Following the breakup of Larsen C, scientists concentrate Thwaites' work, one of the hardest places to reach Earth, but is better known than ever.
In 2010, NASA launched the IceBridge Operation, a campaign to analyze links between the polar and the global climate, measuring the effects of climate change. At that time, the glacier Thwaites was one of the hardest places to reach Earth, but in addition to the latest report from the US state space agency, it is known better than ever.
The document, Wednesday, January 30th in the Science Advancement Magazine, the researchers pay special attention to the giant cavity, two-thirds of Manhattan and 300 meters high, which grows at the bottom of the Thwaites located in western western Antarctica.

The researchers believe that it is necessary to observe a smaller part of the Antarctic glacier to calculate how high sea levels are generated as a result of climate change.
Initially, the scientific team found the bottom of the Thwaites in ice and rock to melt underground water circulation.
However, the growth rate of the new hollow and the explosive growth were surprising, given that they had enough 14 million tons of ice. Especially since most of the ice were melting in the last three years.
In this regard, at the University of California, Irvin and NASA Jet Propulsion Laboratory in Pasadena, California, Dr. Eric Rignot said "years have been suspected that Thwaites was not well under the rock and now, thanks to a new generation of satellites, we can see details."
The researchers added that they discovered an ice penetration radar in the IceBridge Operation, data from the constellations of synthetic speed speeds of the Italian and German spacecraft.

Msgstr "Thanks to these data very high resolution They can be treated using a technique called interferometric radar, which below has been moved between the lower surface images, "he said.
Thwaites glacier is now responsible for around 4% of sea level worldwide, with a complete rupture and ice loss, which would increase Between 65 and 80 centimeters.
Due to actual risks National Foundation The United States and the United Kingdom's National Environmental Research Council launched a five-year deadline to measure long-term ice loss.
The problem is that there is currently no way to control soil glaciers in Antarctica; Therefore, the use of aerial or satellite data must be used to observe the glaciers' melting properties.
Scientists keep track of other monitoring information that is linked to the lower glacier connection, which is more than one place near the edge of the continent, where it rises from its bed and begins to float the sea water.
Antarctic glaciers stretch a lot of kilometers From the earth's lines, when it is floating over the open sea and when it happens, the earth's line goes backwards, giving it a chance to show off sea water at the bottom of a glacier. Fusion speed accelerates.
