In the last decades Alpine glaciers have been loosing mass in an unprecedented speed. Both in scientific literature and the media mass changes of glaciers are often used to visualize climate change. However, quantitave information of the actual mass changes of certain glaciers is not availalbe before the processing of annual measurements during late summer.
The aim of Glacio-Live is to reduce this deficit of information by installing a widely automatic glacier measurement system, which is able to measure and calculate the glacier mass changes on a daily or hourly basis and present the results on the web to a broader public.
The development of this near real-time glacier information system involves the following steps:
To make the data from the stations on the glaciers available in real-time, students from TGM will develop a peripheral wireless data network, which shall be able to operate under the harsh climatic conditions of an alpine environment.
Researchers from ZAMG will develop a data assimilation procedure, which will incorporate data from automatic kameras and meteorological and glaciological stations into a glacioclimatological model, that is used to calculate the acutal rate of mass change of the glaciers. In a final step, students of TGM will develop a website, where the actual state of the glacier will be presented to a broader public.
On the long run, the wireless data network that has been tested on Alpine glaciers within this research project will be installed on glaciers in the Arctic (e.g. on Freya Glacier in Northeast-Greenland, which is regularly measured by ZAMG), where the potential savings will be even higher due to the large distances and high travel costs.
This research project is funded by the Austrian Federal Ministery of Science, Research and Economy within the research programme Sparkling Science.
Development of a near real-time information system of the current state of mass change of Austria´s biggest glacier Pasterze and small glaciers around Sonnblick Observatory.
Development of a peripheral wireless data network, which is able to operate on glaciers in close cooperation with students of TGM Wien.
Installation of all necessary automatic sensors on the glacier to measure the actual mass balance of the glacier in near real time.
Development of a model to transfer this few point measurements to a glacier-wide mass balance value and present the model output on a website.
