Researchers from the British Antarctic Survey recently captured the first close-up video of A81, an enormous iceberg that broke off the Brunt Ice Shelf in January.
An enormous iceberg in Antarctica — an ice slab that's so massive, it has a surface area greater than Los Angeles — recently got its first aerial cameo, which showed off its mind blowing size.
The ice slab, named A81, was birthed from the Brunt Ice Shelf on Jan. 22 after a gigantic chasm finally snapped through the 490-foot-thick ice shelf, after having been widening for nearly a decade. A81 covered an area of around 600 square miles when it broke free from Antarctica and has since traveled around 93 miles into the Weddell Sea.
Researchers from the British Antarctic Survey's Halley Research Station captured the footage of A81 as they flew over the iceberg on their journey home. The video, released March 13, shows the enormous scale of the hefty berg, which looks like its own ice sheet and is birthing tiny icebergs along its coastline.The Halley Research Station was previously based on the ice that now makes up A81 but was moved further inland after the chasm was spotted.
"This was a calving [event] we knew was coming," Oliver Marsh , a BAS glaciologist who recently returned from the Halley Research Station, said in a statement . The BAS team first noticed the chasm in 2012 and has been expecting the immense chunk of ice to break off ever since, he added.
Glaciologists are also keeping a close eye on another giant iceberg, A76A, which broke off from Antarctica's Ronne Ice Shelf in May 2021. The mammoth slab of ice is the biggest iceberg on the planet and the largest remaining piece of A76, which covered an area of around 1,700 square miles , or larger than the state of Rhode Island, when it calved from the ice sheet.
