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 …

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 …

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 …

Thermally incised meltwater channels that flow each summer across melt-prone surfaces of
the Greenland ice sheet have received little direct study. We use high-resolution WorldView …

The impact of increasing summer melt on the dynamics and stability of the Greenland Ice
Sheet is not fully understood. Mounting evidence suggests seasonal evolution of subglacial …

Surface meltwater reaching the bed of the Greenland ice sheet imparts a fundamental
control on basal motion. Sliding speed depends on ice/bed coupling, dictated by the …

Meltwater runoff from the Greenland ice sheet surface influences surface mass balance
(SMB), ice dynamics, and global sea level rise, but is estimated with climate models and …

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

The spatiotemporal distribution and variability of surface water remained poorly known at the
pan-Greenland scale, and its dominant features (supraglacial rivers, lakes, and water-filled …

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 …
