What's Going On With That Bizarre Rectangular Iceberg?

There has been suggestion that the iceberg could have broken away from the shelf as a result of global warming. He's a research scientist with NASA's Operation IceBridge, the group that took the stunning photo, and is based at the NASA Goddard Space Flight Center.

Nasa had found a piece of floating ice in Antarctica that is so flawless, it looks like it was deliberately cut.

NASA scientist Kelly Brunt compared tabular icebergs to "fingernails that crack off" in an interview with LiveScience.

Although it's often said that there are no straight lines or flawless 90-degree angles in nature, they do happen, albeit rarely.

Now, however, something weird has happened: NASA has taken a photo of what appears to be a perfectly flat, rectangular iceberg floating off the coast of the Antarctic.

An update should soon be rolling out to Samsung, LG, and Vizio TVs that introduces a more modern design and improved experience. Leading up to this announcement, 4K films had typically cost somewhere between $25 and $30 unless they were on sale.

But this is the first year that the scientists will also survey Antarctica using the new Ice, Cloud and land Elevation Satellite-2. This berg hasn't been measured yet, but Brunt says it's about one mile across, which isn't not particularly large. Brunt added that only about 10 percent of the iceberg's mass is visible, the rest being underwater.

"If you look at the recent icebergs that calved of iceberg A-68 (near Larsen C), you will see that many of them have pretty "rectangularish" shapes".

A NASA spokesman said: "It will yield an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice". Larsen A collapsed in 1995, and Larsen B collapsed in 2002.

The Larsen C ice shelf is being closely monitored by scientists after showing signs of breaking up.

"You can see at between 7-12 July 2018 the weather conditions and ocean currents conspire to swing the trillion tonnes of the giant iceberg A68 in an anticlockwise direction", he said. "I should think we will see some interesting collisions with the ice shelf in the next few months".
