See millions of years old radio stations under the Greenland ice sheet

US geologists on April 17 said they have discovered a raw radio station (areas in which subsoil soil is permafrost) from the pre-glacial period kept intact throughout. 2.7 million years below the ice sheet on Greenland.

The study, published in the journal Science, shows that the Greenland radio station was discovered in an almost intact state 3 kilometers deep beneath the ice sheet. This is different from the common freezing situations in nature, when glaciers often destroy everything on the covered land, from plants, land to the top floor of hard rock.

The University of Vermont's Paul Bierman research leader said the ice sheet was tight on the surface of the station, creating a "refrigerator" to preserve this ancient land. Even during the warming periods of the Earth, the center of Greenland remained stable and the ice was not melted, protecting the monumental area for millions of years from the effects of climate change.

The scientists also analyzed 17 samples taken from the Island Summit Research Station in 1993. The results showed that the ground here had about 200,000 to 1 million years of natural existence before being covered by ice. covered. Measurement of nitrogen and carbon levels also found organic matter, a sign that the area could be partially covered by the forest.
