Scientists have captured the moment a four mile long iceberg broke off a glacier in eastern Greenland.

The calving happened on June 22 and saw an iceberg a third of the length of Manhattan break off the glacier.

The team of researchers and scientists at the site captured the event which caused other icebergs to separate with some flipping over entirely.

Capturing the entire event on camera can help scientists examine how large icebergs may affect future sea levels.

David Holland, a professor at NYU’s Courant Institute of Mathematics and NYU Abu Dhabi, who led the research team, said: “Global sea-level rise is both undeniable and consequential”.

“By capturing how it unfolds, we can see, first-hand, its breath-taking significance,” he added.

The calving began at 11.30pm on June 22 when the four-mile-long iceberg started splintering off the Helheim Glacier.

It took just 30 minutes for the iceberg to completely separate and the researchers condensed the event into a minute-and-a-half long clip.

The clip shows the giant iceberg breaking off and then drifting into the sea.

Denise Holland filmed the calving and said: “Knowing how and in what ways icebergs calve is important for simulations because they ultimately determine global sea-level rise.

“The better we understand what’s going on means we can create more accurate simulations to help predict and plan for climate change.”

Experts at NYU have said it was a tabular iceberg, meaning it is wide and flat.

As it breaks away from the glacier, other icebergs – known as pinnacle bergs meaning they’re tall and thin – splinter off as well and flip over.

The footage shows the iceberg crashing into another one as it floats down the fjord before it splits in two.

Scientists are currently researching how the melting ice sheets could affect the world’s sea levels as global temperatures continue to rise.

Holland added: “The range of these different iceberg formation styles helps us build better computer models for stimulating and modelling iceberg calving.”
