An ancient landscape, believed to be around 34 million years old, has been discovered beneath the East Antarctic Ice Sheet.
The discovery provides new insights into the geological history of Antarctica and the planet's climate history.
The landscape was discovered using ice-penetrating radar technology.
A team of international scientists has discovered an ancient landscape beneath the East Antarctic Ice Sheet. The landscape, which is believed to be around 34 million years old, was found using ice-penetrating radar technology. The radar data revealed a series of valleys and mountains, which are thought to have been carved by an ancient river system. The discovery provides new insights into the geological history of Antarctica and the planet's climate history.
The research team, led by scientists from the University of Texas at Austin, used radar data from the Polar Geospatial Center at the University of Minnesota and the British Antarctic Survey. The data was collected during multiple research flights over the East Antarctic Ice Sheet. The radar technology allowed the scientists to see through the ice and map the topography of the land beneath.
The ancient landscape is believed to have been formed during the Eocene epoch, a period of time when the Earth's climate was much warmer than it is today. The discovery of the ancient river system suggests that the East Antarctic Ice Sheet has been stable for millions of years, which has implications for understanding how it might respond to future climate change.
The findings of the study have been published in the journal Nature. The research is part of an ongoing effort to understand the history and stability of the Antarctic ice sheets, which are a key factor in global sea level rise. The discovery of the ancient landscape adds a new dimension to our understanding of the geological history of Antarctica and the planet's past climate conditions.
