What are the reasons for the mysterious ice caves in the Arctic
4hw.com.cn: Recently, according to foreign media reports, NASA found a mysterious ice cave in the Arctic, but it disappeared just minutes after taking photos. It is reported that there should be no ice cave in this extremely cold sea area. This magical phenomenon has aroused heated discussion. What's the matter with the Arctic? Let's have a look.
On April 20, the staff uploaded the photos to the official website of NASA and named them "April puzzle", which triggered a large-scale discussion among netizens. After reading the pictures, some netizens left a message doubting whether the official mistook the pictures of outer space for those of the Arctic Ocean.
Some people think it's the pores made by seals breaking ice to breathe. Michael, a scientist at the ice and snow data center in the United States, doesn't agree. He thinks it may be a cave formed by the gravity of ice and snow.
According to the glaciologist Schumann, this may be a random natural phenomenon caused by the outflow of underground hot springs, or a local abnormal natural phenomenon caused by climate warming.
NASA staff member Sontag wrote in the log: 'in my memory, I have never seen such a magical phenomenon. It only existed for a few minutes. '
