Iceberg A-68 was a giant tabular iceberg adrift in the South Atlantic, having calved from Antarctica's Larsen C ice shelf in July 2017. [1][2][3] By 16 April 2021, no significant fragments remained. [4]

Jan 20, 2022 · A68 was, for a short period, the world's biggest iceberg. It covered an area of nearly 6,000 sq km (2,300 sq miles) when it broke free from Antarctica in 2017. But by early 2021, it had vanished.

Apr 21, 2021 · An enormous Antarctic iceberg whose journeys were probably the most well-documented in history has now melted away to nothing in the Atlantic ocean. A68 cracked off the Larsen C ice sheet on the Antarctic Peninsula in 2017 as one of the biggest icebergs ever.

Oct 26, 2024 · Scientists following A-68's birth and demise were able to track just what such giant icebergs do to the surrounding ocean. For its short, transient life as an iceberg, A-68 became a frozen...

Apr 17, 2021 · 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.

A68 is a good example of an Antarctic tabular iceberg, which are produced when the end of a floating glacier or ah ice sheet breaks off--termed "calving". As large as A68 was, it is not exceptional either in size or path.

Sep 30, 2017 · By August, scientists started getting their first sunlit views of the new iceberg, which the U.S. National Ice Center named A-68. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured a wide …

Apr 19, 2021 · We are now eager to analyse the data to assess how the natural balance of the South Georgia ecosystem was affected by the trail of meltwater and nutrients left in the iceberg’s wake.” A68 photographed soon after the calving in 2017.

Jan 30, 2021 · 11 December 2020 The giant A-68A iceberg could strike land this month – wreaking havoc near the waters of the South Georgia Island. If it remains on its current path, the iceberg could ground in the shallow waters offshore – …

Jan 20, 2022 · Altogether, the iceberg thinned by 67 metres from its initial 235 m thickness, with the rate of melting rising sharply as the berg drifted around South Georgia. Laura Gerrish, GIS and mapping specialist at BAS and co-author of the study says: “A68 was an absolutely fascinating iceberg to track all the way from its creation to its end.
