The object

In every edition of WSL's magazine DIAGONAL we present an instrument, a tool, a machine - in short an object. Apart from the presentation in the magazine, there is always a video clip of the object.

June 2017: The SnowMicroPen

The SnowMicroPen (SMP) is an electronic probe developed by the SLF. It measures the hardness of individual snow layers with extreme accuracy. It delivers high-resolution data about the type of snow, its density, properties of weak layers and layer interfaces.

November 2016: The seed kilning barrel

WSL harvests and kilns forest seed material, and operates the national seed agency, which offers seed material to forestry enterprises and tree nurseries. In a refrigerated storage room, WSL stores up to 60-year-old Norway spurce seeds from a variety of origins, as well as seed material from a further 50 tree species and shrubs.

June 2016: The Shear Apparatus

Before a slab avalanche occurs, small cracks and friction between the snow grains generate noise. The shear apparatus allows researchers in the lab to investigate the fracture process and the acoustic signals.
