Academia's attention is being focused as a huge'ice land' connected to Antarctica has recently been observed to have two rivers.
Local time on the 1st, the BBC and other foreign media reported that 1,270km² of ice had fallen from the'Brent Ice Shelf' in Antarctica.
It is more than twice the size of Seoul, which is about 605 km².
On the 27th of last month, Antarctic researchers confirmed the formation of cracks hundreds of meters wide on the Brunt Ice Shelf.
The satellite cameras that took pictures of the Antarctic region clearly captured the cracks slowly opening up and the ice shelf splitting in two.
The ice shelf is a huge ice field that connects to Antarctica and serves as a gateway that must be passed through to enter the continent.
However, it is only ice floating on the water, and it is known that such a'calving' phenomenon appears depending on various factors such as ocean currents.
There were voices of concern as the British Antarctic research facility, Halley Institute, was located on the Brunt Ice Shelf, but fortunately, the situation did not cause any damage thanks to the inland location of the institute in 2017. It is also reported that 12 researchers who stayed at the institute had been away from the institute since mid-last month.
Since the first large-scale segregated glaciers have been observed on the Brunt Ice Shelf since the early 1970s, questions have also been raised as to whether it is the effect of global warming
. Experts said, "There is no clear evidence that this phenomenon is related to global warming." "There is." Separation glaciers are not known to affect sea level rise.
"This is a remarkable situation," said Simon Garrard, a British Antarctic researcher.
"Since such huge icebergs are rare, we are not sure what the potential consequences will lead. We will be watching closely the progress of the situation. "
