Something
Is Seriously Wrong on the East Coast—and It's Killing All the Baby
Puffins

puffins, stray whales, invading sailfish: The North Atlantic is in a
bad way. Here's why.

THE
NEW POSTER CHILD for
climate change had his coming-out party in June 2012, when Petey the
puffin chick first went live into thousands of homes and schools all
over the world. The "Puffin
Cam" capturing baby Petey's every chirp had been set up on
Maine's Seal Island by Stephen Kress, "The Puffin Man," who
founded the Audubon Society's Project Puffin in 1973. Puffins, whose
orange bills and furrowed eyes make them look like penguins dressed
as sad clowns, used to nest on many islands off the Maine coast, but
300 years of hunting for their meat, eggs, and feathers nearly wiped
them out. Project Puffin transplanted young puffins from Newfoundland
to several islands in Maine, and after years of effort the colonies
were reestablished and the project became one of Audubon's great
success stories. By 2013, about 1,000 puffin pairs were nesting in
Maine.
Now,
thanks to a grant from the Annenberg Foundation, the Puffin Cam
offered new opportunities for research and outreach. Puffin parents
dote on their single chick, sheltering it in a two-foot burrow
beneath rocky ledges and bringing it piles of small fish each day.
Researchers would get to watch live puffin feeding behavior for the
first time, and schoolkids around the world would be falling for
Petey.
But
Kress soon noticed that something was wrong. Puffins dine primarily
on hake and herring, two teardrop-shaped fish that have always been
abundant in the Gulf of Maine. But Petey's parents brought him mostly
butterfish, which are shaped more like saucers. Kress watched Petey
repeatedly pick up butterfish and try to swallow them. The
video is absurd and tragic, because the butterfish is wider than
the little gray fluff ball, who keeps tossing his head back, trying
to choke down the fish, only to drop it, shaking with the effort.
Petey tries again and again, but he never manages it. For weeks, his
parents kept bringing him butterfish, and he kept struggling.
Eventually, he began moving less and less. On July 20, Petey expired
in front of a live audience. Puffin snuff.
"When
he died, there was a huge outcry from viewers," Kress tells me.
"But we thought, 'Well, that's nature.' They don't all live.
It's normal to have some chicks die." Puffins successfully raise
chicks 77 percent of the time, and Petey's parents had a good track
record; Kress assumed they were just unlucky. Then he checked the
other 64 burrows he was tracking: Only 31 percent had successfully
fledged. He saw dead chicks and piles of rotting butterfish
everywhere. "That," he says, "was the epiphany."
Why
would the veteran puffin parents of Maine start bringing their chicks
food they couldn't swallow? Only because they had no choice. Herring
and hake had dramatically declined in the waters surrounding Seal
Island, and by August, Kress had a pretty good idea why: The water
was much too hot.
ON
A MAP, the
Gulf of Maine looks like an unremarkable bulge of the North Atlantic,
but it is unique. A submerged ridge between Cape Cod and the tip of
Nova Scotia turns it into a nearly self-contained bowl. Warm water
surging up the East Coast glances off those banks and heads for
Europe, bypassing the Gulf of Maine and leaving it shockingly cold.
(I'm looking at you, Old Orchard Beach!) Meanwhile, frigid,
nutrient-rich water from off the coasts of Labrador and Nova Scotia
feeds into the Gulf through a deep channel and gets sucked into the
powerful counterclockwise currents. Whipped by that vortex, and
churned by the largest tides in the world (52 feet in one bay), the
Gulf of Maine acts like a giant blender, constantly whisking
nutrients up off the bottom, where they generally settle. At the
surface, microscopic plants called phytoplankton combine those
nutrients with the sunlight of the lengthening spring days to
reproduce like mad. That's how the thick, green soup that feeds the
Gulf's food web gets made. The soup is so cold that its diversity is
low, but the cold-water specialists that are adapted to it do
incredibly well.
At
least, they used to.
Like
much of the country, the Northeast experienced the warmest March on
record in 2012, and the year just stayed hot after that. Records
weren't merely shattered; they were ground into dust. Temperatures in
the Gulf of Maine, which has been warming faster than almost any
other marine environment on Earth, shot far higher than anyone had
ever recorded, and the place's personality changed. The spring bloom
of phytoplankton occurred exceptionally early, before most animals
were ready to take advantage of it. Lobsters shifted toward shore a
month ahead of schedule, leading to record landings and the lowest
prices in 18 years.
Hake
and herring, meanwhile, got the hell out of Dodge, heading for cooler
waters. In all, at least 14 Gulf of Maine fish species have been
shifting northward or deeper in search of relief. That left the
puffins little to feed their chicks except butterfish, a more
southerly species that has recently proliferated in the Gulf.
Butterfish have also been growing larger during the past few years of
intense warmth, and that, thinks Stephen Kress, might be a key. "Fish
start growing in response to changes in water temperature and food,"
he says. "The earlier that cycle starts, the bigger they're
gonna be. What seems to have happened in 2012 is that the butterfish
got a head start on the puffins. If it was a little smaller, the
butterfish might actually be a fine meal for a puffin chick. But if
it's too big, then it's just the opposite. That's one of the
interesting things about climate change. It's the slight nuances that
can have huge effects on species."
LIFE
WOULD GO ON
without puffins. Unfortunately, these clowns of the sea seem to be
the canaries in the western Atlantic coal mine. Their decline is an
ominous sign in a system that supports everything from the last 400
North Atlantic right whales to the $2 billion lobster industry.
The
next sign of deep weirdness arrived in December 2012, when Florida
beachcombers began spotting hundreds of what appeared to be penguins
soaring above the Miami surf. They
turned out to be razorbills, close relatives of puffins that also
call the Gulf of Maine home.
Razorbills
should be high on your reincarnation wish list. Superb fliers, they
can also plunge into the sea and pursue fish underwater by flapping
their wings—while dressed in black tie. James Bond, eat your heart
out.
But
normally, they do all this in the North Atlantic. Suddenly thousands
of them had decided to move to Florida. The consensus was that they
had simply kept going in a desperate attempt to find food—and that
it couldn't end well for them. It didn't. By early 2013, hundreds of
dead razorbills had washed up along East Coast beaches, most
emaciated. So did 40 puffins. "That's very rare," Kress
says. In fact, finding even a single dead puffin on the beach is
unusual. "They're tough little guys! They'll live 30 years or
more."
The
weirdness continued. In the spring of 2013, the National Oceanic and
Atmospheric Administration made its semiannual trawl survey of the
Gulf of Maine, dragging a net at dozens of points throughout the Gulf
and counting, weighing, and measuring everything caught. There were
plenty of butterfish and mountains of spiny dogfish, a small shark
that used to be relatively rare in the Gulf of Maine but now owns the
place. There were very few cod, the fish that made New England, that
lured thousands of fishing boats from Europe, that fed millions of
people over the centuries. NOAA slashed the 2013 quota for cod to a
pittance, putting hundreds of enraged fishermen out of work.
In
recent history, the average ocean surface temperature of the Gulf of
Maine has hovered around 44 degrees Fahrenheit. 2013 was the
second-warmest year in the Gulf in three decades, with an average
surface temperature of 46.6 degrees. But it was nowhere near the
freakish spike to 47.5 degrees in 2012, and the phytoplankton did not
repeat its crazy early bloom. Instead, it didn't bloom at all. "So
poorly developed, its extent was below detection limits" was how
NOAA put it in its Ecosystem
Advisory, sounding surprisingly calm, considering it was saying
the marine equivalent of "No grass sprouted in New England this
year." Phytoplankton feeds some tiny fish and shrimp directly,
but more often it feeds zooplankton, the bugs of the sea, and these
in turn feed everything from herring to whales. The undetectable
phytoplankton bloom did not bode well for zooplankton, and sure
enough, that spring NOAA
broke the grim news: "The biomass of zooplankton was the
lowest on record." Even this dirge doesn't do justice to the
dramatic deviation from the organisms' historical norm: Their numbers
bounced along in a comfortable range for 35 years before taking a
gut-wrenching nosedive in 2013.
By
the time of that announcement, Project Puffin was starting its 2013
season. With spring temperatures closer to normal, Kress had hoped
that his Seal Island puffins would return to their fruitful ways, but
only two-thirds of the colony showed up. Still, a new chick was
chosen for the Puffin Cam feed, and viewers named her Hope. For a
while, all went well. Kress saw fewer butterfish being delivered, and
Hope flourished. But soon Kress noticed that fewer birds than usual
were hanging out at the Loafing Ledge, a rocky ridge where the
parents socialize between feedings. Then he realized that the time
between chick feedings was considerably longer than normal. The
puffins were having to range much farther to find fish.
Too
far, as it turned out. Although Hope successfully fledged on August
21, she was one of the few lucky ones. Only 10 percent of the puffin
chicks survived in 2013—the worst year on record. "We've never
seen two down years like this," Kress told me. "The puffins
really tanked."
And
how could they not? The Gulf of Maine, the great food processor of
the western Atlantic, was almost out of food.
USUALLY,
A SYSTEM as
large and complex as the Gulf of Maine, sloshing with natural noise
and randomness, will disappoint any human desire to fit it into a
tidy narrative. It can take years to tease a clear trend out of the
data. But by late 2013, things were so skewed that you could see the
canaries dropping everywhere you looked.
November
30: Researchers announced that instead of the dozens of endangered
right whales they normally spot in the Gulf of Maine during their
fall aerial survey, they
had spotted...one. They were quick to note that the whales
couldn't all be dead, just missing—probably off in search of food.
Sure enough, in January 2014, 12 of the same species of whale were
spotted in Cape Cod Bay, where food is more plentiful.
By
now, you'll have no trouble filling in this sentence from the
December 4 Portland
Press Herald:
"This summer, a survey indicated that the northern shrimp stock
was at its ____ ____ since the annual trawl survey began in 1984."
That's right: lowest level. In fact, the sweet Gulf of Maine shrimp—a
closely guarded secret in New England—had collapsed so completely
that regulators closed the 2014 season and warned of "little
prospect of recovery in the near future." It takes shrimp four
to five years to reach harvest size, and few of the shrimp born in
the Gulf of Maine since 2009 have survived. If shrimp miraculously
produce a bumper crop this year, there might be a few to eat in 2018.
In the meantime, throw some butterfish on the barbie.
Or
maybe sailfish or cobia, two Florida species hooked by bewildered New
England anglers in 2013. The Gulf of Maine Research Institute
scrambled to find a bright side, publishing a paper (PDF)
on the commercial potential of former Virginia standbys like black
sea bass, longfin squid, and scup, which are new regulars in the
Gulf. Admirable adaptability, and undoubtedly a few quick-moving
fishermen will profit from the regime change. But I don't relish life
in a world where only the hyperadapters survive.
"A
puffin is an excellent example of a specialist bird that is going to
be vulnerable to climate change," Kress says. "For a
specialist bird like a warbler or a seabird, which relies on a small
range of foods but lives in a vast area, if something goes wrong
anywhere in the migratory range of that bird, it's in big trouble.
And its ability to adapt is less than a bird with a more generalist
lifestyle like a gull or a crow. Those highly adaptive birds are
going to have the advantage in the long run. We see that vividly with
the pictures of Petey trying to wolf down that oversized butterfish.
It's scary. But it's a glimpse into a possible future."
Or
present. We tend to think of climate change as incremental and
inexorable, like seeing old friends age at the annual reunion. There
are some new wrinkles, a step has been lost, and you know there's no
going back, but at least you can still look forward to years of
friendship. But ecosystems are wired with tipping points. A tweak
here and there can make things unrecognizable tomorrow. Glaciers
melt. Forests
ignite. And suddenly your old pal isn't answering her phone
anymore.
Yes,
we can adapt. Us and the gulls and the rats. But it will be awfully
lonely out there.
For
40 years, Stephen Kress has traveled to the same Maine islands each
spring, has watched the same puffin couples return year after year to
raise their chicks. Now he doesn't know what to think. "I've
seen colonies go up and down, and I know one year doesn't make a
pattern, but you can't help but wonder. We've worked decades to build
those populations up, and in 2013 we lost a third. That's pretty
dramatic."
Still,
Kress, who calls himself a perennial optimist ("Who else would
start Project Puffin?"), will head back out this May, on the
heels of this winter's cold snap. He plans to outfit a few birds with
GPS devices in hopes of finding the key places where they feed and
overwinter. Perhaps there are new refuges to be found, places just a
little colder or more resilient, where a puffin can still be a
puffin. In May, the Puffin Cam will go live, a new chick will get a
new name, and a fresh batch of schoolkids will tune in to get a look
at their brave new world.
Climate change and acidification are only one aspects of human overshoot on this planet. Over harvesting and resource extraction, habitat destruction and pollution are all existential threats on land as well as in the water.
