Der Bruch „Chasm 1“ (von Nord nach Süd) und der „Halloween Crack“ (von West nach Ost) sind Beispiele für die große Eisschelfdynamik am Rande des antarktischen Kontinents. Bereits 2016 wurde die britische Station Halley daher auf die landeinwärts gelegenen Schelfeisfläche verlegt.

Glaciologists have been closely monitoring the many cracks and chasms that have formed in the thick Brunt Ice Shelf over the past years.
Routine monitoring by satellites will help us monitor the ice shelf stability: esa.int/Applications/O

The Sentinel satellites have once again demonstrated their capabilities are second to none in monitoring such natural #iceberg calving events. This #Sentinel2 followed this morning's #Sentinel3 image. #Sentinel1 will follow later with a radar image perspective.
