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.

Humming Ice Shelf Changes Its Seismic Tune with the Weather
Seismic waves resonating within the upper layers of the Ross ice shelf could help scientists monitor the Antarctic melt season and understand factors that could lead to sudden ice shelf collapse.
