An unexpected phenomenon in Antarctica can pose problems to humanity

These are tremors that have been recorded by a group of scientists in Chicago and the discovery may be essential to better understand global warming.

A group of scientists at the University of Chicago placed seismometers in two locations near seasonal meltwater lakes on the McMurdo ice Antarctic, United States. "In these areas, we have recorded tens, hundreds, even thousands of nocturnal tremors," said study co-author Douglas MacAyeal, a professor of geophysics and glaciology, in a statement.

The result can help scientists understand the melting of glaciers and explain the disintegration of large ice shelves. Climate change is not new. Antarctic This is true, but specialists always determine how, where and why.

"In these ponds, there is often a layer of ice above the melted water below, like in a frozen lake at the top.When the temperature cools at night, the ice at the summit contracts and the Water underneath expands when it freezes.This deforms the top hood and eventually breaks in a snap of a finger. "

Such a discovery allows us to understand some of the processes surrounding the melting of tanks on ice platforms. "It can be very useful to add this to our other ways of monitoring the ice," said Professor MacAyeal.

NASA has announced that an iceberg twice as big as New York … would be released from Antarctica!
