As many of the locals and the Barrow NARL regulars continued
to tell us, mother nature couldn’t have given Claire, Nate, and I a better
trip! After our exceptional day on Tuesday (warm weather, polar bears, and
caribou!), we did experience some of the high winds of Barrow on
Wednesday, preventing us from heading out onto the sea ice on the snowmobiles.
Despite this, we still headed out to the ‘cake eater’ lab where Angela Raso
(check out her blog! --->
Snowkidding.blogspot.com) is doing her PhD research on fluxes of halogen
species from the snow pack. There, we had the chance to collect samples of the
tundra snow!

On Thursday, blessed with another full day of low winds and
good visibility, we headed back out on the Atlantic ocean! Although we didn’t
see any bears or caribou, we did get lots and lots of snow! With two days of
practice behind us, we were seasoned snow collectors. We had become so
efficient, that we managed to stop and take transects at five different
locations! Our coolers are filling up quick!

Friday, our last day, was forecast to have 25 mph winds
and thus extremely uncomfortable temperatures. Dejected, we sat in our hut most
of the morning. Productive as we were organizing all our pictures and records,
we could not have been happier to get a surprise call from Dr. Pratt informing
us that the conditions had dramatically improved! It was as if the sun came out
just for us! We rushed out to the sea ice to get our last round of samples and
to say goodbye to the beautiful Alaskan winter landscape. What an experience
this has been.

In all, we collected just under 100
snow samples! We could not have had a better turn out, and next year’s Chem
125- Authentic Research in Snow Chemistry students have a boatload of knowledge
to gain from these sample analyses. With 8 full transects (including depth
profiles) of snow samples extending from land to the very edge of Elson Lagoon,
two full transects on actual ‘sea ice’, and both vertical and perpendicular (to
wind) transects of tundra snow, students will clearly be able to see the
changing snow chemistry and factors that influence it.
Personally, though, I just can’t
wait to analyze these samples with ion chromatography! I have seen
countless chloride, bromide, and sodium concentrations, numerous pH readings,
and too many ion ratios to count, but I have never gotten to be on the other
side- to reap the benefits of my own hard labor. Essentially going from start
to finish, connecting all the dots. This is the closest I have ever gotten to
making a real impact, and the feeling is much more exhilarating than I could
have ever imagined. I am incredibly grateful that Dr. Pratt and our funders (Howard Hughes Medical Institute, University of Michigan Department of Chemistry, University of Michigan Program in the Environment, University of Michigan Arctic Internships, and National Science Foundation)
made such an enormous effort to make this happen. As I am finally
getting to make my mark on the world, this trip has sure made its mark on me.
