Length changes of Austrian glaciers 1970 - 2018
The Austrian Alpine Club (Österreichischer Alpenverein) has been coordinating annual measurements of length and surface changes of more than 100 Austrian glaciers for several decades. Besides some glacier inventories, this dataset - a product of voluntary work of many people - represents one of the most comprehensive datasets on Austrian glaciers. The measurements are compiled in the annual glacier reports published by the Austrian Alpine Club.
Based on these data, you can display the development of selected glaciers or glacierized mountain ranges. The diagrams are updated at regular intervals. A major upgrade, including data back to the late 19th Century, is currently in progress, implemented as a master thesis at the University of Graz. Please feel free to use the diagrams under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License.

Time lapse video and images of glacier evolution
This time-lapse video illustrates the evolution of the tongue of Gepatschferner, Kaunertal, Tyrol, Austria, in summer 2020 and 2021, captured with an automatic camera. One image per day was used to create the time-lapse video, excluding days with adverse weather.
The camera was purchased through funds of the University of Graz, Austria, and installed and managed by Martin Mergili (University of Graz) and Stefan Haselberger (University of Vienna) within the frame of the EU-funded project PHUSICOS. The time-lapse video was created by Martin Mergili.
