Changes in the Velocity Structure of the Greenland Ice Sheet
TLDR
Using satellite radar interferometry observations of Greenland, widespread glacier acceleration below 66° north between 1996 and 2000, which rapidly expanded to 70° north in 2005, and as more glaciers accelerate farther north, the contribution of Greenland to sea-level rise will continue to increase.
Ice-Shelf Melting Around Antarctica
TLDR
Detailed glaciological estimates of ice-shelf melting around the entire continent of Antarctica show that basal melting accounts for as much mass loss as does calving, making ice- shelf melting the largest ablation process in Antarctica.
Bedmap2: improved ice bed, surface and thickness datasets for Antarctica
We present Bedmap2, a new suite of gridded products describing surface elevation, ice-thickness and the seafloor and subglacial bed elevation of the Antarctic south of 60° S. We derived these
Ice Flow of the Antarctic Ice Sheet
TLDR
A reference, comprehensive, high-resolution, digital mosaic of ice motion in Antarctica assembled from multiple satellite interferometric synthetic-aperture radar data acquired during the International Polar Year 2007 to 2009 reveals widespread, patterned, enhanced flow with tributary glaciers reaching hundreds to thousands of kilometers inland over the entire continent.
Acceleration of the contribution of the Greenland and Antarctic ice sheets to sea level rise
Ice sheet mass balance estimates have improved substantially in recent years using a variety of techniques, over different time periods, and at various levels of spatial detail. Considerable
Recent Antarctic ice mass loss from radar interferometry and regional climate modelling
Observed estimates of ice losses in Antarctica combined with regional modelling of ice accumulation in the interior suggest that East Antarctica is close to a balanced mass budget, but large losses
A Reconciled Estimate of Ice-Sheet Mass Balance
TLDR
There is good agreement between different satellite methods—especially in Greenland and West Antarctica—and that combining satellite data sets leads to greater certainty, and the mass balance of Earth’s polar ice sheets is estimated by combining the results of existing independent techniques.

A new bed elevation dataset for Greenland
Abstract. We present a new bed elevation dataset for Greenland derived from a combination of multiple airborne ice thickness surveys undertaken between the 1970s and 2012. Around 420 000 line
Contribution of the Patagonia Icefields of South America to Sea Level Rise
Digital elevation models of the Northern and Southern Patagonia Icefields of South America generated from the 2000 Shuttle Radar Topography Mission were compared with earlier cartography to estimate
