The process by which ice detaches from the glacier, known as the breakaway of the ice. "By capturing how it unfolds, we can see, first-hand, its breath-taking significance".
The 90-second video has captured the attention and concerns of several experts on the climate change matter, especially because the Helheim glacier dips into the ocean on eastern Greenland and it lost a very large chunk of ice that will be responsible for some eventual changes on sea level rise. Scientists have been keeping a close eye on the frozen river as a key indicator of global warming and sea-level rise, with its front retreating around 2.5 miles (4 km) between 1998 and 2013.
These fractures caused by sea level rising also indicate another strong repercussion for the upcoming years is that as these breaks continue to happen it will also be harder to control and predict how much and how often this will occur in the future.
The video shows a tabular (wide and flat) iceberg separate, then travel down the fjord where it smashes into another iceberg.
A 2017 estimate suggested that a collapse of the entire the Western Antarctic Ice Sheet would result in a 10-foot-rise in sea level - enough to overwhelm coastal areas around the globe, including New York City. "The better we understand what is happening, the more precisely we can predict and plan for climate change", explains an employee at NY University, Denise Holland. Such events could help researchers understand how glaciers will respond to natural variability and human-induced changes.
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.
