1
00:00:08,700 --> 00:00:10,233
[Narrator] There is a place...

2
00:00:10,233 --> 00:00:12,600
on this blue planet...

3
00:00:13,900 --> 00:00:15,900
unlike any other...

4
00:00:18,866 --> 00:00:20,466
...where ice retreated,

5
00:00:20,466 --> 00:00:22,866
water flowed in...

6
00:00:22,866 --> 00:00:24,433
and life exploded.

7
00:00:27,100 --> 00:00:30,533
The first people here
called it "The Dawnland"--

8
00:00:30,533 --> 00:00:32,800
the place
where the sun rose first.

9
00:00:34,433 --> 00:00:36,066
This is the story

10
00:00:36,066 --> 00:00:38,666
of how we used the treasure
of this place...

11
00:00:40,633 --> 00:00:41,933
...founded nations...

12
00:00:44,500 --> 00:00:47,600
...and devastated others.

13
00:00:47,600 --> 00:00:49,800
Today, this sea within a sea

14
00:00:49,800 --> 00:00:53,500
is warming faster
than 97% of the global ocean.

15
00:00:54,900 --> 00:00:57,700
So, what happens here
in the Gulf of Maine

16
00:00:57,700 --> 00:00:59,700
could happen everywhere,

17
00:00:59,700 --> 00:01:01,166
for jobs,

18
00:01:01,166 --> 00:01:02,466
for culture,

19
00:01:02,466 --> 00:01:04,133
for every living thing.

20
00:01:06,666 --> 00:01:08,766
But there is
a hidden strength here.

21
00:01:11,200 --> 00:01:14,533
Fishers, scientists
and the first people here

22
00:01:14,533 --> 00:01:16,300
believe answers
are in the sea...

23
00:01:17,966 --> 00:01:20,833
...a way forward...

24
00:01:20,833 --> 00:01:24,500
to strike a balance
between people and nature.

25
00:01:24,500 --> 00:01:27,133
It will happen here,

26
00:01:27,133 --> 00:01:30,133
where we face the test
that will define us all...

27
00:01:32,533 --> 00:01:33,833
...in this place,

28
00:01:33,833 --> 00:01:36,800
where the sun rises first.

29
00:01:42,000 --> 00:01:51,366
[♪♪♪♪♪]

30
00:01:52,166 --> 00:02:13,200
For thousands of years,

31
00:02:13,200 --> 00:02:16,533
the Gulf of Maine was one of
the richest places on earth.

32
00:02:17,533 --> 00:02:20,466
36,000 square miles,

33
00:02:20,466 --> 00:02:23,533
stretching from Cape Cod
to Nova Scotia in Canada.

34
00:02:25,233 --> 00:02:27,266
A special combination
of temperature,

35
00:02:27,266 --> 00:02:28,933
geography, and currents

36
00:02:28,933 --> 00:02:32,800
created an underwater Eden
teeming with life.

37
00:02:33,800 --> 00:02:35,000
For millennia,

38
00:02:35,000 --> 00:02:38,666
life in the Gulf of Maine
struck a balance and thrived.

39
00:02:40,200 --> 00:02:42,166
But in just a few centuries,

40
00:02:42,166 --> 00:02:46,000
overfishing cleared out
much of its abundance.

41
00:02:47,733 --> 00:02:49,200
This is the story

42
00:02:49,200 --> 00:02:52,133
of how we harvested
this sea of plenty,

43
00:02:52,133 --> 00:02:54,566
built empires on its cod,

44
00:02:54,566 --> 00:02:57,500
and pushed this bounty
to its limit.

45
00:02:57,500 --> 00:02:59,233
I am worried about the future

46
00:02:59,233 --> 00:03:02,366
because there's
less and less clams down here.

47
00:03:02,366 --> 00:03:03,533
[Narrator] About how

48
00:03:03,533 --> 00:03:06,100
this remarkable place
has suffered a thousand cuts

49
00:03:06,100 --> 00:03:08,100
and how the animals
and people here

50
00:03:08,100 --> 00:03:10,033
have had to adapt...

51
00:03:10,033 --> 00:03:11,166
or move on.

52
00:03:11,166 --> 00:03:12,966
[Elizabeth Craig]
These birds live a long time

53
00:03:12,966 --> 00:03:14,566
and a lot has changed here,

54
00:03:14,566 --> 00:03:15,933
so each individual bird

55
00:03:15,933 --> 00:03:18,566
is experiencing that change
in their lifetime.

56
00:03:18,566 --> 00:03:21,433
[Narrator] Now the Gulf of Maine
faces its greatest challenge.

57
00:03:23,233 --> 00:03:26,266
As it warms,
some species disappear

58
00:03:26,266 --> 00:03:27,900
as others explode.

59
00:03:27,900 --> 00:03:29,900
[Brian Altvater] I never knew
what a green crab was

60
00:03:29,900 --> 00:03:31,600
until just a few years ago.

61
00:03:31,600 --> 00:03:34,800
It's something
I never experienced growing up.

62
00:03:34,800 --> 00:03:37,300
[Narrator]
How will the gulf adapt

63
00:03:37,300 --> 00:03:39,866
and survive its deepest cut yet?

64
00:03:39,866 --> 00:03:43,633
[♪♪♪♪♪]

65
00:03:47,366 --> 00:03:50,600
[♪♪♪♪♪]

66
00:03:50,600 --> 00:03:51,933
In spring and summer,

67
00:03:51,933 --> 00:03:54,100
many of the things
that live in the Gulf of Maine

68
00:03:54,100 --> 00:03:55,800
spawn,

69
00:03:55,800 --> 00:03:59,033
and all those tiny offspring
fill the sea...

70
00:03:59,033 --> 00:04:03,333
[♪♪♪♪♪]

71
00:04:04,500 --> 00:04:06,700
...and then the eating begins.

72
00:04:08,100 --> 00:04:10,166
Tiny gets eaten by small...

73
00:04:10,166 --> 00:04:12,233
small by medium...

74
00:04:12,233 --> 00:04:15,166
medium by large,

75
00:04:15,166 --> 00:04:17,700
and a lot of it
gets eaten by us.

76
00:04:18,700 --> 00:04:21,766
Much of this eating
starts with tiny critters

77
00:04:21,766 --> 00:04:23,333
called "copepods".

78
00:04:24,400 --> 00:04:28,333
About 30 nautical miles
off of Midcoast Maine,

79
00:04:28,333 --> 00:04:30,233
a team of scientists
is on the hunt

80
00:04:30,233 --> 00:04:32,633
for some of the tiniest
creatures in the gulf.

81
00:04:32,633 --> 00:04:34,633
Looks nice!
It's kind of warm out here!

82
00:04:34,633 --> 00:04:36,333
[exhales happily]

83
00:04:36,333 --> 00:04:38,500
[laughs]

84
00:04:38,500 --> 00:04:40,033
Day in the life!

85
00:04:40,033 --> 00:04:43,033
[Narrator] David Fields is
a zooplankton ecologist.

86
00:04:43,033 --> 00:04:45,233
-You ready?
-Ready?

87
00:04:45,233 --> 00:04:46,366
He's joined

88
00:04:46,366 --> 00:04:48,566
by research associate
Maura Niemisto.

89
00:04:48,566 --> 00:04:50,000
[Fields] So shallow net first?

90
00:04:50,000 --> 00:04:52,100
[Niemisto]
Shallow net first, please.

91
00:04:52,100 --> 00:04:53,966
[Narrator] They're here
to check on the engine

92
00:04:53,966 --> 00:04:56,700
that drives this ecosystem--

93
00:04:56,700 --> 00:04:59,700
a copepod
called "calanus finmarchicus".

94
00:05:01,166 --> 00:05:04,233
Copepods are tiny crustaceans.

95
00:05:04,233 --> 00:05:06,733
About five of them
could fit in a grain of rice.

96
00:05:06,733 --> 00:05:08,833
[Fields]
We're going to drop this in.

97
00:05:08,833 --> 00:05:10,233
We're looking to find out

98
00:05:10,233 --> 00:05:12,466
the abundance
and the identity

99
00:05:12,466 --> 00:05:13,633
of all the copepods

100
00:05:13,633 --> 00:05:15,833
that are down in
the water column,

101
00:05:15,833 --> 00:05:17,366
from the bottom
to the surface.

102
00:05:17,366 --> 00:05:19,366
I'm just going
to drop it.

103
00:05:19,366 --> 00:05:20,933
[Niemisto] Yeah.

104
00:05:22,366 --> 00:05:23,733
Surface, goin' down.

105
00:05:24,566 --> 00:05:26,566
[Niemisto]
We're searching for zooplankton,

106
00:05:26,566 --> 00:05:28,366
so, small animals,

107
00:05:28,366 --> 00:05:29,700
about a millimeter in size,

108
00:05:29,700 --> 00:05:31,633
that are the base
of the food chain.

109
00:05:31,633 --> 00:05:34,500
When we count and identify
the animals we find,

110
00:05:34,500 --> 00:05:35,566
we'll be able to say

111
00:05:35,566 --> 00:05:37,233
how dense those animals are

112
00:05:37,233 --> 00:05:39,200
and look at how they've
changed over time and space.

113
00:05:40,200 --> 00:05:41,566
[Fields] There it is.

114
00:05:41,566 --> 00:05:43,966
[Niemisto] Nice.

115
00:05:43,966 --> 00:05:47,500
[Narrator] The first sample
does not disappoint.

116
00:05:47,500 --> 00:05:48,600
Dense...

117
00:05:48,600 --> 00:05:50,000
full of calanus.

118
00:05:52,400 --> 00:05:54,400
If I was a right whale,
this is where I'd be.

119
00:05:54,400 --> 00:05:57,100
It's packed-filled with calanus

120
00:05:57,100 --> 00:05:59,200
and it really is
just liquid sunshine.

121
00:05:59,200 --> 00:06:00,633
[Narrator] Calanus are

122
00:06:00,633 --> 00:06:03,866
some of the fattiest copepods
in the world.

123
00:06:03,866 --> 00:06:05,100
[Fields] These are

124
00:06:05,100 --> 00:06:06,766
the primary food source
for the right whales,

125
00:06:06,766 --> 00:06:09,266
but they also,
in their younger stages,

126
00:06:09,266 --> 00:06:10,600
tend to be the food source

127
00:06:10,600 --> 00:06:11,500
for cod,

128
00:06:11,500 --> 00:06:12,800
for the shrimp,

129
00:06:12,800 --> 00:06:14,966
for much of the fisheries
that are out there,

130
00:06:14,966 --> 00:06:17,000
including the lobsters.

131
00:06:17,000 --> 00:06:18,966
[Narrator] Calanus may be tiny,

132
00:06:18,966 --> 00:06:20,433
but they number
in the trillions.

133
00:06:22,300 --> 00:06:24,266
[Fields] The reason
why a 40-ton animal

134
00:06:24,266 --> 00:06:27,500
can live off of an animal
that's two millimeters

135
00:06:27,500 --> 00:06:29,166
is because they're energy-rich.

136
00:06:29,166 --> 00:06:31,000
They store a lot of fat.

137
00:06:31,000 --> 00:06:33,633
And by the time
winter rolls around,

138
00:06:33,633 --> 00:06:35,333
these animals
go down to the bottom,

139
00:06:35,333 --> 00:06:37,833
much like what you're seeing
at the bottom here.

140
00:06:37,833 --> 00:06:39,633
And so you can imagine

141
00:06:39,633 --> 00:06:40,900
a butter layer

142
00:06:40,900 --> 00:06:42,300
from here to Norway

143
00:06:42,300 --> 00:06:46,133
of three meters thick
of high-density fat animals,

144
00:06:46,133 --> 00:06:47,400
and these whales

145
00:06:47,400 --> 00:06:50,366
just coming down
and scooping up that fat layer.

146
00:06:50,366 --> 00:06:51,533
And to survive,

147
00:06:51,533 --> 00:06:52,500
they need to eat about

148
00:06:52,500 --> 00:06:56,000
2000 to 3000 pounds
of calanus a day.

149
00:06:56,000 --> 00:06:57,466
[Narrator]
So having huge numbers

150
00:06:57,466 --> 00:06:59,600
of calanus in the gulf
is critical.

151
00:07:02,833 --> 00:07:04,066
[Niemisto] Understanding

152
00:07:04,066 --> 00:07:06,733
the smallest scale organisms
and systems and ecosystems

153
00:07:06,733 --> 00:07:07,900
really helps us

154
00:07:07,900 --> 00:07:09,833
start to understand
how the world works

155
00:07:09,833 --> 00:07:11,033
in a way
that we can't really see

156
00:07:11,033 --> 00:07:13,100
when we zoom out
to larger-scale things.

157
00:07:14,666 --> 00:07:16,900
[Narrator]
It's not just about quantity,

158
00:07:16,900 --> 00:07:19,066
it's where these critters
are hanging out,

159
00:07:19,066 --> 00:07:21,033
because so many in the gulf
eat them...

160
00:07:22,666 --> 00:07:24,000
...and those animals migrate

161
00:07:24,000 --> 00:07:25,900
to wherever
dinner's being served.

162
00:07:25,900 --> 00:07:29,766
So here we are
at 30 nautical miles offshore.

163
00:07:29,766 --> 00:07:32,533
All right.
You guys already hooked up?

164
00:07:32,533 --> 00:07:33,666
-Yep.
-Already hooked up.

165
00:07:33,666 --> 00:07:35,200
[Narrator] Once a month,

166
00:07:35,200 --> 00:07:36,200
David and his team

167
00:07:36,200 --> 00:07:38,600
get a snapshot
of what's on the menu.

168
00:07:38,600 --> 00:07:40,166
[Fields] The real beauty

169
00:07:40,166 --> 00:07:41,833
of doing
these kind of measurements

170
00:07:41,833 --> 00:07:43,266
is in the repetition

171
00:07:43,266 --> 00:07:45,333
of coming out
over long time periods,

172
00:07:45,333 --> 00:07:46,900
to try to separate out

173
00:07:46,900 --> 00:07:50,400
the natural variability
that happens year to year,

174
00:07:50,400 --> 00:07:52,666
from the superimposed change

175
00:07:52,666 --> 00:07:55,000
that's happening
due to climatic conditions,

176
00:07:55,000 --> 00:07:56,033
or changing climates.

177
00:07:57,033 --> 00:07:58,000
Coming up!

178
00:07:58,000 --> 00:08:00,566
[Narrator]
The sample is a surprise.

179
00:08:00,566 --> 00:08:03,133
Usually in spring and summer,

180
00:08:03,133 --> 00:08:05,400
calanus live in
the top layer of the gulf,

181
00:08:05,400 --> 00:08:06,600
where they're fed on

182
00:08:06,600 --> 00:08:08,700
by everything
from herring to whales.

183
00:08:09,833 --> 00:08:11,100
By late summer,

184
00:08:11,100 --> 00:08:12,300
this kind of copepod

185
00:08:12,300 --> 00:08:14,966
typically drops
to cold waters at depth

186
00:08:14,966 --> 00:08:16,666
and goes dormant,

187
00:08:16,666 --> 00:08:18,966
literally chilling out.

188
00:08:18,966 --> 00:08:21,066
[Fields] Here we are now
in November,

189
00:08:21,066 --> 00:08:23,433
and we're sampling
in the upper 10 meters.

190
00:08:23,433 --> 00:08:27,000
We're still finding
an abundant number of calanus.

191
00:08:27,000 --> 00:08:29,266
And it's unclear to me

192
00:08:29,266 --> 00:08:30,400
whether the animals

193
00:08:30,400 --> 00:08:31,733
that we're seeing
up in the upper water column

194
00:08:31,733 --> 00:08:33,933
are because the water is warmer,

195
00:08:33,933 --> 00:08:36,566
or if that's just
kind of their natural cycle.

196
00:08:37,700 --> 00:08:38,833
[Narrator] Whatever the reason,

197
00:08:38,833 --> 00:08:41,400
hungry whales will go
wherever they need to eat.

198
00:08:43,266 --> 00:08:45,066
[Fields]
As the climate gets warmer,

199
00:08:45,066 --> 00:08:46,966
the whales will search
for those places

200
00:08:46,966 --> 00:08:48,300
and they'll find them.

201
00:08:48,300 --> 00:08:50,700
I mean, there's no doubt
about that.

202
00:08:50,700 --> 00:08:53,566
But as they move into
these new hunting grounds,

203
00:08:53,566 --> 00:08:55,733
those happen to be
in shipping lanes.

204
00:08:55,733 --> 00:08:56,800
They happen to be

205
00:08:56,800 --> 00:09:00,066
in fishing grounds
that are unregulated.

206
00:09:00,066 --> 00:09:01,366
[Narrator]
So this tiny creature

207
00:09:01,366 --> 00:09:03,800
is having
an outsized impact here.

208
00:09:03,800 --> 00:09:06,466
These are
the charismatic megafauna.

209
00:09:06,466 --> 00:09:07,666
They really are.

210
00:09:07,666 --> 00:09:08,866
As a group,

211
00:09:08,866 --> 00:09:12,533
they are such an important level
in that food chain

212
00:09:12,533 --> 00:09:14,800
that disruptions
that happen at these levels

213
00:09:14,800 --> 00:09:16,000
are transmitted

214
00:09:16,000 --> 00:09:18,533
all the way up the food chain
and down the food chain.

215
00:09:18,533 --> 00:09:20,800
[Narrator] As if on cue,

216
00:09:20,800 --> 00:09:22,633
the top of the food chain
arrives...

217
00:09:23,833 --> 00:09:25,500
[screaming]

218
00:09:26,700 --> 00:09:27,833
It's like a flipper!

219
00:09:28,866 --> 00:09:30,866
That's fantastic!

220
00:09:30,866 --> 00:09:32,100
[Narrator]
A northern right whale

221
00:09:32,100 --> 00:09:34,433
makes a rare appearance,

222
00:09:34,433 --> 00:09:37,166
trailed by pilot whales
and white-sided dolphins.

223
00:09:37,166 --> 00:09:38,366
[Niemisto] I think this is

224
00:09:38,366 --> 00:09:40,633
the second time
I've ever seen them out here.

225
00:09:40,633 --> 00:09:42,300
[Fields] Yeah, wow.

226
00:09:42,300 --> 00:09:44,633
It's really just extraordinary.

227
00:09:44,633 --> 00:09:46,633
Oh, that is so beautiful!

228
00:09:46,633 --> 00:09:49,800
Unbelievable!

229
00:09:49,800 --> 00:09:51,533
What a treat.

230
00:09:51,533 --> 00:09:54,466
We've seen one or two whales
out here in the past.

231
00:09:54,466 --> 00:09:55,966
And we've certainly seen

232
00:09:55,966 --> 00:09:57,500
the white-sided dolphins
out here

233
00:09:57,500 --> 00:09:59,300
and the mola molas.

234
00:09:59,300 --> 00:10:02,366
But it's really
a fantastic sight.

235
00:10:05,800 --> 00:10:07,400
[Narrator]
As the Gulf of Maine warms,

236
00:10:07,400 --> 00:10:09,500
these sightings
are becoming less frequent

237
00:10:09,500 --> 00:10:12,966
because whales are moving
to where the water is colder

238
00:10:12,966 --> 00:10:14,366
and where the food is.

239
00:10:16,133 --> 00:10:18,600
Here in the gulf,
it's all about the eating,

240
00:10:18,600 --> 00:10:20,066
and, for thousands of years,

241
00:10:20,066 --> 00:10:22,466
one eater topped them all,

242
00:10:22,466 --> 00:10:26,900
a ferocious predator
that ate anything on offer,

243
00:10:26,900 --> 00:10:29,800
but one which you might be
more familiar with

244
00:10:29,800 --> 00:10:32,833
as the fish in fish and chips...

245
00:10:32,833 --> 00:10:34,866
the codfish.

246
00:10:37,866 --> 00:10:39,300
The First People
in the Gulf of Maine

247
00:10:39,300 --> 00:10:41,533
fished cod
for thousands of years,

248
00:10:41,533 --> 00:10:43,900
taking only
what they could eat and trade.

249
00:10:46,066 --> 00:10:47,533
By the 11th century,

250
00:10:47,533 --> 00:10:48,833
Vikings were following codfish

251
00:10:48,833 --> 00:10:50,200
from Scandinavia

252
00:10:50,200 --> 00:10:52,533
to the North Atlantic Coast
of North America.

253
00:10:55,366 --> 00:10:57,100
In the early 1600s,

254
00:10:57,100 --> 00:10:58,966
the first permanent colonists
showed up.

255
00:11:00,166 --> 00:11:01,466
[Mark Kurlansky]
There were hundreds,

256
00:11:01,466 --> 00:11:03,600
maybe thousands of Europeans,

257
00:11:03,600 --> 00:11:07,066
fishing in these waters
in the Gulf of Maine,

258
00:11:07,066 --> 00:11:10,600
and coming to the shore
to dry and cure fish.

259
00:11:10,600 --> 00:11:12,266
[Narrator]
Using racks to dry fish

260
00:11:12,266 --> 00:11:14,733
was already
a centuries-old technology

261
00:11:14,733 --> 00:11:17,433
and was used
well past the Colonial Period.

262
00:11:18,833 --> 00:11:21,900
The attraction wasn't just
the sheer number of fish,

263
00:11:21,900 --> 00:11:25,166
it was the biology
of this particular fish.

264
00:11:25,166 --> 00:11:27,100
[Kurlansky] It has no fat

265
00:11:27,100 --> 00:11:29,300
and it is ideal for curing,

266
00:11:29,300 --> 00:11:30,900
for salting or drying,

267
00:11:30,900 --> 00:11:32,366
and before refrigeration,

268
00:11:32,366 --> 00:11:33,266
that was the only way

269
00:11:33,266 --> 00:11:35,433
you could have
a commercial fish.

270
00:11:35,433 --> 00:11:38,866
Live codfish
is about 18% protein,

271
00:11:38,866 --> 00:11:40,033
so once you dry it,

272
00:11:40,033 --> 00:11:42,366
the percentage of protein
is huge.

273
00:11:42,366 --> 00:11:44,533
This is like a protein wafer.

274
00:11:46,266 --> 00:11:49,100
[Narrator] Cured cod
could be stockpiled for months

275
00:11:49,100 --> 00:11:50,700
and travel well.

276
00:11:51,733 --> 00:11:54,000
Soon, this protein wafer

277
00:11:54,000 --> 00:11:55,766
became a staple
in colonial diets

278
00:11:55,766 --> 00:11:57,633
up and down
the Atlantic Seaboard.

279
00:12:01,133 --> 00:12:02,700
By 1700,

280
00:12:02,700 --> 00:12:04,166
a triangle of trade

281
00:12:04,166 --> 00:12:06,966
between the New World,
West Africa and Europe

282
00:12:06,966 --> 00:12:08,200
had exploded,

283
00:12:08,200 --> 00:12:10,566
pumping wealth
into places like Boston.

284
00:12:11,766 --> 00:12:13,633
Slavery was one of the ways

285
00:12:13,633 --> 00:12:15,666
in which you could make
a lot of money,

286
00:12:15,666 --> 00:12:18,533
so codfish merchants
wanted to get in on it,

287
00:12:18,533 --> 00:12:21,600
and they would sell salt cod
to West Africa--

288
00:12:21,600 --> 00:12:24,366
which is why
it's a staple in Nigeria today--

289
00:12:24,366 --> 00:12:27,266
and from that,
buy slaves for the Caribbean.

290
00:12:28,500 --> 00:12:30,733
[Narrator] The trade in cod
cannot be disentangled

291
00:12:30,733 --> 00:12:32,766
from the trade in humans.

292
00:12:32,766 --> 00:12:35,166
That combination
of wealth and misery

293
00:12:35,166 --> 00:12:37,466
was a part of
New England's foundation.

294
00:12:38,633 --> 00:12:41,300
Cod made up more than
half of all its trade

295
00:12:41,300 --> 00:12:43,666
and became known
as "British Gold".

296
00:12:44,733 --> 00:12:47,333
And the families
who made fortunes from cod

297
00:12:47,333 --> 00:12:49,966
became known
as the "Codfish Aristocracy".

298
00:12:49,966 --> 00:12:52,200
[Kurlansky] By the 18th century,

299
00:12:52,200 --> 00:12:53,933
cod had lifted New England

300
00:12:53,933 --> 00:12:56,300
from a handful
of starving settlers

301
00:12:56,300 --> 00:12:58,933
to an international economy.

302
00:12:58,933 --> 00:13:00,066
[Narrator] Who soon realized

303
00:13:00,066 --> 00:13:02,733
that maybe they didn't need
Great Britain anymore.

304
00:13:03,933 --> 00:13:05,133
We learned in school

305
00:13:05,133 --> 00:13:07,600
how the American Revolution
was about freedom.

306
00:13:09,000 --> 00:13:10,533
It was about capitalism...

307
00:13:11,533 --> 00:13:13,900
...and about the right
to make money

308
00:13:13,900 --> 00:13:16,400
that was at the root
of New England thinking

309
00:13:16,400 --> 00:13:19,033
and at the root
of the American Revolution.

310
00:13:19,033 --> 00:13:20,533
And a lot of that

311
00:13:20,533 --> 00:13:24,566
came from the ability
to trade cod.

312
00:13:24,566 --> 00:13:26,166
[Narrator]
Trading in commodities,

313
00:13:26,166 --> 00:13:27,866
like timber and molasses,

314
00:13:27,866 --> 00:13:30,033
drove New England's economy.

315
00:13:30,033 --> 00:13:31,700
And critical to the list--

316
00:13:31,700 --> 00:13:33,833
slaves for cod.

317
00:13:33,833 --> 00:13:37,666
This deadly, lucrative trade
fueled the demand for fish,

318
00:13:37,666 --> 00:13:41,033
and innovative Yankees
were happy to oblige.

319
00:13:41,033 --> 00:13:43,700
[Kurlansky]
Every innovation was applied,

320
00:13:43,700 --> 00:13:45,466
where possible,

321
00:13:45,466 --> 00:13:47,000
to catching more fish.

322
00:13:47,000 --> 00:13:48,533
That's what fishermen
wanted to do

323
00:13:48,533 --> 00:13:50,166
was catch more fish.

324
00:13:52,166 --> 00:13:53,533
[Narrator] In the 17th century,

325
00:13:53,533 --> 00:13:58,033
an in-shore fisherman
could catch 200 fish in a day.

326
00:13:58,033 --> 00:13:59,866
About 300 years later,

327
00:13:59,866 --> 00:14:02,533
technology
had changed everything

328
00:14:02,533 --> 00:14:04,033
and a diesel-powered trawler

329
00:14:04,033 --> 00:14:06,933
could pull out that fisherman's
entire year's catch

330
00:14:06,933 --> 00:14:08,566
in a single day.

331
00:14:09,633 --> 00:14:11,466
Then the world took another leap

332
00:14:11,466 --> 00:14:13,766
with the invention
of flash-freezing food.

333
00:14:15,100 --> 00:14:17,600
[Kurlansky] Freezing opened
a different chapter

334
00:14:17,600 --> 00:14:20,333
in the international trade
of food

335
00:14:20,333 --> 00:14:24,033
because now you could ship food
everywhere.

336
00:14:24,033 --> 00:14:25,633
[Narrator]
Frozen fish sticks and filets

337
00:14:25,633 --> 00:14:29,100
became staples
in homes around the world,

338
00:14:29,100 --> 00:14:30,933
and by the end
of the 20th century,

339
00:14:30,933 --> 00:14:32,133
cod in the Gulf of Maine

340
00:14:32,133 --> 00:14:35,566
were fished
to 1% of historic levels.

341
00:14:37,000 --> 00:14:39,266
The gulf became
a different ecosystem.

342
00:14:40,800 --> 00:14:42,433
With one of their main predators

343
00:14:42,433 --> 00:14:45,200
largely gone
in a now warmer gulf,

344
00:14:45,200 --> 00:14:49,966
lobster populations increased
by 500% in just 30 years,

345
00:14:49,966 --> 00:14:51,766
resulting in a fishery

346
00:14:51,766 --> 00:14:54,966
that is worth more
than a billion dollars a year.

347
00:14:56,300 --> 00:14:57,400
Luckily for the lobster,

348
00:14:57,400 --> 00:14:59,900
they're harder to catch
than cod...

349
00:15:00,800 --> 00:15:03,000
...and they have
some remarkable traits,

350
00:15:03,000 --> 00:15:06,366
including living upwards
of 100 years

351
00:15:06,366 --> 00:15:10,000
and producing some 100,000 eggs.

352
00:15:12,266 --> 00:15:14,600
This is prime lobster habitat.

353
00:15:14,600 --> 00:15:17,200
These rock piles
create nooks and crannies

354
00:15:17,200 --> 00:15:19,366
for lobsters of every size
to hide.

355
00:15:22,966 --> 00:15:24,366
Protected from predators,

356
00:15:24,366 --> 00:15:25,766
this is where females let loose

357
00:15:25,766 --> 00:15:27,833
their ultimate
survival strategy...

358
00:15:29,200 --> 00:15:31,366
...thousands of eggs.

359
00:15:31,366 --> 00:15:34,500
Lobsters rely on the odds
of hatching a ton

360
00:15:34,500 --> 00:15:36,300
and hoping a couple make it...

361
00:15:38,033 --> 00:15:41,000
...but first,
mother has to build a shelter.

362
00:15:42,033 --> 00:15:43,133
She gets to work,

363
00:15:43,133 --> 00:15:44,866
using all ten of her legs...

364
00:15:47,333 --> 00:15:50,166
...including
those famous front claws.

365
00:15:52,566 --> 00:15:54,500
Her burrow is like a fort.

366
00:15:54,500 --> 00:15:57,533
It'll protect her
from currents and predators.

367
00:15:57,533 --> 00:16:01,766
Down here,
it's not meet the neighbors...

368
00:16:01,766 --> 00:16:04,033
it's eat the neighbors.

369
00:16:04,033 --> 00:16:05,233
Amazingly,

370
00:16:05,233 --> 00:16:07,966
she's already carried these eggs
around inside her body

371
00:16:07,966 --> 00:16:09,866
for 9 to 12 months.

372
00:16:11,200 --> 00:16:12,366
Once fertilized,

373
00:16:12,366 --> 00:16:13,933
the eggs are carried
on the outside

374
00:16:13,933 --> 00:16:16,000
for another 9 to 12 months,

375
00:16:16,000 --> 00:16:18,500
glued to
the mother's swimmerets--

376
00:16:18,500 --> 00:16:20,733
appendages
typically used for swimming.

377
00:16:22,100 --> 00:16:24,833
A deeper burrow
allows her to stand,

378
00:16:24,833 --> 00:16:25,966
stretch out,

379
00:16:25,966 --> 00:16:27,833
and fan her eggs.

380
00:16:27,833 --> 00:16:31,600
This increases the water flow
between the tightly-packed eggs,

381
00:16:31,600 --> 00:16:34,400
flushing them
with cold gulf water,

382
00:16:34,400 --> 00:16:36,000
rich in oxygen.

383
00:16:36,000 --> 00:16:39,233
After caring for them
for up to a year like this,

384
00:16:39,233 --> 00:16:40,900
they're fully formed

385
00:16:40,900 --> 00:16:42,966
and ready
to survive on their own.

386
00:16:45,566 --> 00:16:47,366
Stretched to her full length,

387
00:16:47,366 --> 00:16:49,933
she vigorously flaps
her swimmerets,

388
00:16:49,933 --> 00:16:52,433
shaking her babies
out of their sacs.

389
00:16:53,533 --> 00:16:55,633
Her final act as a mother...

390
00:16:56,866 --> 00:16:59,400
...releasing them
into the big ocean.

391
00:17:01,300 --> 00:17:02,766
Every year,

392
00:17:02,766 --> 00:17:04,633
hundreds of millions
of larval lobsters

393
00:17:04,633 --> 00:17:06,600
are born
into the Gulf of Maine.

394
00:17:06,600 --> 00:17:10,466
Very few will reach the same age
as their mother.

395
00:17:10,466 --> 00:17:13,300
Most won't even last
three months.

396
00:17:14,600 --> 00:17:15,866
Defenseless,

397
00:17:15,866 --> 00:17:17,233
they become food

398
00:17:17,233 --> 00:17:18,833
before they can get enough food.

399
00:17:21,000 --> 00:17:22,600
Some that do make it that long

400
00:17:22,600 --> 00:17:25,933
may help this team
predict the future of lobsters

401
00:17:25,933 --> 00:17:27,400
and their fishery.

402
00:17:28,466 --> 00:17:31,466
[Curt Brown] We want to know
where lobsters are settling.

403
00:17:31,466 --> 00:17:33,166
Are they settling further east,

404
00:17:33,166 --> 00:17:35,500
further west in shallow water,

405
00:17:35,500 --> 00:17:37,000
in deeper water?

406
00:17:37,000 --> 00:17:38,066
And the data
that we're collecting

407
00:17:38,066 --> 00:17:39,666
gives us
all of that information.

408
00:17:41,500 --> 00:17:43,733
We're gonna be hauling up
some heavy stuff today,

409
00:17:43,733 --> 00:17:46,500
so just have eyes on your feet

410
00:17:46,500 --> 00:17:47,633
and where the rope is

411
00:17:47,633 --> 00:17:49,066
at all times.

412
00:17:49,066 --> 00:17:50,033
-Sound good?
-Rock and roll.

413
00:17:50,033 --> 00:17:51,266
Off we go.

414
00:17:54,933 --> 00:17:57,100
[Narrator] Curt Brown
is a marine biologist

415
00:17:57,100 --> 00:17:58,566
and a commercial lobsterman.

416
00:17:58,566 --> 00:18:01,400
He's part of
a 35-year-long project

417
00:18:01,400 --> 00:18:04,033
called the "American Lobster
Settlement Index",

418
00:18:04,033 --> 00:18:06,700
which does exactly
what it sounds like--

419
00:18:06,700 --> 00:18:08,866
it tracks where lobsters settle,

420
00:18:08,866 --> 00:18:10,900
grow, and, eventually, mature

421
00:18:10,900 --> 00:18:13,333
into what can be caught
in the fishery.

422
00:18:13,333 --> 00:18:15,700
It's spearheaded by Rick Wahle.

423
00:18:15,700 --> 00:18:18,000
[Rick Wahle]
I started into this game

424
00:18:18,000 --> 00:18:19,533
back in 1985.

425
00:18:19,533 --> 00:18:22,000
There was
very little understanding

426
00:18:22,000 --> 00:18:23,800
of where their nursery
grounds were,

427
00:18:23,800 --> 00:18:25,733
where they
first settle.

428
00:18:25,733 --> 00:18:27,633
[Narrator] By counting
the lobsters that settle,

429
00:18:27,633 --> 00:18:28,766
the thought was

430
00:18:28,766 --> 00:18:30,000
that they could predict

431
00:18:30,000 --> 00:18:31,900
how big populations
would eventually be.

432
00:18:31,900 --> 00:18:33,833
[Wahle] The sort of Holy Grail

433
00:18:33,833 --> 00:18:36,200
was to have
an early-warning system,

434
00:18:36,200 --> 00:18:38,633
a forecasting tool
that we could use

435
00:18:38,633 --> 00:18:43,233
to follow a cohort
of newly-settled lobsters

436
00:18:43,233 --> 00:18:45,633
right into
the commercial harvest

437
00:18:45,633 --> 00:18:47,366
seven or eight years later.

438
00:18:47,366 --> 00:18:49,066
[Narrator]
The lobster fishery

439
00:18:49,066 --> 00:18:52,166
once spanned
North Carolina to Canada.

440
00:18:52,166 --> 00:18:53,400
Warming temperatures

441
00:18:53,400 --> 00:18:57,166
have all but destroyed
this fishery south of Cape Cod.

442
00:18:57,166 --> 00:18:59,500
Warmer waters have been linked
to shell disease

443
00:18:59,500 --> 00:19:01,466
and lower egg production.

444
00:19:03,566 --> 00:19:06,133
So taking the annual census
of baby lobsters

445
00:19:06,133 --> 00:19:08,100
has never been more important.

446
00:19:08,100 --> 00:19:10,733
[Wahle] Lobsters don't live
in a vacuum,

447
00:19:10,733 --> 00:19:12,066
and we're seeing that,

448
00:19:12,066 --> 00:19:14,766
right from the time
they settle to the sea bed,

449
00:19:14,766 --> 00:19:17,700
they're dealing with
all sorts of fishes,

450
00:19:17,700 --> 00:19:19,966
crabs, other invertebrates.

451
00:19:19,966 --> 00:19:22,833
Some of them are food
for other lobsters,

452
00:19:22,833 --> 00:19:24,633
and when they're really tiny,

453
00:19:24,633 --> 00:19:25,900
they're really vulnerable,

454
00:19:25,900 --> 00:19:28,800
so they have to find
a good hiding place

455
00:19:28,800 --> 00:19:30,300
as soon as they settle,

456
00:19:30,300 --> 00:19:33,400
and stay put until they outgrow
those predators.

457
00:19:33,400 --> 00:19:35,533
[Narrator]
The bid to build a crystal ball

458
00:19:35,533 --> 00:19:38,300
starts with this contraption--

459
00:19:38,300 --> 00:19:41,633
a modified lobster trap
baited with...

460
00:19:41,633 --> 00:19:42,566
rocks.

461
00:19:42,566 --> 00:19:43,766
[Andrew Goode] In order for us

462
00:19:43,766 --> 00:19:45,600
to get a sense
of what's down there,

463
00:19:45,600 --> 00:19:46,566
how much is down there,

464
00:19:46,566 --> 00:19:47,866
and their distribution,

465
00:19:47,866 --> 00:19:49,833
we put these collectors
down here,

466
00:19:49,833 --> 00:19:51,366
with their preferred habitat,

467
00:19:51,366 --> 00:19:52,366
bring them up,

468
00:19:52,366 --> 00:19:55,066
and then we're able
to peel this back

469
00:19:55,066 --> 00:19:57,200
and reveal the money within.

470
00:19:58,600 --> 00:20:01,133
[Narrator] Lobsters this size
make for good data,

471
00:20:01,133 --> 00:20:02,966
but aren't what the team
is looking for.

472
00:20:02,966 --> 00:20:05,933
They actually want
something smaller...

473
00:20:05,933 --> 00:20:06,933
much smaller.

474
00:20:09,366 --> 00:20:10,800
The lobsters
they're really after

475
00:20:10,800 --> 00:20:12,533
are only a few months old...

476
00:20:13,800 --> 00:20:16,200
...but surviving even that long
in the Gulf of Maine

477
00:20:16,200 --> 00:20:18,100
is a major feat.

478
00:20:19,066 --> 00:20:22,066
This larval lobster
is just hours old--

479
00:20:22,066 --> 00:20:23,800
about the size
of a grain of rice.

480
00:20:25,800 --> 00:20:28,633
No real claws yet,
with few to no defenses,

481
00:20:28,633 --> 00:20:30,533
it is naturally buoyant,

482
00:20:30,533 --> 00:20:32,866
and rises
to the top layer of the sea,

483
00:20:32,866 --> 00:20:34,700
joining other plankton,

484
00:20:34,700 --> 00:20:36,966
plants and animals
that drift with the wind,

485
00:20:36,966 --> 00:20:39,433
currents, and water.

486
00:20:39,433 --> 00:20:43,700
This planktonic chowder
is soup for the soul for many.

487
00:20:43,700 --> 00:20:46,766
Fish eat on the go,

488
00:20:46,766 --> 00:20:48,766
whales skim and filter,

489
00:20:48,766 --> 00:20:50,466
some birds bob...

490
00:20:50,466 --> 00:20:53,566
while others float and bob,

491
00:20:53,566 --> 00:20:55,066
but they all eat.

492
00:20:55,066 --> 00:20:58,033
No wonder why more than
99% of these guys

493
00:20:58,033 --> 00:20:59,300
don't make it out alive.

494
00:20:59,300 --> 00:21:03,800
So, this guy just settled
as a larva earlier this summer,

495
00:21:03,800 --> 00:21:06,000
so he is just a few months old,

496
00:21:06,000 --> 00:21:08,833
but it's the counts
of these guys

497
00:21:08,833 --> 00:21:09,966
that gives us

498
00:21:09,966 --> 00:21:13,200
the forecasting tool
for trends in the fisheries.

499
00:21:13,200 --> 00:21:14,400
[Narrator]
They pick this group to count

500
00:21:14,400 --> 00:21:15,833
because, given their size,

501
00:21:15,833 --> 00:21:17,966
these lobsters
were born this year.

502
00:21:17,966 --> 00:21:19,700
It's the one time in their lives

503
00:21:19,700 --> 00:21:21,866
when they can be aged
with accuracy.

504
00:21:21,866 --> 00:21:24,700
[Whale] So the numbers
on these young of year lobsters

505
00:21:24,700 --> 00:21:25,700
is really important.

506
00:21:25,700 --> 00:21:28,933
This is the 2023 year class.

507
00:21:30,666 --> 00:21:31,900
[Brown] Every year,

508
00:21:31,900 --> 00:21:33,366
Maine's coastal economy

509
00:21:33,366 --> 00:21:35,166
is driven by
the lobster fishery,

510
00:21:35,166 --> 00:21:39,000
so when we see baby lobsters
like this

511
00:21:39,000 --> 00:21:41,333
settling into our collectors,

512
00:21:41,333 --> 00:21:42,600
it's a very good sign for us.

513
00:21:42,600 --> 00:21:44,966
This is the future
of our fishery right here.

514
00:21:44,966 --> 00:21:47,033
Five to eight years from now,

515
00:21:47,033 --> 00:21:48,833
this is what we'll be catching,

516
00:21:48,833 --> 00:21:51,666
so when we know what's happening
year in and year out

517
00:21:51,666 --> 00:21:54,266
with these tiny little
one-month-old lobsters,

518
00:21:54,266 --> 00:21:55,500
it helps me make decisions

519
00:21:55,500 --> 00:21:58,500
about my business going forward
with this boat,

520
00:21:58,500 --> 00:21:59,366
with my traps,

521
00:21:59,366 --> 00:22:00,600
with my family,

522
00:22:00,600 --> 00:22:02,133
with the community.

523
00:22:02,133 --> 00:22:03,200
Without that data,

524
00:22:03,200 --> 00:22:05,033
you're kind of
making decisions blind,

525
00:22:05,033 --> 00:22:07,966
and that's really the importance
of this type of data right here.

526
00:22:09,066 --> 00:22:10,333
[Narrator] A lot of people
in the Gulf of Maine

527
00:22:10,333 --> 00:22:12,600
depend on lobsters
and this data.

528
00:22:12,600 --> 00:22:13,600
And it's not just

529
00:22:13,600 --> 00:22:15,566
the fishermen
and their families--

530
00:22:15,566 --> 00:22:16,766
it's all the boat builders,

531
00:22:16,766 --> 00:22:18,233
the trap makers, the docks,

532
00:22:18,233 --> 00:22:20,700
the bait, fuel,
and rope suppliers,

533
00:22:20,700 --> 00:22:22,233
the distributors,

534
00:22:22,233 --> 00:22:24,000
the restaurants,

535
00:22:24,000 --> 00:22:27,700
all the families
supported by this one species.

536
00:22:27,700 --> 00:22:31,100
That's quite a lot
riding on these lobster tails.

537
00:22:31,100 --> 00:22:32,766
But recently,

538
00:22:32,766 --> 00:22:36,166
warming water is making
their futures less predictable.

539
00:22:36,166 --> 00:22:37,366
[Goode] The Gulf of Maine

540
00:22:37,366 --> 00:22:40,600
is one of the fastest-warming
large marine ecosystems

541
00:22:40,600 --> 00:22:42,600
on the entire planet,

542
00:22:42,600 --> 00:22:47,433
and the trajectory of the
fishery is in question

543
00:22:47,433 --> 00:22:49,533
because as
the Gulf of Maine warms,

544
00:22:49,533 --> 00:22:50,766
near-shore habitats

545
00:22:50,766 --> 00:22:53,433
may become too warm
for settlement.

546
00:22:55,700 --> 00:22:57,166
[Narrator]
Shallow in-shore habitats

547
00:22:57,166 --> 00:23:00,900
are generally better nurseries
for baby lobsters,

548
00:23:00,900 --> 00:23:02,033
but expecting mothers

549
00:23:02,033 --> 00:23:04,066
are now going further offshore

550
00:23:04,066 --> 00:23:06,100
to hatch in cooler,
deeper waters.

551
00:23:06,100 --> 00:23:09,100
There's this phenomenon
called "climate velocity",

552
00:23:09,100 --> 00:23:10,533
where marine species

553
00:23:10,533 --> 00:23:13,600
will track
their optimal habitats--

554
00:23:13,600 --> 00:23:15,300
in this case, temperature.

555
00:23:15,300 --> 00:23:16,433
As the water warms,

556
00:23:16,433 --> 00:23:19,733
more southern species
will migrate northwards.

557
00:23:19,733 --> 00:23:22,766
[Wahle] The center of gravity
of lobsters

558
00:23:22,766 --> 00:23:25,266
is shifting northward,

559
00:23:25,266 --> 00:23:27,000
but not uniformly.

560
00:23:27,000 --> 00:23:30,566
[Narrator] So while
many lobsters are moving north,

561
00:23:30,566 --> 00:23:32,533
there is a curious twist
in this story.

562
00:23:32,533 --> 00:23:36,933
[Brown] What's very interesting
is here in Southern Maine,

563
00:23:36,933 --> 00:23:40,600
at depth below 40, 50, 60 feet,

564
00:23:40,600 --> 00:23:44,166
the water is actually colder
for most of the year

565
00:23:44,166 --> 00:23:45,300
here in Southern Maine

566
00:23:45,300 --> 00:23:47,233
than it is in Eastern Maine.

567
00:23:47,233 --> 00:23:49,966
[Narrator] Some lobsters
are moving further out to sea

568
00:23:49,966 --> 00:23:51,633
and down deeper.

569
00:23:51,633 --> 00:23:52,566
In Eastern Maine,

570
00:23:52,566 --> 00:23:53,900
you have
a more constant temperature

571
00:23:53,900 --> 00:23:55,033
top to bottom,

572
00:23:55,033 --> 00:23:57,800
but from May
till about this time of year,

573
00:23:57,800 --> 00:23:59,066
until storms really mix

574
00:23:59,066 --> 00:24:01,300
that warmer surface water
here down,

575
00:24:01,300 --> 00:24:03,866
bottom temperatures
in Southern or Western Maine

576
00:24:03,866 --> 00:24:05,066
are actually colder.

577
00:24:05,066 --> 00:24:07,500
Down at the bottom,
we're in the sweet spot.

578
00:24:07,500 --> 00:24:09,900
[Narrator]
As data comes in every year,

579
00:24:09,900 --> 00:24:11,133
the goal is to see

580
00:24:11,133 --> 00:24:12,533
how changes in the gulf

581
00:24:12,533 --> 00:24:15,033
are affecting the way
lobsters behave

582
00:24:15,033 --> 00:24:16,666
and to remove uncertainty

583
00:24:16,666 --> 00:24:17,866
for the fishery

584
00:24:17,866 --> 00:24:20,033
and the people who depend on it.

585
00:24:20,033 --> 00:24:24,866
[♪♪♪♪♪]

586
00:24:24,866 --> 00:24:28,400
While the lobster fishery
is still relatively healthy,

587
00:24:28,400 --> 00:24:30,533
families who have worked
other fisheries

588
00:24:30,533 --> 00:24:32,633
are seeing concerning changes...

589
00:24:33,766 --> 00:24:36,233
...families like the Coxes.

590
00:24:38,500 --> 00:24:39,866
As the tide rolls out...

591
00:24:39,866 --> 00:24:41,000
[Johnny Cox]
I don't roll them up.

592
00:24:41,000 --> 00:24:42,766
[Narrator]
...Johnny Cox heads to work.

593
00:24:42,766 --> 00:24:45,200
[Johnny Cox] Maybe I should
have washed them out.

594
00:24:45,200 --> 00:24:46,466
I think I'm ready.

595
00:24:46,466 --> 00:24:47,633
[laughs]

596
00:24:47,633 --> 00:24:50,333
[Narrator] Johnny's a clammer
in Jonesboro, Maine.

597
00:24:50,333 --> 00:24:51,533
He and his son, Andrew,

598
00:24:51,533 --> 00:24:54,000
spend every day they can
in these waters.

599
00:24:56,666 --> 00:24:57,966
[Andrew Cox]
Do you want to get in

600
00:24:57,966 --> 00:24:59,800
and I'll push you out?

601
00:24:59,800 --> 00:25:01,233
[Johnny Cox] No, I can get it.

602
00:25:01,233 --> 00:25:02,800
[Andrew Cox] All right.

603
00:25:04,733 --> 00:25:06,933
[Johnny Cox] All right.
Pray, pray, pray it starts.

604
00:25:06,933 --> 00:25:10,233
[starter chugging,
purring to life]

605
00:25:12,966 --> 00:25:14,333
[Andrew Cox]
Just give it to her.

606
00:25:16,066 --> 00:25:17,566
There we go.
Need for speed.

607
00:25:17,566 --> 00:25:19,800
[Narrator] Andrew started
in the family business

608
00:25:19,800 --> 00:25:21,766
before he was in kindergarten.

609
00:25:21,766 --> 00:25:24,300
I would say,
probably five, four,

610
00:25:24,300 --> 00:25:26,066
following him around.

611
00:25:26,066 --> 00:25:27,433
He used to leave me clams.

612
00:25:27,433 --> 00:25:28,933
I would be between his legs,

613
00:25:28,933 --> 00:25:30,466
and he would leave me
a clam or two,

614
00:25:30,466 --> 00:25:31,766
and I would put it
in my little roller,

615
00:25:31,766 --> 00:25:33,533
and my roller was, like, tiny.

616
00:25:33,533 --> 00:25:35,733
Then all the mud fights
and all that.

617
00:25:35,733 --> 00:25:37,466
Good times.

618
00:25:37,466 --> 00:25:38,566
Good memories.

619
00:25:40,200 --> 00:25:41,466
[Narrator] It's low tide

620
00:25:41,466 --> 00:25:44,400
and they're heading to a mudflat
that may hold some promise.

621
00:25:47,900 --> 00:25:49,233
[Johnny Cox] Clam holes!

622
00:25:49,233 --> 00:25:50,900
Oh, just right here.

623
00:25:50,900 --> 00:25:52,433
Put the anchor out.

624
00:25:53,433 --> 00:25:55,133
[Narrator] About the size
of a thumbprint,

625
00:25:55,133 --> 00:25:56,366
a clam hole is formed

626
00:25:56,366 --> 00:25:59,100
when a clam sticks its neck out
to breathe and eat.

627
00:25:59,100 --> 00:26:01,766
Johnny's an expert
at finding them--

628
00:26:01,766 --> 00:26:03,866
he's been a clammer
for most of his life.

629
00:26:05,600 --> 00:26:07,900
[Johnny Cox]
50 some-odd years, or more.

630
00:26:07,900 --> 00:26:09,366
Too long!

631
00:26:09,366 --> 00:26:10,533
[laughs]

632
00:26:10,533 --> 00:26:11,866
Time to go to work.

633
00:26:13,466 --> 00:26:15,166
The kids
that I went to school with,

634
00:26:15,166 --> 00:26:16,866
they didn't have this advantage.

635
00:26:16,866 --> 00:26:20,033
Their job was working for A&P,

636
00:26:20,033 --> 00:26:21,500
or pumping gas,

637
00:26:21,500 --> 00:26:23,833
for a dollar and a quarter
an hour,

638
00:26:23,833 --> 00:26:24,833
and here I had just--

639
00:26:24,833 --> 00:26:26,966
in three hours,
made 50 bucks.

640
00:26:26,966 --> 00:26:30,133
And back then,
$50 was big money.

641
00:26:30,133 --> 00:26:32,533
[Narrator] Today,
the soft-shell clam fishery

642
00:26:32,533 --> 00:26:35,166
is one of the most lucrative
in Maine,

643
00:26:35,166 --> 00:26:37,100
just behind lobsters
and baby eels.

644
00:26:37,100 --> 00:26:38,533
[Andrew Cox] Oh, there's one.

645
00:26:39,766 --> 00:26:40,733
[Narrator]
Whether pulling by hand,

646
00:26:40,733 --> 00:26:42,333
or digging with a rake,

647
00:26:42,333 --> 00:26:45,966
Johnny and Andrew
can make up to $2000 a day.

648
00:26:45,966 --> 00:26:48,400
[Andrew Cox]
Jonesboro has installed

649
00:26:48,400 --> 00:26:52,033
a 250-pound limit per tide.

650
00:26:52,033 --> 00:26:54,100
Usually, I try to aim
for 200 pounds,

651
00:26:54,100 --> 00:26:56,533
but the price
is always up and down,

652
00:26:56,533 --> 00:27:00,366
so, right now,
it's two bucks per pound.

653
00:27:00,366 --> 00:27:02,866
During the summers,
it can peak up to $4.00.

654
00:27:02,866 --> 00:27:04,600
You can do two tides a day.

655
00:27:04,600 --> 00:27:05,700
You do the math.

656
00:27:05,700 --> 00:27:07,066
It adds up!

657
00:27:07,066 --> 00:27:08,166
[Johnny Cox] I mean,

658
00:27:08,166 --> 00:27:09,433
if you want
to come down here and push,

659
00:27:09,433 --> 00:27:11,600
then you can come home
with a pretty good paycheck.

660
00:27:11,600 --> 00:27:14,000
[Narrator]
As good as business is,

661
00:27:14,000 --> 00:27:17,000
these mudflats,
once full of eelgrass and algae,

662
00:27:17,000 --> 00:27:19,233
aren't nearly as productive
as they used to be.

663
00:27:19,233 --> 00:27:22,233
[Johnny Cox] In the early '70s,
there was clams everywhere.

664
00:27:22,233 --> 00:27:25,100
I mean, from here on in,

665
00:27:25,100 --> 00:27:27,600
back in the late '70s,

666
00:27:27,600 --> 00:27:29,100
up to the early '80s,

667
00:27:29,100 --> 00:27:30,400
it would be all green.

668
00:27:30,400 --> 00:27:32,033
I mean, it ain't there now.

669
00:27:32,033 --> 00:27:33,233
And I've questioned that--

670
00:27:33,233 --> 00:27:34,400
what's changed?

671
00:27:34,400 --> 00:27:35,400
Green crabs.

672
00:27:38,300 --> 00:27:40,066
[Narrator] Green crabs
are an invasive species

673
00:27:40,066 --> 00:27:42,066
found along
the Gulf of Maine's coast.

674
00:27:44,200 --> 00:27:46,833
As they burrow for homes
and look for food,

675
00:27:46,833 --> 00:27:49,233
they cut up the roots
of surrounding vegetation,

676
00:27:49,233 --> 00:27:52,433
destroying vital habitat
for many other species...

677
00:27:55,366 --> 00:27:57,600
...and they've landed on
these shores in hordes.

678
00:27:58,933 --> 00:28:00,000
[Johnny Cox] I mean,

679
00:28:00,000 --> 00:28:01,600
we're not talking
three or four green crabs.

680
00:28:01,600 --> 00:28:03,400
We're talking thousands.

681
00:28:03,400 --> 00:28:06,166
So, in order for them
to survive,

682
00:28:06,166 --> 00:28:07,166
they're eating something.

683
00:28:08,433 --> 00:28:10,966
[Narrator]
And clams are an easy target.

684
00:28:10,966 --> 00:28:13,166
[Andrew Cox] That right there--
it's neck.

685
00:28:13,166 --> 00:28:15,300
That can reach
all the way up to my wrist.

686
00:28:15,300 --> 00:28:17,100
And that's where
some good meat is.

687
00:28:17,100 --> 00:28:18,333
And that's their lifeline.

688
00:28:18,333 --> 00:28:20,900
If that gets...

689
00:28:20,900 --> 00:28:22,833
well, there goes their lifeline,

690
00:28:22,833 --> 00:28:23,900
they can't eat,

691
00:28:23,900 --> 00:28:25,566
they can't reproduce,

692
00:28:25,566 --> 00:28:27,066
and they die in the mud.

693
00:28:27,066 --> 00:28:28,633
I'm not saying any names.

694
00:28:28,633 --> 00:28:30,733
Green crabs, maybe, you know,

695
00:28:30,733 --> 00:28:33,800
they come across and snip-snip.

696
00:28:33,800 --> 00:28:34,766
That's a free snack for them.

697
00:28:36,333 --> 00:28:38,166
So, yeah, I am kind of worried
about the future

698
00:28:38,166 --> 00:28:41,366
because the resource
is actually declining.

699
00:28:42,833 --> 00:28:44,533
[Narrator] Andrew is right
to be concerned.

700
00:28:44,533 --> 00:28:46,266
Like locusts,

701
00:28:46,266 --> 00:28:49,066
green crabs have descended
on this coastline,

702
00:28:49,066 --> 00:28:50,900
destroying everything
in their path.

703
00:28:52,666 --> 00:28:54,366
For decades,
Maine's frigid winters

704
00:28:54,366 --> 00:28:57,433
kept invasive species
like green crabs at bay...

705
00:28:58,800 --> 00:28:59,966
...but in recent years,

706
00:28:59,966 --> 00:29:02,700
rising ocean temperatures
have kicked the door open,

707
00:29:02,700 --> 00:29:05,233
and their numbers
have taken off.

708
00:29:07,300 --> 00:29:08,566
Picture a sci-fi movie

709
00:29:08,566 --> 00:29:12,166
in which aliens replicate
by the hundreds.

710
00:29:12,166 --> 00:29:13,766
Multiply that by a hundred,

711
00:29:13,766 --> 00:29:15,300
and you're getting an idea

712
00:29:15,300 --> 00:29:17,900
of what's taking over
the Gulf of Maine--

713
00:29:17,900 --> 00:29:19,966
green crabs.

714
00:29:21,233 --> 00:29:22,466
On the surface,

715
00:29:22,466 --> 00:29:25,333
they don't seem too different
from other crabs.

716
00:29:25,333 --> 00:29:26,366
Eight walking legs

717
00:29:26,366 --> 00:29:28,466
help them scamper
across the sea floor.

718
00:29:29,400 --> 00:29:32,566
Large claws serve as
both sword and fork.

719
00:29:33,900 --> 00:29:36,666
Antennae help them navigate
and process their world,

720
00:29:36,666 --> 00:29:39,033
mainly answering
three questions--

721
00:29:39,033 --> 00:29:40,366
Am I safe?

722
00:29:40,366 --> 00:29:42,866
Are you a good
reproductive partner?

723
00:29:42,866 --> 00:29:44,566
And can I eat you?

724
00:29:46,533 --> 00:29:48,133
One thing that sets
green crabs apart

725
00:29:48,133 --> 00:29:49,633
is how aggressive they are.

726
00:29:49,633 --> 00:29:53,033
They will crush and eat
anything in their path--

727
00:29:53,033 --> 00:29:56,000
from worms
to barnacles to snails.

728
00:29:57,433 --> 00:29:59,900
But what they really like
to feast on?

729
00:29:59,900 --> 00:30:01,233
Clams.

730
00:30:02,233 --> 00:30:03,533
To protect itself,

731
00:30:03,533 --> 00:30:06,566
this clam has burrowed
deep into the sand.

732
00:30:06,566 --> 00:30:09,800
It inhales water
through its neck siphon

733
00:30:09,800 --> 00:30:11,666
to breathe and to eat.

734
00:30:12,866 --> 00:30:14,200
So, in essence,

735
00:30:14,200 --> 00:30:16,833
this clam needs to stick
its neck out to survive...

736
00:30:17,866 --> 00:30:20,566
...and this green crab
knows how to go for the jugular.

737
00:30:22,233 --> 00:30:24,900
Sensing danger,
the clam ducks back under.

738
00:30:26,466 --> 00:30:29,700
But crabs have
a remarkable feature--

739
00:30:29,700 --> 00:30:32,066
little hairs across
their bodies and legs

740
00:30:32,066 --> 00:30:33,833
allow them to sense their prey.

741
00:30:35,600 --> 00:30:38,566
And ten legs
are no match for a young clam.

742
00:30:41,066 --> 00:30:45,566
A single crab can eat up to
40 half-inch clams in a day.

743
00:30:47,000 --> 00:30:48,133
Left unchecked,

744
00:30:48,133 --> 00:30:49,566
green crabs could obliterate

745
00:30:49,566 --> 00:30:51,533
the clamming industry
as we know it...

746
00:30:54,633 --> 00:30:58,566
...but an innovative experiment
hopes to stop them.

747
00:31:01,466 --> 00:31:03,066
Brian Altvater Senior

748
00:31:03,066 --> 00:31:05,433
is a member
of the Passamaquoddy Tribe

749
00:31:05,433 --> 00:31:07,700
and is committed to healing
the environment

750
00:31:07,700 --> 00:31:09,066
that's brought so much to him,

751
00:31:09,066 --> 00:31:10,433
his family,

752
00:31:10,433 --> 00:31:11,900
and his ancestors.

753
00:31:12,800 --> 00:31:14,966
Approximately 14,000 years,

754
00:31:14,966 --> 00:31:16,966
we've been in this vicinity,

755
00:31:16,966 --> 00:31:18,033
and a lot of people,

756
00:31:18,033 --> 00:31:19,733
like, a lot of the fishermen,

757
00:31:19,733 --> 00:31:20,733
they go out there,

758
00:31:20,733 --> 00:31:22,133
like myself,

759
00:31:22,133 --> 00:31:23,400
whether it's clams,

760
00:31:23,400 --> 00:31:24,600
or fish,

761
00:31:24,600 --> 00:31:25,900
what have you,

762
00:31:25,900 --> 00:31:27,533
it's all for sustenance.

763
00:31:27,533 --> 00:31:31,300
Everyone I knew growing up
ate clams and fish.

764
00:31:31,300 --> 00:31:34,033
You know, so...

765
00:31:34,033 --> 00:31:36,033
yeah, clams are very important.

766
00:31:36,033 --> 00:31:37,566
And...

767
00:31:37,566 --> 00:31:38,733
like, you know,

768
00:31:38,733 --> 00:31:42,066
if you went up North
to visit some of the Micmacs,

769
00:31:42,066 --> 00:31:43,933
or some of the Maliseet,

770
00:31:43,933 --> 00:31:46,900
I mean, the first thing they say
is bring up some clams,

771
00:31:46,900 --> 00:31:48,500
bring up some scallops,
you know,

772
00:31:48,500 --> 00:31:49,466
and stuff like that,

773
00:31:49,466 --> 00:31:50,900
'cause they love that stuff,
you know?

774
00:31:50,900 --> 00:31:52,366
And so we say, yeah,

775
00:31:52,366 --> 00:31:54,533
give us a few potatoes
and we'll have a deal.

776
00:31:56,266 --> 00:31:58,200
[Narrator]
These flats in Sipayik, Maine

777
00:31:58,200 --> 00:32:01,533
have always provided
for Brian and his community...

778
00:32:01,533 --> 00:32:03,333
until recently.

779
00:32:03,333 --> 00:32:05,766
[Altvater] I used to talk
to a lot of the elders,

780
00:32:05,766 --> 00:32:07,033
and they used to tell me

781
00:32:07,033 --> 00:32:09,666
about the abundance
of fish in the area,

782
00:32:09,666 --> 00:32:11,433
and shellfish,

783
00:32:11,433 --> 00:32:12,900
and that's all changed.

784
00:32:12,900 --> 00:32:15,166
I mean, like, today,
we have the green crab.

785
00:32:15,166 --> 00:32:17,966
It's something
I never experienced growing up.

786
00:32:17,966 --> 00:32:20,033
I never knew
what a green crab was

787
00:32:20,033 --> 00:32:21,900
until just a few years ago.

788
00:32:21,900 --> 00:32:23,600
They have a voracious appetite,

789
00:32:23,600 --> 00:32:26,033
and the environment
isn't used to having them,

790
00:32:26,033 --> 00:32:28,166
so a lot
of the indigenous species,

791
00:32:28,166 --> 00:32:31,633
you know, don't have
a mechanism to cope with them.

792
00:32:31,633 --> 00:32:32,833
[Narrator] Searching for ways

793
00:32:32,833 --> 00:32:34,766
to counter
the green crab invasion

794
00:32:34,766 --> 00:32:37,833
led to the idea of growing clams
inside these boxes.

795
00:32:37,833 --> 00:32:39,400
[Altvater] You know,
it's just like any other garden,

796
00:32:39,400 --> 00:32:42,433
except it's clams
down the mud flats.

797
00:32:42,433 --> 00:32:44,633
[Narrator] It's a collaboration
with Brian Beal,

798
00:32:44,633 --> 00:32:48,100
a professor of Marine Ecology
at the University of Maine.

799
00:32:48,100 --> 00:32:50,666
[Brian Beal]
This experiment is all designed

800
00:32:50,666 --> 00:32:51,933
to take a look

801
00:32:51,933 --> 00:32:54,866
at the effects of green crabs
on soft-shell clams.

802
00:32:54,866 --> 00:32:56,200
So, the one-millimeter crabs

803
00:32:56,200 --> 00:33:00,366
are eating clams that are a
half a millimeter or smaller,

804
00:33:00,366 --> 00:33:04,100
and there's billions
of tick-size green crabs

805
00:33:04,100 --> 00:33:07,500
that are eating
trillions of soft-shell clams.

806
00:33:07,500 --> 00:33:08,533
[Narrator] Every spring,

807
00:33:08,533 --> 00:33:10,866
trillions of baby clams
and green crabs

808
00:33:10,866 --> 00:33:13,433
are floating
in the Gulf of Maine,

809
00:33:13,433 --> 00:33:14,666
and, once big enough,

810
00:33:14,666 --> 00:33:17,066
drop down
and settle on the mudflats.

811
00:33:17,066 --> 00:33:20,566
The problem is,
the crabs have a size advantage.

812
00:33:22,033 --> 00:33:24,100
So, the basic idea
of this nursery

813
00:33:24,100 --> 00:33:26,366
is to plant thousands
of baby clams

814
00:33:26,366 --> 00:33:28,733
in protective boxes.

815
00:33:28,733 --> 00:33:31,833
The tight mesh lids
keep them safe from green crabs

816
00:33:31,833 --> 00:33:34,666
and give them
a few months' head start.

817
00:33:34,666 --> 00:33:36,700
Once a clam
gets to a certain size,

818
00:33:36,700 --> 00:33:39,866
it's far less vulnerable
to being eaten by a green crab.

819
00:33:39,866 --> 00:33:42,166
Timing is everything.

820
00:33:42,166 --> 00:33:43,566
There's always a race

821
00:33:43,566 --> 00:33:47,100
between when clams settle
versus when green crabs settle.

822
00:33:47,100 --> 00:33:49,366
Green crabs are settling
just about a month,

823
00:33:49,366 --> 00:33:50,600
typically, in most places,

824
00:33:50,600 --> 00:33:52,433
after the clams settle.

825
00:33:52,433 --> 00:33:55,766
So, this is what we're calling
an "intertidal clam nursery".

826
00:33:57,000 --> 00:33:58,833
What are we doing, Shawnee?
We all set?

827
00:33:58,833 --> 00:34:00,166
[Shawnee] Yeah.

828
00:34:00,166 --> 00:34:02,300
[Narrator]
With nursery boxes in tow,

829
00:34:02,300 --> 00:34:04,933
the team follows
the receding tide into the mud.

830
00:34:07,566 --> 00:34:10,366
So what's the trick
to walking out here, Dada?

831
00:34:10,366 --> 00:34:13,733
Like your cross-country ski
to push your foot forward.

832
00:34:13,733 --> 00:34:15,300
[Narrator]
They now have to set out

833
00:34:15,300 --> 00:34:17,633
and secure 112 boxes,

834
00:34:17,633 --> 00:34:20,800
filled with nearly
37,000 baby clams,

835
00:34:20,800 --> 00:34:23,800
and hope a cold winter
keeps crab numbers down.

836
00:34:23,800 --> 00:34:26,066
[Brian Beal] There's only
one thing in this state

837
00:34:26,066 --> 00:34:28,633
that regulates
green crab populations

838
00:34:28,633 --> 00:34:32,566
and that's
the temperature of the water.

839
00:34:32,566 --> 00:34:34,433
When water temperatures
are cold

840
00:34:34,433 --> 00:34:36,333
and we have lots of ice
in the wintertime,

841
00:34:36,333 --> 00:34:37,766
you can't find a green crab,

842
00:34:37,766 --> 00:34:39,000
and that's
when there's more clams

843
00:34:39,000 --> 00:34:40,933
than you know what to do with.

844
00:34:40,933 --> 00:34:42,400
When water temperatures increase

845
00:34:42,400 --> 00:34:44,033
to the point
that they are at now,

846
00:34:44,033 --> 00:34:45,100
it's hard to find a clam,

847
00:34:45,100 --> 00:34:47,766
but you can find
many green crabs.

848
00:34:47,766 --> 00:34:50,500
We're just in a place,
due to climate change,

849
00:34:50,500 --> 00:34:53,466
where the clamming industry
is in jeopardy.

850
00:34:53,466 --> 00:34:55,166
If we don't do anything else,

851
00:34:55,166 --> 00:34:56,133
what's going to happen

852
00:34:56,133 --> 00:34:57,733
is that green crab populations

853
00:34:57,733 --> 00:35:00,433
are going to continue
to grow and increase,

854
00:35:00,433 --> 00:35:02,533
and we can probably say so long

855
00:35:02,533 --> 00:35:05,400
to the soft-shell clam industry
as we know it.

856
00:35:06,500 --> 00:35:07,466
[Narrator]
Experiments like this

857
00:35:07,466 --> 00:35:08,633
may be the one of the only ways

858
00:35:08,633 --> 00:35:10,333
to preserve the fishery

859
00:35:10,333 --> 00:35:11,900
and a way of life...

860
00:35:11,900 --> 00:35:13,833
one mud flat at a time.

861
00:35:15,166 --> 00:35:16,300
[Brian Beal]
This is a protein source.

862
00:35:16,300 --> 00:35:17,500
This is a food.

863
00:35:17,500 --> 00:35:20,333
It's also a livelihood,
it's also a culture,

864
00:35:20,333 --> 00:35:21,333
so people should care

865
00:35:21,333 --> 00:35:22,733
because we would really like

866
00:35:22,733 --> 00:35:24,400
to have these mudflats

867
00:35:24,400 --> 00:35:26,966
contribute to the economy
of these coastal communities

868
00:35:26,966 --> 00:35:28,733
like they did way back when.

869
00:35:31,166 --> 00:35:32,900
[Narrator]
In a few months' time,

870
00:35:32,900 --> 00:35:34,033
the team will know

871
00:35:34,033 --> 00:35:36,166
if these baby clams
have a future.

872
00:35:37,500 --> 00:35:38,966
Meanwhile, warming water

873
00:35:38,966 --> 00:35:40,533
has changed the trajectory

874
00:35:40,533 --> 00:35:42,733
of almost all species
in the Gulf of Maine...

875
00:35:43,733 --> 00:35:45,500
...including a little bird

876
00:35:45,500 --> 00:35:46,900
that tells us a lot

877
00:35:46,900 --> 00:35:49,033
about the big ocean
beyond the gulf.

878
00:35:52,200 --> 00:35:54,733
About six miles
off the coast of New Hampshire

879
00:35:54,733 --> 00:35:56,700
lie White and Seavey Islands.

880
00:35:56,700 --> 00:35:58,666
There's little freshwater,

881
00:35:58,666 --> 00:36:00,300
not much vegetation,

882
00:36:00,300 --> 00:36:01,733
and hardly any food.

883
00:36:02,933 --> 00:36:05,466
Other than a handful
of scientists in the summer,

884
00:36:05,466 --> 00:36:07,900
no humans call this home.

885
00:36:07,900 --> 00:36:09,933
Even the lighthouse
is automated.

886
00:36:11,066 --> 00:36:13,033
It's basically
a big pile of rocks

887
00:36:13,033 --> 00:36:14,400
and some bushes...

888
00:36:15,400 --> 00:36:17,533
...the perfect summer home
for terns.

889
00:36:18,933 --> 00:36:20,533
At around 6,000 birds,

890
00:36:20,533 --> 00:36:23,233
it's the largest tern colony
in the Gulf of Maine.

891
00:36:25,233 --> 00:36:26,700
About a week old,

892
00:36:26,700 --> 00:36:28,033
this fragile tern chick

893
00:36:28,033 --> 00:36:29,633
weighs less
than a chicken nugget

894
00:36:29,633 --> 00:36:31,633
and is just
a couple of inches tall.

895
00:36:36,433 --> 00:36:39,766
A spotted down coat
keeps it warm and camouflaged.

896
00:36:41,266 --> 00:36:42,466
In about three weeks,

897
00:36:42,466 --> 00:36:44,466
she'll transform
from this ball of fluff

898
00:36:44,466 --> 00:36:46,200
into a flying bird.

899
00:36:47,700 --> 00:36:49,933
To get there,
she really needs one thing...

900
00:36:51,000 --> 00:36:52,100
...fish.

901
00:36:53,266 --> 00:36:54,966
Terns are migratory birds

902
00:36:54,966 --> 00:36:57,200
and travel thousands of miles
every year

903
00:36:57,200 --> 00:36:59,433
to return
to their nesting sites.

904
00:37:04,300 --> 00:37:06,966
Almost 90% of the birds
in the colony were born here.

905
00:37:08,933 --> 00:37:12,233
It's a network,
but it's not very social,

906
00:37:12,233 --> 00:37:15,800
because everyone in town
eats a lot of the same fish...

907
00:37:17,433 --> 00:37:20,366
...and every fish
that comes back is fair game.

908
00:37:20,366 --> 00:37:21,966
Fish get stolen...

909
00:37:24,000 --> 00:37:25,433
...stolen back.

910
00:37:26,666 --> 00:37:28,366
Adults steal from chicks...

911
00:37:31,666 --> 00:37:33,433
...and chicks learn from adults.

912
00:37:38,300 --> 00:37:41,166
In this community,
no one's passive-aggressive...

913
00:37:42,166 --> 00:37:44,000
...just aggressive.

914
00:37:49,666 --> 00:37:52,533
These terns have adapted
over millions of years

915
00:37:52,533 --> 00:37:55,766
to eat slender-bodied fish
like sandlance and herring.

916
00:37:57,833 --> 00:37:59,766
Just the right size
for a chick's beak.

917
00:38:06,733 --> 00:38:09,366
But as the Gulf of Maine's
waters have warmed,

918
00:38:09,366 --> 00:38:12,166
southern fish species
have migrated north,

919
00:38:12,166 --> 00:38:13,366
like butterfish--

920
00:38:13,366 --> 00:38:15,366
a perfectly good
source of protein,

921
00:38:15,366 --> 00:38:17,933
but the wrong shape and size.

922
00:38:27,866 --> 00:38:30,066
This chick is ravenous.

923
00:38:32,066 --> 00:38:35,900
If its parents can't catch it
the right fish,

924
00:38:35,900 --> 00:38:37,433
it could end up

925
00:38:37,433 --> 00:38:41,033
just another statistic
in Liz Craig's data.

926
00:38:43,066 --> 00:38:44,666
[Elizabeth Craig]
Our research on this island

927
00:38:44,666 --> 00:38:46,533
goes back 25 years,

928
00:38:46,533 --> 00:38:47,700
and over that period,

929
00:38:47,700 --> 00:38:49,800
we've seen
ocean temperatures increase

930
00:38:49,800 --> 00:38:51,433
and we've also seen changes

931
00:38:51,433 --> 00:38:55,100
in the proportion of
different fish over that time,

932
00:38:55,100 --> 00:38:57,033
and that includes butterfish,

933
00:38:57,033 --> 00:38:58,533
which is a warmer-water fish

934
00:38:58,533 --> 00:39:00,100
that has been
in the Gulf of Maine

935
00:39:00,100 --> 00:39:02,000
throughout this whole period

936
00:39:02,000 --> 00:39:03,600
but is starting to increase

937
00:39:03,600 --> 00:39:05,966
as the waters here
become warmer.

938
00:39:05,966 --> 00:39:07,466
So, the more butterfish

939
00:39:07,466 --> 00:39:09,466
the birds bring back
to feed their chicks,

940
00:39:09,466 --> 00:39:10,966
the slower the chicks grow

941
00:39:10,966 --> 00:39:15,166
because they're really not able
to swallow most of those fish.

942
00:39:15,166 --> 00:39:17,300
So we see that
as a real indicator

943
00:39:17,300 --> 00:39:18,833
of how warming ocean

944
00:39:18,833 --> 00:39:19,966
and how climate change

945
00:39:19,966 --> 00:39:22,500
is specifically impacting
these birds.

946
00:39:22,500 --> 00:39:23,966
[Narrator] Not only that,

947
00:39:23,966 --> 00:39:25,266
terns also tell us

948
00:39:25,266 --> 00:39:27,633
how the planet is changing
for all of us.

949
00:39:29,033 --> 00:39:32,566
[Craig] They're really valuable
to us as society

950
00:39:32,566 --> 00:39:34,766
by telling us
what's going on with our oceans.

951
00:39:34,766 --> 00:39:37,066
They are experiencing
all the same environment

952
00:39:37,066 --> 00:39:38,433
that we rely on.

953
00:39:38,433 --> 00:39:39,600
They're eating the same fish,

954
00:39:39,600 --> 00:39:41,300
they're swimming
in the same waters.

955
00:39:41,300 --> 00:39:42,900
So, yes, it's important

956
00:39:42,900 --> 00:39:44,900
that we do this work
to protect the birds,

957
00:39:44,900 --> 00:39:45,933
but what we're learning

958
00:39:45,933 --> 00:39:47,866
really tells us
about our own lives.

959
00:39:50,133 --> 00:39:52,000
[Narrator]
Getting data to track them

960
00:39:52,000 --> 00:39:53,733
and keep tabs on their growth

961
00:39:53,733 --> 00:39:54,766
requires banding

962
00:39:54,766 --> 00:39:58,200
many of the newborns
that hatch every summer.

963
00:39:58,200 --> 00:39:59,333
The team will band

964
00:39:59,333 --> 00:40:01,300
a total of 300 chicks
this season.

965
00:40:01,300 --> 00:40:03,133
[Craig] All right.

966
00:40:03,133 --> 00:40:05,466
The band is 1392.

967
00:40:05,466 --> 00:40:07,133
[Orena] 1392.

968
00:40:07,133 --> 00:40:09,100
[Craig] 63187.

969
00:40:09,100 --> 00:40:10,800
[Orena] 63187.

970
00:40:10,800 --> 00:40:13,433
So the wing is 55.

971
00:40:13,433 --> 00:40:14,666
[Willow] 55?

972
00:40:14,666 --> 00:40:16,666
[Orena] And the weight...

973
00:40:16,666 --> 00:40:18,733
[Craig] 65.

974
00:40:18,733 --> 00:40:20,166
[Willow] Oh, nice.

975
00:40:20,166 --> 00:40:21,900
[Orena] That's a good weight.

976
00:40:24,266 --> 00:40:25,800
[Craig]
So what we're looking at here,

977
00:40:25,800 --> 00:40:26,766
these--

978
00:40:26,766 --> 00:40:28,000
what we call "pin feathers"--

979
00:40:28,000 --> 00:40:30,333
they're going to turn into
the flight feathers of the bird.

980
00:40:30,333 --> 00:40:31,766
We're looking at
the length of these

981
00:40:31,766 --> 00:40:33,733
and also
their developmental stage

982
00:40:33,733 --> 00:40:35,766
in order to figure out
how old this bird is.

983
00:40:35,766 --> 00:40:37,066
So, as a group,

984
00:40:37,066 --> 00:40:39,333
we've decided
it's probably about 10 days old.

985
00:40:39,333 --> 00:40:40,433
It's a good bird.

986
00:40:40,433 --> 00:40:42,433
I'm very pleasantly surprised.

987
00:40:42,433 --> 00:40:44,000
[Orena] It's a healthy bird.

988
00:40:44,000 --> 00:40:45,033
[Narrator] It's a surprise

989
00:40:45,033 --> 00:40:46,300
because they're finding

990
00:40:46,300 --> 00:40:49,333
that many of the newborns
aren't doing as well...

991
00:40:49,333 --> 00:40:51,233
because the catch is changing.

992
00:40:51,233 --> 00:40:52,966
[Orena]
So, this is a butterfish.

993
00:40:52,966 --> 00:40:55,066
It's a lot wider than a herring.

994
00:40:55,066 --> 00:40:56,633
So, from the surface,

995
00:40:56,633 --> 00:41:00,100
if you see it
in the water like this,

996
00:41:00,100 --> 00:41:02,000
it might look like
a normal fish,

997
00:41:02,000 --> 00:41:03,466
but then when an adult
picks it up,

998
00:41:03,466 --> 00:41:05,066
it turns out to be really wide,

999
00:41:05,066 --> 00:41:07,400
and then the chick
has trouble swallowing it.

1000
00:41:07,400 --> 00:41:10,033
[Narrator] Liz and her team
can also learn from these birds

1001
00:41:10,033 --> 00:41:12,000
without seeing them.

1002
00:41:12,000 --> 00:41:14,366
They use tiny GPS tags

1003
00:41:14,366 --> 00:41:16,400
to track the birds
on their migrations.

1004
00:41:17,833 --> 00:41:20,200
The data reveals
a remarkable journey,

1005
00:41:20,200 --> 00:41:21,866
adding to the bigger picture

1006
00:41:21,866 --> 00:41:24,033
here in the Gulf of Maine
and beyond.

1007
00:41:26,066 --> 00:41:27,666
After departing
the Isles of Shoals

1008
00:41:27,666 --> 00:41:28,900
in late-August,

1009
00:41:28,900 --> 00:41:31,133
with a quick pit stop
in Cape Cod,

1010
00:41:31,133 --> 00:41:32,700
this bird made a week-long,

1011
00:41:32,700 --> 00:41:33,800
non-stop,

1012
00:41:33,800 --> 00:41:36,766
roughly 2000-mile flight
down to Venezuela,

1013
00:41:36,766 --> 00:41:39,166
averaging about
200 miles per day.

1014
00:41:39,166 --> 00:41:41,200
That's a lot
for this little birdie.

1015
00:41:42,666 --> 00:41:45,366
It wintered in Brazil
for eight well-earned months,

1016
00:41:45,366 --> 00:41:47,200
and in spring,

1017
00:41:47,200 --> 00:41:49,733
came back to the Shoals
to do it all over again.

1018
00:41:51,533 --> 00:41:52,800
[Craig] It's exciting

1019
00:41:52,800 --> 00:41:55,066
when you get to see a bird
that's come back here,

1020
00:41:55,066 --> 00:41:56,866
and it's 20 years old--

1021
00:41:56,866 --> 00:41:58,766
19, 20, 21 years old--

1022
00:41:58,766 --> 00:42:01,366
and it's been coming back here
year after year.

1023
00:42:01,366 --> 00:42:02,600
And you get to know
that individual--

1024
00:42:02,600 --> 00:42:04,400
and "Oh, it's back again
this year."

1025
00:42:04,400 --> 00:42:06,466
To me, that's the best feeling.

1026
00:42:06,466 --> 00:42:09,033
[Narrator] Soon, these birds
will head south

1027
00:42:09,033 --> 00:42:10,966
and the islands will go quiet.

1028
00:42:12,533 --> 00:42:13,766
[Craig] We're going to back off
from this bird

1029
00:42:13,766 --> 00:42:15,933
so it can find its home.

1030
00:42:20,866 --> 00:42:22,766
Some of them are adapting
better than others.

1031
00:42:22,766 --> 00:42:24,766
We see some terns

1032
00:42:24,766 --> 00:42:27,866
bring back no butterfish at all
for their chicks.

1033
00:42:30,133 --> 00:42:32,033
There will be more butterfish
in the environment,

1034
00:42:32,033 --> 00:42:33,466
but that doesn't
necessarily mean

1035
00:42:33,466 --> 00:42:36,166
that these birds are doomed
to eat butterfish forever.

1036
00:42:36,166 --> 00:42:38,400
They have the capacity to learn.

1037
00:42:39,600 --> 00:42:41,166
[Narrator]
As waters continue to warm,

1038
00:42:41,166 --> 00:42:43,733
everything in the gulf
will need to learn and adapt...

1039
00:42:44,866 --> 00:42:46,633
Gotta love our little landing
down here--

1040
00:42:46,633 --> 00:42:48,133
all natural.

1041
00:42:48,133 --> 00:42:49,766
[Narrator]
...something that the Cox family

1042
00:42:49,766 --> 00:42:51,133
knows all too well.

1043
00:42:51,133 --> 00:42:53,033
[starter purring]

1044
00:42:53,033 --> 00:42:54,700
[Andrew Cox] Nothing fancy.

1045
00:42:57,300 --> 00:42:58,566
[Narrator]
Folks along the Gulf of Maine

1046
00:42:58,566 --> 00:43:01,333
have been piecing life together
seasonally for years--

1047
00:43:01,333 --> 00:43:04,100
an early version
of the gig economy.

1048
00:43:05,266 --> 00:43:06,700
Winter might be scallops,

1049
00:43:06,700 --> 00:43:08,700
spring, lobsters,

1050
00:43:08,700 --> 00:43:10,166
and clamming year-round--

1051
00:43:10,166 --> 00:43:12,133
if you can keep
the green crabs in check.

1052
00:43:12,133 --> 00:43:13,933
[Johnny Cox]
Yeah, Harold is up on the top,

1053
00:43:13,933 --> 00:43:15,400
waiting for a ride.

1054
00:43:15,400 --> 00:43:17,033
[Andrew Cox] Yeah.

1055
00:43:20,133 --> 00:43:21,800
Climb aboard.

1056
00:43:21,800 --> 00:43:23,366
I thought
I would sit this one out.

1057
00:43:23,366 --> 00:43:25,100
[Andrew Cox] Oh, yeah?
Retirement again?

1058
00:43:29,533 --> 00:43:32,433
[Narrator] Johnny and Andrew
have had success lobstering,

1059
00:43:32,433 --> 00:43:34,933
but lately, something's off.

1060
00:43:36,066 --> 00:43:39,600
[Andrew Cox] Every yellow dot
is where my traps used to be.

1061
00:43:39,600 --> 00:43:41,533
I've moved a lot this year.

1062
00:43:41,533 --> 00:43:43,200
I got a lot of dots.

1063
00:43:43,200 --> 00:43:44,766
[laughs]

1064
00:43:44,766 --> 00:43:46,700
I've been trying to chase them.

1065
00:43:50,000 --> 00:43:51,600
No one home.

1066
00:43:51,600 --> 00:43:53,466
[Johnny Cox] I guess
they didn't like the menu.

1067
00:43:54,533 --> 00:43:56,200
Crabs and junk!

1068
00:43:56,200 --> 00:43:58,166
[Andrew Cox] All right.
Set her up!

1069
00:43:59,800 --> 00:44:01,066
When I was a kid,

1070
00:44:01,066 --> 00:44:02,500
we used to get a bucket,

1071
00:44:02,500 --> 00:44:05,500
two buckets of, like,
lobsters, easy.

1072
00:44:05,500 --> 00:44:07,566
Now, up in here,

1073
00:44:07,566 --> 00:44:10,900
you would be lucky to get
maybe three or four lobsters.

1074
00:44:10,900 --> 00:44:12,433
It could be

1075
00:44:12,433 --> 00:44:14,700
both the warming water
from climate change

1076
00:44:14,700 --> 00:44:17,433
and it could be another factor--

1077
00:44:17,433 --> 00:44:18,933
the green crabs invasive species

1078
00:44:18,933 --> 00:44:21,366
that we introduced
to our waters.

1079
00:44:21,366 --> 00:44:24,233
All those factors are impacting
our natural resources.

1080
00:44:24,233 --> 00:44:26,766
Yeah, that's
what I was afraid of.

1081
00:44:26,766 --> 00:44:28,833
Green crabs.

1082
00:44:28,833 --> 00:44:31,566
This is the invasive species
that eats everything.

1083
00:44:31,566 --> 00:44:32,700
[Johnny Cox] It's a problem!

1084
00:44:32,700 --> 00:44:34,500
I mean, they're going
to eat anything.

1085
00:44:34,500 --> 00:44:37,300
If you take a small lobster,
they'll eat it.

1086
00:44:37,300 --> 00:44:38,866
They ain't got no choice
in the menu.

1087
00:44:38,866 --> 00:44:40,200
They got to eat something.

1088
00:44:42,200 --> 00:44:43,433
[Andrew Cox]
That's out of three traps.

1089
00:44:43,433 --> 00:44:46,166
That's what is eating our stuff.

1090
00:44:51,733 --> 00:44:52,766
One.

1091
00:44:54,566 --> 00:44:55,933
[Johnny Cox]
Well, we're gaining.

1092
00:44:55,933 --> 00:44:57,966
We caught enough
for supper anyway.

1093
00:45:00,033 --> 00:45:01,433
[Narrator]
Being able to roll with change

1094
00:45:01,433 --> 00:45:04,933
is a must if you live
on the Gulf of Maine.

1095
00:45:04,933 --> 00:45:05,900
Working these waters

1096
00:45:05,900 --> 00:45:08,100
isn't just about
making a living,

1097
00:45:08,100 --> 00:45:09,700
it's a way of life.

1098
00:45:11,900 --> 00:45:14,333
[Andrew Cox] I did go to college
for four years.

1099
00:45:14,333 --> 00:45:15,800
I loved it.

1100
00:45:15,800 --> 00:45:17,133
But I really enjoy this.

1101
00:45:17,133 --> 00:45:19,966
I have a lot invested in this,
as you can tell--

1102
00:45:19,966 --> 00:45:22,066
these traps, the boat...

1103
00:45:22,066 --> 00:45:23,966
I've spent a lot of time
on this water,

1104
00:45:23,966 --> 00:45:25,866
learning the tides,

1105
00:45:25,866 --> 00:45:27,333
where the certain rocks are,

1106
00:45:27,333 --> 00:45:28,333
reefs.

1107
00:45:28,333 --> 00:45:30,166
I learned the hard way
a few times.

1108
00:45:30,166 --> 00:45:32,466
But no, I love it out here.

1109
00:45:32,466 --> 00:45:34,400
Especially days like today.

1110
00:45:34,400 --> 00:45:35,733
Nice and calm.

1111
00:45:35,733 --> 00:45:37,566
Nothing's broken down.

1112
00:45:37,566 --> 00:45:40,333
It's not a job sometimes
when you enjoy it.

1113
00:45:40,333 --> 00:45:42,500
Plus, I get to spend time
with the old man.

1114
00:45:45,133 --> 00:45:47,000
[Narrator]
But there's a growing fear

1115
00:45:47,000 --> 00:45:48,233
that green crabs

1116
00:45:48,233 --> 00:45:50,600
bring more change
than any fishery can handle,

1117
00:45:50,600 --> 00:45:52,800
whether it's lobsters or clams.

1118
00:45:57,766 --> 00:45:59,833
Back in Sipayik
four months later,

1119
00:45:59,833 --> 00:46:02,733
the clam gardeners
are checking on their seedlings.

1120
00:46:07,700 --> 00:46:10,066
[Beal] Okay, so we're just
hauling it right up.

1121
00:46:10,066 --> 00:46:11,700
[Narrator] Their clam seeds
have been watered

1122
00:46:11,700 --> 00:46:14,333
by nearly 300 tides

1123
00:46:14,333 --> 00:46:15,366
and they hope

1124
00:46:15,366 --> 00:46:17,200
that they've at least
doubled in size.

1125
00:46:17,200 --> 00:46:19,033
[Beal] All right,
so these are ready to come out.

1126
00:46:19,033 --> 00:46:20,400
Thanks, Thomas.

1127
00:46:23,466 --> 00:46:25,066
[Narrator]
This all comes down to timing.

1128
00:46:26,566 --> 00:46:27,900
By setting the boxes out

1129
00:46:27,900 --> 00:46:30,900
after green crabs are too big
to fit through the mesh cover,

1130
00:46:30,900 --> 00:46:32,466
they have a shot

1131
00:46:32,466 --> 00:46:35,800
at turning this mudflat
back into a clamflat.

1132
00:46:37,233 --> 00:46:38,666
[Beal] In the early '40s,

1133
00:46:38,666 --> 00:46:40,300
up to the early '50s,

1134
00:46:40,300 --> 00:46:42,300
clams used to be the king.

1135
00:46:42,300 --> 00:46:43,966
They used to be
more important economically

1136
00:46:43,966 --> 00:46:45,200
than lobsters.

1137
00:46:46,333 --> 00:46:47,666
But the problem is

1138
00:46:47,666 --> 00:46:50,366
that soft-shell clam landings
in Maine are at historic lows.

1139
00:46:50,366 --> 00:46:51,733
It's 2023

1140
00:46:51,733 --> 00:46:55,000
and the state has never seen
landings this low before.

1141
00:46:55,000 --> 00:46:57,166
There's not enough
to sustain a fishery.

1142
00:46:58,733 --> 00:47:00,133
[Narrator]
Within the past 50 years,

1143
00:47:00,133 --> 00:47:01,133
clam landings--

1144
00:47:01,133 --> 00:47:02,566
that's the total weight of clams

1145
00:47:02,566 --> 00:47:03,866
brought in
by commercial clammers

1146
00:47:03,866 --> 00:47:05,233
every year--

1147
00:47:05,233 --> 00:47:07,233
have dropped almost 90%...

1148
00:47:08,366 --> 00:47:10,200
...and the clammers
digging them out?

1149
00:47:10,200 --> 00:47:11,266
Three out of four

1150
00:47:11,266 --> 00:47:13,266
have left the flats entirely
for other work.

1151
00:47:14,100 --> 00:47:15,466
Brian Altvater knows

1152
00:47:15,466 --> 00:47:19,133
that planting clam seeds may be
one of their only ways forward.

1153
00:47:19,133 --> 00:47:20,766
[Altvater] So we got these nets,

1154
00:47:20,766 --> 00:47:24,100
and so there's 4,000 clams
in each one of these plots.

1155
00:47:24,100 --> 00:47:27,900
Well, you've got 50 plots,

1156
00:47:27,900 --> 00:47:30,733
4,000, you know, each,

1157
00:47:30,733 --> 00:47:32,633
so you do the math.

1158
00:47:32,633 --> 00:47:35,233
If this turns out
the way we're hoping,

1159
00:47:35,233 --> 00:47:37,733
we'll have
a crop of clams every year.

1160
00:47:37,733 --> 00:47:40,300
[Narrator]
And they're about to find out.

1161
00:47:40,300 --> 00:47:43,233
So I'm just scooping the mud.

1162
00:47:43,233 --> 00:47:46,866
We've got 111 more boxes
to do this morning.

1163
00:47:46,866 --> 00:47:48,733
This should have
green crabs in it,

1164
00:47:48,733 --> 00:47:49,866
but it doesn't,

1165
00:47:49,866 --> 00:47:51,700
so I'm happy, yeah.

1166
00:47:51,700 --> 00:47:53,966
[Narrator]
They got their timing right.

1167
00:47:53,966 --> 00:47:55,300
The garden boxes worked

1168
00:47:55,300 --> 00:47:56,766
and they now have

1169
00:47:56,766 --> 00:47:58,966
more than 100,000 seeds
to plant.

1170
00:48:01,800 --> 00:48:04,600
For the next five months,
the seeds are kept indoors.

1171
00:48:04,600 --> 00:48:06,433
[Beal] Goodbye!

1172
00:48:06,433 --> 00:48:09,533
[Narrator] Come spring,
it's finally planting season.

1173
00:48:09,533 --> 00:48:10,766
Now twice as big,

1174
00:48:10,766 --> 00:48:13,133
the clam seeds are going in
for the last time.

1175
00:48:17,333 --> 00:48:20,966
And like any garden,
it takes a lot of tending.

1176
00:48:20,966 --> 00:48:23,866
So we have 125 different plots.

1177
00:48:23,866 --> 00:48:26,466
All of them have 4,000 seed
in each plot,

1178
00:48:26,466 --> 00:48:27,833
so 500,000 clams

1179
00:48:27,833 --> 00:48:31,166
that we have planted
over a three-year span.

1180
00:48:31,166 --> 00:48:33,500
[Narrator] Erik Francis
is the steward

1181
00:48:33,500 --> 00:48:36,300
of the Sipayik Community
Clam Garden.

1182
00:48:36,300 --> 00:48:38,433
He doesn't
have to water anything,

1183
00:48:38,433 --> 00:48:40,700
but there is
plenty of weeding to do.

1184
00:48:40,700 --> 00:48:43,633
[Erik Francis] It is similar
to any garden on land.

1185
00:48:43,633 --> 00:48:45,966
Any garden
takes a lot of hard work.

1186
00:48:45,966 --> 00:48:48,133
We spend a lot of time
out here,

1187
00:48:48,133 --> 00:48:49,666
mainly moving seaweed,

1188
00:48:49,666 --> 00:48:52,166
just to prevent
the nets from being covered.

1189
00:48:54,166 --> 00:48:56,800
[Narrator] A covered net
could lead to a ripped net.

1190
00:48:56,800 --> 00:48:59,233
[Francis] This is the rip
caused by a storm,

1191
00:48:59,233 --> 00:49:01,766
which left
the whole net exposed,

1192
00:49:01,766 --> 00:49:03,733
so green crab
could climb under.

1193
00:49:03,733 --> 00:49:05,533
That's a buffet in there.

1194
00:49:05,533 --> 00:49:07,900
So what we're gonna do is
we're going to take the net,

1195
00:49:07,900 --> 00:49:09,200
and unseat it,

1196
00:49:09,200 --> 00:49:11,033
and replace it.

1197
00:49:11,033 --> 00:49:12,366
The green crab
are moving with that tide,

1198
00:49:12,366 --> 00:49:14,366
so we have to move
relatively quick

1199
00:49:14,366 --> 00:49:17,000
to put this net down
to protect all these clams.

1200
00:49:18,033 --> 00:49:20,500
[Narrator]
No staking required here,

1201
00:49:20,500 --> 00:49:21,900
a simple trench and backfill

1202
00:49:21,900 --> 00:49:24,200
can keep a net down
for about a year.

1203
00:49:26,166 --> 00:49:27,266
And while the clams grow,

1204
00:49:27,266 --> 00:49:30,300
Erik also tracks
public enemy number one.

1205
00:49:34,200 --> 00:49:35,266
We got some crab.

1206
00:49:35,266 --> 00:49:36,933
Now, what this one is,

1207
00:49:36,933 --> 00:49:39,200
is she's an egg-bearing female.

1208
00:49:39,200 --> 00:49:42,600
Every little dot and speck
is a future green crab.

1209
00:49:42,600 --> 00:49:46,166
She's carrying upwards
to 100,000 plus eggs.

1210
00:49:46,166 --> 00:49:49,233
So she's the main reason
that we have all the nets.

1211
00:49:49,233 --> 00:49:51,400
But this is just nature.

1212
00:49:51,400 --> 00:49:53,233
We're all just surviving
at the end of the day.

1213
00:49:53,233 --> 00:49:56,233
So they're doing
what they're supposed to do.

1214
00:49:56,233 --> 00:49:57,600
We're going to try to do
what we do

1215
00:49:57,600 --> 00:50:00,333
to have something to pass down
to the next generation.

1216
00:50:02,233 --> 00:50:04,066
[Narrator] The Gulf of Maine
has been changing

1217
00:50:04,066 --> 00:50:06,733
ever since its formation
thousands of years ago...

1218
00:50:08,333 --> 00:50:10,433
...but our role
in just a couple hundred years

1219
00:50:10,433 --> 00:50:12,500
has been profound...

1220
00:50:12,500 --> 00:50:13,833
altering the foodchain

1221
00:50:13,833 --> 00:50:15,300
and even ocean currents.

1222
00:50:16,400 --> 00:50:19,266
Its warmer waters
now determine who thrives

1223
00:50:19,266 --> 00:50:21,066
and who moves on.

1224
00:50:21,066 --> 00:50:23,433
[Fields]
These things have been honed

1225
00:50:23,433 --> 00:50:25,366
for hundreds
of thousands of years

1226
00:50:25,366 --> 00:50:27,766
to make the ecology
of this animal work,

1227
00:50:27,766 --> 00:50:29,866
and it can adapt to change,

1228
00:50:29,866 --> 00:50:32,600
but when you make change
really fast,

1229
00:50:32,600 --> 00:50:34,333
the populations can't keep up,

1230
00:50:34,333 --> 00:50:36,866
and they either end up
going extinct,

1231
00:50:36,866 --> 00:50:40,100
or having drastic moves
to the North or the South.

1232
00:50:42,600 --> 00:50:45,066
[Brown] There's going to be
ups and downs in any fishery.

1233
00:50:45,066 --> 00:50:48,166
What you want to watch out for
is overharvesting,

1234
00:50:48,166 --> 00:50:50,266
resulting in
recruitment failure,

1235
00:50:50,266 --> 00:50:51,833
resulting in lower catches,

1236
00:50:51,833 --> 00:50:53,600
resulting in a crashed fishery.

1237
00:50:53,600 --> 00:50:55,566
If we were to see
a major downturn,

1238
00:50:55,566 --> 00:50:57,600
we would know about it
well in advance,

1239
00:50:57,600 --> 00:50:58,900
and so that's really

1240
00:50:58,900 --> 00:51:01,400
the power of this project
up and down the coast.

1241
00:51:02,733 --> 00:51:04,600
[Narrator] So paying attention
to these animals

1242
00:51:04,600 --> 00:51:07,233
may reveal clues
of what's to come.

1243
00:51:08,666 --> 00:51:10,400
[Craig] They definitely
are similar

1244
00:51:10,400 --> 00:51:11,766
to the canary in the coal mine.

1245
00:51:11,766 --> 00:51:13,433
So what we learn
from these birds

1246
00:51:13,433 --> 00:51:14,700
tells us a lot

1247
00:51:14,700 --> 00:51:16,433
of what's happening
to the fish communities,

1248
00:51:16,433 --> 00:51:19,500
which are commercially important
to us here in the Gulf of Maine,

1249
00:51:19,500 --> 00:51:20,600
as well as just

1250
00:51:20,600 --> 00:51:22,933
the overall health
of our ocean systems.

1251
00:51:22,933 --> 00:51:26,633
[Narrator] The ingenuity
that decimated some species

1252
00:51:26,633 --> 00:51:29,800
is now leveraged
to save jobs and culture...

1253
00:51:29,800 --> 00:51:31,766
The clamming industry
is in jeopardy

1254
00:51:31,766 --> 00:51:33,333
and what we're trying to do

1255
00:51:33,333 --> 00:51:36,300
is something that communities
can grow their clams,

1256
00:51:36,300 --> 00:51:37,966
protect them from green crabs,

1257
00:51:37,966 --> 00:51:39,566
and then harvest them.

1258
00:51:39,566 --> 00:51:42,166
[Narrator] ...and maybe
the wisdom of 14,000 years

1259
00:51:42,166 --> 00:51:44,933
can guide us through
the most profound changes.

1260
00:51:46,066 --> 00:51:47,466
[Altvater]
We've always taken care

1261
00:51:47,466 --> 00:51:48,866
of the land and the sea.

1262
00:51:48,866 --> 00:51:50,633
It has sustained us,

1263
00:51:50,633 --> 00:51:52,033
it's taken care of us,

1264
00:51:52,033 --> 00:51:56,333
and we'll get back to taking
care of even the mudflats,

1265
00:51:56,333 --> 00:51:58,266
and they'll take care of us.

1266
00:51:58,266 --> 00:52:02,000
Take care of the fish,
the fish will feed us.

1267
00:52:02,000 --> 00:52:05,233
And the clams can be
the same way--

1268
00:52:05,233 --> 00:52:07,033
take care of them,

1269
00:52:07,033 --> 00:52:08,400
they'll take care of us.

1270
00:52:38,366 --> 00:52:40,200
