The world's largest iceberg is about to enter the open ocean.
The iceberg called A-68 originally broke free from Antarctica's Larsen Ice Shelf in 2017 and weighs one-trillion tonnes.
When the iceberg broke off the glacier, an act called "calving", the A-68 had an area of about 6000 sq km, about six times larger than Auckland.
Scientists will be watching the iceberg's movements as the A-68 could be a threat to ships out on the open ocean.
Although scientists have said the iceberg has lost little of its original size, experts believe the iceberg will not maintain its form.
"With a thickness to length ratio akin to five sheets of A4, I am astonished that the ocean waves haven't already made ice cubes out of A68," Professor Adrian Luckman of Swansea University told BBC.
Luckman said he would be surprised if it survives for long as one piece out in the open ocean.
According to the BBC, the iceberg is following a predictable course.
Once it breaks over the peninsula it will travel northwards towards the Atlantic, a route scientists call the "Iceberg Alley".
