Merjenje malih alpskih ledenikov: primeri iz Slovenije in Avstrije ; Measurements of small alpine glaciers: examples from Slovenia and Austria

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 twoSlovenian 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 monitoredthroughout 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 ; V zadnjem stoletju in pol se globalne povpre ne letne temperature stalno dvigajo. Ena od vidnih posledic tega je spreminjanje velikosti ledenikov. Za spremljanje povr inskih in prostorninskih sprememb ledenikov obstajajo tevilne metode, od meritev z merskim trakom, klasi nih geodetskih izmer do daljinskega zaznavanja in fotogrametrije. Uporaba nekaterih je predstavljena na dveh slovenskih (Triglavski ledenik, Ledenik pod Skuto) in dveh avstrijskih ledenikih (Gossnitzkees in Hornkees). Predstavljen je tudi dolgoro en trend zmanj evanja ledenikov Gossnitzkees, Hornkees in Triglavskega ledenika, ki ga na podlagi razli nih arhivskih podatkov lahkospremljamo e od za etka 20. stoletja. eprav so obravnavani ledeniki razli no veliki, izkazujejo primerljiv letni trend zmanj evanja v obdobju med letoma 1929 in 2006.
