World’s Largest Iceberg Runs Aground—What Happens Next?

The world’s largest iceberg, A23a, has run aground near South Georgia Island. It’s bigger than Rhode Island and weighs over a trillion tons.

After breaking off Antarctica in 1986, A23a stayed motionless for decades. But strong ocean currents recently pushed it into open waters.

Satellite images confirm it is now stuck on the seafloor. Scientists warn this could disrupt marine ecosystems in the region.

South Georgia is home to millions of seals and penguins. The iceberg could block their access to feeding grounds during breeding season.

As A23a melts, it will release massive amounts of fresh water, potentially affecting ocean currents and nutrient cycles.

Experts say strong currents or rising temperatures may break it apart—but if it stays grounded, it could cause long-term ecological changes.

Scientists are closely tracking its movements. Whether it moves or stays, A23a will shape the region’s future for years to come.
