<div class="MsoNormal" style="text-indent: .5in;">
After snoozing my alarm for the
fifth time, it is hard to believe that it is 8 am. Opening the blinds, I do a
double take between my phone and the outside world. Am I sure it isn’t the
middle of the night? With one streetlight illuminating the vicinity, I can
barely make out the buildings next to us. It is pitch black outside. If we are
lucky today, we might see a slight glimmer of sunlight around noon. With two
cups of coffee in and more cups of tea waiting back at the duplex, Jun and I
embark on one of three trips per day to the aptly named Cakeeater shed. With
the pleasant humming of the instruments ringing in my head, there is one
pertinent question that I must ask Jun, “What’s for dinner?” <span style="mso-spacerun: yes;"> </span><o:p></o:p></div>

<div class="MsoNormal" style="text-indent: .5in;">
Between deciphering error messages
on the instruments and peeking outside for a glimpse of sunlight, food has
brought us comfort during the darkest days (literally). During the downtime,
I’m watching the food network as I hunch over a laptop analyzing our mass
spectra from the previous day. I make mental notes of my favorite meals before
strolling through the only large grocery store with fresh vegetables in
Utqiagvik. Surprisingly, the Alaska Commercial Company is fully stocked with a
bounty of options. You can even find exotic ingredients like bok choy and okra.
The prices are vastly different than what we would expect from Ann Arbor, MI
but by now we don’t blink twice at grabbing a $7 loaf of bread. <o:p></o:p></div>
<div class="MsoNormal" style="text-indent: .5in;">
Returning to the duplex with
hundreds of dollars in groceries, the difficult question arises again, what’s
for dinner? There are about 8 charming restaurants in the area but nothing
beats a home-cooked meal. We could make a hearty chili using the instant pot
provided for us, or a taste of Thanksgiving with a green bean casserole, or pancakes
and bacon because we are adults! Though our main concern is keeping our
instruments functional, we have spent the downtime during the past 6 weeks perfecting
our culinary skills. From cooking the perfect 135°F medium rare steak to
watching bread rise, I now feel as comfortable cooking as I do tuning the aerosol time-of-flight mass spectrometer (ATOFMS). With 25 mph winds and more
darkness ahead of us, we light a match to turn on the gas stove. <span style="mso-spacerun: yes;"> </span><span style="mso-spacerun: yes;"> </span><o:p></o:p></div>

Today, I make something that
reminds us both of home: wonton soup. Wrapping tiny spoonfuls of meat into a
paper-thin wrapper brings back nostalgic childhood memories of waking up early
Christmas morning to make wontons with my mom. With the darkness and wind
whispering for us to stay indoors, this will always bring us comfort and
warmth. With this meal, we bring a little bit of home to our new home in
Utqiagvik. <o:p></o:p></div>

Pratt Lab group members Jamy Lee and Jun Liu have been in Utqiagvik, Alaska since Oct. 28, and the sun went down for winter, with Polar Night beginning on Nov. 18. Jamy and Jun have been doing a great job keeping the ATOFMS going, while frequently dealing with getting stuck in snowbanks when going to/from the lab! It's been dark for quite a while, so the Pratt Lab decided to send them a care package! USPS flat rate shipments work to send mail to Utqiagvik, as long as you're patient! So, "3-day" shipping took 1 week, which is actually really fast for all the way to the North Slope of Alaska! They sent us the following photos of their excitement, with the message: "We received the package today! Thank you guys so much! These will keep us sane through the never-ending darkness!"</div>

Significant delays in fall sea ice freeze-up in the Chukchi and Beaufort
Seas are reducing winter sea ice extent and resulting in thinning sea ice prone
to fracturing. However, the majority of recent Arctic aerosol
observations have been made through intensive spring/summer field campaigns,
with few measurements in the fall-winter. This observational gap is limiting
our understanding of the spatial and temporal variability in the Arctic aerosol
population, as recognized by current international efforts focused on improving
understanding and prediction of the Polar Regions (e.g., Year of Polar
Prediction, International Global Atmospheric Chemistry Project activity CATCH (Cryosphere
and Atmospheric Chemistry)). The APUN field campaign will improve our understanding of atmospheric aerosol sources,
composition, and processes during the early Polar night. Pratt Lab PhD student Jamy Lee and post-doc Jun Liu are working hard to get our instruments ready to start sampling on the Arctic tundra!</span><br />

Welcome to the Pratt Lab!Kerri Pratthttp://www.blogger.com/profile/13900085999271964681noreply@blogger.com0tag:blogger.com,1999:blog-1572764306338673593.post-52474574551148902042018-08-22T08:27:00.000-07:002018-09-05T10:00:47.279-07:00A Day at the North Pole<br />
<div class="MsoNormal">
We spent several days breaking ice, which is quite a sensory
experience – a cacophony of smashing, grinding, and growling accompanied by
massive vibrations as this 100 m long, 10,000 ton ship slides over meter thick
ice and crushes it, sending chunks of ice past the propellers and around the
sides of the ship while traveling at a steady speed of 3 knots. But now, on Aug
12, we made it. We were all waiting in anticipation as we slowly traveled
farther north. Past latitudes 86, 87, 88, 89! deg N, every day taking me
further north than I have ever been before. Our main goal was the search for
the perfect ice floe on which to set up our sampling station for 5 weeks of
science. But as we past 88 deg, and then 89, it became apparent that we were
nearing the North Pole. And when you’re that close, you have to go! <o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
We paused for 24 hours at the pole, situated around 89 deg
58’ , for a North Pole science station. This was about 5 miles away from <i style="mso-bidi-font-style: normal;">THE</i> pole, blocked by a massive ice floe,
but when you’re that close, you’ve made it. <o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
We collected genuine North Pole water for an experiment,
sampled genuine North Pole air, and even tasted genuine North Pole ice
(refreshing, and slightly salty). <o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
This was also the perfect opportunity to get a group photo
on the ice in front of <i style="mso-bidi-font-style: normal;">Oden</i>.<o:p></o:p></div>
<div class="MsoNormal">
Then we got to celebrate! The captain invited everyone to a
toast on the ship’s bridge, followed by a 3-course dinner (and yes, we all had
to dress up!) It was an opportunity to take a break from the science and step
back, enjoying what a unique experience this is, and how lucky we all are to be
a part of it. Not many people can say they’ve been to the North Pole (and on my
first trip to the Arctic, no less!). And now I get to publish future papers
with <i style="mso-bidi-font-style: normal;">North Pole</i> data, how neat!</div>

<div class="MsoNormal">
Less than two days after departing from Longyearbyen, we
reached the marginal ice zone (MIZ), where the first small bits of sea ice
appear in the water. Being at sea, on such a large ship, is full of noises. The
<i style="mso-bidi-font-style: normal;">Oden, </i>being an icebreaker, isn’t
designed for open water. So the first leg of our journey was full of sound and
movement as the ship swayed back and forth, vibrating as it crashed through
waves. Along with the gentle swaying, the ship tends to sing – the noises were
curiously in tune, like an ethereal orchestra accompanying our expedition.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
But once we reached even the first bit of ice, the sound and
movement suddenly changed. The rocking stopped, the ship was much steadier
surrounded by ice, and all of a sudden it was much quieter. At this point,
experiencing such a drastic change, and looking outside to see ice moving all
around us, it was very clear that we were now in the Arctic. <o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
We paused in the MIZ for a 24 hour intensive sampling
period. This was very busy as everyone was working hard to run instruments and
conduct experiments only two days into the campaign. But this station was
essential – in order to establish a reference, in an area with open water and
some sea ice, to compare to our measurements once we got deep into the pack
ice. Sea ice defines the uniqueness of the Arctic environment – impacting the
ocean and atmosphere physics, biology, chemistry, and meteorology. <o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
As our science commenced, the novelty of our environment was
never lost to me, that we are in the Arctic Ocean, surrounded by sea ice,
looking out over a landscape that could be another world.<o:p></o:p></div>

Completing the transit from Helsingborg, we arrived at
Longyearbyen, Svalbard on July 28. This gave us a couple days to get off the
ship and explore before everyone joined for the official start of the
expedition. I made sure to enjoy my last chance to be on land for 8 weeks. <o:p></o:p></div>

<div class="MsoNormal">
I departed the U.S. on July 8 at the start of an adventure
that has taken me through Sweden, on a ship north to Svalbard, and then
continuing north, north, further north…<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The majority of this time will be spent aboard the Swedish
icebreaker <i style="mso-bidi-font-style: normal;">Oden, </i>as part of a joint
scientific venture between the United States National Science Foundation (NSF) and
the Swedish Polar Research Secretariat (SPRS) to support the Arctic Ocean 2018
campaign. Most of the scientific work onboard is being conducted under
the umbrella of the MOCCHA campaign (Microbiology – Ocean – Cloud Coupling in
the High Arctic). Research groups from the U.S., Sweden, and across Europe are
all studying different aspects of the complex Arctic climate, including air-sea
exchange, aerosol physics and chemistry, bubble physics, sea ice biology,
seawater chemistry, meteorology, and much more. It is an exciting, unique
opportunity to collaborate with many great scientists in order to better
understand the Arctic.</div>
<div class="MsoNormal">
<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Most of the science team gathered in Helsingborg, Sweden in
early July to meet <i style="mso-bidi-font-style: normal;">Oden</i> in port for
“mobilization”. This was a wild, busy four days of unpacking, organizing, and
setting up equipment on the ship to prepare for the expedition. I was lucky enough to then have a week to travel in Sweden
and Denmark before returning to the ship in Helsingborg on July 20 for the
“transit” to Svalbard. Only a few scientists for this early “preview” of the
expedition, allowing us 10 extra days to continue setting up our
instrumentation. This included many long days of troubleshooting, machining,
cleaning, and rebuilding parts of the sampling set up. But with everyone’s
help, it all came together in the end.</div>
<div class="MsoNormal">
<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The official start of the expedition (or research “cruise”
as we like to call it) began in Longyearbyen, Svalbard on Aug 1. There, the
rest of the scientists joined the ship, and we were ready to sail north. All
together, on the ship we total 23 crew members, 9 SPRS staff, and 41 scientists.
<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The goal is to travel north into the Arctic Ocean pack ice
(aiming for somewhere ~87 – 89 deg N), in order to find a large ice floe to
anchor <i style="mso-bidi-font-style: normal;">Oden</i> and set up an ice station
for scientific measurements. Stay tuned as we continue north and into the ice!<span style="mso-no-proof: yes;"> <o:p></o:p></span></div>
