DOI: 10.1016/j.quascirev.2017.10.027
Abstract: Abstract The Late Wisconsin Cordilleran Ice Sheet (CIS) of western North America is thought to have reached its maximum extent (∼2.5 × 106 km2) as late at c. 14.5 ka. Most (80%) of the ice sheet's bed consists… read more here.

DOI: 10.1016/j.quascirev.2019.105915
Abstract: Abstract Ice stream evolution is a major uncertainty in projections of the future of the Greenland and Antarctic Ice sheets. Accurate simulation of ice stream evolution requires an understanding of a number of “ingredients” that… read more here.

DOI: 10.1017/jog.2020.44
Abstract: Abstract Streaming ice accounts for a major fraction of global ice flux, yet we cannot yet fully explain the dominant controls on its kinematics. In this contribution, we use an anisotropic full-Stokes thermomechanical flow solver… read more here.

DOI: 10.1111/bor.12512
Abstract: The Polish sector of the last Scandinavian Ice Sheet is a key area for studying ice‐sheet drainage and decay from its local Last Glacial Maximum (LGM) extent, as it is located at the terrestrial terminus… read more here.
