Pictures of the month 2025

After 15 successful and productive years, Markus Leuenberger will step down as Director of the International Foundation High Altitude Research Stations Jungfraujoch and Gornergrat at the end of January 2025. Eliza Harris will take over his position on February 1, 2025. Picture: HFSJG
Participants of the International Conference on Forecasting, Preparedness, Warning, and Response – organized at the University of Bern from January 28-31, 2025 – visited the High Altitude Research Station Jungfraujoch and enjoyed the interesting tour as well as the splendid view from the terrace of the Sphinx-observatory.

The group of Prof. Stephan Schuster from the Singapore Centre for Environmental Life Sciences Engineering (SCELSE) at Nanyang Technological University, Singapore, during their research campaign at Jungfraujoch. Their research encompasses the analysis of atmospheric biomass and precipitation, including rainwater and snow, providing valuable insights into high-altitude microbial communities, their time-span and special dynamics and their ecological and human health significance. Employing a cutting-edge interdisciplinary approach, the project integrates advanced DNA sequencing, microbiological cultivation, and metagenomics to achieve species-level taxonomic identification of airborne microorganisms.

On March 21, 2025, there was a media conference about the future of the Swiss glaciers at the research station at Jungfraujoch, organized by GLAMOS (Glacier Monitoring Switzerland) and the Swiss Academy of Sciences (SCNAT). Various media representatives listened to the presentation by Dr. Matthias Huss (ETH Zurich), Dr. Martina Barandun (Uni Fribourg) and Dr. Andreas Linsbauer (Uni Zurich)(from right to left in the picture). Picture: HFSJGThe United Nations declared 2025 the International Year of Glaciers’ Preservation. On March 21, 2025 – to mark the first ‘International Glacier Day’ – the SCNAT published a new fact sheet about the Swiss Glaciers.Link to the factsheet: https://scnat.ch/en/uuid/i/5e87b42a-9533-5caa-adc3-f64fd6e038e7-Preserving_glaciers_at_over_3000_metres_through_climate_protection

The Soil Science Group at the Institute of Geography, University of Bern, studies the fate of trace elements from soils to other environmental compartments. One understudied aspect of the biogeochemical cycle of trace elements is their biovolatilisation by microorganisms into the atmosphere. The team has been measuring emissions of arsenic and antimony species from soils for over 15 years now. They started working at the Jungfraujoch to investigate the occurrence of these volatile species of arsenic and antimony in the atmosphere, that is to say in gaseous phase, particulate form on filters and in snow. The goal is to determine whether these species are present in upper layers of the atmosphere and to identify their exact chemical species. These atmospheric species can return to soils and waters through wet and dry deposition, thereby completing their environmental cycle. Thus, the team aims to deepen their understanding of the atmospheric dynamics of arsenic and antimony from the soils to the atmosphere and back. Pictures: HFSJG
A group from the Department of Chemistry, Biochemistry and Pharmaceutical Sciences at the University of Bern visited the Stellarium Gornergrat and were given a guided tour by Dr. Timm Riesen, Director of the Stellarium. Photos: DCBP (left: the participants on the dome railing; right: Timm Riesen explains the various telescopes and instruments).
At the Stellarium Gornergrat, the telescope mirror has recently been cleaned. This is not an easy task – also see the detailed report under the News section – and needs good teamwork. Picture upper left: the mirror cell was detached from the telescope. Picture below: you can clearly see the dirt on the mirror. Picture upper right: cleaning of the mirror. Picture below: the cleaned mirror. Picture bottom right: the successful and content team. Pictures: Stellarium Gornergrat
The Institute of Clinical Pharmacology and Toxicology of the University Medical Center Hamburg-Eppendorf is conducting a two-month study at the research station Jungfraujoch to determine the functional significance of two genes for the response to oxygen deficiency at high altitudes in healthy subjects.

At the end of November, there was the official inauguration of the new Fourier transform infrared spectrometer (FTIR) of the University of Liège at Jungfraujoch. Representatives of the University of Liège – including the Rector Prof. Anne-Sophie Nyssen, MeteoSwiss (which supported the installation of the new FTIR financially in the framework of its contribution to the Global Atmosphere Watch (GAW) and Global Climate Observing System (GCOS) programs), the Belgian Embassy in Switzerland and HFSJG were present at the research station Jungfraujoch, to celebrate the continuation of these important measurements.
