The World’s Largest Iceberg A23a Breaks Free and Heads Towards the Southern Ocean

The world’s largest iceberg, A23a, has broken free from the Antarctic ice shelf and is heading towards the Southern Ocean 1. At almost 4,000 square kilometers (1,500 square miles), it is roughly three times the size of New York City 1. This is a rare event, and scientists are closely monitoring its trajectory 2.

The Journey of A23a

A23a is currently on the move for the first time in more than three decades 3. It is expected to anchor in the shallow waters around the Southern Ocean or move past it in the coming days 4. The iceberg is shaped like a closed hand with an index finger pointing forward and is about 95 miles long and 30 miles wide at its widest point 4.

The Impact of A23a

The movement of A23a could have a significant impact on the environment and wildlife in the Southern Ocean 1. The iceberg is expected to release freshwater into an ecosystem adapted to saltwater, which could affect the feeding grounds of South Georgia’s wildlife 4.

The Future of A23a

It is unclear how long A23a will remain intact and in place 4. Scientists are eagerly watching to see what it does next 4.

how do scientists track iceberg movements

Scientists use various techniques to track iceberg movements. One technique is to drop satellite tracking beacons onto the icebergs, which send a signal showing their location, much like a GPS system. These beacons are positioned either by landing on the iceberg in a helicopter or by dropping the beacon – attached to its own mini-parachute – from an airplane 1. Another technique is to use radar and sonar to detect icebergs in the open sea 2.
