NASA's Icebridge mission has released new detailed maps which give a much clearer picture of what Antarctica looks like from the ice surface down to the bedrock below.
The first NASA image below shows the latest analysis of the Antarctic Ice Sheet.
The second NASA image shows the underlying bedrock of Antarctica.
If you go directly to the NASA story you can use a slider to compare the two images above.
NASA also posted a nice video on the subject. Video courtesy of YouTube.
The British Antarctic Survey (BAS), which led the effort put together decades of geophysical measurements from NASA's ICESat satellite and ice thickness data from airborne flights by Operation Icebridge.
