| Allison Bailey '07 studies a seabird in the
Arctic. Opportunities for student research, conducted near and
far, are plentiful at Pomona. |
Nina Karnovsky, an assistant professor of biology, has been
traveling to the Arctic since 1997 to study seabirds. For the past
two summers, she has taken a Pomona student along on her summer
research expeditions.

Change with Global Climate Change
The Location
The Polish Polar Station, Polar Bear Bay, Hornsund Fjord,
Spitsbergen Island, Norway
Allison Bailey '07, a biology major, was the
latest field assistant to spend four weeks at the Polish Polar
Station.
Bailey: I grew up in Livermore, home
to a nuclear lab, wine grapes and cowboys. My dad, who is a high
school biology teacher, got me interested in the natural world by
taking me hiking and on camping trips to Yosemite. I also had an
excellent AP bio teacher in high school.
Karnovsky: I was not at all interested
in science and even petitioned out of my science classes when I was
at Wesleyan. My epiphany came after I graduated, when I came to
California and got at job at Point Reyes Bird Observatory teaching
kids about birds. I fell in love with research and started taking
seasonal jobs, studying Goshawks in the Grand Canyon, elephant seals
on the Farallon Islands and sea turtles in Hawaii. Ten years ago, I
started working in the Arctic, which is where I did the research for
my Ph.D.
B: I grew up hearing about the close
relationships that my grandparents (professors at Scripps and
Pomona) had with their students— enjoying discussions, having
dinners for students at their house, keeping in contact with their
advisees after graduation. I came here because I wanted to have that
same kind of academic interaction. After my sophomore year, I spent
part of the summer studying birds in the Eastern Sierras with
Professor Levin [Rachel Levin, associate professor of biology]. Then
I took a vertebrate biology course from Professor Karnovsky before
heading to South Africa for my semester abroad. I was in South
Africa, sitting in this little Internet café in the heat of the
summer, when I got an e-mail from her asking me to be her research assistant. I was
ecstatic. I
didn’t have to think twice about accepting the job.
K: I could see Allison had the qualities I look for in a field
assistant. She was
enthusiastic, easy to get along with, and good at designing
projects—I have
students in all my classes design their own fieldwork and carry it
out. I
thought she’d be a great candidate and I was right.
getting there
K: We flew from California to Newark to Oslo to the northern tip
of Norway. Then it was on
to Longyearbyen and a two-day boat trip down to the Polish Polar
Station.
B: There are about 25 people at the station in the summer, 10 in the
winter. While we
were there, people were coming and going – scientists from Belgium
and Norway, Spanish
glaciologists. Most of the researchers are from Poland.
K: One of the things I love about polar research is that it’s so
international. That’s another
reason I chose Allison because I knew she would enjoy the social
part of the experience
because she was making the most of her study abroad experience in
South Africa.
The Research
K: When I went to the Antarctic in 1992 I realized how any
change in the food web is quickly transmitted to birds. They’re
responsive to changes in ice conditions and warming, and that
changes their behavior, which is something we can measure.

B: Because little auks eat plankton, they’re good indicators of
what’s happening in the ocean. What’s cool about the place
where we were is that there are two currents. In addition to
being different temperatures, they have different types of
plankton. When there’s a lot of warm water and just a slice of
cold, the little auks mostly feed on the small plankton. When
the cold current dominates, you get a lot of energy-rich prey.
We have data for several years on where the currents are,
where the zooplankton are and what the currents are doing.
K: With such a short-term study we haven’t measured huge
declines in productivity, but one of the things we’re doing is
comparing our colony, which has a lot of warm water around
it, to another colony in Greenland—same species of bird—
surrounded by a lot of cold water.
B: Capturing the chicks and adult birds for measurements
doesn’t require any special techniques. The chicks nest in rock
crevices and you have to just reach in and grab them. The
adults, which look like small penguins but can fly, require
a net.
K: It’s daylight all the time when we’re there so we have to
keep working because the birds don’t stop. A lot of people
have a romanticized idea of what field research will be like. It
takes a lot of perseverance – conditions can be really
uncomfortable and animals don’t behave like you think they
might. Having this experience while you’re an undergraduate
helps when you need to make a decision about whether to go
to grad school in an area that involves field work.
B: We also spent three days on a large three-masted sailboat
that took us out to sea to collect samples in the currents of
cold and warm water where the auks find their food. You can
be sitting on the deck counting birds...nothing, one, nothing,
nothing…3,400!
back to pomona
K: “I’m happy I can give my students an opportunity to experience
all levels
of a project. Allison was in the field for the data collection and
has been
helping with the analyses and doing her own analysis for her senior
thesis.
She wrote a poster and presented it at the Pacific Seabird Group
meeting,
where she got an honorable mention. A few people asked when she was
going to get her Ph.D. I told them she was just graduating from
college.”
B: “It’s been very cool. In addition to learning about biology, it’s
been
interesting to make the connection between climate and predators.
I’ve
also appreciated having a role model
like Professor Karnovsky. To have strong
women scientists in this department,
who can do so many different things,
is awesome.”
The “Arctic Flu”
Allison was awarded a Fulbright to return
to the Arctic to study at the university in Longyearbyen, where she’ll look at the
relationship between migrating geese and
plants of the tundra and how they are
affected by climate change. She’ll
probably cross paths with Laurel
McFadden ‘06, who also spent a summer
as a research assistant for Karnovsky and
was awarded a Watson Fellowship to
photograph people north of the Arctic
Circle. Karnovsky will also go back, this
time with three students from Pomona.
They will all be there for the International
Polar Year, a collaborative international
effort to study the polar regions that
takes place every 50 years.
K: Every student I bring to the Arctic gets
the “Arctic flu.” You catch the bug and
you have to go back. It becomes a part of
you. One of the things I love about it
that’s different from the Antarctic is that
there are all these wildflowers and land
mammals, in addition to the huge
number of seabirds. It’s extraordinarily
beautiful – harsh, stark, but full of color.
