Antarctic circumnavigation - End of the expedition

The Antarctic Circumnavigation Expedition (ACE) reached Cape Town on Sunday, 19 March, completing its three-­month voyage around the great white continent. An EPFL and SLF researcher is leading one of the research projects.


Antarctic research - First independent expedition

Two SLF researchers recently brought home initial results from the SLF's first independent expedition to the Antarctic.


Full-scale avalanche experiment - Largest avalanche in 11 years

A successful full-scale avalanche experiment took place today at the SLF's Vallée de la Sionne avalanche test site in Valais (Arbaz district).


Ice crystals - Orientation in the snowpack

How are crystals oriented in the snowpack? Answers are provided by studies undertaken in the Antarctic snowpack.


Practice meets Science - International course

26 participants from 11 countries take part in the first international snow and avalanche course for safety officers, avalanche forecasters and consulting engineers.


Winter tourims - Less snow, shorter ski season

A new study of the SLF shows bare Alpine slopes could be a much more common sight in the future.


Mountain permafrost - Continued warming trend

Measurements carried out by SLF and its partners in the Swiss permafrost monitoring network (PERMOS) show: soil temperatures at 10 – 20 metres depth were higher than ever last year at many locations. In the long run, a steady warming of the permafrost is expected.


Artificial snowmaking - How much water gets lost?

The SLF is examining how much of the water ejected by snow lances is not transformed into snow on the ground.


Avalanche release - New model

A recently developed model describes the principal factors contributing to the release of a slab avalanche.


Natural hazards - Fatalities have been falling since 1946

Since 1946, events associated with natural hazards have claimed more than 1,000 human lives. Researchers at the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) have now compiled a database of these fatalities to analyse the development of casualty figures over time.
