Colle Gnifetti perforation by ALPCLIM project in 2003. Two ice core were taken from Colle Gnifetti. Ice cores reached a deep of 82m and 81m. The overarching scientific objective of ALPCLIM was aimed at the exploitation of ALPCLIM glaciers for climate related records. These concerns the archived history of isotope temperature, atmospheric trace constituents as well as the englacial temperature distribution. Different to the vast polar ice sheets, there is a primary need for small scale Alpine glacier archives to evaluate and validate such proxy records in view of their hitherto unknown reliability, spatio-temporal significance and, most important, in view of their underlying net atmospheric signals.
