Summer Season Preparations
Sunday, 15 October 2000
Sorry for the long delay in writing. It has been
a busy time in McMurdo Station. Two weeks ago I had to move from
dormitory 201 to dormitory 210 to get ready for the summer season.
I knew this was going to be coming up so I did not really get
unpacked the whole time I have been here. Everything except the
bare necessities had been in boxes. We only have Sundays off so
that was moving day. Many people had to move that day so it seemed
everyone was carrying boxes and furniture to their rooms. If
someone has something they don't want they put it outside their
rooms and someone else will take it and use it. You have to keep
making the rounds to find the things you might be looking for, but
you can usually get something close. Pack rat that I am, I had
quite a lot of stuff to move. I even left boxes of things down
here in storage from last season. It is amazing what you can
accumulate. I got everything put in on Sunday. In the few evening
hours that are available, I have been unpacking and organizing.
Last Sunday I got one of the carpenters to
build me a loft for my bed. The dorm I am in now has rather high
ceilings, so that is a good bit of wasted space. Under the loft
I have an office set up. I have a desk for my computer, a table
for the printer, a set of bookshelves, etc. So I feel right at
home now. The loft is high enough that I can walk underneath it
without hitting my head and there is still plenty of room in the
bed for me to even sit up on my knees and not come close to hitting
the ceiling. I like it a lot. I have a ladder to climb up and down
with, but when I am not using it, it stores out of the way. Quite
nice. I still need to spend a little time organizing things, but
I think it is going to be quite comfortable.
The summer season is beginning. There will
suddenly be about 900 new faces around here. I have to say that
I have really enjoyed the early season with only 350 people on
station. Moving was only one of our preparations. Getting the
runway prepared was and continues to be a big job. The Ice runway
is only a couple of miles outside of town on the sea ice. This
ice is only a few meters thick and will melt before the end of
the summer. However, at the moment it is thick enough to land
planes on so it makes a convenient location for an airport. Any
cracks that form have to be mended.
There are many heavy machines out there
surfacing the ice. I love to watch the big snow–blowers
shoot the snow way up into the air. They spent several weeks
working on the runway just before the condition one storms we
had a few weeks ago. After the storm the runway was covered in
snow again and it was almost back to square one.
We had to go out and set out the runway lights and then run miles
of cables to everything.
There are also the Precision Approach Path Indicator (PAPI) lights
that we have to set up. Those help guide the pilots. One set has
to be at an angle of 2 degrees, 15 minutes and the other has to be
at 2 degrees, 45 minutes. If they are slightly off they stop
working. These help the pilots gauge their altitude over the ice.
Those are powered by gas generators so we have to take fuel out to
them every time we are expecting planes in.
Sometimes when you are out on the ice runway
there are many mirages off in the distance near the mountains. It
looks as though there are mesas and glaciers that aren't really
there. Around here they are called Fata Morganas.
Three airplanes have landed here so far. Then
the weather got foggy. It has been almost a week since we have had
any more planes in. The first plane was a C–141 like what I
flew down here on. The other flights have been on the C–17.
After setting up the runway lights we stayed out there to watch
the C–17 land. It is a very impressive plane. (Notice the fata
morgana in the first of the C–17 photos)
We have another airport called Williams Field,
or Willy Field for short. It is located on the permanent sea ice
of the Ross Ice Shelf. That ice is over 300 feet thick. It has
many layers of snow on it and only planes with skis will be able
to land there. We will not officially move our airport out there
until December when it is no longer safe to use the Ice Runway.
However, before that time several science groups make use of Willy
Field. Consequently we are preparing that area as well. There are
several permanent buildings out there. During the winter they
become completely buried in the snow and have to be dug out with
bulldozers. In the photo below, what you see is the roof of
one of the buildings which is completely buried!
They are building roads out at Willy Field as
well as at the Ice Runway. On the Ice Runway the roads and the
runways are directly on the ice. They only scrape off the snow
and make sure that the ice is smooth and without cracks. At Willy
Field there is a much deeper layer of snow. The roads and runways
are all on the snow. After the roads are prepped and before they
are set up, it is quite easy for our trucks to get stuck in the
snow. We then have to get one of the heavy equipment operators to
come over and pull us out. On the ice shelf things like weight
in the back of your vehicle or chains on your tires actually make
things worse. Most roads with this much snow have some kind of
earth or pavement underneath them. The snow here is so deep that
those things just drive you in further.
In preparation for the science teams which will
be arriving soon, we had to set up the generators out at Willy
Field. We have 2 12kw generators to run the whole area.
The carpenters went out and put up a couple of jamesways which
will be used as research facilities for the science teams, for
berthing and as a galley. Then we have to go in and run power for
them. The linemen will get power to the building, but then we put
in a temporary service, lights and receptacles.
As I mentioned before, we have had quite a bit
of ground fog. It usually clears by the afternoon, but sometimes
it doesn't. The planes cannot land here in those conditions.
Several flights have taken off from Christchurch and had to turn
back due to the fog.
This fog we have been having is made up of thin, multi–layered
clouds of ice crystals. A very interesting phenomenon in this fog
is Sun dogs. These are more accurately named parhelions. They are "
mock" suns caused when the light from the sun is refracted and
reflected by the ice crystals in the air.
There is a hill in town named Observation Hill,
or Ob Hill as everyone calls it. It isn't terribly high, just
slightly over 700 feet, but it is a pretty steep walk. There is
not any climbing involved, just walking. It is covered with snow
and ice so it really adds to the challenge. I can manage to get
up fairly well, but I usually end up sliding down. Sometimes it is
fun, but on the icy bits it can get pretty scary because you can't
stop until you hit a rock.
Castle rock is another place we can go climbing.
It is much more to my liking as there is more scrambling involved.
However, Castle Rock is 2 miles away and you have to sign out at
the firehouse and have a buddy with you in order to go. Ob Hill
is much more accessible.
