Well here’s something you don’t see everyday: an iceberg so incredibly geometric fit you ‘d think it was deliberately sculpted with a gigantic chainsaw. Researchers have documented this sort of thing in the past, but this latest ‘berg, which just recently split from Antarctica’s Larsen C ice shelf, occurs to be a rather extraordinary example.
What you’re taking a look at here is a tabular iceberg. Unlike the icebergs of non-tabular range, such as the irregularly shaped berg that sunk the Titanic, these pieces of ice are distinguished by their flat tops, high sides, and in some cases enormous sizes. At their biggest, tabular icebergs can extend for hundreds of miles in length, and reach hundreds of feet below the surface area.
NASA researchers found this iceberg in Antarctica on October 16 as part of the Operation IceBridge program– a continuous objective to keep track of polar regions and track the world’s worldwide environment system.
Tabular icebergs are the residues of calving events, where a large strip of ice breaks free from an ice shelf. In this case, an uncannily square-shaped iceberg broke away from Larsen C, the exact same ice rack that produced the enormous A-68 iceberg back in July 2017. Based on its fairly smooth edges and beautiful condition, this berg likely only calved really recently, according to NASA.
Talking to LiveScience, University of Maryland Earth researcher Kelly Force compared calving occasions to a long fingernail that eventually snaps off at the end; the procedure typically leads to relatively ideal geometric edges. This berg hasn’t been determined yet, but Impact says it has to do with one mile across (1.6 kilometers), which isn’t not particularly large. By contrast, iceberg A68’s surface area measured some 2,240 square miles (5,800 kilometers) at the time of calving. Force added that just about 10 percent of the iceberg’s mass shows up, the rest being underwater. So what you’re seeing here is just the idea of the … uh … you know what.
Needless to say, this photograph isn’t informing us the entire story. It’s uncertain the entire iceberg is perfectly geometric throughout. However who cares– this picture is an instantaneous classic.
