Snow/Firn Densification in Polar Ice Sheets

Snow/Firn Densification in Polar Ice Sheets
III. Firn densification, close-off and chronology 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.
