Earlier this month, NASA printed a wierd and entrancing photograph of a ridiculously sq. iceberg. And NASA scientist Kelly Brunt alleged to Dwell Science that the berg was probably fairly contemporary, its sharp corners the results of lately snapping off of an ice shelf and never having but been battered a lot by the weather.
Since then, nonetheless, NASA went again and checked out some extra proof. And it seems that the squareberg had a rougher delivery than what was initially believed. Satellite tv for pc photographs confirmed that it break up from Antarctica’s splintering Larsen C ice shelf behind a a lot bigger, curved iceberg known 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, somewhat than one of many extra strikingly geometric, smaller bergs that sunk the Titanic.
“The berg cruised all the best way 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 stated 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 be on the College of Maryland Baltimore County.
You’ll be able to see the berg making its method by way of harmful waters on this photograph:
Over time, it did lose its good sq. form, taking over extra of a trapezoidal formation. NASA stated it would probably proceed to make its method north, the place it would soften.
