I'm sure there will be other large floes approaching Nares Strait this year, lots of them, in fact. I do not expect any of them to block the Strait, however. "First" and "Second" came remarkably close, though - I'm rather proud of them! Back in the day (2012) we thought an honest-to-god iceberg that broke off of the Petermann Glacier would block the Strait, maybe for even a year, but it slipped by the islands.
