Exploring the Hidden World Beneath Antarctica's Ice.

NASA's Bedmap2, a detailed topographical model of the bedrock landscape underneath icy Antarctica, created using radar technology and detailed data collection of 25 million measurements, provides insight into a changing world and helps scientists understand how melting ice would flow toward the sea. The shape of the rock bed is particularly important for calculating how climate change will impact Antarctica and the world, as 6.4 million cubic miles of ice could create a 190-foot sea-level rise. Researchers are already at work on Bedmap3 to help further understand our coldest continent in a changing world.
