Chinese find world’s largest canyon below Antarctic
Researchers from China’s 32nd scientific expedition to the Antarctic have discovered the largest known canyon on the Earth beneath an Antarctic ice sheet, Xinhua News reported. It is more than 1,000 kilometers long (621 miles) and 1,500 meters (almost a mile) deep.
Discovered near the Princess Elizabeth Land, the maximum width at the top of the canyon is 26.5 kilometers (16 miles). This is the first time that any large canyon has been found in the region.
According to data collected on the site, Chinese scientists made two other major scientific discoveries there, said Sun Bo, vice director of China’s 32nd Antarctic expedition team.
The second big discovery is that there are numerous sub glacial lakes and water channels beneath the Antarctic ice sheet. These lakes and bodies of water are interconnected.
The third finding is that the temperature of deep ice in Princess Elizabeth Land is noticeably higher than in other regions, which makes it easier for ice to melt, meaning that lakes and other water systems form more easily.
