Povzetek

Različne geodetske in lidarske izmere velikosti Triglavskega ledenika omogočajo, poleg preučevanja sprememb njegove površine, tudi preučevanje sprememb debeline in prostornine. Poznavanje teh sprememb omogoča tudi izračun geodetske masne bilance ledenika. Za ugotavljanje sprememb debeline in prostornine, smo uporabili meritve površine ledenika v letih 1952, 1975, 1992 ter meritve med letoma 1999 in 2016. Povprečna debelina ledenika se je zmanjšala iz 39,2m leta 1952 na 2,45m leta 2012. Največja debelina pa se je zmanjšala iz 48,3m leta 1952 na 5,2m leta 2007. Letno specifično masno bilanco smo ugotavljali za območje velikosti 1,0 ha, ki ga je ledenik pokrival leta 2016. Povprečna specifična masna bilanca v celotnem obdobju 1952–2016 je bila −0,45m w.e.a⁻¹ (metri vodnega ekvivalenta na leto).
