World’s largest iceberg emerges from vortex, moving northward
The world’s largest iceberg, A23a, caught in a whirlpool in Antarctica, has broken free.
The British Antarctic Survey said the iceberg has drifted northward.
Dr. Andrew Meijers, a marine scientist and researcher with the organization, noted it is exciting that A23a is on the move again.
The surface area of A23a was measured to be about 1,544 square miles and 400 meters (1,212 feet) in thickness.
A23a broke away from the Antarctic coastline in 1986.
It moved for the first time in more than 30 years last year, before it was caught in a huge whirlpool in the spring.
