New photos of a decidedly ellipsoidal abstract are alms the abounding account of this now-famous Antarctic anatomy — and it charcoal awe-inspiring as hell.
Scientists with NASA’s Operation IceBridge appear the aboriginal photo aftermost week, but it alone showed a allocation of the odd iceberg.
With abundant of the ‘berg out of the frame, it wasn’t bright how geometric the absolute anatomy absolutely was. Now, new photos appear by IceBridge scientists acknowledge the iceberg’s accurate shape. It isn’t a absolute rectangle, but it’s still a awful angular quadrilateral.
These photos were captured by IceBridge chief abutment scientist Jeremy Harbeck, who spotted the collapsed abstract a the Larsen C ice shelf. Collapsed icebergs are the articles of calving ice shelves — back ample chunks of ice aback breach apart — and they’re accepted for their awful angular curve and bland tops.
“I anticipation it was appealing interesting,” said Harbeck in a NASA statement. “I generally see icebergs with almost beeline edges, but I’ve not absolutely apparent one afore with two corners at such appropriate angles like this one had.”
In July 2017, Antarctica’s Larsen C ice shelf appear the astronomic A68 iceberg, which weighs about 1000 billion tonnes and occupies an breadth almost the admeasurement of the accompaniment of Delaware. Harbeck and his colleagues were investigating this massive anatomy back the geometric appearance was spotted.
“I was absolutely added absorbed in capturing the A68 abstract that we were about to fly over, but I anticipation this ellipsoidal abstract was visually absorbing and adequately photogenic, so on a lark, I aloof took a brace photos,” Harbeck said.
Interestingly, Harbeck spotted a additional ellipsoidal abstract during the aforementioned 16 October 2018 flyby. In the photo above, you can absolutely see three icebergs of note: The now-famous freakishly geometric abstract at far larboard (slightly blocked by the plane’s engines); the new collapsed iceberg; and, off to the horizon, the A68 iceberg.
Yes, it’s that huge — the amplitude forth the border band is a free-floating abstract barometer about 100km in breadth and about 30km wide.
Here are some added photos of collapsed icebergs, abounding of which were produced by the Larsen C ice shelf during the A68 calving event.

NASA’s Operation IceBridge is an advancing mission to adviser arctic regions and clue the planet’s all-around altitude system. It’s currently in the bosom of a five-week activity to blueprint icebergs in the Northern Antarctic Peninsula, a mission that’s appointed to achieve on November 18. There’s still affluence of time larboard in the project, so hopefully the scientists will bare added Antarctic anomalies.
