Scientists have found out that it is the world’s deepest land canyon is thousands of feet below a glacier in Antarctica.
Glaciologists, led by the University of California, Irvine, have unveiled what they describe as ” the most accurate portrait yet of the contours of the land under Antarctica’s ice shelf. The research was presented this week at the fall meeting of the American Geophysical Union in San Francisco, and published in the journal Nature Geoscience.
The Antarctic topographic map, which is called BedMachine, helped the experts to find out the planet’s deepest land canyon in Denman Glacier, East Antarctica.
THOUSANDS OF THE STRANGE HOLES WAS DISCOVERED OFF THE COAST OF CALIFORNIA
The Experts use an array of data, including information from the satellites on the ice to flow into the movement, in order to shed light on the Antarctic.
Scientists have released an in-depth topographic map of Antarctica.

“The older maps, was suggested as a shallow canyon, but it wasn’t possible, but something was missing,” Mathieu Morlighem, UCI professor of Earth system science and the study’s lead author, said in a statement. “With the conservation of the mass, through the combination of existing radar survey and ice motion data, and we know how much ice is flowing through a canyon, which, by our calculations, will reach 3,500 m [11,483 feet, or 2.2 miles] below the level of the sea, the lowest point in the country. Since it is relatively small, it is too deep to be that a lot of the ice mass, to reach the coast.”
By way of comparison, the average depth of the ocean is about 12,100 feet, or 2.3 miles, according to NOAA. In the deepest part of the ocean, however, is 36, 200 feet, or 6.9 miles, on the southern end of the Mariana Trench in the Western Pacific ocean.

As a result of new research in the Antarctic, scientists are now saying that they will be better able to predict the effects of climate change on the african continent.
Other discoveries were also unveiled at the fall meeting of the American Geophysical Union. In a separate project, scientists have announced the discovery of thousands of mysterious holes in the sea floor off Big Sur, California, usa.
Researchers at the Monterey Bay Aquarium Research Institute (MBARI) were included in a survey of the deep-sea floor off Big Sur, and when they found out that the strange holes in them.
THE INCREASED ANTARCTIC SEA ICE MAY HAVE CONTRIBUTED TO PAST ICE AGES
The larger the holes, which is described as pockmarks, are, on the average, about 600 feet wide and 16 feet deep. In a statement, MBARI noted that, for the first time to discover a few of the pockmarks in the year 1999. However, subsequent research by MBARI, and other organizations that have been revealed to be about 5,200 pockmarks scattered across 500 square miles.
Thousands of small holes, known as micro-depressions. you have been discovered. Scientists have spotted about 15,000 in micro-depressions, which are, on average, 11 meters wide and 3 meters deep.

For the first time, researchers have also conducted extensive mapping of the sea floor at the Bikini Atoll in the remote Pacific Ocean, the site of testing for the dropping of atomic bombs between 1946 and 1954.
