Heading north
World’s largest iceberg set in motion
What is probably the world's largest iceberg is on its way north decades after breaking away from the Antarctic ice shelf.
Kronen Zeitung als bevorzugte Google-Quelle hinzufügen A23a broke away from the Filchner-Ronne Ice Shelf in the Antarctic in 1986, but remained stuck to the seabed for another 14 years. After breaking free in 2000, it remained trapped in circulating ocean currents. But now it has escaped, as can be seen on satellite images, according to the British Antarctic Survey, a polar research institute.
Ten times the size of Vienna
The iceberg is around 4000 square kilometers in size, around ten times the size of Vienna. In the meantime, waves and weathering have carved huge arches and cave-like depressions into the colossus, as images from a ship operated by Eyos Expeditions have shown.
It is expected that A23a will move towards the island of South Georgia. There it will encounter warmer water, break into smaller icebergs and ultimately melt, the statement said. "We are curious to see if it will follow the same path as other large icebergs that have broken off the Antarctic ice shelf. And more importantly, what impact will this have on the local ecosystem?" oceanographer Andrew Meijers was quoted as saying.
