Gigantic Iceberg Measuring 1636 Km2 Breaks Off In Antarctica

By

A enormous iceberg bigger than Los Angeles or Greater London has separated from the Amery Ice Shelf in Antarctica, the largest to do so in more than half a century.

The table iceberg, named D-28 by scientists, broke off the shelf in east Antarctica on September 26. It measures 1636 square kilometres (632 square miles) in area, is 210 metres (689 feet) thick and weighs a massive 315 billion tons. The iceberg will now be tracked because it poses a potential hazard for shipping.

Scientists from the Australian Antarctic Program, Institute for Marine and Antarctic Studies and the Scripps Institution of Oceanography, San Diego have watched developments on the ice shelf for almost 20 years, after first spotting a rift developing in the early 2000s.

Helen Amanda Fricker, a glaciologist at Scripps, said researchers had predicted a calving event between 2010 and 2015 — some 50 years on from the last one which occurred on the Amery in 1963-4.

In a statement released by the Australian Arctic Division, she said: “I am excited to see this calving event after all these years. 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.”

She and her colleagues had been keeping an eye on a nearby location known as “Loose Tooth” since 2002 because of its shape and its precarious attachment to the ice shelf.
