The strange phenomenon scared researchers from the American University of Colorado, who studied the Ross Glacier in Antarctica. Experts wanted to find out how air masses affect the process of glacier melting. For this, the experts used sensitive sensors that record sound. The equipment was placed in one well under water. What was the surprise of everyone when, while listening to the material, eerie sounds were heard coming from the depths of Antarctica.
The noise frequency turned out to be incredibly low. It is almost impossible for a person to catch it. The scientists were able to hear the anomaly only after accelerating the audio.
The tone of the sounds was influenced by the weather. Perhaps this mysterious feature will help to learn the interesting properties of the glacier, as well as find cracks and melting centers.
Note that the Ross Glacier is one of the largest formations in the North Pole region. It has an area of 487 thousand km2, while the thickness is equal to one kilometer. The accelerated melting process is of concern to experts, as the rise in water will entail a large number of victims.
