Giant iceberg A-68a scrapes seafloor and breaks into two. Its current trajectory is unknown It's currently drifting towards Georgia, US. A massive iceberg once considered the world’s largest has just lost its leading position by splitting in two and losing a big chunk the size of Queens and the Bronx combined. The A-68a berg first split from Antarctica’s C ice shelf in 2017 and has been drifting to the north ever since The iceberg’s position on December 17th. Image credit: ESA A-68a is essentially a moving frozen island, with cliffs that rise up 30 meters above sea level. It has already drifted about 1,400km north through an area known as “iceberg alley” and is now about 500km away from South Georgia. It’s a track that many icebergs have taken, but the ultimate fate of A-68a is still hard to predict.
