Polar Snow and Firn Properties - Examples from a Natural Long -Term-Experiment
Polar snow and firn represents the result of snow metamorphism at very long time scales of many tens of years and in a broad variability of climate conditions. At polar ice sheets the diverse snow types of firn layers and the long term behavior of their microstructure and density with depth and at d...
