Scientists Have Made a Startling Discovery in Antarctica

Scientists have made the astonishing discovery of a major river in Antarctica that was concealed by thick sheets of ice. A team of glaciologists researching how climate change is affecting glaciers came upon the river during a recent airborne radar survey. According to experts, the river extends 460 kilometers beneath the ice, a longer distance than the river Thames, which flows across southern England and through London. The journal Nature Geoscience carries a published article on the study of the waterway and its offshoots. According to glaciologists, the river may have a significant impact on the flow and melting of the glacier ice above it. It is known to scientists that water flows beneath ice sheets. However, this new research demonstrates that rivers are being formed as a result of the melting of ice. As the glacier's base loses stability, it is claimed that these freshwater channels could hasten the ice-melting process. Scientists discovered the river by combining the data from water flow modeling and airborne radar surveys. They studied a sizable area, which included ice from the Antarctic's east and west sheets as well as water flowing into the Weddell Sea. The study's base region has enough ice to increase the sea level worldwide by 4.3 meters. How quickly and how much of this ice melts depends on how slippery the ice base is. According to Martin Siegert, a glaciologist at Imperial College London in the UK and a co-author of the paper, the recently discovered river system "may greatly affect this process."
