NASA finds rectangular ice-berg in Antarctica - Yazata - Oct 25, 2018 There were two of these rectangular icebergs, one very rectangular, the other not quite perfect. https://www.nasa.gov/image-feature/goddard/2018/2-rectangular-icebergs-spotted-on-nasa-icebridge-flight The right angle corners and straight edges are extraordinary. This is the better one. This is the not-so-good one. (The better one is behind the outboard aircraft engine in the picture.) NASA photos. RE: NASA finds rectangular ice-berg in Antarctica - C C - Oct 25, 2018 Well, at least the imperfections in the 'berg of the second image made me feel a little less threatened by the prospect of having entered the Twilight Zone. ~ RE: NASA finds rectangular ice-berg in Antarctica - Yazata - Oct 25, 2018 I wonder if they might be man-made. Perhaps somebody placed explosive charges to crack them off an ice-sheet, perhaps with a plan to tow them up to the Persian Gulf or someplace as a supply of fresh water. (They might serve as aircraft carriers too.) RE: NASA finds rectangular ice-berg in Antarctica - Syne - Oct 26, 2018 If the good one were an actual rectangle, I'd be apt to claim in was the monolith, ala 2001.

Your photo makes that one look like a trapezoid. All of the edges look pretty straight. There's some kind of physical process doing this. Do natural cracks in ice propagate through the ice in straight lines to produce fractures like this? If that were the case, why don't more icebergs have straight edges?

RE: NASA finds rectangular ice-berg in Antarctica - Syne - Oct 26, 2018 They're call tabular icebergs, and they seem to be fairly common. But in fact, there is little that is particularly unusual about the iceberg photographed floating near the Larsen C ice shelf in Antarctica, as sea ice specialist Alek Petty explains. He is a research scientist with NASA's Operation IceBridge, the group that took the stunning photo, and is based at the NASA Goddard Space Flight Center.
