NASA discovers a strange geometric iceberg in Antarctica

An iceberg in Antarctica is so astonishingly rectangular that you would think it was carved out using a big chainsaw deliberately. The researchers have reported of such happenings earlier but this slab of the iceberg, which happens to spit from the Larsen C ice shelf recently, is an unbelievable and pretty unnatural example given the fact that it has perfect 90-degree angles on all sides.

NASA captured the remarkable image of the iceberg on October 16 as a part of its Operation IceBridge mission, a project which aims to picture the polar areas of Earth to understand better what changes have taken place in the climate in the recent years.

Many of us are quite used to looking at angular icebergs in images, which have just a tiny tip pointing out of the water. However, there also exist completely distinct kinds of the iceberg which are known as a tabular iceberg. Unlike the non-tabular kind of icebergs like the weird shaped ‘berg which sunk the cruise Titanic, such ice chunks are differentiated regarding their steeper sides, flat topside and at times huge sizes.

The tabular icebergs generally split from the ice shelves, which are the large tabular shaped thick ice bodies. Whenever there is a cleanly calved iceberg, its angles are most likely close to 90-degrees. This iceberg is most likely not that old as otherwise the sea spray, waves and even the wind would have winnowed away its perfectly carved sharp edges and made them round, said NASA researcher Kelly Brunt to Live Science.

Although this ‘berg is pretty strange due to its perfect geometric shape, the image of the iceberg is not telling the entire story, and it is still doubtful whether the iceberg is entirely tabular shaped entirely or not. The iceberg has not been measured yet, and the researchers at NASA now intend to study the phenomenon of how ice shelves calve out via the Operation IceBridge mission.
