WELCOME to Sagax Expedition
What Will We Do?
•Estimate altitude of snow line in region
–GPS + photos
•To study the glacier mass balance, a network of ablation stakes has been installed in 2007 and 2008 using a drill machine. Stakes are 8-10m long (4 or 5 2-m bamboo pieces linked with a metallic wire).
•Measure emergence of stakes on glaciers:
–year of stakes installation
–measure height of snow on top of ice
–measure emerged portion of stakes
–GPS localization of stakes
