It’s too early@in the season to have huge blocks of ice... we just saw some really thin sheets of ice floating by. The Polar Explorer has a hull in front which is spoon like and can cut through 2m of ice and scoop it aside for the ship to go through. Would have been an awesome sight. Next time we come in Jan ... #yuenfamilyvacay#adventureinthecold#articcircle#floatingice#balticsea
The bizarre block of floating ice has almost perfectly straight edge making the naturally formed iceberg look uncannily man-made.
Experts said the striking ice-formation is completely natural, created as ice breaks away from an ice shelf.
The odd iceberg was spotted by a NASA scientist, who posted a picture to social media site, Twitter.
NASA was conducting a long-term aerial survey of polar ice, named Operation IceBridge, when the iceberg was spotted as they flew over the northern Antarctic Peninsula.
Senior support scientist Jeremy Harbeck spotted a very sharp-angled iceberg floating among sea ice just off of the Larsen C ice shelf.
Mr Harbeck said that seeing icebergs with such straight edges was not unusual.
“I thought it was pretty interesting; 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.”
“I was actually more interested in capturing the A68 iceberg that we were about to fly over, but I thought this rectangular iceberg was visually interesting and fairly photogenic, so on a lark, I just took a couple photos.”
