American and British researchers have made a remarkable discovery under Antarctica. Using radio waves and radio-ultrasound survey techniques, they revealed the existence of a landscape hidden under the ice for several million years. This territory (The notion of territory has taken on increasing importance in geography and particularly in…), larger than Belgium, once sheltered forests and certainly animals.
This 32,000 square kilometer expanse was once home to forests and probably animals.

To detect this hidden world, the researchers used an innovative approach. They sent radio waves through the ice from a plane (A wave is the propagation of a disturbance producing a reversible variation in its path…) A plane, according to the official definition of the International Civil Aviation Organization…) flying over the region, then analyzed the echoes returned. This technique, known as radio-ultrasound survey, allowed them to map the landscape. arrangement of features, characters, shapes of a…) under the ice. Secondly, they superimposed this mapping on satellite images already available, allowing them to trace the valleys and ridges.
The landscape thus discovered, frozen in time, is located at a depth of more than two kilometers below the surface of Antarctica (Antarctica (pronounced [ɑ̃.taʁk.tik] Listen) is the continent most…). It has features such as deep valleys and steep hills, resembling common land regions. Before being buried under ice, it likely supported a rich ecosystem with forests and diverse wildlife.
This landscape is currently preserved, kilometers from the edge of the ice cap. However, Antarctica is experiencing higher temperatures than before, and melting ice might eventually expose this hidden world to light. This discovery highlights the fragility of Antarctic ecosystems and the need to protect these unique regions from environmental threats.
This discovery shows that the Earth still harbors buried secrets. Researchers hope to find other hidden landscapes and learn more regarding the geological history of our planet. However, they remind us that global warming (Global warming, also called global warming, or…) poses risks for these unexplored territories, thus underlining the urgency of acting to preserve our environment (The environment is everything which surrounds us. It is all the natural elements and…).
