Arctic sea ice / Re: The 2017 melting season

I'm not very familiar with how NSIDC calculates sea ice extent, if it's based upon the pixel-map provided here or not.

But from what I can see of satellite imagery, and compare that to the sea ice extent graphics, it's clearly very wrong.

Probably reporting a lot more than actual extent?

Perfect weather conditions with little clouds on the imagery coming in for today, it is not complete yet, but what is available I have attached. Have to look at all the way forward to June 19th 2016, for a similar situation.

Is there any history of this area being open... ever(in the satellite era, anyway)? Along the Greenland North coast, I mean.

I'm not really sure what the implications of it is, so I'm curious if there's anything comparable that's happened.

Lincoln Sea May 23th 2016 vs 21/21/23 2017. I made a stitch of the 3 days, to make the image as clear as possible with least clouds.

As a follow-up to the post by jdallen, I made an animated gif of the same view (March 20-21, varied to get less clouds) for 2013-2017, 5 sec delay between images.
