The elevation changes of ice sheets have been recognized as an essential climate variable.
Long-term time series of these changes are an important parameter to understand climate …

Abstract Models of the glacial‐isostatic adjustment (GIA) to past ice‐mass changes exhibit
large differences in north‐east Greenland owing to insufficient knowledge about glacial …

The Greenland Ice Sheet is now the largest land ice contributor to global sea level rise,
largely driven by increased surface meltwater runoff from the ablation zone, ie, areas of the …

Abstract The Amundsen Sea (AS) sector in West Antarctica accounts for a significant
proportion of Earth's ice losses and is the largest contributor of Antarctica's mass loss. To …

Abstract The Greenland Ice Sheet contributed 10.6 mm to global sea level rise between
1992 and 2018, and it is projected to be the largest glacial contributor to sea level rise by …

Most of the Greenland and Antarctic ice sheets are covered with firn—the transitional
material between snow and glacial ice. Firn is vital for understanding ice-sheet mass …

Abstract Greenland Ice Sheet surface melting has increased since the 1990s, affecting the
rheology and scattering properties of the near‐surface firn. We combine firn cores and …

Spaceborne radar altimetry over ice sheets has exclusively focused on assessing volume
changes through changes in surface elevation. For use in mass balance calculations, these …

Abstract The Greenland and Antarctic ice sheets are covered in a layer of porous firn.
Knowledge of firn structure improves our understanding of ice sheet mass balance, supra …

Greenland's future contribution to sea-level rise is strongly dependent on the extent to which
dynamic perturbations, originating at the margin, can drive increased ice flow within the ice …
