CANBERRA - An iceberg the size of urban Sydney has broken away from east Antarctica, but not due to climate change, the Australian Antarctic Divisions said on Tuesday .
The 1,636 sq km table iceberg"calved" from the Amery Ice Shelf, the third-largest on the ice continent, located between Australia's Davis and Mawson research stations, on Sept 26. The iceberg, officially called D-28, separated from the front of the ice shelf, which scientists had been monitoring closely since the early 2000s, according to AAD, an Australian government agency."We don't think this event is linked to climate change," said Helen Amanda Fricker, a professor at the US-based Scripps Institution of Oceanography.The last major calving event on the Amery Ice Shelf, which has an estimated floating ice area of 60,000 sq km, was in 1963-64.
"We knew it would happen eventually, but just to keep us all on our toes, it is not exactly where we expected it to be," Fricker said. Ice shelves are floating platforms of ice attached to coastlines."But what will be interesting to see is how the loss of this ice will influence the ocean melting under the remaining ice shelf and the speed at which the ice flows off the continent," he said.
