Scientists at British Antarctic Survey are using satellite images to track the colossal iceberg A23a as it moves north out of the Weddell Sea, with a new animation showing its trajectory alongside previous large icebergs A68 and A76a. The iceberg, which calved from the Filchner Ice Shelf in 1986, was recently observed by scientists aboard RRS Sir David Attenborough, who collected seawater samples from the area. The animation has been compiled from Copernicus Sentinel-3 satellite imagery, providing valuable insights into the iceberg's movement.
