Notes
from the Antarctic
Desert
Flat and white as far as the eye can see. The sun is shining and the
glare from the ground burns your eyes. This is the view from on top of Law
Dome in Antarctica, the driest, coldest and windiest continent.
You pull up your collar and face the wind, which chills you to the core.
Your eyes are hurting from the intense cold and cutting force of the wind;
your fingers feel as thick as sausage rolls inside your lambswool-lined
gloves. Beneath your thick wind-resistant coat you have several layers of
clothing through which the wind still bites. Your toes are numb inside your
thick rubber and lambswool-lined boots, your socks are pulled up nearly to
your knees and your lips and ears are tingling.
The temperature has been below zero for the past eight months, at times
as low as minus 30 degrees Celsius. Snowfalls are regular and the ground is
covered with snow and ice several metres thick. Near the coast, there are
occasional rock outcrops that are jagged and harsh and stand as the only
resistance to the bitter katabatic winds, which scour the land continually
throughout winter.
Casey Station becomes my home on the 26th of December 2003, when I leave
the warmth of Darwin to take up a position as “Plant Inspector”. Plant
Inspector? It’s a strange job title in a land that is barren of all forms of
vegetation apart from a few species of moss and lichen! But as a diesel
mechanic the plant I inspect is not the vegetable kind.
Before work begins, Australian Expeditioners have to go through
extensive training in preparation for the severe winter season. The training
programs cover all facets of survival in the sub zero environs, including
sleeping in an “ice coffin”, a trench hacked out of the snow and ice, in which
you lay in your sleeping bag and “bivvy bag” (a light-weight, wind-resistant
type of tent) to get away from the wind and blinding snow. Survival is the
main thrust of working here in the Antarctic and our experience is not unlike
that of those people who have ventured into the harsh desert country of inland
Australia.
Casey is remote from the outside world. Some 3,800 kilometres from
Perth, WA, at 66 degrees South, it is situated on the coast at the edge of a
dome of ice called Law Dome. The dome rises approximately 1,000 feet into the
sky behind the station. Across the bay, one-and-a-half miles to the north of
Casey, you can see Wilkes, the old American station established here in 1957.
It is now in ruins and mostly covered by ice and snow.
Some of the buildings at Wilkes are still accessible through hatches in
the roof, which open up into a ghostly frozen interior. The ice has built up
here to a level within a metre of the ceiling but it is clear enough to see
through and you can make out the various pieces of equipment that still remain
frozen forever in their silent tomb.
Beyond Wilkes, the horizon is littered with hundreds of icebergs of
various shapes and sizes, many of which are grounded on the Peterson Ice Bank.
The setting sun casts rays of red and golden light across the tops of these
bergs to create an amazing panorama of these silent and beautiful giants. This
is the view from my room looking towards Darwin, to warmth and home.
Along the coast of Antarctica are hills and rocky outcrops as well as
numerous islands along the shore. All of these contribute to a beautiful and
peaceful scene with distant icebergs and never-ending sky. There are contrasts
of colour, easily distinguishable peninsulas of landfall receding into the
dark blue of the ocean, outcrops of windswept rock, barren of any vegetation.
Best of all are the glowing iridescent colours of the sunrise and sunset. This
is picture book Antarctica, abounding with penguins and birds throughout the
summer breeding season, beautiful landscapes in every direction and so
different from the inland.
Halfway through my tour here, I move over to the Air Transport Project
and begin working on the construction of an ice runway, 65 kilometres inland.
It is the nearest suitable place for a runway, which will allow for the rapid
transit of science personnel to and from Antarctica -- but only in the middle
of summer.
To get there, we travel in Caterpillar D-7 bulldozers, as used for all
larger crossings of the ice cap. The bulldozers have been set up especially
for traverse work, with fuel racks opened up to supply more fuel and to give
you a top speed of 12 kph, depending on the conditions. They use aviation-type
kerosene (ATK) with an anti-icing inhibitor that freezes around the minus
67-degree mark.
At an average speed of 8-10 kph, the crossing is slow and tedious with
plenty of noise and rough surfaces. The 65-kilometre journey to the airfield
takes you around 10-12 hours, especially when you are pulling several sleds.
The first sled is filled with drums of fuel, the second is a workshop and
generator van followed by the communications van and sleeping quarters.
Inland Antarctica is forbidding, white and barren. Long flat plains as
far as the eye can see in all directions, windswept snow with hardened patches
of blue ice devoid of vegetation and animals of any description. Everything is
white and grey with patches of blue where the snow has turned to ice. At
times, the definition between ice and sky is difficult to determine; the
horizon blends into the sky and the sky into the horizon.
You come across an occasional bump of snow or lumps of hardened ice
called sastrugi, which reflect an eerie blue glow almost as if they were lit
from inside with a fluorescent light. The reflected sun burns any areas of
exposed skin in a short period of time, which is difficult to comprehend when
the temperature is still below zero.
Distance is impossible to judge. Your eyes are deceived by countless
mirages, small insignificant objects appear huge and miles away in the
distance, yet at other times you are unsure where you are walking and you
stumble and fall into sastrugi, which you are unable to see at your feet.
There are no reference points to help you make your judgment and the
terrain can change from day to day as the fierce winds scour the surface,
moving mountains of snow over a very short period of time. You can wake in the
morning to find your doorway blocked with a wall of snow or a blizzard tail
stretching from a rocky outcrop to form a ridge of hardened snow several
metres high that was not there the day before.
Snowfalls vary from a few millimetres to several metres at any one time.
The snow is continually shifting like the sands of the desert and at times the
intensity of the wind will reduce your visibility to almost zero, when you
can’t even see the ground beneath your feet. It is a place of extreme climate,
harsh winds and blinding snowstorms that may last for days. The inland is a
place where the wind is both lazy and bitter. It can shift a mountain of snow
overnight and bury your vehicle and it can also be deathly quiet with no
movement and nothing to see.
When we head back to Casey for a break, driving is a mammoth effort with
no roads and no landmarks by which to navigate. The horizon is the same in all
directions so your lifeline is your dash-mounted GPS. You are wholly dependent
on the readings from your GPS and bamboo canes set in the ice as markers to
let you know that you are on track. The cane markers have three aluminium beer
cans attached to the centre to allow the radar to pick up a reading in adverse
weather conditions. Vehicles are fitted with navigation radar as well as the
GPS navigation system.
Speed across the ice varies from crawling speed to a fast 25 kilometres
an hour. We travel in a versatile Hagglunds vehicle, which carries four
passengers and drives on all four tracks at the same time, exerting low ground
pressure for travel in soft snow. The ride is rough and you feel as though you
have just completed ten rounds in a heavyweight-boxing tournament at the end
of the day.
A snowstorm approaches across the white desert and my thoughts turn to
the warmth of northern Australia, even the cool nights in the desert south of
the Alice when we thought it was cold. Never in my wildest dreams did I think
I would be standing here in the wild and harsh Antarctic landscape,
experiencing such low temperatures.
In ways the desert is similar -- vast areas of nothing, harsh
temperatures, cruel winds scouring the landscape, moving the surface in an
ever-changing myriad of designs, a place where isolation makes you feel so
insignificant in Nature. Like the desert, the Antarctic is also dangerous and
life threatening and not a place for people who are ill prepared and laugh in
the face of such extremes of climate. This place will kill you through the
sheer extremes of nature, through the biting wind, the loss of visibility, the
lack of recognizable landmarks, and the disorientation.
Both places are vast expanses of nothing, yet in their own way they
exhibit a beauty beyond your imagination and they get into your blood. The
white and red deserts have an awe-inspiring atmosphere that is addictive and
feeds your desire to explore the last untouched areas of the planet.
