In the last century and a half, average summer temperatures have slowly been rising worldwide. The most observable consequence of this is the change in glacier sizes. For monitoring glacier area and ...volume, various measuring techniques exist-from measurements with a measuring tape and geodetic measurements to remote sensing and photogrammetry. A comparison of different measuring techniques on two Slovenian glaciers (the Triglav and Skuta glaciers) and two Austrian glaciers (the Gossnitzkees and Hornkees glaciers) is made. A long-term glacial retreat trend is presented for the Gossnitzkees, Hornkees, and Triglav glaciers because these glaciers can be monitored throughout the entire twentieth century by means of archival data. Despite their different sizes, the annual trend of glacial retreat was approximately the same in the period between 1929 and 2006.
The Triglav Glacier lies on the southeast edge of the Alps, in the Julian Alps below Mount Triglav, Slovenia’s highest peak. Its upper edge lies at 2,500 m. The glacier has been regularly measured, ...observed, and studied since 1946 by the Anton Melik Geographical Institute at ZRC SAZU. When measurements began it covered 14.4 ha, but today it covers less than half a hectare. The glacier no longer has all glacial features. Thus one may only speak of a glacier because of its past, when it clearly had the basic features of an alpine glacier. Analysis of the geomorphic forms of the Triglav Mountains allows reconstruction of past glaciation. Moraine deposits above the upper edge of Mount Triglav’s North Wall indicate the glacier’s extent during the Little Ice Age. When this ended in the nineteenth century, visits to the Triglav Mountains started increasing, and so there are many written and pictorial sources available from this time.
Geografski inštitut Antona Melika ZRC SAZU že več kot šest desetletij opravlja redne meritve Triglavskega ledenika in ledenika pod Skuto. Oba ledenika se v zadnjem desetletju in pol intenzivno ...krčita. S krčenjem ledenika pod Skuto prihaja vse bolj do izraza pomen njegove senčne lege na vznožju okoliških ostenij. S primerjavo dinamike krčenja ledenika in izbranih meteoroloških kazalcev primerljivih opazovalnih postaj izpostavljamo pomen in stopnjo vplivanja podnebnih sprememb na ta, najbolj jugovzhodno ležeč ledenik na območju Alp.
