Weird rectangular iceberg explained by scientists

The B-15 iceberg is the world's largest free-floating object ever recorded

Tabular icebergs are wide and flat and long - "like sheet cake" - Kelly Brunt, an ice scientist with NASA, told Live Science journal.

In an image posted to Twitter, the iceberg looks to be a near-perfect rectangle, which NASA says indicates it must have recently broke off from the ice shelf and hasn't yet been hit by wind and waves.

The expansive ice shelves that create the icebergs are hanging off of Antarctic land, somewhat similar to the flimsy tape extended out from a tape measure.

According to experts, this rectangular shaped iceberg is the result of a natural phenomenon.

Simply put, many ice shelves, particularly in West Antarctica, are losing ice faster than they can be replenished.

This iceberg captured by NASA - akin to the Wilkins icebergs - was also pretty new and fresh, which certainly helped its profoundly sharp, nearly unnatural appearance.

Operation Icebridge use a highly specialised fleet of research aircraft to capture the images.

NASA was conducting a long-term aerial survey of polar ice, named Operation IceBridge, when the iceberg was spotted as they flew over the northern Antarctic Peninsula. The aim of this mission is to allow NASA scientists understand the changes in ice (thickness, location, accumulation, etc.) in recent years in Earth's polar regions. But these are just one of two kinds of iceberg classified by shape, called non-tabular icebergs.

Take a look at photos of the sharp-angled iceberg below.

When we think of icebergs, we tend to think of huge chunks of ice with pointy spires and domes, with its bulk extending down below the surface of the water.

Brunt added that even the scientists thought the find was unusual as it's "almost like a square".

While it is hard to estimate the size of the iceberg from the photograph, experts said it was likely over a mile (1.6 kilometers) in length.

The visible part of the iceberg only represents 10 percent of the entire mass, Fox News reports.
