An ancient landscape hidden under the East Antarctic ice sheet for at least 14 million years has been revealed with the help of satellite data and planes equipped with ice-penetrating radar.
Scientists used the remote sensing techniques to map 32,000 square kilometers of land — an area around the same size as Belgium. They discovered a landscape formed by rivers prior to the continental build-up of the East Antarctic ice sheet that would have once resembled the hills and valleys of present-day North Wales, according to a study published Tuesday in the journal Nature Communications.
What lies beneath the Antarctic ice Understanding why this specific ancient landscape survived largely unscathed could help scientists better predict the future dynamics of the East Antarctic ice sheet, which contains the equivalent of approximately 60 meters of potential sea level rise, as the planet gets warmer.
