North Ellesmere/Greenland biggest in memory open water/very thin sea ice at peak of cold season

~Stunning,  given a quite cold winter in this particular region

    NASA EOSDIS March 19 2019,  huge thin ice open water area usually circular because of full moon tidal current towards the South.  Note the band of ice NW breaking away towards Kennedy Channel :

  March 12 2019,  this area is long standing,  despite temperatures in the -40's C.......   The only possible explanation I can come up with,  is the ratio of thin and old multi-year sea ice is greater than can be surmised by remote sensing means.  This follows last summer 's discovery of vast areas of never seen before open water just to the North of this anomaly.  Sea ice current was predominant towards same area all winter pushing summer's ice towards the Canadian Arctic Archipelago coast,  by persistent presence of Anticyclones over the Arctic Ocean Gyre area.   WD March 20 ,  2019
