‘ we get two types of icebergs’, kelly brunt, a glaciologist with NASA and the university of maryland told live science. ‘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. The iceberg’s sharp angles and flat surface indicate that it probably recently calved from the ice shelf. The photos were taken as part of Operation IceBridge, an ongoing NASA mission to document. 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. A NASA project studying climate conditions in Antarctica recently snapped a stunning image of a rectangular iceberg that has left many observers online scratching their heads. the part visible on the surface comprises just the top 10 percent of its mass - the rest is hidden beneath.įrom yesterday’s #IceBridge flight: A tabular iceberg can be seen on the right, floating among sea ice just off of the Larsen C ice shelf. NASA scientists have captured images of an iceberg in Antarctica that looks perfectly rectangular.
Harbeck captured both the edge of the rectangular iceberg, and a slightly less rectangular iceberg. it’s difficult to tell exactly how big the iceberg is from the photo, but experts said it was probably more than 1.6km (1 mile) across. The rectangular iceberg appeared to be freshly calved from Larsen C, which in July 2017 released the mammoth A-68 ‘ice island,’ a chunk of ice about the size of the state of Delaware. the image was taken during an icebridge flight-an airborne survey of the planet’s polar ice that gives a 3D view of the ice that makes up the arctic and antarctic, providing vital information on how it changes over time. Icebergs such as this are known as tabular icebergs, characterized by their long form, sharp angles and flat surfaces. this particular ‘berg came from the crumbling larsen C ice shelf on the antarctic peninsula. the picture was taken last week by scientists on a NASA research plane, who suggest the it had recently broken away from an ice shelf. It is likely to move further around the coast, and slowly disintegrate and melt before it. The Washington Post (2018, October 23) There’s a perfectly rectangular iceberg floating in Antarctica. Capturing a remarkable moment of nature, NASA has revealed an impressively rectangular iceberg floating in the weddell sea off antarctica. Our unique rectangular iceberg is barely more than 1km long and won’t last anywhere near as long.
