And then you have what are called ‘tabular icebergs that are wide and flat, and long, like sheet cake.'” These are the long fingernails that grow and split off the ice shelves. Our unique rectangular iceberg is barely more than 1km long and won’t last anywhere near as long. “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 crazy subsurface. This can make the sheets of ice “rectangular and geometric.” 16, 2018, during a flight over the northern Antarctic Peninsula.
The iceberg was somewhere in the neighborhood of a trillion tons, by far the largest ever recorded.īut how does an iceberg break off perfectly angled, you’re still wondering? Kelly Brunt, an ice scientist with NASA and at the University of Maryland, spoke with Live Science and said it’s a fairly common phenomenon that’s not unlike a fingernail growing too long and cracking off at the end. A rectangular tabular iceberg was photographed by Operation IceBridge on Oct.
RECTANGULAR ICEBERG IMAGE FULL
NASA NASA released new photos of the unnatural looking rectangular iceberg showing the full extent of the sheet cake like iceberg. But new images from NASA reveal an Antarctic iceberg that is so exquisitely neat in its geometry. Rectangular shaped iceberg found by NASA in Antarctica.
RECTANGULAR ICEBERG IMAGE CRACK
Some two years after the crack was spotted, an iceberg of enormous proportions was created when Larsen C broke apart. The platonic ideal of an iceberg is a jagged hunk of ice that looks like a floating mountain crag. And now Larsen C is going the way of the dodo, as well. Shortly after, in 2002, Larsen B began to fall apart, and researchers began to panic a little. The Larsen Ice Shelf used to be comprised of three main shelves, Larsen A, Larsen B, and you guessed it, Larsen C. Larsen A, the smallest of the three, collapsed in 1995. The once-long rectangle berg did not make it through unscathed it broke into smaller bits. Measuring in at just over 70 miles long and 300 feet wide, the rift extended downwards about half a mile. An area of geometric ice rubble is visible in the Landsat 8 image (top and below) from October 14, 2018, two days before the IceBridge flight. The rectangular iceberg, photographed as part of a topographic mapping project tracking changes in polar ice shelves called Operation Ice Bridge, fractured in May after A-68 crashed. Larsen C gained some notoriety back in early 2016 when a giant crack appeared in it. The iceberg’s sharp angles and flat surface indicate that it probably recently calved from the ice shelf.” “A tabular iceberg can be seen on the right, floating among sea ice just off of the Larsen C ice shelf. “From yesterday’s # IceBridge flight,” NASA wrote. Tabular icebergs are one of them, and NASA’s Operation Icebridge program recently posted an image that proves it.
