Iceberg A-68-A, 1/4 The Size Of Wales, Has Traveled 1,000 km Since Calving In July 2017
hree years ago, in July 2017, a gigantic iceberg a quarter the size of Wales split off the Larsen C ice shelf in Antarctica. The berg, known as A-68, was the fourth largest iceberg ever, and is currently the biggest in the world. This is despite having shed two pieces, each a few hundred square kilometres, designated A-68B and A-68C. The main body is now called A-68A.
In its first year the iceberg stayed close to the Larsen Shelf, moving no more than about five kilometres, as it was hemmed in by sea ice. In September 2018 strong winds broke A-68 free. Since then it has been moving towards South America, picking up speed. A-68A has now reached the South Orkney islands, more than a thousand kilometres from its starting point.
The European Space Agency’s Copernicus Sentinel-1 radar satellite has been monitoring the berg’s progress. Radar is helpful in tracking even such a large object, as the Antarctic is dark through the winter months and obscured by cloud for much of the rest of the year.
