A few days ago NASA’s IceBridge project hit the news, but not for any of its impressive scientific observations. Instead, a casually tweeted photo of a strange rectangular iceberg captured people’s imagination. Now, NASA has offered up a few more shots, and video, of this unusual sight, helping explain this common yet rarely seen phenomenon.
Known as a tabular iceberg, this sharp-angled piece of floating sea ice was seen during an IceBridge flight on October 16th. The flight was specifically surveying changes in glaciers draining into the Larsen A, B and C embayments. This particular iceberg, seen near the Larsen C ice shelf was spotted by scientist Jeremy Harbeck during the flight.
“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,” explains Harbeck.
