The influence of hydrology on the dynamics of land-terminating sectors of the Greenland ice sheet
Coupling between runoff, hydrology, basal motion, and mass loss (“hydrology-dynamics”) is
a critical component of the Greenland Ice Sheet system. Despite considerable research …

Ice-flow perturbation analysis: a method to estimate ice-sheet bed topography and conditions from surface datasets
One of the largest contributors to uncertainty in predictions of sea-level rise from ice-sheet
models is a lack of knowledge about the bed topography beneath ice sheets. Bed …
