Is There Land Under Antarctica's Ice?

While the Antarctic ice sheet is several kilometers thick, geophysical data (seismic surveys, ice-penetrating radar, gravity measurements, satellite imagery) suggest the presence of sub-ice terrain, including basins, ridges, and geological structures. However, as of the latest research, no definitive, confirmed landmasses have been directly observed. The hidden bedrock topography influences ice flow and is an active area of scientific investigation.
