Late evening sun over ABN camp

Aurora Basin North, Antarctica

December 2013 - January 2014

Location : Aurora Basin North, Antarctica ; 71°10'S, 111°22' E, altitude 2701 m

Mean annual temperature : -43.5°C

Team members 2013-2014 : Chunlei An (PRIC, CN), Malcolm Arnold (AAD, AU), Jenny Carlisle (AAD, AU), Bloo Campbell (AAD, AU), Jérôme Chappellaz (LGGE, Fr.), Mark Curran (Antarctic CRC, AU), David Etheridge (CSIRO, AU), Tony Fleming (AAD, AU), Mana Inoue (Antarctic CRC, AU), Sharon Labudda (AAD, AU), Joe McConnell (DRI, Reno, USA), Andrew Moy (Antarctic CRC, AU), Meredith Nation (Antarctic CRC, AU), Noel Paten (AAD, AU), Trevor Popp (CIC, DK), Simon Sheldon (CIC, DK), J.P. Steffensen (CIC, DK), Tas van Ommen (Antarctic CRC, AU), Feiteng Wang (PRIC, CN). A team of 6 other persons substituted us in early January (including Olivier Alemany from LGGE).

Activities : The IPEV scientific traverse reached first ABN from Dumont d'Urville, to establish a skyway for the aircrafts. Once the camp setup, we reached ABN by air from Casey station, to conduct three ice core drillings. They reached 103, 115 and 303 m, the latter providing a record of roughly 2000 years. On the 115 m drilling, we performed firn air sampling.

My work in the field : I was in charge of the firn air sampling experiment, together with David Etheridge and Tas van Ommen. I was more specifically in charge of continuous measurements of the sampled gases using a SARA laser spectrometer and a LiCor spectrometer.
