The Dome C Antarctica ice core is a 906 meter core that spans approximately 32,000 years. It was a thermally drilled core 
and was retrieved during the 1977-78 Antarctic field season as part of the International Antarctic Glaciological project. 
Dome C is located at 74 deg. 39 min. S; 124 deg. 10 min E. at an elevation of 3,240 meters. The mean annual air temperature 
at the site is -53.5 degrees C. The Dome C data set includes isotope and depth age data, plus CO2 and CH4 data published 
in 2001 by Monnin et al. An excellent reference for this core is:
