Huge iceberg breaking up off South Georgia Island is still a threat
What effects on wildlife and the ecosystem the icebergs will have are unknown.
What was the largest iceberg on Earth is threatening to come to a halt soon in a pristine Antarctic wildlife sanctuary that’s home to penguins, seals, and a small population of endangered blue whales.
The iceberg, labeled A68, broke off from the Larsen C ice shelf on the east coast of the Antarctic Peninsula in 2017. It had been slowly inching north until this year, when an ocean current quickly propelled it into the Southern Atlantic Ocean. (Find out about how climate change is melting the Antarctic Peninsula.)
About 95 miles long and 30 miles wide at its widest point, the iceberg covers an area of roughly 1,500 square miles and extends 500 to 600 feet underwater. Satellite images show it
