Antarctica isn’t a floating chunk of ice like the Arctic. Beneath its frozen surface sits a solid continent of mountains, rocky terrain, and gold-spewing volcanoes. This hidden world has now been revealed in stunning detail thanks to a groundbreaking map developed by international scientists led by the British Antarctic Survey (BAS).

A new detailed map of Antarctica is set to significantly improve predictions of how ice flows and melts in response to climate change,  say the scientists behind the project.  The map, called Bedmap3,

Bedmap3 is the most fine-grain map to date of the landscape beneath Antarctica's ice. Scientists created it using more than 60 years' worth of data from satellites, ships and dog-drawn sleds.
