APECS OCEANIA IN ANTARCTICA - FINAL BLOG
On Wednesday 15th of
January most of the team left the Aurora Basin camp, with 11 of us heading back to
Casey Station. We packed most of the scientific equipment before we left
but there are plenty more things to pack, such as polar pyramid tents, the
processing tent, and the kitchen tent. The four last people staying at the
camp – Sharon, Mark, Jason and Bloo – will deal with this stuff.
It was an adventurous
trip back to Casey. Eleven of us were spread across two flights in the
Basler and the twin otter. I was in the twin otter. When we took off, I looked
at the Aurora Basin camp from the window. Many memories crossed my mind. It was
a fantastic three weeks. The flight was nice and warm. We saw a round rainbow
with a plane shadow in its centre. The Basler flew with the boxed ice cores so
they couldn’t turn on the heater. They had a freezing two hour flight.
We saw Casey station
clearly from the air. But we couldn’t land on the skiway because of fog. This
is Antarctica; how rapidly the weather changes, how different the weather is
even at a close distance! So the twin otter landed on Mitchell Peninsula
skiway, and the Basler landed on Wilkins runway.
There was a hagglund
waiting for us. We jumped on it and half an hour later we were at Casey. We arrived
at Casey at 11 pm and the chef kindly made us some sandwiches. We had a nice
warm shower, a proper toilet, and a warm bed after a few weeks in field.
Unfortunately for the Basler people, they took more time to land at Wilkins and
they had to stay overnight.
Now I’m sitting in a
corner in Casey station, thinking of the rest of the people at Aurora Basin;
Sharon, Mark, Jason and Bloo. I hope they make it back by Australia day.
I’d like to say a big
thank you to all members up in the field, Mark, Sharon, Tas, Noel, Malcolm,
Simon, Trevor, Jerome, David, Chunlei, JP, Andrew, Meredith, Jenny, Tonny, Joe,
Wang, Bloo, Jason, Olivia, Nerilie, Holly, Chris, Olivier and Tessa; all the
people who supported us from Casey, Kingston, Hobart and all over the world; and
all friends and families back home. Thank you very much for your support.
Without your support, we couldn’t achieve our goals. I had an amazing, awesome,
wonderful time at Aurora Basin. This experience is priceless and cannot be
exchanged with anything else. And personally, a special thank you to Mark. I am
very happy that I am your student.

m four-inch main core (drilled by Simon and Trevor using the Danish Hans
Tausen drill system, dry head to 132 m, reamed, wet drilling (Estisol)
from 132 m; logged by Mark and Meredith, with a cameo appearance by Jen.
- 116
m three-inch shallow core (drilled primarily by Tas, with a few metres by
Mark and Meredith using the Australian Eclipse drill system, and some
expert advice from Trevor; logged by Tas, David, Jerome, Chunlei, Mark,
Meredith and Nerilie.
- 103
m four-inch shallow core (drilled primarily by Olivier, with help from
Jason and Nerilie, using a combination drill of French and Danish
components; logged primarily by Nerilie. Chips from each drill run were
collected for Chunlei.
- Firn
air pumping, sampling and insitu SARA (CH4) and LICOR (CO2)
analysis, in the three inch eclipse borehole by David and Jerome.
- Drilling
three 10 m Kovacs ice cores (for overlap with the main cores). Captained
by Joe with Wang and Mana.
- 2.5
m snowpit dug under difficult weather conditions and sampled for 10
different parameters, led by Holly with the team Olivia, Chris and Mana. A
second pit was dug to allow backlit stratigraphy (Meredith, Olivia, and
Holly).
- Automatic
Weather Station, erected primarily by Meredith, with assistance from a
number of people.
- All
sites were located using accurate GPS by Jason. GPS base station erected
by Andrew and Tas.
- Core
processing equipment setup by JP, Joe, Wang and Mana (including ECM,
horizontal bandsaw, vertical bandsaw, laminar flow bench).
- Core
density measured on main core by JP, and the processing team (Olivia,
Mana, Chris and Holly), and on the four inch shallow core by Nerilie and
Jason.
- Cores
processed to 80 m led by Olivia and her team Mana, Chris and Holly,
including all 'pie' subsampling, ECM, stratigraphy, AAD trace chemistry
sticks scrapped, melted and refrozen, and Picarro samples prepared for 20
cm resolution stable isotopes.
- Picarro
setup by Andrew, and samples analysed by Andrew, Holly and Olivia, with
expert advice from Olivia and Trevor.
I’d like to finish my
blog with some words from Jerome (actually from his wife). Even while he
had a hard time dealing with the problem of his precious machine SARA, he never
got upset. He was always calm and smiling and he told us these words,
which made our day: 'Do your best and always remember that life is beautiful'.
