Grounding-line dynamics

What governs the transition from grounded ice sheets to floating ice shelves? How does the action of tides influence the basal sliding of ice?

Hydrology of deforming sediments

How does water pressure influence the dynamics of subglacial sediment? To what extent does sediment deformation feed back into water pressure?

Subglacial landforms

What can landforms in formerly glaciated areas tell us about the dynamics of past and present ice sheets?
