The currently largest iceberg in the world is moving comparatively quickly away from Antarctic waters. This was announced by the European space agency Esa, citing satellite images. The colossus with the name A23a broke off from the Filchner-Ronne Ice Shelf in 1986, but remained stuck on the seabed for a long time. It had loosened up by 2020, but is only now starting to gain momentum, driven by winds and currents.
A23a is around 4,000 square kilometers in size, i.e. around 4.5 times the size of Berlin. Like most icebergs from the so-called Weddell sector, it will probably end up in the South Atlantic, according to ESA.
