Sentinel satellite captures birth of behemoth iceberg

Over the last few months, a chunk of Antarctica's Larsen C ice shelf has been hanging on precariously as a deep crack cut across the ice. Witnessed by the Copernicus Sentinel-1 mission, a lump of ice more than twice the size of Luxembourg has now broken off, spawning one of the largest icebergs on record and changing the outline of the Antarctic Peninsula forever.
The fissure first appeared several years ago, but seemed relatively stable until January 2016, when it began to lengthen.

Huge Antarctic iceberg finally breaks free

After months of 'hanging by a thread' a vast iceberg the size of Norfolk has finally broken off Antarctica's Larsen C Ice Shelf. Around 30 metres of this 190m thick block of ice sits above the sea surface.
Scientists now have opportunities to study the stability of the remaining ice shelf, as well as understanding how new biological communities might occupy the newly exposed ocean and underlying seabed areas.

Giant iceberg splits from Antarctic

One of the biggest icebergs ever recorded has just broken away from Antarctica.
The giant block is estimated to cover an area of roughly 6,000 sq km; that's about a quarter the size of Wales.
An US satellite observed the berg on Wednesday while passing over a region known as the Larsen C Ice Shelf.

Giant iceberg in the making

All eyes are on Antarctica's Larsen C ice shelf as a deep crack continues to cut across the ice, leaving a huge chunk clinging on. When it eventually gives way, one of the largest icebergs on record will be set adrift. Even before the inevitable happens, ESA's CryoSat mission can reveal some of the future berg's vital statistics.

Antarctic ice crack takes major turn

There has been an important development in the big crack cutting across the Larsen C Ice Shelf in Antarctica.
The fissure, which threatens to spawn one of the biggest bergs ever seen, has dramatically changed direction.
"The rift has propagated a further 16km, with a significant apparent right turn towards the end, moving the tip 13km from the ice edge," said Swansea University's Prof Adrian Luckman.

Plane flies along Antarctica's giant Larsen crack

The British Antarctic Survey (BAS) has released new footage of the ice crack that promises to produce a giant berg.
The 175km-long fissure runs through the Larsen C Ice Shelf on the eastern side of the Antarctic Peninsula.
If it propagates just 20km more, a block of ice a quarter the size of Wales will break away into the Weddell Sea.

Larsen ice crack continues to open up

The crack that looks set to spawn a giant iceberg in the Antarctic has continued to spread.
The rift in the Larsen C Ice Shelf has grown a further 10km since 1 January.
If the fissure propagates just 20km more, it will free a tabular berg one-quarter the size of Wales.

Huge Antarctic iceberg poised to break away

An iceberg expected to be one of the 10 largest ever recorded is ready to break away from Antarctica, scientists say.
A long-running rift in the Larsen C ice shelf grew suddenly in December and now just 20km of ice is keeping the 5,000 sq km piece from floating away.
Larsen C is the most northern major ice shelf in Antarctica.
