Ecology
If you ask anyone to imagine Antarctica, most people will immediately think of a huge layer of ice.
Antarctica is the largest ice sheet in the world, but what lies beneath it?
NASA scientists have shown the surface of Antarctica, which has been hidden under a thick layer of ice for more than 30 million years.
In a project called BedMap2, researchers calculated the total amount of ice in Antarctica to predict future sea level rise.
To do this, they needed to know its underlying topography, including broad valleys and hidden mountain ranges.

New map of Antarctica
Some of the most impressive discoveries in Antarctica were the deepest point on all continents, the valley under the Bird Glacier, which is 2,780 meters below sea level. Scientists also obtained the first detailed images of the Gamburtsev Mountains, which are under a 1.6-kilometer layer of ice.
The new map is based on the level of surface elevation, ice thickness and base topography, which were taken using ground, aerial and satellite surveys.

Scientists also used radars, sound waves, and electromagnetic tools to map the map.
