Investigation of the bedrock beneath the glacier by cosmic muon tomography

Glaciers have essentially characterised the shape of the Alps and of Switzerland. Researchers of the University of Bern want to investigate the bedrock of the uppermost part of the Aletsch glacier (Jungfraufirn) with the help of cosmic-ray muon tomography. For this purpose, several cosmic muon detectors, made of emulsion films, were installed along the Jungfrau Railway tunnel. With these detectors, incoming muons are registered. The patterns of the detected muons are then used to map the orientation of the bedrock underneath the glacier in three dimensions.

Swiss consortium participates in the European network for CO2-research

The use of fossil carbon fuel can be seen in the increase of the concentration of carbon dioxide (CO2). The new established science-infrastructure «Integrated Carbon Observation System (ICOS-ERIC)» generates harmonized, highly precise data for the better understanding of the carbon cycle. The Swiss consortium, including research groups from ETH Zurich, Empa, WSL, MeteoSwiss and the Universities Basel and Bern, is an active participant of this infrastructure by measurements at the research station Jungfraujoch.
