I'm really excited about this episode because a

57
00:03:16,561 --> 00:03:19,942
lot of the times when we talk about climate change in the ocean, we really focus on

58
00:03:19,962 --> 00:03:23,284
the doom and gloom. We don't talk a lot about solutions. And today,

59
00:03:23,304 --> 00:03:26,906
we're going to be talking about some of those solutions. A lot of it is experimental. A

60
00:03:26,966 --> 00:03:30,127
lot of it is in the research phases. But it's really great to be

61
00:03:30,167 --> 00:03:33,269
able to look at hope down the way. And

62
00:03:33,309 --> 00:03:36,870
I think that's what we need a little bit in today's world. We need a lot of hope. So

63
00:03:37,090 --> 00:03:40,472
I'm looking forward to being able to discuss that with you, Annalisa. But before we do,

64
00:03:44,554 --> 00:03:48,437
Absolutely. So my name is Annalisa Bracco. I'm a professor

65
00:03:48,517 --> 00:03:53,619
at Georgia Tech in climate and oceanography. My

66
00:03:53,739 --> 00:03:57,401
background is in physics. So my degree, my

67
00:03:57,441 --> 00:04:00,683
bachelor degree, was in theoretical physics. And I

68
00:04:00,943 --> 00:04:05,088
got that in Italy at the University of Turin. And

69
00:04:05,148 --> 00:04:09,149
then I did a master

70
00:04:09,189 --> 00:04:12,330
thesis or research work looking at the formation of

71
00:04:12,410 --> 00:04:16,671
galaxies. And from that, I

72
00:04:16,991 --> 00:04:20,272
entered in a PhD to study the role of

73
00:04:20,432 --> 00:04:25,114
vortices in the formation of planets. And

74
00:04:25,174 --> 00:04:29,075
I do all of that using numerical models. And

75
00:04:29,115 --> 00:04:32,656
then after a couple of papers on the planets,

76
00:04:33,373 --> 00:04:36,895
and how they form after the star has

77
00:04:37,075 --> 00:04:40,237
exploded, has formed. So we have the sun, we have a proton nebula, we

78
00:04:40,257 --> 00:04:43,739
need to figure out how we aggregate stuff to

79
00:04:43,779 --> 00:04:48,162
get to the planet. After doing that, I

80
00:04:48,202 --> 00:04:52,064
was essentially asked by my advisor to get

81
00:04:52,545 --> 00:04:56,027
closer to our planet and work

82
00:04:56,167 --> 00:04:59,809
possibly in the ocean or in the atmosphere, because

83
00:04:59,849 --> 00:05:03,387
he was kind of switching research. The

84
00:05:03,447 --> 00:05:06,848
equations that describe the motion of the

85
00:05:06,908 --> 00:05:10,068
gas around the star or of the

86
00:05:10,168 --> 00:05:13,969
oceans are the same. You may make very different

87
00:05:14,029 --> 00:05:17,250
approximations, but at the end of the game, the

88
00:05:17,350 --> 00:05:20,590
players, the big players are exactly the same. Because when you

89
00:05:20,630 --> 00:05:23,771
have a star and you have a nebula around, what happens is that

90
00:05:23,811 --> 00:05:27,651
the nebula is rotating around the star. So

91
00:05:27,671 --> 00:05:32,612
you have rotation. And then you also have stratification. Because

92
00:05:32,772 --> 00:05:36,533
all the gas and the heavy, the gas it's all around, and

93
00:05:36,633 --> 00:05:39,794
instead the heavy stuff, so all the dust that forms after the

94
00:05:39,834 --> 00:05:43,755
star explosion, coalesce in the center. And

95
00:05:43,795 --> 00:05:47,836
so you have a thin layer of a dense object

96
00:05:47,956 --> 00:05:51,097
that is rotating. And that's really what the ocean is,

97
00:05:51,517 --> 00:05:56,179
is a relatively thin layer on a big object,

98
00:05:56,279 --> 00:06:00,012
which is rotating. And so really, the equations and

99
00:06:00,052 --> 00:06:04,035
the forces at play are very similar. So it was a relatively simple

100
00:06:04,115 --> 00:06:07,337
switch. I love to sail. I love the

101
00:06:07,417 --> 00:06:11,160
ocean. And so for my side, it was very easy

102
00:06:11,320 --> 00:06:14,682
to pick the ocean against the atmosphere. I ended up

103
00:06:14,722 --> 00:06:19,231
also working on the atmosphere. I have nothing against the atmosphere. But

104
00:06:19,551 --> 00:06:22,793
at the time I said ocean and that stick with me

105
00:06:22,873 --> 00:06:26,095
and I definitely do more research related to the ocean that

106
00:06:28,317 --> 00:06:31,939
Phenomenal. I love that because a lot of the times when you

107
00:06:31,999 --> 00:06:35,341
hear people talk about space, like say government talks

108
00:06:35,381 --> 00:06:38,583
about space or you hear like SpaceX or whatever and we're like we want

109
00:06:38,603 --> 00:06:42,105
to go to space, we want all these billionaires are wanting to go to space and stuff and explore

110
00:06:42,165 --> 00:06:45,401
space. A lot of times, like, well, let's

111
00:06:45,441 --> 00:06:49,662
forget about space. Let's focus on the ocean. It seems very divisive. It

112
00:06:49,702 --> 00:06:52,903
seems very like people are pitting one against the other. But why can't we

113
00:06:52,963 --> 00:06:56,984
do both? And I love the fact that you have the similarities in

114
00:06:57,004 --> 00:07:00,605
terms of the equation and modeling the ocean and

115
00:07:00,805 --> 00:07:04,646
out in space and formation of galaxies. And they're actually

116
00:07:04,666 --> 00:07:07,907
all similar. So we're here arguing, like, let's spend less money

117
00:07:07,967 --> 00:07:11,868
on space. Let's spend more money on the ocean, which I get. But

118
00:07:11,888 --> 00:07:15,631
in reality, maybe some of the models that were used for

119
00:07:15,691 --> 00:07:18,913
space can be used for the ocean and vice versa. It's just a matter of

120
00:07:18,973 --> 00:07:22,075
finding those similarities. So I love the fact that you've crossed over that. But I

121
00:07:22,135 --> 00:07:25,317
have to ask to go back a little bit and

122
00:07:25,497 --> 00:07:29,299
talk about your interest in in physics as

123
00:07:29,339 --> 00:07:33,281
a young woman, right? What got you into learning

124
00:07:33,361 --> 00:07:37,163
about physics? That's not something you hear every day. And to

125
00:07:37,183 --> 00:07:40,405
be honest, and this is a feat to you, is as

126
00:07:40,445 --> 00:07:43,567
a woman, you don't see a lot of physicists come out,

127
00:07:43,667 --> 00:07:46,989
right? You don't see a lot of women being known as being

128
00:07:47,029 --> 00:07:50,211
physicists. So how

129
00:07:53,253 --> 00:07:58,209
I was not very much encouraged for a while. That's

130
00:07:58,249 --> 00:08:02,811
a very different story. So my dad is

131
00:08:07,374 --> 00:08:11,037
Yes. My dad only managed to get through middle

132
00:08:11,077 --> 00:08:14,279
school. Wow. He

133
00:08:14,319 --> 00:08:17,841
was born just before World War II, so

134
00:08:17,881 --> 00:08:21,563
there was kind of no money. He had to go to work, and he actually managed

135
00:08:21,603 --> 00:08:24,985
to get through middle school just because some teacher really

136
00:08:25,146 --> 00:08:28,254
pushed him. push his father to let him do it,

137
00:08:28,575 --> 00:08:32,595
because the problem was really the family needed him. But

138
00:08:32,656 --> 00:08:36,416
then he got into the army, because

139
00:08:36,436 --> 00:08:41,097
that was a safe job and the job that pays you every month, when

140
00:08:41,137 --> 00:08:44,758
he was very young. And from there, he... Is this

141
00:08:49,760 --> 00:08:53,040
And essentially he got in the, what here will

142
00:08:53,080 --> 00:08:57,773
be the Corps of Engineering. Okay,

143
00:08:57,873 --> 00:09:01,395
yeah. And so they were building bridges, they

144
00:09:01,435 --> 00:09:05,137
were rebuilding the whole infrastructure for Italy and especially train

145
00:09:05,177 --> 00:09:08,819
bridges for the rail system. And

146
00:09:09,719 --> 00:09:14,502
he started studying on his own. And then in

147
00:09:14,882 --> 00:09:18,284
1969, there was the opportunity for people that didn't have a high school degree

148
00:09:18,424 --> 00:09:21,706
to take an exam and

149
00:09:22,006 --> 00:09:25,428
get through and if they pass and enroll at

150
00:09:28,244 --> 00:09:31,686
Wow. How old was he in

151
00:09:36,149 --> 00:09:39,551
Yeah. OK. So fairly late to think about university, but

152
00:09:41,633 --> 00:09:44,995
He was already married. My mom really pushed him to do that.

153
00:09:45,535 --> 00:09:49,078
He had this passion for physics. He had read and learned

154
00:09:49,198 --> 00:09:52,660
a lot on his own, just reading books and things. And

155
00:09:52,760 --> 00:09:57,220
so he entered. So he passed. But

156
00:09:57,240 --> 00:10:00,382
then decided to stay where he was and

157
00:10:00,462 --> 00:10:03,643
not go to university because that would have delay having a

158
00:10:03,703 --> 00:10:06,724
family and things like that. So I was born a

159
00:10:07,585 --> 00:10:10,846
couple of years later, in fact. But at the same

160
00:10:10,906 --> 00:10:14,127
time, that allowed him to advance in

161
00:10:14,147 --> 00:10:17,389
the career in the army as if he had a

162
00:10:17,429 --> 00:10:20,550
high school degree. And so he was

163
00:10:20,650 --> 00:10:23,931
able to get into the Military Academy for the Corps of

164
00:10:23,991 --> 00:10:27,123
Engineering and teach applied physics. So I

165
00:10:27,183 --> 00:10:30,545
grew up with a father that would teach us physics every

166
00:10:30,605 --> 00:10:34,928
single opportunity he had. So I do remember, not

167
00:10:34,968 --> 00:10:38,330
too fondly, those trips where he,

168
00:10:38,630 --> 00:10:42,812
you know, any kind of something

169
00:10:42,852 --> 00:10:46,174
that was moving in the car, and we would have to go through

170
00:10:46,214 --> 00:10:51,738
the centrifugal acceleration and always

171
00:10:52,038 --> 00:10:55,780
get to calculate, you know, what is the minimum

172
00:10:57,026 --> 00:11:00,707
What is the ideal distance for a satellite to be

173
00:11:00,807 --> 00:11:04,508
in a geostationary position? And

174
00:11:05,368 --> 00:11:08,508
I was six or seven, and my brother was younger. And

175
00:11:08,608 --> 00:11:11,809
so, you know, he always came to me to do all those

176
00:11:11,829 --> 00:11:15,670
calculations. And of course, I was doing them wrongly. I mean, I was six

177
00:11:15,730 --> 00:11:18,951
or seven. So he decided I was really not

178
00:11:19,011 --> 00:11:22,381
talented for physics. But

179
00:11:22,521 --> 00:11:25,844
it got me to think a lot about that. And it got me then

180
00:11:26,384 --> 00:11:30,107
later on, we start talking about general relativity. He was, he

181
00:11:30,147 --> 00:11:34,070
had read everything about that too. I mean, the original textbooks

182
00:11:34,170 --> 00:11:37,672
by Einstein. And so

183
00:11:37,792 --> 00:11:41,335
I got to be interested in that. And

184
00:11:41,375 --> 00:11:44,877
then one day he told me, but you are a woman and

185
00:11:44,977 --> 00:11:48,580
women are not logic. And so you cannot understand physics.

186
00:11:49,185 --> 00:11:52,669
I got so mad that I ended up

187
00:11:52,729 --> 00:11:56,214
saying, well, I'll show you. And that's pretty

188
00:11:58,897 --> 00:12:02,040
So it was more of like to prove your dad wrong to

189
00:12:02,080 --> 00:12:05,203
say hey, you know what you've been teaching me all these years I picked up

190
00:12:05,243 --> 00:12:08,566
a few things and I've got an interest in it. I'm gonna do it. I like that.

191
00:12:08,806 --> 00:12:12,169
I like that. That's really interesting And then so then from

192
00:12:12,189 --> 00:12:15,512
there the so that means, you know high school, you know You

193
00:12:18,154 --> 00:12:21,577
I know I took very little physics in high school I actually went for

194
00:12:21,617 --> 00:12:24,760
classic literature. I was very very talented in literature and

195
00:12:24,820 --> 00:12:28,278
writing so I did Greek and Latin for

196
00:12:28,338 --> 00:12:31,799
five years and just a tiny bit of physics, but I

197
00:12:31,879 --> 00:12:36,101
enjoyed that tiny bit. And then I really

198
00:12:36,261 --> 00:12:40,043
went, I mean, I really did physics as an undergraduate

199
00:12:40,143 --> 00:12:44,844
because I wanted to show him that I could do it. And

200
00:12:44,884 --> 00:12:48,066
in fact, I finished and before getting into

201
00:12:48,106 --> 00:12:51,707
a PhD, I took a year off and I went to do classic literature

202
00:12:51,807 --> 00:12:55,291
as a bachelor degree. and decided that

203
00:12:55,631 --> 00:13:00,753
I was getting bored because I was missing research. My

204
00:13:00,793 --> 00:13:04,175
last year as an undergraduate in Italy,

205
00:13:04,215 --> 00:13:07,297
it's essentially equivalent of a master, you have to work on a thesis and I

206
00:13:07,417 --> 00:13:10,478
really enjoyed the research part. So I

207
00:13:10,538 --> 00:13:13,600
went back and I tried to enter in

208
00:13:13,660 --> 00:13:17,222
a PhD, which is hard in Italy, just percent to advise because

209
00:13:17,282 --> 00:13:22,116
it's an exam that you have to pass nationally. So

210
00:13:22,136 --> 00:13:25,778
there are very few positions open. Things have changed, but

211
00:13:25,978 --> 00:13:29,140
when I did it, it was like that. And

212
00:13:29,380 --> 00:13:32,462
I remember calling my dad and saying that I

213
00:13:32,502 --> 00:13:35,804
was dropping a job offer that I had received because

214
00:13:35,844 --> 00:13:39,065
I wanted to first try to get into a PhD. And he told me,

215
00:13:39,085 --> 00:13:42,367
you are good, but not that good. I was like, well,

216
00:13:44,142 --> 00:13:47,585
Do you think he knew what he was doing? Because the first time

217
00:13:47,705 --> 00:13:50,968
he said no, and then you're like, no, I'm going to show him. And now

218
00:13:51,008 --> 00:13:54,371
he's telling you, no, you're good. You proved his point, but

219
00:13:55,892 --> 00:13:59,456
No, when I got in and I actually placed first

220
00:14:00,617 --> 00:14:03,939
of the five people that were admitted that year, I

221
00:14:04,040 --> 00:14:07,563
called him. He's the first person I called and I said, I'm

222
00:14:07,843 --> 00:14:11,102
in. And he told me, well, how many got in, like

223
00:14:11,222 --> 00:14:14,603
five, and how did you place first, and how many other

224
00:14:14,663 --> 00:14:17,904
women? None. It was completely by chance. At that

225
00:14:18,024 --> 00:14:21,365
point, like the following year, there were three women out of five, so

226
00:14:23,486 --> 00:14:26,647
Yeah, yeah, or the mix at that point. I mean, you know, the

227
00:14:26,707 --> 00:14:30,028
numbers are so small. You start with 70 people, you have to get down

228
00:14:30,088 --> 00:14:33,289
to five. Some years will be female, some years will be male.

229
00:14:34,133 --> 00:14:37,374
But he was very impressed by that. He was really impressed by

230
00:14:37,414 --> 00:14:41,876
the, you know, you put four guys

231
00:14:43,956 --> 00:14:47,418
Yeah. You're like, you're ahead of four guys. You're like, Hey, what? Remember

232
00:14:52,259 --> 00:14:55,480
That's fantastic. So you get into a PhD program and

233
00:14:55,520 --> 00:14:59,022
you're still doing, this is not the galaxy

234
00:15:00,622 --> 00:15:03,721
Yeah. I started looking on, I started working on, uh, of

235
00:15:04,201 --> 00:15:07,582
formation of planets. And then I switched to

236
00:15:11,103 --> 00:15:15,124
And again- You switched to oceanography while you're doing

237
00:15:15,924 --> 00:15:19,725
Okay, because you're a supervisor. Again, vortices

238
00:15:19,865 --> 00:15:23,226
in the ocean are fundamental for oceanography, so

239
00:15:27,323 --> 00:15:30,825
But I'm sure, and you say very easy, I

240
00:15:30,905 --> 00:15:34,086
say no way, because just what you're probably working with

241
00:15:34,226 --> 00:15:37,807
on the regular, I wouldn't be able to understand because you sound

242
00:15:37,867 --> 00:15:42,729
much more intelligent than I am in physics. But

243
00:15:42,849 --> 00:15:46,350
going from space to ocean, just from

244
00:15:46,410 --> 00:15:49,892
a mind perspective, one, you're exploring the

245
00:15:49,932 --> 00:15:53,755
vastness of space where you could probably make a

246
00:15:53,815 --> 00:15:57,477
number of different discoveries. You could probably do a lot of wonderful things.

247
00:15:57,837 --> 00:16:01,718
Now, obviously, you can still do discoveries because there's still a vastness to the ocean. But

248
00:16:01,758 --> 00:16:05,120
it seems like there's a little bit more limitation. And I say limitation by

249
00:16:05,140 --> 00:16:08,541
a squeeze, right? But in comparison, was

250
00:16:08,581 --> 00:16:11,742
there a shift being like, why am I going from space to ocean? Did

251
00:16:13,363 --> 00:16:17,245
No. I love the space part because

252
00:16:17,365 --> 00:16:20,566
I love just

253
00:16:20,606 --> 00:16:24,038
the idea. you

254
00:16:24,078 --> 00:16:27,600
are learning how everything formed and all of that. But

255
00:16:27,660 --> 00:16:30,881
I must say that because I

256
00:16:30,921 --> 00:16:34,663
was already working with models, the possibility of

257
00:16:34,743 --> 00:16:38,224
applying it to something where I could have observations or

258
00:16:38,244 --> 00:16:41,305
I could at least solve actual problem, it became a

259
00:16:41,365 --> 00:16:44,827
little bit less abstract. And we

260
00:16:44,847 --> 00:16:48,208
were also at the time where climate change was starting to become

261
00:16:48,248 --> 00:16:51,510
a problem. So no, I

262
00:16:51,550 --> 00:16:54,784
was very pleased to do

263
00:16:54,844 --> 00:16:59,025
that switch. The fact that I had something to

264
00:16:59,225 --> 00:17:02,546
anchor what I was doing and to see the

265
00:17:02,586 --> 00:17:06,667
application of what I was doing directly, it was

266
00:17:12,508 --> 00:17:15,729
So I finished my PhD in 2000. So I started in 1997. I finished in 2000. So I made

267
00:17:22,126 --> 00:17:25,467
Right. So I was, the reason why I asked was more because

268
00:17:25,487 --> 00:17:28,868
of the, you mentioned climate was, we were really starting to, we

269
00:17:28,888 --> 00:17:32,089
were starting to focus more on climate at that point. And that's true.

270
00:17:32,109 --> 00:17:35,531
I remember starting to learn, I went to university, I did my undergrad in

271
00:17:36,011 --> 00:17:39,212
97 to 2001. And that's when I started to really find out more

272
00:17:39,232 --> 00:17:42,733
and more about climate. And even though it wasn't necessarily being

273
00:17:43,153 --> 00:17:46,734
talked about in the public eye as much up maybe

274
00:17:46,774 --> 00:17:49,929
until the earlier 2000s, but It was in

275
00:17:50,469 --> 00:17:53,972
the academic sort of circles. It was being discussed quite

276
00:17:53,992 --> 00:17:57,355
a bit. We knew that there was going to be problems 10 to 20 years. And

277
00:17:57,715 --> 00:18:01,018
surprise, surprise, we have problems 10 to 20 years later and so

278
00:18:01,058 --> 00:18:04,508
forth, even 30 years later. At

279
00:18:04,548 --> 00:18:08,270
that point, though, did you see, focusing

280
00:18:08,310 --> 00:18:11,933
a little bit on climate, knowing where this is going, did you

281
00:18:12,873 --> 00:18:16,135
really understand how, one,

282
00:18:16,215 --> 00:18:20,398
good for your career this would be because you're working in climate, but also understand

283
00:18:20,858 --> 00:18:24,420
the depths of the destruction that climate change

284
00:18:26,902 --> 00:18:30,064
No, not at the time. Also because I was

285
00:18:30,144 --> 00:18:33,859
a student and I'm always being kind of optimistic, like

286
00:18:33,939 --> 00:18:37,540
I just, it's really curiosity what at the end drives me.

287
00:18:39,281 --> 00:18:42,522
And the other thing that I would say the ocean was bringing was the

288
00:18:43,023 --> 00:18:46,304
possibility to really work at the intersection of physics, but

289
00:18:46,364 --> 00:18:49,686
also chemistry and biology, which is something that I had in me

290
00:18:49,866 --> 00:18:53,748
already from the university, the undergraduate time.

291
00:18:53,808 --> 00:18:57,829
So I wanted to be able to do something that

292
00:18:57,869 --> 00:19:02,019
was more interdisciplinary. So I

293
00:19:02,079 --> 00:19:05,600
didn't see it coming as much.

294
00:19:06,521 --> 00:19:10,562
And also, I would say, we

295
00:19:10,582 --> 00:19:14,243
started having satellites and having really good information about

296
00:19:14,323 --> 00:19:17,805
climate only in the 80s. So we were just 15 years

297
00:19:18,365 --> 00:19:21,746
or less than 20 years in. The trends were not there yet.

298
00:19:22,106 --> 00:19:25,326
The record was just too short. But we were coming out of

299
00:19:25,466 --> 00:19:29,707
the biggest El Nino in the century, the 1996 event,

300
00:19:30,347 --> 00:19:33,548
and also what that meant for population all

301
00:19:33,648 --> 00:19:37,809
over, from India to Africa. So there

302
00:19:37,849 --> 00:19:41,590
was a lot of, you know, we can understand more,

303
00:19:42,050 --> 00:19:45,490
we need to understand more, and we can also be useful

304
00:19:45,530 --> 00:19:49,551
to society. That was interesting,

305
00:19:49,651 --> 00:19:53,372
and it was also what drove me into the field.

306
00:19:53,849 --> 00:19:58,792
Interesting. Okay, cool. Now, after which you finish

307
00:19:58,812 --> 00:20:02,194
up your PhD, what happened next? Where did

308
00:20:05,776 --> 00:20:08,958
I did a postdoc. I came to the US for the first time for

309
00:20:08,978 --> 00:20:12,160
a long period. I did a postdoc at the Woods

310
00:20:12,180 --> 00:20:15,842
Hole Oceanographic Institution in Massachusetts. And

311
00:20:15,902 --> 00:20:19,384
then I went back to Italy and I worked at

312
00:20:19,544 --> 00:20:23,485
UNESCO for three and a half years. UNESCO

313
00:20:23,565 --> 00:20:26,646
has one research center, which is located in

314
00:20:26,726 --> 00:20:30,408
Italy, it's called the International Center for Theoretical Physics, and they were growing

315
00:20:38,793 --> 00:20:43,475
And then I came back to the United States, and in December

316
00:20:52,011 --> 00:20:55,492
Yeah, I had another year at WUTSOL in

317
00:20:58,733 --> 00:21:01,774
So I know a lot of it was research-based, but working for an

318
00:21:01,854 --> 00:21:05,336
organization like UNESCO, especially in Italy, where I feel like Italy

319
00:21:05,416 --> 00:21:08,617
is a bit of a headquarters for a lot of

320
00:21:08,877 --> 00:21:12,338
international organizations, UN, FAO

321
00:21:12,398 --> 00:21:15,779
is there as well, UNESCO obviously has an

322
00:21:15,839 --> 00:21:19,729
office there, it's a pretty big hub for international

323
00:21:19,829 --> 00:21:23,151
type of work and research. What

324
00:21:23,471 --> 00:21:26,873
made you decide to pursue one kind

325
00:21:26,913 --> 00:21:30,115
of a little bit, get away a little bit of that and not work directly for

326
00:21:30,175 --> 00:21:33,798
them, but also move into an academic position?

327
00:21:35,059 --> 00:21:38,441
Well, there were a number of

328
00:21:39,905 --> 00:21:44,826
work-related, personnel-related, a lot of things that got together. But

329
00:21:45,046 --> 00:21:48,867
I was happy to get to a faculty position because

330
00:21:48,927 --> 00:21:53,328
I wanted to work more directly with students. And

331
00:21:54,809 --> 00:21:58,089
I truly enjoy advising. So

332
00:21:58,149 --> 00:22:01,770
I wanted to have that opportunity and build

333
00:22:01,850 --> 00:22:05,962
a group and kind of give

334
00:22:06,042 --> 00:22:09,443
also back to the new generations, you know, the

335
00:22:09,463 --> 00:22:13,684
passion, the kind of curiosity that I have. And so

336
00:22:13,704 --> 00:22:17,125
that for me was important. I love it.

337
00:22:17,325 --> 00:22:20,946
And in Trieste, you can do a little bit of that. And you do a lot of that with

338
00:22:22,146 --> 00:22:26,107
students from developing countries, but are usually shorter interactions,

339
00:22:26,247 --> 00:22:29,393
like they come for a few months, and they go. So it's a little bit

340
00:22:29,833 --> 00:22:32,934
It's not like a three to five year, depending on what they're doing, whether a

341
00:22:32,954 --> 00:22:36,415
master's or PhD, or even a postdoc, where you can, you really get

342
00:22:36,475 --> 00:22:39,916
into a mentorship role with that

343
00:22:39,996 --> 00:22:43,017
student. And I think that really, yeah, I agree. I think that's a

344
00:22:43,057 --> 00:22:46,218
really great feature for academia. And now you've

345
00:22:46,258 --> 00:22:49,559
been doing that since, at Georgia Tech, since then. That's

346
00:22:52,755 --> 00:22:56,138
Yeah, no, another thing that really brought me to Georgia

347
00:22:56,178 --> 00:22:59,521
Tech that I enjoyed very much was the fact that there was a lot of go

348
00:22:59,561 --> 00:23:03,524
and a lot of attention for interdisciplinary

349
00:23:03,564 --> 00:23:06,667
projects. So there was a lot of support for that. And

350
00:23:06,727 --> 00:23:09,930
so I enjoyed that from the beginning because I

351
00:23:09,970 --> 00:23:13,132
started working in collaboration with people in biology, School of

352
00:23:13,192 --> 00:23:16,495
Physics, and College of Computing, and now

353
00:23:21,111 --> 00:23:24,252
brought me here and kept me

354
00:23:24,352 --> 00:23:28,513
here. Georgia Tech is a great school. It's a big school. It's

355
00:23:28,553 --> 00:23:31,793
got a lot to go by. It's very popular. Now, how

356
00:23:31,813 --> 00:23:35,754
did you feel about coming from Italy, where you have European football,

357
00:23:35,794 --> 00:23:39,055
and you come to Georgia Tech, where you have American football, which is pretty big

358
00:23:42,096 --> 00:23:45,376
I don't watch American football. I don't understand it.

359
00:23:48,297 --> 00:23:52,464
I used to. Okay, I still watch the

360
00:23:53,645 --> 00:23:56,847
Yeah, of course. Yeah, of course. Yeah, that's awesome. Okay, I

361
00:23:57,207 --> 00:24:00,689
had to push that in there because I feel like that was a big change

362
00:24:02,070 --> 00:24:06,252
Now, is there a lot of difference between doing

363
00:24:06,372 --> 00:24:09,714
a PhD in Italy and

364
00:24:09,734 --> 00:24:13,217
then mentoring PhD students and graduate students

365
00:24:16,994 --> 00:24:20,957
Yes and no, in the sense that the Italian PhD

366
00:24:21,017 --> 00:24:24,439
comes after an undergraduate, and

367
00:24:24,519 --> 00:24:27,781
now it's different, but anyways, it's three plus two

368
00:24:27,841 --> 00:24:31,023
years even now. So it's five years and essentially you

369
00:24:31,043 --> 00:24:34,666
already do the equivalent of a master. So

370
00:24:34,846 --> 00:24:38,888
when you start your PhD, it's shorter, it's three years, and

371
00:24:39,009 --> 00:24:43,471
it's really focused on research. There are almost no classes. While

372
00:24:43,591 --> 00:24:46,947
here, it's longer and is essentially what

373
00:24:46,967 --> 00:24:50,869
in Europe or what in Italy would be the master plus a PhD. With

374
00:24:50,929 --> 00:24:54,871
five years and the first couple of years, there is a substantial

375
00:24:54,911 --> 00:24:58,633
amount of coursework that you have to take. So

376
00:24:58,693 --> 00:25:02,695
in that sense, it's just putting together the two things. So it's different,

377
00:25:02,855 --> 00:25:06,256
but at the end, it's- Same amount of time, just different way

378
00:25:07,617 --> 00:25:11,299
Yeah. It's interesting because I live in Canada and the research thesis

379
00:25:11,877 --> 00:25:15,358
for a PhD is very much research-based. You do some courses

380
00:25:15,398 --> 00:25:18,799
if you need it, but there are students who don't.

381
00:25:18,879 --> 00:25:22,119
They may do one or two courses if they need it, but it's very different there.

382
00:25:22,159 --> 00:25:25,600
So it's interesting to hear the European versus North

383
00:25:25,640 --> 00:25:28,941
American and the differences and similarities from there.

384
00:25:29,641 --> 00:25:33,042
Now, since you've been at Georgia Tech, it's been almost 20 years,

385
00:25:33,202 --> 00:25:36,562
I guess, since you've been there, your

386
00:25:36,822 --> 00:25:40,697
work has stayed on oceans and climate. How

387
00:25:40,737 --> 00:25:43,819
has that evolved over the last 20 years for you and just sort of

388
00:25:44,199 --> 00:25:47,540
how we've been involving as a society as well?

389
00:25:47,981 --> 00:25:51,402
I think we definitely shift from just

390
00:25:51,682 --> 00:25:55,184
understanding the climate system and

391
00:25:55,524 --> 00:25:59,466
trying to attribute the changes in the climate system to

392
00:26:00,286 --> 00:26:03,548
greenhouse gas concentrations increasing to

393
00:26:04,188 --> 00:26:07,350
aerosol increasing initially and now decreasing and so on

394
00:26:07,470 --> 00:26:11,471
to really trying to find solutions to the problems and

395
00:26:12,151 --> 00:26:15,335
to working much more towards adaptation and

396
00:26:15,375 --> 00:26:20,020
mitigation strategies versus just we want to understand. Yeah.

397
00:26:23,204 --> 00:26:26,593
Yeah. Yeah, exactly. And now you are focusing a

398
00:26:26,713 --> 00:26:30,034
lot now on, I guess, less

399
00:26:30,254 --> 00:26:33,496
theoretical sort of applications and

400
00:26:33,596 --> 00:26:37,337
more, I guess, practical applications,

401
00:26:37,397 --> 00:26:40,619
especially when it comes to climate. Why

402
00:26:43,640 --> 00:26:46,921
Well, again, I think that if you just

403
00:26:46,981 --> 00:26:50,443
identify the problem and you don't work on the solutions, it's a lot.

404
00:26:51,343 --> 00:26:54,544
Obviously, it's important to identify the problem and understand the problem. You

405
00:26:54,584 --> 00:26:58,144
cannot solve it otherwise. But there

406
00:26:58,184 --> 00:27:01,405
is a lot to be said for also trying to figure it out what is the best

407
00:27:01,525 --> 00:27:05,525
way to address it. And I

408
00:27:05,565 --> 00:27:09,006
think Georgia Tech in that regard, it's a fantastic place to be because

409
00:27:09,046 --> 00:27:12,447
you have so many opportunities of collaborating with people

410
00:27:12,647 --> 00:27:16,347
that can bring also the solution side, the engineers, for

411
00:27:16,407 --> 00:27:19,928
example. And so it's kind

412
00:27:19,968 --> 00:27:23,359
of an automatic thing to do, at least for me because,

413
00:27:23,840 --> 00:27:28,283
again, I do like to work collaboratively and

414
00:27:28,823 --> 00:27:32,026
I really appreciate to be able to have that

415
00:27:32,086 --> 00:27:35,328
engagement and do new things all the time. Of

416
00:27:35,488 --> 00:27:38,691
course. You learn if you are working with someone that

417
00:27:41,273 --> 00:27:44,555
Absolutely. Can you talk about maybe one of the first projects that you worked

418
00:27:44,615 --> 00:27:48,332
on where it was more solution-focused and where that collaborative

419
00:27:48,412 --> 00:27:52,053
effort happen and how that collaborative, like how that networking

420
00:27:55,794 --> 00:27:59,114
Sure, I have several at this point. There is

421
00:27:59,355 --> 00:28:03,135
one that I find extremely interesting which

422
00:28:03,215 --> 00:28:07,936
is about sargassum in the tropical Atlantic. We

423
00:28:07,956 --> 00:28:11,717
have had since 2011 blooms of

424
00:28:11,777 --> 00:28:15,258
sargassum in a region of the tropical Atlantic

425
00:28:15,298 --> 00:28:18,539
around 10 north where we never used

426
00:28:18,579 --> 00:28:22,122
to. Right. And those blooms are growing, are

427
00:28:22,162 --> 00:28:26,506
growing over time. They're becoming bigger and bigger, essentially. And

428
00:28:26,726 --> 00:28:30,109
they are really impacting the Caribbeans and

429
00:28:30,129 --> 00:28:33,852
the Gulf of Mexico all the way to Florida because all

430
00:28:33,912 --> 00:28:37,495
this amount of the sargassum at some point gets to the beaches and

431
00:28:37,535 --> 00:28:41,714
it needs to be cleaned up or it rottens. It's

432
00:28:41,794 --> 00:28:45,176
absorbing a very large amount of carbon

433
00:28:45,196 --> 00:28:48,719
dioxide from the atmosphere to grow, but then it's releasing

434
00:28:48,819 --> 00:28:52,241
it once it gets to the beaches. And so we have to figure out why it's

435
00:28:54,563 --> 00:28:58,065
Yeah. And just to interrupt a little bit, I just wanted to give the

436
00:28:58,105 --> 00:29:01,848
audience a perspective on how much actually

437
00:29:01,948 --> 00:29:05,491
comes to the coast. I went to Mexico one

438
00:29:05,531 --> 00:29:09,173
year, and along the beach, it would

439
00:29:09,333 --> 00:29:13,108
go up to my knees. in in sargasm like i was really

440
00:29:13,168 --> 00:29:16,450
up to my knees in it and it was all along the beach to the point

441
00:29:16,490 --> 00:29:20,685
where there are now this was a resort there were garbage

442
00:29:20,705 --> 00:29:25,086
truck, or not garbage truck, sorry, dump trucks that

443
00:29:25,106 --> 00:29:28,287
were just there constantly, just being filled up with

444
00:29:28,367 --> 00:29:31,607
diggers and being filled up with sargassum, and

445
00:29:31,647 --> 00:29:34,808
then they would go and dump it somewhere, and then they would come back, and they would do that

446
00:29:35,228 --> 00:29:38,689
all day. So that tranquility that you expected on

447
00:29:38,729 --> 00:29:42,029
a beach wasn't very tranquil with trucks

448
00:29:42,089 --> 00:29:45,390
working 24 hours a day just trying to get all

449
00:29:45,430 --> 00:29:48,832
that sarcasm off. So I just wanted to kind of put that in perspective to people, like how

450
00:29:48,892 --> 00:29:52,053
much is coming along the beach? And that wasn't just Mexico. That was

451
00:29:52,093 --> 00:29:55,435
a lot of beaches in the Caribbean, as you mentioned, in

452
00:29:56,596 --> 00:30:00,237
Yeah. Florida and Caribbean, I think together, they're spending

453
00:30:00,477 --> 00:30:04,159
the order of $300 million per year now, just for cleanup purposes,

454
00:30:04,359 --> 00:30:08,061
because you cannot leave it on the beach. Otherwise, you kill the tourists. Yeah.

455
00:30:08,081 --> 00:30:11,684
Yeah. huge nuisance

456
00:30:11,784 --> 00:30:14,985
on top of being, you know, bad for the environment if

457
00:30:16,065 --> 00:30:19,927
Yeah, exactly. Even just the smell of a degrading sargassum is

458
00:30:22,908 --> 00:30:26,329
Yeah, so, you know, I'm working with colleagues in the

459
00:30:26,349 --> 00:30:30,191
School of Biology, I'm working with colleagues in chemical and

460
00:30:30,671 --> 00:30:34,893
biogeochemical engineering, and in mechanical engineering, to

461
00:30:34,953 --> 00:30:38,214
try to figure it out why we have

462
00:30:38,354 --> 00:30:41,710
this excess of sargassum now. what is promoting those

463
00:30:41,750 --> 00:30:44,811
blooms and are they going to continue in the future. It

464
00:30:45,991 --> 00:30:49,572
doesn't look that we ever had them before. Also

465
00:30:49,612 --> 00:30:52,833
from historical records, so written records, we

466
00:30:52,933 --> 00:30:56,154
don't have records of blooms this large in that

467
00:30:56,214 --> 00:31:00,115
area. But they appear in

468
00:31:00,195 --> 00:31:03,496
2011. We kind of know why they appeared, why they

469
00:31:03,516 --> 00:31:07,117
are growing. Not yet, not that clear. So

470
00:31:07,317 --> 00:31:10,666
I'm working on that. But we're also

471
00:31:10,706 --> 00:31:15,189
working on trying to figure out what to do with all this sargassum. There

472
00:31:15,209 --> 00:31:18,312
are several groups both in the US and in Europe that are

473
00:31:18,352 --> 00:31:21,714
considering essentially pulling

474
00:31:21,754 --> 00:31:25,257
it together when it's possible out at sea and sinking

475
00:31:25,317 --> 00:31:28,440
it. And we need to figure it

476
00:31:28,560 --> 00:31:33,263
out how much that costs also from an energetic perspective, and

477
00:31:33,283 --> 00:31:36,765
what could be the damage, if any, that

478
00:31:36,785 --> 00:31:40,547
we do to the ecosystem in the deep ocean if

479
00:31:40,588 --> 00:31:44,230
we dump those large amount of sargassum. And

480
00:31:44,290 --> 00:31:47,592
of course, anything that you do in the ocean, if it's

481
00:31:47,672 --> 00:31:51,934
within the 200 miles from the coastlines, also

482
00:31:51,994 --> 00:31:55,776
need a policy and the legislation and

483
00:31:55,976 --> 00:32:00,988
permits, and so it gets complicated. Yeah. The

484
00:32:01,188 --> 00:32:04,551
other solution we are thinking is to

485
00:32:04,611 --> 00:32:07,973
collect it and then transform it into

486
00:32:08,033 --> 00:32:11,535
biofuels. And that's

487
00:32:11,796 --> 00:32:16,219
the colleague in chemistry

488
00:32:16,419 --> 00:32:19,841
and chemical and biogeochemical engineering and

489
00:32:19,861 --> 00:32:24,065
the colleague in mechanical engineering that are looking into that. And

490
00:32:24,665 --> 00:32:27,886
the problem of converting sargassum into biofuel is

491
00:32:27,926 --> 00:32:32,248
that the amount of lipid

492
00:32:32,528 --> 00:32:36,069
in the sargassum is quite limited. And so you

493
00:32:36,209 --> 00:32:39,610
would need to spend a lot of energy to increase that

494
00:32:39,670 --> 00:32:43,032
concentration. So we are looking for ways of doing

495
00:32:43,092 --> 00:32:47,913
that in a natural, with

496
00:32:47,993 --> 00:32:51,615
some kind of natural system

497
00:32:51,675 --> 00:32:55,138
that can help us in that. And so

498
00:32:55,178 --> 00:32:58,879
a colleague of mine, Jeff Davis, is

499
00:32:58,939 --> 00:33:02,861
looking into using black fly larvae, which

500
00:33:02,921 --> 00:33:06,301
is a fly that lives in the tropics. And it's

501
00:33:06,462 --> 00:33:10,623
very good at eating up a lot of sargassum

502
00:33:10,683 --> 00:33:14,744
or other material. And it's

503
00:33:15,244 --> 00:33:19,258
very good at accumulating lipids. And

504
00:33:19,298 --> 00:33:22,862
therefore, then you could extract the biofuel from

505
00:33:26,365 --> 00:33:29,668
Which is crazy to think about. If you think about this larvae, there's probably about maybe

506
00:33:29,708 --> 00:33:33,371
this big to extract all those lipids and how much you have to extract

507
00:33:36,754 --> 00:33:39,817
Exactly. I think a lot of people would cringe at just the fact of

508
00:33:42,787 --> 00:33:46,708
But it's a very efficient way of

509
00:33:46,768 --> 00:33:49,949
doing it, and it's not very expensive at all,

510
00:33:50,149 --> 00:33:55,311
also from an energetic perspective. And those flies

511
00:33:55,431 --> 00:33:58,832
have no side effects to

512
00:34:03,434 --> 00:34:06,795
I don't think they bite, the black... Because the black flies up here in

513
00:34:10,042 --> 00:34:13,203
Exactly. Keep them constrained. Keep them all in one spot.

514
00:34:13,223 --> 00:34:18,224
Keep them all together. There

515
00:34:18,284 --> 00:34:21,645
is another that I read recently, an

516
00:34:21,705 --> 00:34:25,106
article of someone that in the Caribbean is using the

517
00:34:25,166 --> 00:34:28,486
leftovers from a brewery that make rum,

518
00:34:29,446 --> 00:34:33,546
essentially, increase, to

519
00:34:33,586 --> 00:34:37,188
make a mix of that plus sargassum that can be converted

520
00:34:37,749 --> 00:34:41,191
So the byproduct of making rum used to mix with

521
00:34:41,231 --> 00:34:44,393
the sargassum to create the biofuel, or

522
00:34:46,694 --> 00:34:49,857
Yeah, and another one of

523
00:34:50,097 --> 00:34:54,840
just using sargassum that has been shown to be possibly

524
00:34:54,880 --> 00:34:58,242
a good idea, this has come from Mexico and is essentially a

525
00:34:58,402 --> 00:35:01,540
one-person business. or one family or a

526
00:35:01,580 --> 00:35:04,961
family business, and they are making bricks

527
00:35:05,561 --> 00:35:09,142
out of sargassum. So they are drying the sargassum and compressing them

528
00:35:09,222 --> 00:35:12,884
and making bricks. And one

529
00:35:13,444 --> 00:35:16,785
good thing about that is that those bricks seem to be

530
00:35:19,046 --> 00:35:22,147
better. So if you make a house out of

531
00:35:22,187 --> 00:35:25,869
those bricks, it will resist

532
00:35:26,309 --> 00:35:30,189
or it will be resilient. towards

533
00:35:34,192 --> 00:35:37,735
So far you've identified two to three things that Sargassum, like

534
00:35:37,775 --> 00:35:41,418
the byproduct of using Sargassum, would actually

535
00:35:41,638 --> 00:35:44,960
help sort

536
00:35:45,000 --> 00:35:48,141
of people adapt to climate change. So, you know, we have the

537
00:35:48,201 --> 00:35:51,882
bricks, which are stronger than regular concrete cinder

538
00:35:51,902 --> 00:35:55,463
blocks that are used, I guess, in Caribbean houses

539
00:35:55,523 --> 00:35:58,704
and homes that will make them even more resistant to the

540
00:35:58,764 --> 00:36:02,125
higher winds that you would see in hurricanes, like

541
00:36:02,145 --> 00:36:06,066
in more intense storms. We also have using a biofuel, which

542
00:36:06,086 --> 00:36:09,407
would probably be better than using regular fossil fuels to

543
00:36:10,230 --> 00:36:14,232
provide energy for us, which is great. Did

544
00:36:19,134 --> 00:36:22,316
And you can sink it, yeah, because it is absorbing carbon, right? So

545
00:36:22,336 --> 00:36:26,098
the idea is to allow it to absorb carbon, but

546
00:36:26,198 --> 00:36:29,579
not allow it to release the carbon back into the atmosphere, which

547
00:36:29,840 --> 00:36:33,160
would be... Not only does it absorb carbon, but you can even make

548
00:36:33,200 --> 00:36:37,063
it better by creating a biofuel and a more

549
00:36:37,123 --> 00:36:40,425
resistant brick that could help in building houses in the Caribbean

550
00:36:40,465 --> 00:36:43,747
and this thing. So there's a lot of benefits here, not just

551
00:36:43,907 --> 00:36:47,269
one benefit, but there's a lot of solutions for this climate solution. And

552
00:36:48,029 --> 00:36:51,611
so where are they at in terms, like obviously the person in Mexico,

553
00:36:52,051 --> 00:36:55,353
small business, family owned business, is slowly starting this

554
00:36:55,654 --> 00:36:59,131
up. Is that scalable? Do

555
00:36:59,531 --> 00:37:03,553
Yeah, I don't know. Honestly, I've not looked into the

556
00:37:03,573 --> 00:37:06,815
scalability of the problem, so I cannot answer

557
00:37:07,595 --> 00:37:10,817
That's for economists and business people to worry about. You worry about more

558
00:37:14,138 --> 00:37:17,640
We are looking into the scalability of sinking it

559
00:37:17,700 --> 00:37:21,582
and the scalability of making biofuel using the

560
00:37:22,902 --> 00:37:26,164
Gotcha. Now, let's talk about the sinking of it, because I've heard a lot

561
00:37:26,424 --> 00:37:31,129
of different things when we hear about sinking

562
00:37:31,229 --> 00:37:34,470
these carbon sources. If you sink carbon sources, they

563
00:37:34,510 --> 00:37:38,171
go to the bottom. I guess the idea, and you can correct me if I'm wrong, is that it

564
00:37:39,091 --> 00:37:43,173
becomes basically like hydrocarbons again, eventually going

565
00:37:43,233 --> 00:37:46,414
into the seafloor and then kind of burying them in the seafloor. And

566
00:37:46,434 --> 00:37:49,655
they don't get released. They just stay there, just kind of like how we see oil and

567
00:37:49,695 --> 00:37:52,996
gas pockets that we get now. They're just in the

568
00:37:53,036 --> 00:37:56,337
seafloor. The problem with that,

569
00:37:56,397 --> 00:38:00,203
though, is like you mentioned before, we just don't know the

570
00:38:00,243 --> 00:38:03,666
potential, if there are, consequences of sinking that

571
00:38:03,806 --> 00:38:07,388
much into the deep sea. We just don't know the ramifications of

572
00:38:08,890 --> 00:38:12,512
Correct. The deep sea is full of bacteria and

573
00:38:12,812 --> 00:38:16,215
viruses and other little animals, and

574
00:38:16,255 --> 00:38:20,058
so the impact of having those big chunks of

575
00:38:20,979 --> 00:38:24,501
sargassum, it's not obvious.

576
00:38:25,542 --> 00:38:29,348
I would say probably is not huge if

577
00:38:29,388 --> 00:38:32,469
you can do it far enough from any kind of

578
00:38:32,529 --> 00:38:36,010
coastline. Because you can imagine that when a whale dies and

579
00:38:36,090 --> 00:38:40,332
sinks, it's not releasing less. It's

580
00:38:40,432 --> 00:38:44,174
not being a smaller perturbation than a whole patch

581
00:38:44,214 --> 00:38:47,535
of sargassum. The problem with the sargassum is that it's going to happen

582
00:38:47,555 --> 00:38:51,285
more or less in the same place every year, right? And

583
00:38:51,606 --> 00:38:55,027
it's very, very hard to put forward these kind

584
00:38:55,067 --> 00:38:58,409
of solutions without having the data to prove that you're not

585
00:38:58,649 --> 00:39:02,912
damaging the system. And unfortunately, those

586
00:39:02,992 --> 00:39:06,514
data are very expensive to collect, because

587
00:39:06,554 --> 00:39:09,735
you essentially have to send, you have to sync and you have to

588
00:39:09,795 --> 00:39:13,697
send down cameras and you have to go back, you

589
00:39:13,737 --> 00:39:16,879
know, after six months or after a year and try to figure it

590
00:39:16,999 --> 00:39:21,735
out what is happening. And so it's

591
00:39:23,936 --> 00:39:27,136
And expensive. Yes, absolutely. To do even those

592
00:39:27,196 --> 00:39:30,577
pilot studies where it becomes expensive. It's similar in

593
00:39:30,617 --> 00:39:33,998
a way to what people are worried about

594
00:39:34,018 --> 00:39:38,558
with deep sea mining. That's more of an extractive exercise

595
00:39:38,598 --> 00:39:42,119
and an extractive opportunity, whereas this one is more of an addition,

596
00:39:42,519 --> 00:39:45,980
where we're actually adding more stuff. But like you said, it could

597
00:39:46,020 --> 00:39:49,249
happen in the same place And unfortunately, we

598
00:39:49,289 --> 00:39:52,412
just don't, if it's done to scale all at once, we don't

599
00:39:52,452 --> 00:39:55,915
know the ramifications of that. If it's done in spots

600
00:39:56,135 --> 00:39:59,358
and it's done properly where it's allocated in different regions and we can

601
00:39:59,398 --> 00:40:03,461
see the breakdown happen, if the breakdown does happen down

602
00:40:04,682 --> 00:40:07,925
in the deep, then maybe it'd be a little bit better. I

603
00:40:07,965 --> 00:40:11,708
think the problem is just people just don't know, right?

604
00:40:11,748 --> 00:40:15,091
When we talk about carbon capture like that, is we just don't know

605
00:40:15,251 --> 00:40:18,527
and we see that there could be a lot of bad things that could happen, which is

606
00:40:18,587 --> 00:40:22,149
probably giving that resistance enough to try

607
00:40:25,091 --> 00:40:28,514
Yeah. It's also that, I mean, right now, in order to put those solutions

608
00:40:28,574 --> 00:40:31,896
forward, we have to be able to verify what the

609
00:40:32,577 --> 00:40:36,179
outcome will be, how much they will take, how much carbon they

610
00:40:36,199 --> 00:40:39,362
will take down, how much they will cost, because there is

611
00:40:39,422 --> 00:40:42,984
also a cost associated with going and collecting it. And

612
00:40:43,024 --> 00:40:47,260
you have to make sure that the CO2 you use by running

613
00:40:47,420 --> 00:40:51,123
your vessel that needs to go out and collect is

614
00:40:51,223 --> 00:40:55,205
not offsetting all the advantage

615
00:40:59,028 --> 00:41:02,190
I mean, you can hope to use solar panels and all

616
00:41:02,230 --> 00:41:05,532
of that, but you have to do a calculation and you have to make sure that you can do

617
00:41:05,613 --> 00:41:08,658
it that way. And so there are still a

618
00:41:08,698 --> 00:41:12,299
lot of questions that, unfortunately, we don't have answer

619
00:41:12,339 --> 00:41:16,260
to. But I can see the

620
00:41:16,320 --> 00:41:21,261
sinking, the conversion into biofuel to be absolutely potential

621
00:41:21,341 --> 00:41:25,143
good solutions to the problem. And,

622
00:41:31,625 --> 00:41:34,737
Yeah, exactly. The toolbox will have to

623
00:41:38,558 --> 00:41:42,000
How close, for both of those sort

624
00:41:42,260 --> 00:41:45,582
of solutions, how close are we to getting

625
00:41:45,662 --> 00:41:48,923
some of those answers? For the

626
00:41:48,963 --> 00:41:52,805
syncing, have there been any experiments of syncing Sargassum?

627
00:41:53,185 --> 00:41:56,527
Yes. Okay. And if I'm

628
00:41:56,607 --> 00:42:00,413
not mistaken, group

629
00:42:00,473 --> 00:42:03,657
from Great Britain has done most of that

630
00:42:03,717 --> 00:42:07,662
work, because they managed to link with

631
00:42:08,042 --> 00:42:12,007
a company that would like to do it and get credit for

632
00:42:12,087 --> 00:42:15,851
it. And so they, they

633
00:42:15,891 --> 00:42:19,475
were sinking Sargassum, I think, this

634
00:42:19,615 --> 00:42:23,212
past summer. and they will go back and

635
00:42:23,372 --> 00:42:27,575
they put cameras and they instrument the

636
00:42:27,796 --> 00:42:31,098
regions where they put it down. And I have not heard from them. I

637
00:42:33,861 --> 00:42:36,923
It's the summer, so it's still early in terms of it. Even with one years of

638
00:42:36,983 --> 00:42:40,186
data, you're still going to need multiple years of data to really find out

639
00:42:40,726 --> 00:42:44,610
the true difference, if there are any, in

640
00:42:48,697 --> 00:42:52,178
Yes, but I think that if we can show that clearly

641
00:42:52,218 --> 00:42:55,778
there is no major change of any kind, and

642
00:42:55,878 --> 00:42:59,319
it's just, you know, being chewed up

643
00:42:59,379 --> 00:43:03,279
by bacteria slowly, that would be... Yeah,

644
00:43:03,319 --> 00:43:07,320
as long as you show that there's a decomposition. Yeah, yeah. And

645
00:43:08,060 --> 00:43:11,461
for the blackfly larvae, my colleague here

646
00:43:11,861 --> 00:43:16,002
is working in the lab and doing some experiments. And

647
00:43:16,202 --> 00:43:19,941
my other colleague is advising PhD student

648
00:43:20,121 --> 00:43:23,504
that is looking at how that would scale in terms of

649
00:43:25,125 --> 00:43:28,508
cost and in terms of how many larvae

650
00:43:28,528 --> 00:43:32,531
we need and how big needs to be the implementation

651
00:43:34,512 --> 00:43:38,335
Let me ask you this. How many larvae does he have in his experiments? I'm

652
00:43:38,896 --> 00:43:42,098
Oh, right now he is in the lab. It's

653
00:43:44,550 --> 00:43:48,691
I feel like that's a lab I would not want to go and visit because there's

654
00:43:50,632 --> 00:43:54,713
No, he's looking at optimizing the

655
00:43:54,793 --> 00:43:58,495
mixture of sargassum. If you just give them sargassum,

656
00:43:58,535 --> 00:44:01,636
they don't grow all that much. So you have to add a little bit of

657
00:44:01,696 --> 00:44:05,317
something else that they really like, especially at the beginning. And

658
00:44:05,357 --> 00:44:08,879
then once they pick up and they start growing, then they will eat all the sargassum

659
00:44:08,899 --> 00:44:12,300
you give them. So they are trying to optimize that.

660
00:44:12,911 --> 00:44:16,195
and really looking at having curves and

661
00:44:16,435 --> 00:44:20,039
all the data required to then eventually move

662
00:44:20,079 --> 00:44:23,303
forward and put actual data into how

663
00:44:24,631 --> 00:44:27,813
Gotcha. So again, still fairly early stages, but the

664
00:44:27,913 --> 00:44:31,435
experiment's going on to give us those results and to continue those

665
00:44:31,495 --> 00:44:34,717
results going. That's phenomenal. That's

666
00:44:34,757 --> 00:44:38,020
really cool. Are there other projects that you've been working on,

667
00:44:38,500 --> 00:44:42,062
doesn't have to be recent or could be a little further or even recent, that you

668
00:44:44,984 --> 00:44:48,586
Yeah, we are working on several projects related to

669
00:44:48,726 --> 00:44:52,292
coral reefs. Okay. We have developed

670
00:44:52,332 --> 00:44:55,734
in my group, again, I'm a modeler. So we use

671
00:44:55,814 --> 00:44:59,376
models all the time. And we have developed a machine learning system.

672
00:44:59,456 --> 00:45:02,738
So using a little bit of artificial intelligence to

673
00:45:02,858 --> 00:45:07,261
figure it out what is the connectivity among

674
00:45:07,461 --> 00:45:10,683
reefs. So essentially, if you have a reef or an

675
00:45:10,783 --> 00:45:14,585
area in the oceans where you have a very healthy ecosystem, or

676
00:45:14,665 --> 00:45:18,207
anyway, a very important ecosystem that

677
00:45:18,567 --> 00:45:22,273
you want to observe and preserve, possibly.

678
00:45:23,753 --> 00:45:27,454
You know that because of the oceans, there are currents, it's

679
00:45:27,534 --> 00:45:31,095
probably connected to someone else or to something else,

680
00:45:31,335 --> 00:45:35,116
because it's probably exchanging genetic material to

681
00:45:35,156 --> 00:45:38,957
larvae and fries, which are the baby fish, with

682
00:45:39,197 --> 00:45:42,778
another region outside this localized area

683
00:45:42,818 --> 00:45:46,270
that you're looking at. And because

684
00:45:46,350 --> 00:45:49,712
currents are pretty powerful, those regions can be pretty large.

685
00:45:49,953 --> 00:45:53,875
So essentially I can be in Fiji

686
00:45:54,115 --> 00:45:57,458
and I may be getting larvae from a place that

687
00:45:57,558 --> 00:46:00,720
is 300 kilometers far away. And

688
00:46:00,820 --> 00:46:03,902
so I want to figure it out if that's really the

689
00:46:03,942 --> 00:46:08,045
case and how far I can go depending

690
00:46:08,165 --> 00:46:11,908
on the kind of fish or the coral species that I'm considering.

691
00:46:13,005 --> 00:46:16,626
Depending on that, I will know more or less how long a larva can survive

692
00:46:16,766 --> 00:46:20,427
in the water. Right. You

693
00:46:20,447 --> 00:46:24,368
know, be able to then attach and spawn. Yeah. And

694
00:46:24,388 --> 00:46:28,129
so we are doing that using artificial intelligence and machine learning and

695
00:46:28,189 --> 00:46:31,870
essentially using satellite data of sea surface temperature anomalies

696
00:46:31,990 --> 00:46:35,691
because they are linked to currents and building

697
00:46:35,771 --> 00:46:39,512
networks where we can see that. And we have done it in the Pacific. We

698
00:46:39,532 --> 00:46:43,198
have done it in the Atlantic. and we've done it in the Mediterranean

699
00:46:43,239 --> 00:46:46,881
Sea. So that has been really interesting

700
00:46:46,901 --> 00:46:50,404
because in the Mediterranean Sea we don't have much in terms of corals

701
00:46:50,564 --> 00:46:53,766
but we have been able to follow the invasions of the

702
00:46:53,826 --> 00:46:57,889
species that comes from the Red Sea to the Suez Canal and

703
00:46:58,390 --> 00:47:02,393
in the last 10 years or so have been really damaging

704
00:47:02,513 --> 00:47:06,663
the Mediterranean ecosystem because they We

705
00:47:06,703 --> 00:47:10,505
have essentially imported tons of lionfish,

706
00:47:10,945 --> 00:47:14,127
and lionfish, nobody can eat it, and they

707
00:47:14,167 --> 00:47:18,009
destroy everything. So

708
00:47:18,089 --> 00:47:22,592
we have been following essentially how the lionfish

709
00:47:22,652 --> 00:47:26,253
are spread, most likely through eggs, brought to

710
00:47:26,273 --> 00:47:30,347
the Suez Canal. In

711
00:47:30,427 --> 00:47:34,049
the Pacific, we have been able to look at why

712
00:47:34,129 --> 00:47:38,072
certain area in the Coral Triangle is doing

713
00:47:39,292 --> 00:47:42,794
pretty well overall. So it's sometimes it glitches

714
00:47:42,954 --> 00:47:46,476
because temperatures are going up and we had very strong El

715
00:47:46,516 --> 00:47:50,078
Niños and La Niñas and usually when those events

716
00:47:50,118 --> 00:47:53,760
happen, temperature there really change

717
00:47:53,860 --> 00:47:57,329
drastically. But nonetheless, they are recovering. and

718
00:47:57,389 --> 00:48:00,832
they continue to be quite biodiverse and relatively healthy. So

719
00:48:00,852 --> 00:48:04,755
we have checked, we figured that and usually,

720
00:48:05,135 --> 00:48:08,718
so what we found is that the system is incredibly dynamic. And

721
00:48:08,798 --> 00:48:12,501
so in the Pacific, there isn't a single place that,

722
00:48:13,062 --> 00:48:16,584
or at least there are areas where no

723
00:48:16,624 --> 00:48:19,887
matter what happens, some other area will bring new

724
00:48:19,927 --> 00:48:23,309
larvae in within a year time. And

725
00:48:23,329 --> 00:48:26,726
the usually they don't bleach at the same time.

726
00:48:26,746 --> 00:48:29,967
Right. You know, one is maybe very sensitive to La

727
00:48:30,007 --> 00:48:33,568
Niñas, the other is very sensitive to El Niños. But

728
00:48:33,608 --> 00:48:37,250
what happened is that when I have an El Niño, the one that bleaches get

729
00:48:37,730 --> 00:48:41,191
larvae from a different place, and whenever I have La Niña,

730
00:48:41,231 --> 00:48:44,552
the one that was giving the larvae may receive it from another one.

731
00:48:50,442 --> 00:48:54,545
So year to year, the variability of the connectivity among

732
00:48:54,905 --> 00:48:58,348
reefs is very different. It's very, very dynamic. And

733
00:48:58,388 --> 00:49:01,931
that has helped the system in certain areas,

734
00:49:01,991 --> 00:49:05,193
not everywhere, to really stand out

735
00:49:05,753 --> 00:49:09,576
as it's still doing well despite everything. The

736
00:49:09,616 --> 00:49:13,059
same is not true in the Atlantic. And in fact, in the Atlantic, we are not seeing

737
00:49:13,159 --> 00:49:16,481
corals recovering as much as certain areas

738
00:49:16,541 --> 00:49:19,836
of the Pacific. Now, is that because the sources are not

739
00:49:19,896 --> 00:49:23,538
changing or is it because... That dynamics is

740
00:49:23,598 --> 00:49:27,581
not there, the variability is not there. Essentially, the current system

741
00:49:27,941 --> 00:49:32,203
goes from Brazil, Belize, north.

742
00:49:32,964 --> 00:49:36,686
And so if you cut and if you kind of bleach and really damage

743
00:49:36,966 --> 00:49:40,248
any point or any big chunk in that

744
00:49:40,268 --> 00:49:44,070
trajectory, because the trajectory is pretty much always the same, you

745
00:49:44,090 --> 00:49:47,958
are going to essentially cut the supply of fresh larvae. healthy

746
00:49:47,998 --> 00:49:52,300
larvae to Florida and the Gulf of Mexico and the Caribbeans. And

747
00:49:52,360 --> 00:49:56,102
so Florida, Gulf of Mexico and the Caribbeans have been seeing strong

748
00:49:59,943 --> 00:50:03,645
It's kind of interesting because we see the output from the Amazon River

749
00:50:04,125 --> 00:50:08,387
in Brazil. I don't think we understand how

750
00:50:08,447 --> 00:50:11,808
damaging that could be and how powerful that mouth is

751
00:50:11,909 --> 00:50:15,176
in terms of that current and then going up into the

752
00:50:15,236 --> 00:50:18,278
Caribbean, into the Gulf of Mexico. Is that correct? Like a lot of

753
00:50:20,540 --> 00:50:24,162
No, it's really more that temperatures have

754
00:50:26,444 --> 00:50:30,066
And we are really bleaching systems just

755
00:50:30,086 --> 00:50:33,329
because of temperature. Just because of temperature. And other

756
00:50:33,349 --> 00:50:37,692
stressors, the Florida and the Gulf of Mexico have, you

757
00:50:37,712 --> 00:50:41,354
know, one thing to be very clear, it's not

758
00:50:41,474 --> 00:50:45,027
just that is getting warmer. It's also

759
00:50:45,087 --> 00:50:48,391
that we are dumping much more stuff in the ocean than

760
00:50:48,411 --> 00:50:51,875
we used to. And so the Pacific has

761
00:50:51,895 --> 00:50:55,899
the advantage of still being more pristine, just

762
00:50:56,099 --> 00:50:59,443
fewer people live on those islands. Some of the islands are

763
00:50:59,483 --> 00:51:06,208
completely inhabited, have no people living there. The

764
00:51:06,228 --> 00:51:09,949
stressor in the Atlantic are heat, for sure, but

765
00:51:10,009 --> 00:51:13,530
also pollution, big time. And

766
00:51:13,890 --> 00:51:17,691
overfishing and having just

767
00:51:18,632 --> 00:51:22,353
weaker ecosystems on

768
00:51:23,133 --> 00:51:26,674
That's why it's so important to have marine protected areas

769
00:51:26,974 --> 00:51:30,196
and quotas and stressors, or

770
00:51:30,236 --> 00:51:33,657
not stressors, sorry, regulations to decrease water

771
00:51:33,677 --> 00:51:37,074
pollution. all to help these animals

772
00:51:37,154 --> 00:51:40,377
adapt to the higher temperatures. So if we take away all the human stressors, or

773
00:51:40,857 --> 00:51:44,200
most of those human stressors, then perhaps the corals and

774
00:51:44,240 --> 00:51:48,084
other animals have the ability to adapt to the higher sea

775
00:51:50,466 --> 00:51:54,037
Yes, absolutely. So I have a colleague actually, just my

776
00:51:54,117 --> 00:51:58,381
office on the side, who has worked on sea

777
00:51:58,421 --> 00:52:01,944
cucumbers. And he has found that,

778
00:52:02,324 --> 00:52:05,607
for example, in Moorea, where there is a big

779
00:52:05,667 --> 00:52:09,451
effort that has been going on for more than 20 years, funded

780
00:52:09,471 --> 00:52:12,954
by the National Science Foundation to do a long-term monitoring of

781
00:52:13,014 --> 00:52:16,476
the coral reefs there. Some reefs have

782
00:52:16,596 --> 00:52:20,618
been doing much better because sea

783
00:52:20,658 --> 00:52:24,359
cucumbers have not been eradicated. Sea

784
00:52:24,379 --> 00:52:27,921
cucumbers have become a delicacy in certain Asian countries, and

785
00:52:27,961 --> 00:52:31,923
so there have been fish, and really overfish, and

786
00:52:32,403 --> 00:52:35,564
sea cucumbers, they discovered, they

787
00:52:35,584 --> 00:52:39,466
just published last year, are really the

788
00:52:39,506 --> 00:52:44,686
cleaners of the bottom of the ocean. They

789
00:52:44,786 --> 00:52:48,588
really remove any kind of virus, bacteria, stuff that you have. And

790
00:52:48,668 --> 00:52:53,931
so they help corals to thrive immensely. And

791
00:52:53,951 --> 00:52:57,493
so I postdoc here at Georgia Tech, working with my colleague Markay, was

792
00:52:58,234 --> 00:53:01,696
trying to plant corals. You can break

793
00:53:01,856 --> 00:53:05,458
coral and make little corals and plant them, essentially,

794
00:53:05,538 --> 00:53:08,780
in order to establish a population that has

795
00:53:08,820 --> 00:53:12,170
been damaged. And there were a bunch of sea cucumbers where

796
00:53:12,210 --> 00:53:15,652
he tried to do it and he removed the sea cucumbers. And for the first time,

797
00:53:16,492 --> 00:53:19,874
all his corals, little corals died. And

798
00:53:19,954 --> 00:53:24,277
so he made the connection that, you know, usually his

799
00:53:24,377 --> 00:53:27,859
efforts have been successful in the past. And so why this time

800
00:53:27,959 --> 00:53:31,220
that happened? And he remembered he has removed, he removed the

801
00:53:31,260 --> 00:53:34,522
sea cucumbers. And so they went back and they started studying it

802
00:53:34,602 --> 00:53:38,164
and found that they are essential. So that's another stressor

803
00:53:38,204 --> 00:53:41,847
that we add just for They're not particularly

804
00:53:41,927 --> 00:53:45,269
tasty. There is no reason, you know, it's more

805
00:53:46,790 --> 00:53:50,012
Yeah. As many times it is. Yeah. Yeah. It's

806
00:53:50,092 --> 00:53:54,179
very, very similar to like shark fin soup in a way. Except

807
00:53:54,299 --> 00:53:57,840
sea cucumbers are probably not as iconic as a shark, you know, when

808
00:53:57,860 --> 00:54:01,241
we think about it. Exactly. This is, you

809
00:54:01,261 --> 00:54:04,522
know, fantastic. This has all been quite interesting. You're working

810
00:54:04,582 --> 00:54:07,923
on a number of projects. Is there anything upcoming that you're

811
00:54:07,963 --> 00:54:11,164
starting to work on or you just started to work on that you're looking forward to

812
00:54:15,365 --> 00:54:19,326
Yeah, we are working on a large project across

813
00:54:19,366 --> 00:54:22,771
different universities to figured out

814
00:54:22,931 --> 00:54:26,913
how much alkalinity enhancement we could do in

815
00:54:26,953 --> 00:54:30,594
the Gulf of Mexico and through the Mississippi River Basin to

816
00:54:31,174 --> 00:54:34,476
what is called weathering. This consists in

817
00:54:34,736 --> 00:54:38,777
adding essentially

818
00:54:38,837 --> 00:54:43,619
pulverized rock to agricultural

819
00:54:43,719 --> 00:54:48,587
fields or directly in the ocean. to

820
00:54:48,887 --> 00:54:52,768
reduce the CO2 by forming carbonates.

821
00:54:55,289 --> 00:54:58,450
So the CO2 that is in the air will react with the

822
00:54:58,470 --> 00:55:01,671
dust and form carbonates and

823
00:55:01,691 --> 00:55:05,012
then those carbonates will eventually sink if

824
00:55:05,032 --> 00:55:08,793
they are in the ocean or if it's done over agricultural land

825
00:55:08,873 --> 00:55:13,095
will end up in the waterways. at

826
00:55:13,135 --> 00:55:16,696
the end if it's the Mississippi River basin in the Mississippi and

827
00:55:16,716 --> 00:55:22,318
therefore in the Gulf of Mexico. So we are doing high-resolution simulations

828
00:55:22,418 --> 00:55:26,940
or simulations down to one kilometer essentially of

829
00:55:27,140 --> 00:55:30,381
what it may happen in the Gulf of Mexico if this is

830
00:55:30,441 --> 00:55:34,023
scaled up. And as part of this project there

831
00:55:34,063 --> 00:55:38,044
are also farmers that

832
00:55:38,284 --> 00:55:41,967
are trying to see the impact of

833
00:55:43,628 --> 00:55:47,251
using fertilizers that contain a little

834
00:55:47,291 --> 00:55:50,834
bit of the dust and so really trying to see also

835
00:55:50,974 --> 00:55:54,357
at the land level what the impact could be, how fast

836
00:55:54,397 --> 00:55:57,680
they will get in the water system, in the waterways and so on. So this

837
00:55:57,760 --> 00:56:02,223
is incredibly interesting because it goes from really land

838
00:56:02,263 --> 00:56:07,585
to ocean to the region, linking

839
00:56:08,485 --> 00:56:12,869
Absolutely. Showing that watershed effect on

840
00:56:12,889 --> 00:56:16,293
the ocean and how important it is to manage not only

841
00:56:16,493 --> 00:56:19,616
water and oceans, but also land. I think we

842
00:56:19,656 --> 00:56:23,019
see it a lot and you probably see it a lot, especially where you are in Georgia Tech in

843
00:56:23,079 --> 00:56:26,550
terms of the Mississippi plume. We've known

844
00:56:26,610 --> 00:56:30,171
for a long time that that plume has a huge effect on the Gulf of Mexico and

845
00:56:30,551 --> 00:56:33,732
everything that comes down, all the fertilizers and all that that come down and

846
00:56:33,752 --> 00:56:37,294
cause that big bloom in the spring and

847
00:56:37,334 --> 00:56:40,515
then the bloom goes down into the

848
00:56:40,555 --> 00:56:43,776
bottom as the phytoplankton die and then you get

849
00:56:43,816 --> 00:56:47,578
that bacteria that uses up the oxygen to decompose that and you get basically

850
00:56:47,618 --> 00:56:51,019
hypoxic zones along the Gulf of Mexico. However, if

851
00:56:51,059 --> 00:56:54,169
you start to turn that around, and start to

852
00:56:54,209 --> 00:56:57,451
look at what you can do in terms, like you mentioned, putting in the

853
00:56:57,531 --> 00:57:01,372
rock dust onto the fields, getting into the Mississippi

854
00:57:01,392 --> 00:57:04,954
or getting into the waterways, getting into the ocean. You can reverse

855
00:57:05,514 --> 00:57:08,756
the shift from alkaline to acidic and really

856
00:57:08,796 --> 00:57:12,617
help out not only corals, but a lot of mollusks like

857
00:57:12,798 --> 00:57:16,019
oysters and mussels and clams and

858
00:57:16,607 --> 00:57:20,569
scallops that can help build their shells and snails and crustaceans

859
00:57:20,589 --> 00:57:24,312
like lobsters and shrimp and everything that use calcium, that

860
00:57:24,352 --> 00:57:27,553
need calcium in their bodies, right? So I think

861
00:57:27,593 --> 00:57:30,935
that's, this is all fantastic. I mean, this must

862
00:57:31,035 --> 00:57:34,297
make your work such like a lot better than just

863
00:57:34,818 --> 00:57:38,300
identifying the consequences that climate

864
00:57:38,320 --> 00:57:41,634
change, you know, can cause. How

865
00:57:41,674 --> 00:57:45,537
has this changed your outlook, like switching from modeling

866
00:57:45,577 --> 00:57:49,280
the effects of climate change to looking at solutions?

867
00:57:49,460 --> 00:57:53,043
Personally for you, how has that changed your

868
00:57:53,143 --> 00:57:56,445
outlook on sort of what climate change can do

869
00:57:57,746 --> 00:58:01,008
Well, it gives me hope that, you know, we are at the point of

870
00:58:01,068 --> 00:58:04,451
really thinking about how to solve the problem or at least

871
00:58:04,651 --> 00:58:08,093
how to find solutions that make sense and

872
00:58:08,133 --> 00:58:11,424
that can help. Again, it's not

873
00:58:11,464 --> 00:58:15,426
a done deal in any way and the portfolio

874
00:58:15,466 --> 00:58:18,647
of solutions that we will need is really large because the problem is

875
00:58:18,707 --> 00:58:22,229
big. But I also see, you

876
00:58:22,249 --> 00:58:25,350
know, the Gulf of Mexico has also a lot of, we do a

877
00:58:25,390 --> 00:58:28,852
lot of work with NOAA, so the National

878
00:58:28,912 --> 00:58:32,574
Atmospheric and Oceanic Administration, looking at both corals and

879
00:58:32,674 --> 00:58:36,588
fisheries and how to best manage them. And

880
00:58:37,529 --> 00:58:41,190
there is really a lot of attention in trying to

881
00:58:41,970 --> 00:58:46,911
preserve what is left and help

882
00:58:47,071 --> 00:58:51,672
with the resiliency of those systems. So it

883
00:58:56,214 --> 00:59:00,035
And I think that also looking at communities

884
00:59:00,175 --> 00:59:03,753
and fishing communities, fishermen's

885
00:59:03,773 --> 00:59:07,774
communities, they do understand. So

886
00:59:08,254 --> 00:59:11,816
it's much easier today to work with

887
00:59:11,876 --> 00:59:15,697
those communities and they have

888
00:59:15,777 --> 00:59:19,038
seen the changes. They have seen the decrease in fish, for

889
00:59:19,118 --> 00:59:22,640
example, in the population, so in the ecosystems, the

890
00:59:22,680 --> 00:59:27,702
damage, et cetera, and they want to help. And there is

891
00:59:27,742 --> 00:59:30,863
a discourse that it's much better than

892
00:59:30,963 --> 00:59:34,107
used to be. And what is

893
00:59:34,187 --> 00:59:38,254
great is that the science ivory tower

894
00:59:43,585 --> 00:59:46,867
Yeah. Yeah. That silo has come down and you're getting more

895
00:59:46,927 --> 00:59:50,629
into the community. And I think it's a benefit for not only for you as

896
00:59:50,690 --> 00:59:54,012
a researcher, but also for your students who get to interact with

897
00:59:54,032 --> 00:59:57,254
the community and be able to work on projects very

898
00:59:57,334 --> 01:00:00,476
similar to those, or maybe building on the

899
01:00:00,516 --> 01:00:03,778
projects that you're already working or even expanding those projects where we're seeing more

900
01:00:03,798 --> 01:00:07,040
and more solutions and increasing that hope. Because look, we know

901
01:00:07,280 --> 01:00:10,622
one solution is not going to solve this. It's going to take a lot. It's going to take a lot of people.

902
01:00:11,115 --> 01:00:15,076
and to be able to collaborate, which is a huge part of science, as

903
01:00:15,156 --> 01:00:18,798
well as conservation, and to be able to find these solutions that,

904
01:00:19,098 --> 01:00:22,979
you know, whether it's one or two or three or all of them that work out, then

905
01:00:25,340 --> 01:00:28,861
And I think... Tomorrow I have

906
01:00:29,001 --> 01:00:32,502
a phone call, a Zoom call with

907
01:00:32,782 --> 01:00:36,564
program managers and a student of

908
01:00:36,624 --> 01:00:39,805
mine and a colleague of mine in mechanical engineering, because we would

909
01:00:39,845 --> 01:00:43,953
like to learn how coral listen,

910
01:00:44,013 --> 01:00:48,137
how coral larvae respond to sound. Right.

911
01:00:48,377 --> 01:00:51,620
Because we think that that will really help restoring some of those

912
01:00:51,700 --> 01:00:54,804
coral reefs. And it's just unbelievable. Like, you

913
01:01:00,177 --> 01:01:03,379
And, you know, we have a problem and there are a bunch of people trying to

914
01:01:03,439 --> 01:01:07,160
solve it. And so we can also think of using sound

915
01:01:07,280 --> 01:01:10,582
or chemical cues and trying to figure it out how they...

916
01:01:13,693 --> 01:01:17,377
And what I love, it's combining that research of discovering these amazing

917
01:01:17,417 --> 01:01:21,380
things and then putting it towards a solution that can help rebuild

918
01:01:21,541 --> 01:01:24,663
these very important habitats and hopefully find ways just like we

919
01:01:24,703 --> 01:01:27,967
did, just like you did in the Southeast Pacific, like

920
01:01:28,027 --> 01:01:31,190
in near Indonesia, where the coral triangle, where there are some corals who

921
01:01:31,250 --> 01:01:34,653
are doing really well. Why are they doing really well? Because then you do the research and

922
01:01:34,673 --> 01:01:38,518
you figure that out and maybe that can be duplicated somewhere else, or we

923
01:01:38,538 --> 01:01:41,660
can find similar patterns and trends, because that's what

924
01:01:41,700 --> 01:01:45,422
science does. And I love what you're doing, Annalisa. I think it's fantastic.

925
01:01:45,462 --> 01:01:48,723
And I want to thank you so much for coming on here and sharing your

926
01:01:48,763 --> 01:01:52,025
research with us, as well as your collaborators. I think this

927
01:01:52,085 --> 01:01:55,147
is something that we need to see and hear more of. So I

928
01:01:55,207 --> 01:01:58,448
really do appreciate you coming on the podcast and sharing that. And I would love

929
01:01:58,508 --> 01:02:01,570
to extend another invitation on to discuss more of

930
01:02:01,590 --> 01:02:04,731
the projects that you've done at a later date, to be able to get updates on the

931
01:02:04,751 --> 01:02:07,954
projects that we discussed here. and learn more about some of the other projects that you

932
01:02:16,523 --> 01:02:19,725
Thank you, Annalisa, for joining me on today's episode of the How to Protect the Ocean

933
01:02:19,745 --> 01:02:23,506
podcast. It was great to be able to hear about your career, your determination, your

934
01:02:23,586 --> 01:02:26,728
motivation to prove people wrong, including your own father, which

935
01:02:26,748 --> 01:02:30,109
I think is really great, and to show how well you can do

936
01:02:30,229 --> 01:02:33,630
with that motivation and where you're at in your career is

937
01:02:33,891 --> 01:02:37,472
unbelievable. The stuff that you've accomplished and the stuff that you're helping

938
01:02:37,552 --> 01:02:40,893
to accomplish by looking for solutions on climate change.

939
01:02:40,953 --> 01:02:44,196
I just think it was really cool. talk about how we can use a

940
01:02:44,296 --> 01:02:47,599
problem, like a pesky problem like sargassum just

941
01:02:47,719 --> 01:02:50,802
accruing on the beaches and accumulating in the amount that it

942
01:02:50,862 --> 01:02:53,944
is on the beaches. As I mentioned, like I went to Mexico and there was

943
01:02:54,065 --> 01:02:57,528
knee deep in sargassum and people don't like it. Sargassum doesn't really feel good

944
01:02:57,688 --> 01:03:01,231
on the feet or on your skin. It's a little rough and

945
01:03:01,671 --> 01:03:04,874
people just don't like it. They think it's gross and nobody wants to swim on

946
01:03:04,914 --> 01:03:08,197
a beach like that. So imagine taking that sargassum and doing something

947
01:03:08,297 --> 01:03:12,023
good with it. to either sink it or make biofuels

948
01:03:12,163 --> 01:03:15,488
out of it. I just think it's absolutely amazing to look

949
01:03:15,548 --> 01:03:19,193
at the different things like to use actual black fly larvae

950
01:03:19,774 --> 01:03:23,279
to be able to accomplish what you need to make biofuels out of sargassum.

951
01:03:24,320 --> 01:03:27,721
these are the types of solutions that we need to find out. We need to do everything we

952
01:03:27,801 --> 01:03:31,102
can to get to solutions, and not only just one

953
01:03:31,142 --> 01:03:34,423
solution, we need to find many solutions. Because it's not just going to be one and done.

954
01:03:34,543 --> 01:03:38,084
We're not going to find one solution that's going to fix everything. It's not going to be fixed right

955
01:03:38,104 --> 01:03:41,385
away. It's going to take a long time to do so, but we need to do everything

956
01:03:41,425 --> 01:03:44,606
we can to do that. So I think Annalisa is on

957
01:03:44,626 --> 01:03:48,387
the right track. I think she's really showing by leading as usual, and

958
01:03:48,427 --> 01:03:51,608
that motivation to say, hey, you know what? You can't do it. She can

959
01:03:51,648 --> 01:03:54,789
do it. And then she will show you and more. So I just thought it was

960
01:03:54,849 --> 01:03:58,031
wonderful. I'm going to link to all of Annalisa's links so you can

961
01:03:58,091 --> 01:04:01,352
connect with her and you can follow her. And also if you want to

962
01:04:01,412 --> 01:04:04,533
get a hold of me and DM me on what you
