Antarctica’s Underground

In: Maps Science

5 Dec 2011

Using ice penetrating radar, scientists have mapped out the ground and mountains that lie beneath Antarctica’s ice sheets. The project is interesting because it draws on decades of work from many different teams and datasets, and will help create more accurate models of melt rates.

Did they figure out which ones are the Mountains of Madness? Us Lovecraft fans want to know! :-)

I found this fascinating but poorly described by the BBC article. While the maps presented do a great job of illustrating the peaks and troughs of the landscape, it gives me no reference to what the ice covers up and what it does not.

Are those highest peaks COMPLETELY underneath ice? Are the deepest troughs completely filled in with ice? So to someone standing on the surface Antartica is one giant completely flat plane? I presume it isn’t and would therefore be more fascinated if I could understand where the ice layer resides in reference to these factors.

@ryan: the bbc article states in its 3rd paragraph:
“It is remarkable to think that less than 1% of this rock base projects above the continent’s frozen veil.”

so, yes: those highest peaks are almost completely covered with ice and those throughs are filled with it.

Piris Reis found that 500 years ago, so it’s not a discovery.
