Dec. 12 (UPI) --Scientists have successfully mapped the topography of the land beneath Antarctica's ice sheet at high resolution by combining radar observations with ice volume and flow velocity data.

As global temperatures rise, Antarctic ice will gradually start to loosen and fall into the ocean. With Bedmap3 as a guide, researchers can determine which parts of the sheet are likely to fall ...

Scientists have revealed the most detailed map of the land beneath the massive ice sheets of Antarctica – a map that offers significant insight into how the continent will respond to climate change ...

The Antarctic ice sheet, which covers 98% of the continent, averages around 1.2 miles in thickness, with its thickest point reaching nearly 3 miles, the Australian Antarctic Program reports.

Using a recent map of surface meltwater ponds on the East Antarctic Ice Sheet, which reaches lower (warmer) latitudes, the researchers find that only 0.6 percent of the ice shelf area there is ...

Containing around 750,000 cubic miles of ice – enough to fill Wembley Stadium nearly 3 billion times – the West Antarctic Ice Sheet is a rich reservoir of precious frozen freshwater.

Parts of the West Antarctic ice sheet are rapidly losing ice into the sea. Red areas have lost significant amounts of ice since 2010. Blue areas have gained ice.

Right now, she said the land-based ice sheets in Antarctica are not melting that much compared to the floating ice shelves, or compared to Greenland, but that is likely to change with more warming.

Ocean tides can trigger city-sized icebergs to break off from Antarctic ice shelves, scientists said on Thursday, offering a ...

Naturally, the land beneath that massive sheet of ice is of great interest to the scientific community, both for its own sake and for the data we could glean about climate change and ocean levels.
