2021-02-28 Breaking off of Brunt North

Sentinel 1B SAR image composite, Copernicus data

With Summer ending in Antarctica, the surprising new (end 2020) crack north of Halloween crack ruptured and the calving of the Brunt-North shelf is complete. Brunt West is still attached along a 2 km stretch. As winter is coming near, West Brunt may freeze-in and survive until next Antarctic summer. Only time will tell.
