Thickness of glaciers in the federal geoportal

01.07.2021 | ETHZ, GLAMOS

Glacier Monitoring Switzerland (GLAMOS) aims to document glacier changes in Switzerland in the long term. The Laboratory of Hydraulics, Hydrology and Glaciology (VAW) and other GLAMOS institutions systematically collect data not only on development of surface area and volume, but also on snow accumulation, melting of ice, glacier flow and ice temperatures.

Determining the ice thickness and estimating the total ice volume in the Swiss Alps are based on georadar measurements combined with glaciological calculation methods. From the ice thickness measurements available up to 2020 and the knowledge of the glacier areas and surface topography, it was finally possible to determine the distribution of the ice thickness of all glaciers nationwide, which is now presented in the geoportal. In addition, the results allowed the topography of the glacier beds to be derived, and the total ice volume in the Swiss Alps for the year 2020 was determined to be 52.9 ± 2.7 km3.
