WATCH: Huge Iceberg Breaks Away From Antarctica
This is the giant iceberg which is more than a quarter of the size of Wales and has broken off an ice shelf in Antarctica.
Weighing a staggering trillion tonnes it is one of the biggest ever recorded.
Experts fear the dramatic loss could trigger the whole collapse of the Larsen C Ice Shelf and cause sea levels to rise.
A spokesman from the British Antarctic Survey said the iceberg, which measures 2,200 square miles, had been “hanging by a thread” for months.
Scientists will now study the shelf to look at how its newly exposed ocean and seabed areas are populated with life.
