25 January, 1997
It is another gray day in the Taylor Valley with the temperature at -4
celcius. The skies here look much like Seattle with many shades of that
wonderful gray. Clouds are low, but I know it will not rain, maybe snow!
As I plan for the day's activities I am aware that this field camp must
be closed down for the season. Most of the scientific equipment gets
packaged up and returned to the Crary Lab for the winter. This means that
time is limited for microscope use since they too must be sent back in a
few days. I am sharing with Emily, the graduate student who is studying
the ciliates and flagelates in all of the lakes in this valley and Dr. Kepner
who is looking at and enumeration some virus like parcticles that we think are
viruses. He has at least 4 days worth of counting parcticles on his slides
using much the same techinques that I have been using, that is, counting by
using the epiflourescent microscope. His samples have been stained with a dye
called yo-pro that stains nucleic acids. I believe he is the first person
to have looked at virus like parcticles as a possible source of carbon in
the dry valley lakes. He still needs to get a scanning electron
microscope picture of these parcticles to show that they are really
viruses. Until then, he calls them virus like parcticles. There is a high
demand for time on the microscope. Knowing this, I have volunteered to go
back to McMurdo Station and use the microscopes in the Crary Lab to finish my
work on the rotifers. After much discussion because both Ray and Em
really needed to use the microscope and because they really wanted me to
feel included and part of the team, we agreed that I could do my work
easily at the Crary Lab while they needed to stay at the Lake Hoare field
camp to help with closing as well as to collect more samples. I assured
them that I really did feel included, a team member and as part of the
team, I could use the scopes full time at Crary with no competition.
Thus, I was allowed to consider asking for a helo for late on Saturday.
The helo was scheduled to arrive sometime after 4:00 p.m. so I have most
of the day to collect any additional samples that I need and prepare any
further FLMs and FLOs. I then have to pack up my tent! What a daunting
task. I have the two orange duffle bags from ASA, my own bag and the
sleep kit to organize. Once packed, I bag drag out to the upper helo pad
and my things join the ever growing pile of items to be taken back to
McMurdo. The kiwis are also leaving today and they have a mountain of
items that are packed into a sling load. As they prepare to leave, the
helo slowly lifts off and suddenly the sling opens dropping their gear all
over the place! Sleeping bags and tent become airborn as the helo slowly lands
again. Even the weighted down items from the retro pile start to become
airborn. The helo props quickly slow down and we all begin the retrieval
process and repack the sling. Then Paula the magnificent, the camp
manager, goes up to the helo and hooks the sling rope to the belly of
the helo while the blades are whirling, sand flying and air vibrating with
the noise. Lift off again and we all hold our breath.Its up and away this
time, whew!
I then collect my last mat sample and package up the supplies that I will
need at Crary Lab. I take a walk around the camp and out onto the
ice of Lake Hoare. This is truly a unique and wonderful place. The air
is crisp with a strong breeze blowing and mostly cloudy skies give the
warning of winter's approach. The sun dips behind the peaks for longer
periods of time. The feeling of summer in the dry valley is gone for this
year. I feel lucky to have had some time here to share the science and
the experience in Antarctica. I am not ready to leave yet, not having
garnered enough of the essence of the valley into my pores. I hear the
helo coming, so I must be off. Will I ever be back? Dr. Kepner asked me to
consider returning for the season next year - hmmmmmm. It seems that my
lab skills have met with his approval
The helo ride back to McMurdo Station included a fueling stop at Marble
Point, a pick up at Lake Frixell and a return along the ice edge. I am
surprised at how much sea ice has melted in the two weeks since I first
flew over this area. Large cracks can be seen over the entire
surface. The area looks like a huge jigsaw puzzle being pulled apart from
all directions. The water is deep blue with huge icebergs, the sky a lighter
shade blue. Seals lie about on the floating ice in small groups.
I saw at least a dozen orca whales feeding close to the ice edge. There are
penguins who seem to be waving at us as we fly low over the ice and have
a wonderful view of the whole sound. The pilot seems to enjoy our excitment
at having a chance to see the wild life and does his best to point out
more whales, seals and penguins.
Back at McMurdo, a room is waiting for me at Hotel California, but I have
missed the dinner hour. I really don't mind since I still have plenty of
snickers bars left over from field camp. People rely on snickers as a
staple for energy. ( It is not considered a snack)
Tomorrow I will be in the Crary Lab.
