Caption: Antarctic bedrock. Computer model of the bedrock beneath the Antarctic ice sheet compiled from millions of measurements, taken over decades, from satellites, aircraft and surface surveys. Understanding the bedrock is crucial to understanding the ice sheet above it and how it changes, including how its melting could contribute to global sea level rises. This model, known as Bedmap2, was compiled by the British Antarctic Survey.
