Iceberg the size of London breaks off Antarctica ice shelf threatening chaos at sea

Glaciologist Dr Oliver Marsh, who has returned from the British Antarctic Survey’s (BAS) Halley Research Station, said: “This was a calving we knew was coming.

“BAS has been monitoring the Brunt Ice Shelf and the chasms formed across it for over a decade.

“Since glaciologists first observed Chasm-1 widening in 2012, BAS science and operations teams have been anticipating the calving event.

“High precision GPS instruments, as well as satellite data, have been used to monitor widening of the chasm and in 2016 BAS took the precaution of moving the Halley Research Station inland to protect it.”

Other researchers have been watching the A76, which has split into three pieces labelled from A-C.
