Ice sheets are expected to shrink in size as the world warms, which in turn will raise sea
level. The West Antarctic ice sheet is of particular concern, because it was probably much …

Locally grounded features in ice shelves, called ice rises and rumples, play a key role
buttressing discharge from the Antarctic Ice Sheet and regulating its contribution to sea level …

Abstract Quantarctica (https://www. npolar. no/quantarctica) is a geospatial data package,
analysis environment, and visualization platform for the Antarctic Continent, Southern Ocean …

Government policies currently commit us to surface warming of three to four degrees Celsius
above pre-industrial levels by 2100, which will lead to enhanced ice-sheet melt. Ice-sheet …

Ice discharge from large ice sheets plays a direct role in determining rates of sea-level rise.
We map present-day Antarctic-wide surface velocities using Landsat 7 and 8 imagery …

The floating ice shelves surrounding the Antarctic Ice Sheet restrain the grounded ice-sheet
flow. Thinning of an ice shelf reduces this effect, leading to an increase in ice discharge to …

We combined an ensemble of satellite altimetry, interferometry, and gravimetry data sets
using common geographical regions, time intervals, and models of surface mass balance …

The floating ice shelves along the seaboard of the Antarctic ice sheet restrain the outflow of
upstream grounded ice,. Removal of these ice shelves, as shown by past ice-shelf recession …

Abstract Changes in accumulated snowfall over the Antarctic Ice Sheet have an immediate
and time-delayed impact on global mean sea level. The immediate impact is due to the …

Atmospheric warming threatens to accelerate the retreat of the Antarctic Ice Sheet by
increasing surface melting and facilitating 'hydrofracturing',,,,,–, where meltwater flows into …
