Radar sounding is a powerful geophysical approach for characterizing the subsurface
conditions of terrestrial and planetary ice masses at local to global scales. As a result, a wide …

Buoyant plumes form when glacial ice melts directly into the ocean or when subglacial
meltwater is discharged to the ocean at depth. They play a key role in regulating heat …

In this study, we achieved magnetic control of reactive scattering in an ultracold mixture of
23Na atoms and 23Na6Li molecules. In most molecular collisions, particles react or are lost …

Subglacial hydrology is a leading control on basal friction and the dynamics of glaciers and
ice sheets. At low discharge, subglacial water flows through high-pressure, sheet-like …

Ice shelves play a vital role in regulating loss of grounded ice and in supplying freshwater to
coastal seas. However, melt variability within ice shelves is poorly constrained and may be …

Increasing melt of ice sheets at their floating or vertical interface with the ocean is a major
driver of marine ice sheet retreat and sea level rise. However, the extent to which warm, salty …

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 …

We present a novel and computationally efficient subglacial hydrological model that
represents in a simplified way both hard-and soft-bed rheologies, as well as an automatic …

Antarctic ice shelves buttress the flow of the ice sheet but are vulnerable to increased basal
melting from contact with a warming ocean and increased mass loss from calving due to …

Ice shelves buttress ice streams and glaciers, slowing the rate at which they flow into the
ocean. When this buttressing is reduced, either through increased melt or calving, the …
