More than a thousand satellite image scenes captured of Antarctica during a seven year observation have created this visually stunning true-color Landsat Image Mosaic of Antarctica (LIMA) by NASA, USGS, National Science Foundation (NSF) and British Antarctic Survey (BAS). The virtually cloudless satellite view of Antarctica’s frozen landscape provides much greater detail for the entire continent than ever before.

It is a continent almost entirely buried by snow and ice. It is so hostile and remote that it has no permanent residents. Surrounded by the Southern Ocean, Antarctica covers nearly 9% of the Earth’s land, and is 25% bigger than Europe, making it the fifth largest continent. It is also the least polluted of all the continents.

About 99% of Antarctica is covered with a vast ice sheet. It is the largest single mass of ice on Earth and is bigger than the whole of Europe. At least 3 million years old (and possibly as much as 30 million years old in places), the ice sheet averages 2,450 metres deep and holds about 70% of the world’s fresh water. With such a thick layer of ice, Antarctica is the highest of all the continents. The average altitude is about 2,300 metres above sea level, although in places, the bottom of the ice can be as much as 3,000m below sea level. If they weren’t filled with ice, large parts of Antarctica would be under the sea. Vinson Massif is Antarctica’s highest point, rising to a height of 4,897 metres.
