The video shows a four-mile (6.4-km) iceberg, which the scientists point out would reach from lower Manhattan to Midtown in New York City, breaking away from the glacier and washing into the sea, .

Thus far, according to the NYU scientists, the Thwaites Glacier-part of the West Antarctic Ice Sheet-has already drained a mass of water that's roughly the size of Florida.

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). - "Catching as it unfolds, we can see its value".

The video depicts Helheim Glacier and was shot by New York University's Denise Holland.

The team watched the edge of the HELHEIM glacier, one of Greenland's largest glaciers along the Eastern edge of the Greenland ice sheet.

In April this year, New York University received a $2.1 million, five-year grant from the National Science Foundation to better understand Antarctic glaciers and the forces behind sea-level rise.

The impact could see the largest desert in the world turn lush green as the rise in temperature causes the rain belt surrounding Earth to swell. "The better we understand what is happening, the more accurate the simulation we can create to predict and plan for climate change", said David Holland.

How can this video help investigations into sea level rise?

"Knowing how and in what ways icebergs calve is important for simulations because they ultimately determine global sea-level rise", Denise Holland, the logistics coordinator for NYU's Environmental Fluid Dynamics Laboratory and NYU Abu Dhabi's Center for Global Sea Level Change, said in a news release. This can give researchers a sense of how the overall global climate is changing. The calving event, captured in stunning footage by a team of researchers on site, spurred several other tall icebergs to separate as well, with some even flipping over entirely.
