TURKU UNIVERSITY DEPARTMENT OF GEOGRAPHY PUBLICATIONS B Nr 4Radio-echo sounding – AustriaRadio-echo sounding of Hintereisferner was accomplished in August 2001. This was done inaddition to profiles measured since 1982. At one of the profile lines known as Line 6(Figure18), ice thickness has decreased by approximately 60 m since 1982. The ice in thedeepest part of Hintereisferner is over 200 m thick (Figure 20), although most ofHintereisferner has an ice thickness of about 100 m (Figure 19).110010501000950900850800750700650600550500450400350300250200150100500Figure 16.
