They have said that there are concerns about the "uncertain future" that the breakage would create for research opportunities there. Scientists have been observing the brunt ice shelf since 1915, but say this crack would be the largest since observations began in the decades ago. The scientists said: "It's not yet clear how the remaining ice shelf will respond after the break, posing an uncertain future for scientific infrastructure and human presence on the shelf, which was first established in 1955."
A notable crack occurred
NASA said the rift was "previously stable for about 35 years, this crack has recently started accelerating northward." As 1964, NASA's satellite imagery showed the rift, also known at the "Halloween crack" which first appeared in October 201
This crack was extending east from the area known as The McDonald ice rumples.
Glaciologist at NASA's Goddard Space Flight Center Joe MacGregor said: "The near-term future of the brunt ice shelf depends on where the existing rifts merge relative to t he McDonald's ice rumples
"If they merge upstream of the McDonald's ice rumples, then it's possible that the ice shelf will be destabilized."
NASA has said that the calving effect of the iceberg was part of the "life cycle
Through satellite imagery and NASA's research planes, they are able to discover and study icebergs.
In October, a NASA research plane discovered a mile wide straight-angled iceberg with perfect right angles in the Antarctica.
The iceberg was known as a "tabular iceberg", recognizable by its clean-cut edges.
This kind of iceberg forms when it breaks ice shelfs with precision, but is
Kelly Brunt, a Glaciologist at the University of Maryland, said in an interview to Live Science: "We get two types of icebergs."
"We get the type that everyone can imagine in their head that sank the titans c, and they look like prisms or triangles at the surface and you know they have a crazy suburface.
"And then you have what are called" table icebergs "
" What makes this one a bit unusual is that it It looks like a square. "
