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.
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. 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 of 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 the run power to 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.
