Firn densification
Firn densification is the process by which freshly fallen snow gradually transforms into glacier ice. As snow accumulates, the increasing weight of overlying layers compresses the snowpack, causing …

Modeling enhanced firn densification due to strain softening
Ice becomes more less viscous when it is being strained. It is a power law fluid. Therefore firn densifies faster in shear margins. In this paper we show how existing firn densification models can be …
