The British Antarctic Survey has produced the sharpest image yet of Antarctica’s rugged topography. And as you can clearly see, without its mile-thick layer of ice, the polar continent would be an incredibly mountainous terrain, indeed.
In conjunction with NASA’s IceBridge mission, the BAS compiled this map by drawing upon millions of new measurements of the continent’s surface elevation, ice thickness, and bedrock topography. Called Bedmap2, it's a significant improvement on the previous collection of Antarctic data (go here to compare the two datasets by using a slider to switch between them).
Back in March, the BAS released this topographic color-schemed Bedmap2 image of Antarctica:
