Modelling of the densification of polar firn: characterization of the snow-firn transition

, 1997
International audienceThe transformation of dry snow to firn is described by the transition between densification by deformationless restacking and densification by power-law creep.The observed decrease with temperature of the density at the snow- firn ...

Snow/Firn Densification in Polar Ice Sheets

Snow/Firn Densification in Polar Ice Sheets
A sophisticated physical model of the dry snow/firn densification process in ice sheets is proposed. Macroscopically, snow and firn undergo vertical uniaxial compression with non-zero deviatoric stresses and strain rates. The present mathematical description of densificntion includes dilatancy and "force-chain" effects in snow and develops previous ...
