NASA’s ICESat-2 satellite recorded the cleaving of a 315-billion-ton iceberg from Amery Ice Shelf in 2019, as well as years of subtle cracking and splitting prior to the calving event.
Climate change is at the center of a remarkable international drilling operation into Antarctica’s Ross Ice Shelf.
The newly digitized data double the timescale of ice-penetrating radar monitoring in some of the fastest changing areas of Antarctica.
Modeling icebergs as Lagrangian elements held together by numerical bonds provides insights into coupled exchanges of heat, freshwater, and momentum between large icebergs and the ocean.
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.
Accurately modeling melt rates in specific ice shelf locations is critical for forecasting how Antarctica’s ice sheet will respond to climate change.
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.
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.
A recent paper in Reviews of Geophysics discusses how ocean tides affect the motion of, and loss of ice from, the Antarctic and Greenland ice sheets.
