Radar imagery from the European Space Agency’s Envisat environmental satellite confirms that the massive B-15A iceberg, which is the world’s largest floating object, is on the move again after spending two months aground. The bottle-shaped Antarctic iceberg is about as large as the country of Luxembourg, the space agency said.
The drifting iceberg poses a renewed threat to a nearby pier of land-attached ice called the Drygalski ice tongue, the ESA said. The iceberg became anchored in a shallow seabed earlier this year, but the ESA said tides and currents lifted B-15A free and now prevailing currents are moving it deeper into McMurdo Sound.
