Researchers also managed to capture on camera a video that shows the noticeable violence and speed of the ice breaking event that is now ongoing. This can give researchers a sense of how the overall global climate is changing. The resulting iceberg, broken off from Greenland's Helheim Glacier, would stretch.
Known as calving, the melting and breaking-up of ice sheets has global significance, causing sea levels to rise.
According to the latest predictions, if the Western Antarctic Ice Sheet collapsed it could cause global sea levels to rise by ten feet, overwhelming coastal cities around the world like NY and Abu Dhabi.
The event, which began at 11:30 p.m. local time on June 22, unfolded over 30 minutes, but the footage is sped up so the calving happens in just 90 seconds, according to a statement released by the researchers. This attracted a lot of attention to an extraordinary event, because such data was compared to the distance from the bottom to the middle of Manhattan in NY.
But even though the icebergs tossed into the sea here are contributing to sea level rise, scientists still don't know exactly how such break-ups work.
A team of scientists from New York University captured a video of a 4-mile iceberg breaking away from a glacier in eastern Greenland.
"Knowing how come icebergs are important for modelling, because the icebergs ultimately determine global sea-level rise". Apart from the large chunk thin and tall icebergs known as pinnacle bergs also drift out to sea.
The team say they are continuing to study the causes of rising sea levels in an effort to help predict and plan for climate change.
The video shows a tabular (wide and flat) iceberg separate, then travel down the fjord where it smashes into another iceberg.
"Global sea-level rise is both undeniable and consequential", said research team leader David Holland.
"The range of these different iceberg formation styles helps us build better computer models for simulating and modeling iceberg calving", explains Denise Holland.
