A23A: World’s Biggest Iceberg on the Move Again

ANTARCTICA – The world’s largest iceberg is on the move again, scientists from The British Antarctic Survey say.

The A23A Iceberg , which is said to be slightly bigger than Rhode Island, had been spinning in the same spot in the Southern Ocean for months.

It originally broke off from the Filchner-Ronne Ice shelf in 1986 and stayed grounded on the Weddell sea floor for over 30 years.

Now drifting toward warmer waters near South Georgia, A23A is expected to break up and melt.

Scientists say it won’t raise sea levels but are studying how icebergs like it affect ocean nutrients, ecosystems, and carbon cycles.
