British Antarctic Survey abandons polar base as worrying crack grows in ice

Recommended Posts

The Halley VI ice base is in danger from a growing ice crack

Scientists at the British Antarctic Survey are abandoning their research station for the first time ever this winter after a new worrying crack developed in the ice sheet.

The renowned Halley VI ice base, from which the hole in the ozone layer was first detected, was already scheduled to be relocated 14 miles across the Brunt Ice Shelf because of an encroaching fissure in the ice.

But a new crack has been steadily growing to the north of the base, and computer modelling suggests that it could cause a large iceberg to calve away from the sheet, which could destabalise the area.

Although the British Antarctic Survey (BAS) says nobody is immediate danger, they cannot be sure that conditions would not worsen during the difficult conditions of the southern polar winter when an evacuation would be impossible.
