Like many places, the Antarctic Peninsula is falling victim to rising temperatures. However, when scientists used radar images from the Copernicus Sentinel-1 mission acquired between 2014 and 2021, they were taken aback to discover just how the fast 105 glaciers on the west coast are flowing in the summer months.

Video: 00:00:23 Using radar images from the Copernicus Sentinel-1 mission, the animation shows the A81 iceberg breaking away from the Brunt Ice Shelf on 25 January 2023. The new berg is estimated to be around 1550 sq km, which is around the size of Greater London, and is approximately 150 m thick. It calved when the crack known as Chasm-1 split northwards severing the west part of the ice shelf.
The white square indicated the final breakpoint near the McDonald Ice Rumples.
Routine monitoring from satellites offers unparalleled views of events happening in remote regions. The Copernicus Sentinel-1 mission carries radar, which can return images regardless of day or night and this allows us year-round viewing, which is especially important through the long, dark, austral winter months.

Satellite imagery confirms an enormous iceberg, around five times the size of Malta, has finally calved from Antarctica’s Brunt Ice Shelf. The new berg, estimated to be around 1550 sq km and around 150 m thick, calved when the crack known as Chasm-1 fully extended northwards severing the west part of the ice shelf.
This crack was first revealed to be extending in early 2012 after having been dormant for some decades. After several years of desperately clinging on, image data from the Copernicus Sentinel missions visually confirm the calving event.
