Brunt’s barrier is a ice barrierice barrier located in Antarctica. A huge platform of ice that floats on the Weddell Sea. And thanks to a great tidetide, a huge iceberg has just broken free. Now named A-81 by the U.S. National Ice Centerit is even bigger than A74, the one that made people talk about it in the region about two years ago.
Even if we will have to wait for better images resolutionresolution to determine its exact size, observers estimate it at some 1,550 square kilometers, twice the size of New York City.
Recall that the calvingcalvingunderstand, the production of an iceberg by a glacier, remains a completely natural event.
According to glaciologists, this has no connection with global warming. It’s caused by a crack known as Chasm-1 that eventually spread through the pack icepack ice after being followed by researchers for more than 10 years.
Researchers stationed at the nearby Halley base ensure that their station is not affected.
Glociologists expect it to follow roughly the same path as A74, in the coastal current AntarcticAntarctic.
