A SLOW START. In July 2017, an iceberg the size of Delaware detached from the Antarctic ice shelf. Over the next year, the iceberg simply chilled close to home.

“When it first calved away, Iceberg A68 was around 400 times as long as it was thick – very different from the shape one normally imagines an iceberg to be,” Prof Luckman told The Independent.

Iceberg A68 was formed in July 2017 when the trillion-ton mass broke off of Antarctica's Larsen C ice shelf The berg — the third-largest on record — has since drifted north to the Atlantic ...

Enormous iceberg A68 was the first to be trackable on an almost daily basis. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

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.

The A68 iceberg was born—a chunk of ice the size of Delaware with a mass of about 10 percent of the shelf itself. For most of 2017, the berg didn’t move much.

A68's recent turn into the open Weddell Sea may now accelerate that timeline, though. In the case of B15, the second-biggest iceberg in recorded history, the process has taken nearly two decades.

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 ...

Iceberg A68 made up about 12% of the Larsen C ice shelf's area. Luckman and others say the calving is a natural process, and that it won't contribute much to sea-level rise.

A68 weighed billions of tonnes and was bigger than the size of Norfolk when it broke away from the Larsen C ice shelf in the Weddell Sea on the edge of the Antarctic Peninsula in mid-2017.

“When it first calved away, Iceberg A68 was around 400 times as long as it was thick – very different from the shape one normally imagines an iceberg to be,” Prof Luckman told The Independent.
