The five chivalrous men made an insurrection in the Spring and Autumn Period, and they rose and fell for a while. Deep space frontier Xiao takes you to watch the latest news round after round. Bian Xiao sorted it out for a long time and brought this article to everyone. Let's get to know each other.

Researchers at the University of California, Irvine, recently said that they found that the deep valley covered by Denman Glacier in eastern Antarctica is the lowest land point on the earth, which is 3,500 meters below sea level.

A new study on Antarctica may change the description of "the lowest point on the earth's land" in geography textbooks.

Previously, scientists found that the Dead Sea coast more than 400 meters below sea level is the lowest exposed land. But researchers at the University of California, Irvine, recently said that they found that the deep valley covered by Denman Glacier in eastern Antarctica is the lowest land point on the earth, 3,500 meters below sea level.

Land refers to the part of the surface that is not submerged by the ocean. The record-breaking Antarctic Canyon is the naturally formed lowest point on the earth's land and is not covered by liquid water. Mariana Trench, located in the western Pacific Ocean, is still the deepest known earth ocean, with the maximum depth of11034m.

The river bed elevation letter H of Antarctic ice sheet represents the natural geoscience map where Denman Glacier is located.

According to CNN, this six-year study of Antarctic continental bedrock was led by Mathieu Moligam, an associate professor at the University of California, Irvine. Through measurement, they found that the canyon covered by Denman Glacier is 100 km long and 20 km wide. Although the lowest point of the canyon is 3500 meters lower than the sea level, there is no seawater in it, but it is full of ice moving towards the ocean.

Denman Glacier is located in queen mary land, East Antarctica. According to the data of USGS,191211in June of, this glacier was first discovered by the Australian Antarctic expedition, and it was named after Thomas Denman, the sponsor of the expedition and then the governor of Australia.

The researchers reported the discovery at the fall meeting of the American Geophysical Society. This research paper was published in the journal Nature Geoscience on February 20 19. It is reported that the goal of this study is to create an accurate map of Antarctic continental bedrock, which is very important for better understanding how ice flows from the central highlands to the waters around Antarctica.

Detailed riverbed information of Antarctic glacier, and Figure H shows the natural geoscience map where Denman Glacier is located.

In the process of measurement, the researchers combined the radar measurement data, the high-definition movement data of glacier surface photographed by satellite and the amount of snow obtained according to the local climate model to calculate how much ice passed through the canyon and the moving speed and volume of the ice, thus estimating the volume, shape and depth of the canyon bottom. Legum said that they applied this mapping technology to the entire ice sheet and found a very deep canyon hidden under the ice sheet.

This discovery was drawn on a new map of Antarctica. The researchers said that this is the "most accurate description" of the landforms under the Antarctic ice sheet so far.

If you want to know more, the textbook will be rewritten!
