Melting is pervasive along the ice surrounding Antarctica. On the surface of the grounded ice
sheet and floating ice shelves, extensive networks of lakes, streams and rivers both store …

We review the findings of approximately 60 years of in situ and remote sensing studies of
glacier crevasses, as well as the three broad classes of numerical models now employed to …

Seasonal acceleration of the Greenland Ice Sheet is influenced by the dynamic response of
the subglacial hydrologic system to variability in meltwater delivery to the bed, via crevasses …

We present a two‐dimensional Glacier Drainage System model (GlaDS) that couples
distributed and channelized subglacial water flow. Distributed flow occurs through linked …

At a hole in lake ice, a painting from the year 1900 by Finnish artist Pekka Halonen (1865–
1933), who is well known especially of his winter landscapes. In cold regions the normal life …

Recent observations of dynamic water systems beneath the Greenland and Antarctic ice
sheets have sparked renewed interest in modelling subglacial drainage. The foundations of …

Abstract Predictions of the Greenland Ice Sheet's response to climate change are limited in
part by uncertainty in the coupling between meltwater lubrication of the ice-sheet bed and …

Understanding Greenland ice sheet (GrIS) hydrology is essential for evaluating response of
ice dynamics to a warming climate and future contributions to global sea level rise. Recently …

A numerical model is used to calculate how the motion of an idealized ice-sheet margin is
affected by the subglacial drainage of melt water from its surface. The model describes the …

Melt and supraglacial lakes are precursors to ice shelf collapse and subsequent accelerated
ice sheet mass loss. We used data from the Landsat 8 and Sentinel-2 satellites to develop a …
