Researchers from NYU Abu Dhabi have caught an iceberg calving from a glacier in eastern Greenland on camera.
Calving is when an iceberg breaks off from a glacier. The scientists were researching the effects of climate change at the Helheim Glacier.
The video shows a tabular (wide and flat) iceberg separate, then travel down the fjord where it smashes into another iceberg.
The impact causes the first to break up and flip over.
The event was filmed late on June 22 and lasted about 30 minutes. The video above has been sped up.

A team of scientists led by David Holland, a professor at NYU's Courant Institute of Mathematics and NYU Abu Dhabi, shot the video.
Understanding how calving events take place is, the researchers say, important for developing simulations for sea-level rise brought about by climate change.
A 2017 estimate indicated that if the entire Western Antarctic Ice Sheet collapsed, sea levels would rise about three metres.
