Once they split from an ice shelf, they are often geometric in shape.
That's consistent with an iceberg calved from floating ice in that region, she said. A very basic imagery that we all have of an iceberg is an angular one with a small tip at the top of the water. The berg appears toward the end of the clip on the left.
Brunt explained the rectangle was likely formed by a process that's fairly common along the edges of icebergs.
The IceBridge mission began back on October 10th but it's far from over.
A triangular iceberg was also seen nearby, surrounded by several different types of sea ice. Over time, the sea and wind will start to erode its smooth edges. It was a naturally occurring phenomenon called tabular ice which, unlike the iceberg that sank the Titanic in 1912, has flat tops and steep sides.

It has a standalone mode in which you can get a PC like experience even without a monitor or keyboard, according to the company. In addition, there is a 13MP autofocus rear camera and an 8MP front-facing camera for selfie shots and video calling.
Brunt added that even the scientists thought the find was unusual as it's "almost like a square".
NASA asserts that the iceberg's precise angles and extremely flat surface, "indicate that it probably recently calved from the ice shelf".
Larsen A, an ice shelf farther north on the peninsula, broke up in 1995.
From the photo alone, it is impossible to determine the size of the iceberg, but Brunt estimated that the tabular iceberg is about a mile across.
Just past the rectangular iceberg, which is visible from behind the outboard engine, IceBridge saw another relatively rectangular iceberg.
But this is the first year that the scientists will also survey Antarctica using the new Ice, Cloud and land Elevation Satellite-2.
