The world’s largest iceberg has run aground off the coast of a remote island in the Atlantic Ocean, according to British researchers.

The world's largest iceberg appears to have run aground off the coast of a remote British island home to millions of penguins and seals — potentially threatening local wildlife, but also providing an opportunity for research into such rare "megabergs.

The largest iceberg in the world has run aground in the South Atlantic Ocean. The enormous wall of ice, known as A23a, was on a collision course with South Georgia Island. The island is mostly uninhabited by humans but is home to millions of seals and penguins.

The one-time world's largest iceberg has run aground in shallow waters off the remote British island of South Georgia. The iceberg, known as A23a and approximately twice the size of Greater London, appears to be stuck and is expected to break apart along the island's south-west shores.
