Antarctica’s Larsen C Ice Shelf Rift Growing Rapidly
The large rift in the Larsen C Ice Shelf that we reported on a few weeks ago has continued to grow at a rapid rate since then, with a further 10 kilometres of length added since January 1st according to the researchers at the MIDAS Project.
The rift continues to run parallel to the shelf edge, though, so the distance holding the iceberg to the shelf (20 kilometres) remains the same as the last time that we reported on it. Obviously, though, as the images below show, even if the rift continues to run parallel, it will inevitability lead to an iceberg calving event.
This matters because, according to the researchers at the MIDAS Project, once the 5,000 sq. km iceberg calves, it will destabilize the whole Larsen C Ice Shelf — possibly leading to the disintegration of the whole ice shelf. The Larsen B Ice Shelf disintegrated in 2002 following a similar event as the one occurring now.
