A23a, arguably the world’s largest and oldest iceberg which has been wandering through the South Atlantic and headed for the British Overseas Territory of the South Georgia Islands since last month, has been reported not to have changed course this week nor upped nor melted, thus posing a serious threat to the local fauna. Earlier this week, it was spotted 173 miles (280km) away.
Argentina's Coast Guard (PNA) Thursday issued a statement explaining how it is monitoring the displacement of the A23a iceberg, which was reported to be headed for the South Georgia Islands.
According to the British Antarctic Survey (BAS), the 3,600 square kilometer iceberg known as A23a broke off from Antarctica and was reportedly going adrift in the South Atlantic, probably towards South Georgia Island. It is arguably the world's largest and oldest iceberg, with ice sheets 400 meters thick, and weighing almost one billion tons.
Scientists aboard the Falklands flagged RRS Sir David Attenborough collected samples of seawater around the A23a mega iceberg, the largest iceberg in the world. New video footage shows the enormous iceberg, some 3,900km2 and 400m tall, twice the size of Greater London stretching out into the distance beyond the research vessel.
