Differing resolutions confusions

~There is a whole lot less ice than 15% extent rule 16 KM grid suggests
~We explore differing resolutions

   Despite latest reports suggesting we are at minima,  not so, at minima again,  nope,  largely because of wind system changes, despite there is still a great deal of melting going on in the Pacific side of the Pole.  However a significant Arctic Ocean air temperature dipole exists, on the other side of North Pole temperatures are colder,  the ice on Atlantic side is largely more densely compacted than the Pacific quadrant,  not so much compared to previous Septembers.

NASA EOSDIS below transect looks at the visually cloud free area within the pink area on September 10 JAXA above.  

   NASA EOSDIS September 11.   Observe significantly huge  "Goodbye Waves"  sea ice in final melting stages, we can confirm without much of a doubt that16 km grid 15% extent rule  calls all of the areas seen here covered with 100% sea ice.  However the JAXA colored map above gives a better representation at 6.25 km per grid and describes reality better than 10 km resolution  which is likely the daily JAXA numerical value:

       The 10 km grid random scan same area reveals no 14% sea ice coverage,  so it is all read as 100%. Even if water covers a grid area by 80%......  WD September 11, 2018
