Ice is one of the most transparent natural minerals for human eyes. For observers of snow, this poses many challenges. Because the snow appears to us more or less uniformly white, we often have to use destructive methods to get an approximate view of its structure. In this talk, Martin shows how computed tomography and near-infrared photography improve our ability to see “the invisible snow”.

Martin Schneebeli is a snow researcher for 30 years and still fascinated by the changing nature of snow. He works at the WSL Institute for Snow and Avalanche Research SLF in Davos, Switzerland. His main interest is in the structure of snow, and understanding its structure. With his research group, he developed new methods to measure the structure.
