A huge iceberg has broken the ice shelf in Antarctica, just 12 miles (19 km) from where British scientists work at a research station. The iceberg is 490 feet (150 meters) thick and 600 square miles (1,550 square kilometers) in area. It collapsed at a huge crack that split the ice shelf, known as Chasm-1, which has been growing about 2.5 miles (4 kilometers) every year since 2012.

According to the British newspaper “Daily Mail”, the GPS sensors began to pick up movement in Chasm-1 between 7 pm and 8 pm on Sunday, when it extended to nearly 40 miles (60 kilometers), across the entire shelf.

All 21 staff working at Halle Research Station with the British Antarctic Survey (BAS) were completely safe, and were preparing for the eventuality.

“Ice shelf measurements are made several times a day using an automated network of high-accuracy GPS devices that surround the station,” said Professor Dame Jane Francis, Director of BAS.

This measures how the ice shelf is deforming and moving, and compares with satellite images from ESA, NASA and the German TerraSAR-X satellite. All data is sent back to Cambridge for analysis, so the team knows what’s going on even in the Antarctic winter, when it’s not. There will be staff at the station.

It is dark for 24 hours and the temperature drops below -58 degrees Fahrenheit, and glaciologists confirmed that the area of ​​ice the station sits on remains unaffected by the event.
