Keywords:Numerical ice-sheet model

Ice divides are important locations for deep drilling on ice-sheets.
Precise computation around a divide requires spatially very high
resolution due to the characteristics of ice-flow around the divide.
In addition, ice flow pattern is significantly different between an
ice divide and the other areas: the flow around the divide requires
more stress terms to compute than the other area, which is still a
challenging topic due to its heavy cost of computation.
This study presents a recent development of Ice sheet model for
Integrated Earth system Studies (IcIES) in particular, for improvement
and inclusion of higher-order mechanics.
