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 …

Coupling between runoff, hydrology, basal motion, and mass loss (“hydrology-dynamics”) is
a critical component of the Greenland Ice Sheet system. Despite considerable research …

Atmospheric warming is increasing surface melting across the Antarctic Peninsula, with
unknown impacts upon glacier dynamics at the ice-bed interface. Using high-resolution …

Remote sensing is commonly used to monitor supraglacial lakes on the Greenland Ice
Sheet (GrIS); however, most satellite records must trade off higher spatial resolution for …

Subglacial hydrology plays a key role in many glaciological processes, including ice
dynamics via the modulation of basal sliding. Owing to the lack of an overarching theory …

The flow speed of the Greenland Ice Sheet changes dramatically in inland regions when
surface meltwater drains to the bed. But ice-sheet discharge to the ocean is dominated by …

Detection, attribution and projection of mass loss from the Greenland Ice Sheet has been a
central focus of the glaciological community, with surface meltwater thought to play a key …

Supraglacial lake drainage events influence Greenland Ice Sheet dynamics on hourly to
interannual timescales. However, direct observations are rare, and, to date, no in situ studies …

Supraglacial liquid water at the margins of ice sheets has an important impact on the surface
energy balance and can also influence the ice flow when supraglacial lakes drain to the …

We introduce MPAS-Albany Land Ice (MALI) v6. 0, a new variable-resolution land ice model
that uses unstructured Voronoi grids on a plane or sphere. MALI is built using the Model for …
