Revealing Detailed Subsurface Topography under Antarctica's Ice

The Discovery: British Antarctic Survey, along with international scientists, has unveiled Bedmap3, the most detailed map of Antarctica's subglacial landscape. This map is the result of 82 million data points collected over 60 years from planes, satellites, and ships. Significance: Bedmap3 showcases an unprecedented ice thickness of 4,757 meters in Wilkes Land. This data is essential for gaining insights into Antarctica's susceptibility to climate change and predicting future ice melt patterns.
