NASA's sea ice survey captures bizarre, perfectly rectangular iceberg (PHOTO) – RT World News

October 22, 2018 Science 2 Views NASA's ongoing decades-long survey of polar ice has yielded some truly incredible photographs over the years, but one recently still captured what appears to be a perfectly, almost impossibly rectangular iceberg.      Snapped by NASA's ICE mission, as part of Operation IceBridge, the giant tabular iceberg borne of the Larsen C ice shelf looks as though it was neatly cut from the wider ice shelf using a giant band saw. From yesterday's #IceBridge flight: A table iceberg can be seen on the right, floating among sea ice just off the Larsen C ice shelf. The iceberg's sharp angles and flat surface indicate that it probably recently calved from the ice shelf. pic.twitter.com/XhgTrf642Z &#821 1; NASA ICE (@NASA_ICE) October 17, 2018 As with regular icebergs, just 10 percent of its mass is visible in the picture, though the subsurface mass is would look similar to what's visible above. However, we tend to think of icebergs as jagged and pointy, with the bulk beneath the surface, and with a penchant for ruining DiCaprio romances. Table icebergs are immense slabs of ice with a flat top and vertical sides that form by 'calving' or splintering off a much larger ice shelf. They can take more geometrically pleasing shapes than their more rugged, non-tabular counterparts. These particular icebergs can be truly immense, measuring hundreds and sometimes thousands of square kilometers across, such as the 11,000 square kilometers (4,200 square miles) B -15, the world's largest free-floating object ever…
