BedMachine Antarctica is a project to map the sub-surface landmass below the ice of Antarctica using data from radar depth sounding and ice shelf bathymetry methods and computer analysis of that data based on the conservation of mass.[1][2]
The project is uses data from 19 research institutes.[1] It is led by the University of California, Irvine.[2]
It has revealed that the Antarctic bedrock is the deepest natural location on land (or at least not under liquid water) worldwide, with the bedrock being 3,500 m (11,500 ft) below sea level.[3][4]
