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. The scientists were researching the effects of climate change at the Helheim Glacier.
The team measured a four-mile area in middle Manhattan, NYC, to illustrate the monumental size of the iceberg.
In 2017, scientists estimated that a collapse of the entire West Antarctic Ice Sheet, which is two-and-a-half miles thick and about as large as Texas, would raise global sea levels by 10 feet-inundating coastal cities around the world.
The video shows a range of different iceberg formation styles captured during the calving event which began on June 22 at 11:30 p.m. local time and took place over approximately 30 minutes (the video has condensed the time of this occurrence to approximately 90 seconds).
While it's hard to get a sense of scale from the camera's wide-angle view of the separating iceberg, the berg is so big that it could partially cover the island of Manhattan, extending from the lower tip of New York City into Midtown, according to the statement.
Sea levels are rising and one of the culprits is the loss of ice from glaciers and ice sheets, victims of a warming planet. "By capturing how it unfolds, we can see, first-hand, its breath-taking significance".
When large masses of ice part from glaciers, quantities of water are shunted into the ocean and contribute to sea-level rise.
"Knowing how come icebergs are important for modelling, because the icebergs ultimately determine global sea-level rise". Meanwhile, smaller pinnacle icebergs, which are tall and thin, can be seen calving off and flipping over.
She said: "The better we understand what's going on means we can create more accurate simulations 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.
The research is being carried by NYU's Environmental Fluid Dynamics Laboratory and NYU Abu Dhabi's Center for Global Sea Level Change-both directed by David Holland.
