Deepest Land Depression Discovered in Antarctica
Only ocean trenches are deeper.
Scientists from the University of California have found the deepest land depression on Earth in Antarctica, under the Denman Glacier. This is reported by the BBC.
The depth of the discovered depression is 3.5 km below sea level. Only ocean trenches are deeper. The scientists call this discovery very important, as it will help study future changes at the South Pole.
They plan to study continental rocks, as well as previously unexplored mountain ridges under the glacier. There is a suggestion that they may influence the movement of melting glaciers. Previously, Antarctica's topography was studied using radars that sent microwave pulses. There are still areas about which almost nothing is known.
To study previously unknown areas, the professor from the University of California proposed using the physical law of conservation of mass. According to him, if the amount of ice fitting into the depression and its speed of movement are known, then the depth and the unevenness of the bottom of the hidden gorge can be determined from the volume of ice.
Until this discovery, the lowest point on land was considered to be the shore of the Dead Sea, whose depth is 413 meters below sea level. The deepest oceanic point is the Mariana Trench, which is 10,994 meters below sea level.
