Warm Water Is Rapidly Eroding Antarctica’s Ross Ice Shelf
The underside of the world’s largest ice shelf is melting—by meters per year in some places—because of the seasonal inflow of water heated by the Sun, observations of the White Continent reveal.

Extending the Record of Surface Melt on the Larsen C Ice Shelf
The first use of Advanced Scatterometer radar data to determine melt duration on an Antarctic ice shelf shows the season has decreased by up to 2 days per year during the extended 21st century record.
