What is the difference with 2012?
July 26 2012 same area had sea ice far less broken, which eventually melted/compacted at minima. Although the East Siberian sea of 2016 had similar open water to the Laptev sea of 2012.
We can conclude from AMSR2 data and the NASA overviews that this Cyclone had not quite the same effect as August 2012 Low, after all it was not as strong, but did indeed create a great deal more open water, highlighting the fragility of sea ice surely to vanish come mid September, especially if the ratio of open water to sea ice extent was increased.
