British Antarctic Survey The mission to determine the impact of the giant A-68a iceberg on the important marine ecosystem of sub-Antarctic South Georgia is a success according to a team of researchers and engineers, from British Antarctic Survey (BAS) and National Oceanography Centre (NOC). This week (Monday 19 April) the U.S National Ice Center declared ‘the end’ of the A68 iceberg, because its fragments are now too small to track. This coincides with the return of the mission ship to Southampton in the UK last week (13 April). The team are piloting two submersible robotic gliders deploy...

BBC News image captionWide but extremely thin: A68 was about 230m thick on average The iceberg that was for a time the biggest in the world is no more. A68, as it was known, covered an area of nearly 6,000 sq km (2,300 sq miles) when it broke away from Antarctica in 2017. That's like a small country; it's equal to a quarter of the size of Wales. But satellites show the mega-berg has now virtually gone, broken into countless small fragments that the US National Ice Center says are no longer worth tracking. A68 calved from the Larson C Ice Shelf on the edge of the Antarctic Peninsula, and fo...

Iceberg A68 in South Atlantic ocean keeps getting smaller and smaller as another portion detaches this week This new ice portion, christened A68g, measures 33 miles on its longest axis and 11.5 miles on its widest axis A68 broke away in 2017 due to iceberg calving – the breaking away of masses of ice from the edge of a glacier It was originally more than three-and-a-half times the area covered by Greater London but it's breaking up fast

HARRY BAKER, LIVE SCIENCE 28 DECEMBER 2020 The world's (former) largest iceberg continues to break apart into smaller pieces on the doorstep of a major marine wildlife haven and home to millions of macaroni and king penguins in Antarctica.    This comes less than a week after the mammoth iceberg, known as A68a, first split in two, Live Science recently reported.  Scientists at the US National Ice Center (USNIC) spotted the two newest pieces, A68e and A68f, on December 22 using images from the Sentinel-1A satellite, according to a USNIC statement. This means that there are now four se...
