NASA stated on its website that when photographing the North Pole from the air, strange holes appeared in the Arctic ice. The cause of the formation of these holes has not yet been determined.
It is reported that experts discovered the holes while mapping ice levels along the east coast of the Beaufort Sea.
Researchers pointed out that, relatively speaking, the ice in this area has not been formed for a long time. It is obvious that the ice layer is thin and soft, and traces of fold lines formed by the collision of two ice layers can be seen on its surface. However, holes How it was formed is still unclear.
Experts believe the holes may have been chewed out by marine life, such as seals. Alternatively, warm air currents could be blamed for their formation.
However, experts also pointed out that this may involve an undiscovered natural phenomenon.
