2008 glaciological
Survey
ANALYSIS OF VARIATIONS
This chapter presents data and information collected during the 2008 surveys. The dynamic
phase of each glacier is evaluated on the basis of the last available survey.
Variations versus 2007
All 47 glaciers, when compared with their 2007 data, are in a shrinking phase, with a net prevalence
(80,8%) of strong and moderate decrements. The tendency of the last years is confirmed
and 2008 is the 4th consecutive year in which 100% of sampled glaciers were reported in a
decrement phase when compared against their previous survey.
The statistical analysis highlights the negative peak of the Ortles–Cevedale Sector, with 4 strong
decrements and 7 moderate decrements.
