Summer Relief Expedition
South
African National Antarctic Programme
Ludwig Combrinck and Attie Combrink departed from Cape Town on 4 December 2007, onboard the S.A. Agulhas Voyage 140.
Our first stop-over was at Bouvet Island in the
South Atlantic Ocean, also referred to as “the most remote place on Earth,” to
drop off fellow scientists who would spend the summer on the island, working
with the seal and penguin colonies.
The pack-ice this summer extended approximately 1,000
km from the continent. We encountered
icebergs around Bouvet and travelled in the pack-ice from approximately 60°
South. In the end it took us 26 days to
reach Antarctica, and on some days the ship was completely stuck and we could
make no progress.
Upon entering the Antarctic circle at 66° 33' South,
we newcomers to King Neptune’s kingdom first had to meet his wrath. We were dunked in sea water at –2° Celsius
(this is possible because of the water’s salinity), introduced to the king and
queen who blessed us with their foodstuff, and then got the sweet juice to
swallow. Now we also belong to the
Order of Antarctic Fellows (O.A.F.).
Fortunately, we had many companions on our journey…
birds, seals and a few whales.
Upon reaching the ice shelf, the first task was to
bulldoze a ramp for offloading cargo, after which passengers were flown to the
base.
The South African permanent research base in
Antarctica, SANAE IV (the 4th South African National Antarctic
Expedition base), is located on the Southern Buttress of Vesleskarvet (the
right-hand side of the picture below), a mountain in Western Dronning Maud Land
in the Norwegian Antarctic Territory, 71° 40' South 2° 51' West.
Being located in a desert, i.e. having very little
annual precipitation, requires “smelly duty” where each person gets a turn to
shovel a few tonnes of snow over the course of a day into a snow melter in
order to make water for the base occupants.
The base has an amazing view over the mountains to
the south… this was the view we had from our office / laboratory.
Doing much work in the field, allowed us the
opportunity to travel quite a bit from SANAE IV: we visited Knotten (20 km
northeast), Lorenzenpiggen (7 km south) and Grunehogna (40 km south).
Dr. Ludwig Combrinck
and Dr. Attie Combrink from HartRAO’s Space Geodesy Programme, at 72° South.
Out in the field we installed radar reflectors (for
the South African Hydrographer to calibrate Antarctic coastline maps produced by
radar images taken from satellite) and GPS self-centring plates (to determine
whether the Earth’s crust deforms locally).
Thereafter we surveyed the positions of these new installations with
state-of-the-art GPS equipment.
Travelling to these places required transport in the
form of skidoos or helicopter. We also
had the chance to experiment with more outdated modes of transport.
We also had the opportunity to visit our Norwegian
colleagues at the Troll Base. They use
a Toyota Hilux for transporting VIPs from the airfield, such as the Prime
Minister who visited the previous week to officially inaugurate the new base.
Other work included the measuring of horizon
profiles using a theodolite…
…or measuring atmospheric turbulence by observing
and photographing astronomical sources such as the Moon or Venus.
Ludwig set up a commemorative radio station for
Admiral Byrd (early Antarctic explorer) and made the first AM contacts from
Antarctica in probably 40 years, using his Collins equipment.
Fortunately there is also time for entertainment,
like having a braai…
…or a formal dinner…
…or participating in the sport events (football
while wearing Onitsuka boots, tug-of-war, or snow-boot throw).
As in the past, the Scientist Team won the toughest
battle of all, the tug-of-war. Meet the
champions:
“Windscooping” is an activity well-suited for summer
afternoons or evenings, when the Sun is only a few degrees above the horizon in
the southwest. The activities at the
windscoop include snowboarding, skiing, sliding downhill on a mattress (the
current speed record is 90 km/h) or climbing ice walls with an ice-pick.
So if you can stay as warm as Ludwig with his
Ukrainian rabbit-skin headwear, Antarctica could be the biggest party island
of them all.
