Earlier this month, NASA revealed a wierd and entrancing picture of a ridiculously sq. iceberg. And NASA scientist Kelly Brunt alleged to Dwell Science that the berg was possible fairly contemporary, its sharp corners the results of just lately snapping off of an ice shelf and never having but been battered a lot by the weather.
Since then, nevertheless, NASA went again and checked out some extra proof. And it seems that the squareberg had a rougher beginning than what was initially believed. Satellite tv for pc pictures confirmed that it cut up from Antarctica’s splintering Larsen C ice shelf behind a a lot bigger, curved iceberg referred to as A-68 and made its method north into clogged, icy water.
The squareberg is a tabular iceberg, basically a piece of flat ice that broke off the ice shelf, relatively than one of many extra strikingly geometric, smaller bergs that sunk the Titanic.
“The berg cruised all the way in which north and thru a slim passage between the A-68’s northern tip and a rocky outcrop close to the ice shelf often known as Bawden Ice Rise,” NASA mentioned in an announcement. “NASA/UMBC glaciologist Chris Shuman likens this zone to a nutcracker. A-68 has repeatedly smashed in opposition to the rise and precipitated items of ice to splinter into clean-cut geometric shapes,” NASA added referring to Shuman, who can also be on the College of Maryland Baltimore County.
You may see the berg making its method by means of harmful waters on this picture:
Over time, it did lose its good sq. form, taking over extra of a trapezoidal formation. NASA mentioned it’s going to possible proceed to make its method north, the place it’s going to soften.
