Nature follows certain laws, but the results are most often fickle and asymmetrical, like clouds, coastlines, and ocean waves. But when NASA scientists flew a test flight over the northern Antarctic Peninsula a couple of weeks ago as part of Operation IceBridge, they noticed a neatly carved, rectangular iceberg drifting calmly in the middle of the chaotic ice. Everyone found this find quite interesting.
While icebergs with relatively straight edges are fairly common, this was the first time anyone had seen an iceberg with two right-angled corners, explained Jeremy Harbeck, senior scientist at the IceBridge program.
This type of rectangular formation is called a tabular iceberg. They are most often wide, flat, and long, like a sheet cake. Such icebergs chip off the edges of ice shelves like peeling nails if left untrimmed for too long. These fracture lines can form interesting geometric structures such as rectangles and triangles. This rectangular iceberg has a width of about one and a half kilometers. It just recently broke away from the Larsen Ice Shelf.
It is worth noting that the wonders of the ice world never cease to amaze us with their diversity. For example, icebergs can also often be striped, whereby the stripes are painted in different colors.
