Experts head to Antartica in search of 'lost' meteorites

Scientists are preparing for an expedition to the Antarctic search for meteorites 'lost '.
These search of ferrous meteors are trained in the cores of minor planets that have been destroyed by the celestial impacts - and could provide clues to planetary creation.
UK-led team believes that the missing ferrous meteors can pose as a thin layer, a few feet under the icy landscape

The Antarctic is known to be generous in meteorites and it is easy to identify nonmetallic meteorites of dark under the clear and icy landscape.

"Until December 2015, some 34 927 meteorites have been recovered in the surface of the Antarctic, or 66.3 percent of the world total number of samples taken," reads the study published in the journal Nature.

«However, then the fall of meteorites should almost evenly spread over the surface of the Earth, meteorite collection, the data show that the proportion of ferrous meteorite recovered from the

Antarctic, 0.7%, is substantially lower than the proportion recovered after a fall in front of witnesses from the rest of the world, 5.5% - a statistical difference to above 99.9% confidence level.»

"This comparison suggests that one or several physical mechanisms are translated into a deficit apparent fall of the ferrous meteorite in Antarctica."

The team, led by the University of Manchester, makes the assumption that meteorites are missing as a result of the rays of the Sun penetrating the clear ice and heat non-metallic iron-rich rocks more of those.

This global warming melts the ice that surrounds the meteorite, sink and compensate for the ice lifts annual all - this traps all the time meteorites just beneath the surface.

However, the team recently received a research grant from the Leverhulme Trust, which will allow them to develop the necessary technology to locate hidden meteorites.

Technology will probably metal engineering detection, in which the University of Manchester has the force of specific research-based (for example, in the optimization of scanning security airport, removal of land mines, recycling and non-destructive testing). 

The researchers scored 2020 as when the expedition will take place and 2019 for the prior visit to Antarctica. And a small-scale test mission will take place on the island of Svalbard Arctic earlier in 2018. 
"We now have the opportunity to start a scientific adventure that is really exciting," said Dr. Geoffrey Evatt, a mathematician at the University. 

"If successful, our shipments will help scientists decode the origins of the solar system and cement to the United Kingdom as a leader in the meteorites and Planetary Sciences". 

The team plans to work on three sites on the continent and hundreds of miles of research stations nearby.
Such warming melts the ice surrounding the meteorite, causing it to sink and offset all annual ice upwelling - this permanently traps the meteorites just below the surface

"The notion of a layer of lack of meteorites in Antarctica was released Armageddon discussions at an interdisciplinary workshop, between a group of applied mathematicians and glaciologists, back in 2012," said Dr. Evatt.

"Having transformed by following these initial ideas in scientific reasoning farm, we have now an opportunity to put our mathematical hypothesis to the most extreme tests!"
