In ice stream shear margins ice is commonly at its melting temperature at depth and coexists with liquid water at crystal boundaries. Accurately model...

A major source of ice loss on ice sheets is due to fracture related processes leading to ice calving or destabilization through crevasse formation. A ...

Ice-infiltrated sediment, or frozen fringe, is commonly found adhered to the base of glaciers. Recent experiments using a cryogenic ring shear device ...

Subglacial hydrology plays a major role in determining the flow of ice streams over deformable tills, propelling the overlying ice through a variety o...

The relationship between ice speed and basal traction, known as the sliding law, remains a significant source of uncertainty in modeling glacier dynam...

Effective stress in subglacial till (ice overburden minus pore water pressure) is the primary control on bed strength for soft-bedded glaciers and ice...

The coasts of the North American Great Lakes are constantly shaped by waves that begin to interact with the lakebed as they approach the shoreline. Up...

Coastal flooding by overwash causes loss of life, damage to infrastructure, and is mitigated by natural barriers like dunes. Overwash occurs when tota...
