As per the scientists, this tabular iceberg is said to be the products of the calving ice shelves.
The world recently got a look at a gloriously sharp-cornered "tabular iceberg" in a photo snapped by NASA scientist Jeremy Harbeck.
A68, which is about the size of the state of DE, calved off the Larsen C ice shelf in July of 2017.
"We get two types of icebergs: We get the type that everyone can envision in their head that sank the Titanic, and they look like prisms or triangles at the surface and you know they have a insane subsurface", Brunt told Live Science.
Obsolescence programmée: Apple et Samsung condamnés par l’Italie
L'Autorité de la concurrence italienne a sanctionné Apple et Samsung pour des pratiques commerciales qu'elle juge malhonnêtes. L'aveu d'Apple n'est intervenu que ultérieurement ( un bridage pour au contraire prolonger la durée de vie selon Apple ).
The images of the unusually shaped iceberg were captured by Jeremy Harbeck on NASA's Operation IceBridge, an aerial survey of polar ice, when it flew over the northern Antarctic Peninsula on October 16, 2018.
Taken during an October 16 research flight over the northern Antarctica Peninsula, the picture recently went viral. "I often see icebergs with relatively straight edges, but I've not really seen one before with two corners at such right angles like this one had."In July 2017, Antarctica's Larsen C ice shelf released the enormous A68 iceberg, which weighs about 1,000 billion tons and occupies an area roughly the size of the state of Delaware".
The us space Agency NASA showed a picture of an iceberg a flawless rectangular shape, with smooth surface and sharp angles. Harbeck and his colleagues were investigating this massive structure when the geometric shape was spotted. "Indeed, the iceberg definitely captured the interest of the public, and the original photo of the object was shot at an angle that made the iceberg appear nearly perfectly square".
On Tuesday, it emerged that Mr Harbeck had spotted two rectangular icebergs on the same flyover. That image also captures A68 in the distance. In fact, one other rectangular iceberg - let's call it Tabular B, and the first-seen one Tabular A for simplicity's sake - takes center stage in a newly released photo.
Ce sera bien Federer-Simon — Bâle
Le Suisse Roger Federer lors de son quart de finale du tournoi de Shanghai contre le Japonais Kei Nishikori, le 12 octobre. Un succès vendredi face à Roger Federer amènera très certainement son capitaine Yannick Noah à réfléchir à la question.

Operation IceBridge is an ongoing NASA mission to monitor changes in polar ice.
