CNN News:科学家在南极发现地球陆地最低点

What body of water is located along the border between Israel and Jordan? The Dead Sea, The Sea of Galilee, The Gulf of Aqaba, of the Red Sea. It's the salty Dead Sea that's between Israel and Jordon and it has the lowest elevation on Earth's surface.
And though researchers say they found a place that's considerably lower than that, setting a new record for the deepest point on land. You can't really visit it and you can't really even see it. The Denman Glacier is located in Eastern Antarctica. Glaciologists at the University of California were mapping it out using new technology. They were combining radar measurements, satellite information, and snow accumulation data and they say this allowed them to locate a valley that's hidden underneath the ice sheet.

The trough is reportedly about 62 miles long and 12 and a half miles wide but here's the kicker —it's deep. Researchers say it plunges two miles below sea level which it would make it more than a mile deeper than the bottom of the Dead Sea. Of course, the ocean's deepest trenches are much lower than this. But what we're talking about is the lowest point on land. And the Antarctic trough apparently has no ocean water. Scientists say it's filled with ice that flows toward the Antarctic coast. They're hopeful that their research will help scientists study the continent for decades to come.
