Scientists keeping close watch on the Larsen C Ice Shelf in Antarctica have **ticed something new: The rift, which has been opening across the shelf for some time, **w has a sibling.*

Using a highly-sensitive European Space Agency satellite k**wn as Sentinel-1, scientists have been tracking the progress of a lengthening and widening ***** across the floating Larsen C Ice Shelf. Once this ***** reaches a certain point — exactly when is unclear — it could break off one of the largest icebergs on record.*

Recently, though, the main fissure has **t progressed further across the ice shelf, since it's hung up in an area of softer ice k**wn as a "suture zone (https://www.google.com/amp/www.bbc.co.uk/news/amp/39779761)," slowing its forward speed.* Read more...
