Adelie Land
Primary CryoNet Station Information

The GLACIOCLIM observatory is a French initiative to monitor the mass balance of glaciers in different climate. This represents the Antarctic component, which covers Adelie Land and Dome C. Data are availeble from Cap Prudhomme (CP, 66.7°S, 139.9°E, 30 m above sea level) and Dome C (-75.1°S, 123.3E, 3233 m asl). CP hosts a summer station at the departure point of the logistical traverse between the coast and the French-Italian Concordia station located 1,100 km inland, on the plateau.
The SMB of Antarctica is the net result of precipitation and surface ablation terms like evaporation/sublimation, melt and run-off, and blowing snow. Here the SMB data are obtained thanks to stake networks and snow density measurements in the first 2.5m of snow or deeper. Measurement protocols and accuracy are described in detail in Eisen et al. (2008)

SMB values (stake height and density measurements) are available since 2004:
1. A 50-stake network is measured monthly (when measrements are possible) in a blue ice area close to CP (Favier et al., 2011).
2. along a 156-km stake-line (91 stakes) from 30m asl to 1820 m asl (Agosta et al., 2012)
3. Measurements at Dôme C (Libois et al., 2014)
