IJIS: 13,705,959 km2（March 16, 2017) down 112,108 km2 and lowest measured for the date.
Since IJIS/JAXA/ADS publishes a two-day averaged figure, that equates to a 224,216 sq km reduction between the unpublished single-day values for the 14th and 16th of March.
The published number given by Espen is the lowest in the .csv since the 16th Feb.
The NSIDC has just given their one-day figure for the 16th as showing a 134k sq km drop since yesterday, and is the lowest in that .csv since the 15th February.
Each of the above lends further weight to the suggestion (proposal? fact?) that the annual retreat is once more upon us.
But just to be different, the DMI chart went upwards.
