Have you ever wondered what’s beneath all of that ice on Antarctica’s massive surface? Thanks to NASA, now we know. The space agency recently released a video that shows results of what’s called Bedmap2, the most precise look we’ve ever had at the landmass of Antarctica. Take a look at the video below for more:
It was assembled by the British Antarctic Survey from millions of datasets, lots of which were supplied by NASA’s own Operation IceBridge. Operation IceBridge uses airplanes, rather than satellites, to monitor changes in polar ice, using a DC-8 and several other general-purpose airplanes. Laser altimeters, RADAR, and some odder tools like a gravimeter and magnetometer help NASA figure out what the land of Antarctica actually looks like.
