Currently, scientists investigate the circumstances and cause of its occurrence.
In Antarctica discovered a giant mysterious hole, which is in size comparable to lake superior in North America.
Exploring the hole Professor Kent Moore notes that she looks like “someone punched the ice.”
According to scientists, usually polynyas are formed relatively close to the borders of the ice and the sea. But in this case we are talking about hundreds of kilometers separating the hole from a line in section. Thus, the nature of its appearance is a real mystery to researchers.
It appeared on 9 September in the area of the Sea Weddel. It is known that approximately in the same place there was the hole in the 70-ies of the last century. But then there was no possibility to study it with the help of the satellite, thus the cause of its occurrence and remained unexplored.
