Results from a rheological model based on the composite flow law of Goldsby and Kohlstedt (1997, 2001) applied to mean grain size and grain size distributions in the North Greenland Eemian Ice Drilling (NEEM) deep ice core predict that grain-size-sensitive flow produces almost all of the deformation...
