And something we do not see every day: a square iceberg! And yet, there is NASA recorded it in Antarctica last week, as part of the IceBridge activity, photography quickly became viral on social media.
D & # 39; yesterday #IceBridge flight: an iceberg table sits on the right, floating between the sea ice just off the Larsen ice floe C. The acute angles and the flat surface of the iceberg indicate that he has probably recently calved from the pack ice. pic.twitter.com/XhgTrf642Z

And not unfairly, because the photo is impressive: it looks like a huge ice cube that someone gave it that shape, not something that has a natural shape. Theories of conspiracy involving extraterrestrials in ice skating began, or for mysterious people with huge saws who wanted to send us a message, while many saw a parallel with the monolith playing a key role in 2001, The Odyssey of Space .
If not, how can you explain this strange thing iceberg who does not look like clbadic icebergs like the one that sank the Titanic, with the sharp peak? Yet there is an explanation, and it is not at all conspiratorial.
Pointed icebergs are one of two types of icebergs that exist. Why there are "tabular" icebergs, which are parallel to the shape and smooth on their visible side. Indeed, the largest iceberg ever recorded was taboo: the B-15, with an area of 11,000 square kilometers.
Glaciers often take these icebergs. The explanation of their form is given by the University of Maryland scientist Kelly Brad, who speaks to LiveScience: Think of him as an excessive winegrower who has sometimes broken. The piece that breaks up often has a perfect geometric shape, as in this case, although in this case, what gives it the impression is that it looks like a perfect square rather than a simple parallelogram.
She believes that this iceberg looks "cool" because its well-formed corners indicate that it has not been able to "devour" the winds and waves.
As for his size, he estimates that his diagonal should be close to 1.6 km and, as for all icebergs, we must estimate that only 10% of its surface is visible and the rest remains hidden. of water.
