A23a: World’s biggest iceberg on the move

Share to Google Classroom

The world’s largest iceberg, A23a, is making its way through the Antarctic Ocean.

Covering an area of approximately 2,400 square kilometers, it’s more than twice the size of Auckland.

Originating from the Filchner Ice Shelf in 1986, it is not only the largest iceberg but also among the oldest, boasting a thickness of around 400 meters.

After being stuck to the ocean floor for over 30 years, A23a has started drifting rapidly in the past year, and scientists anticipate it will soon exit Antarctic waters.

The reason for its movement after decades is still under investigation, and researchers are closely monitoring its journey.
