The entire CAA appears to be melting?
that's from snow on top of the ice melting and the water being essentially lost last trapped in the top of the ice.
Eventually as the structural integrity of the ice fails.
Those lakes slash slawski pools of water on top of the ice cold rain and what will be will be more of a benign grayish color ice like the rest of the Arctic.
This happening now it's actually pretty late compared to other years that the CAA mostly melted out.
If I recall correctly and years like 2007 maybe 2008 2010-2011 and 2012 this process took place in late May or early June.
we saw some of this happened about a month ago but it appears that the process stopped or actually some of that snow repros or got a fresh layer.
Now that is not going to reverse until the fall.
The main reason it's so hard to melt out the CAA channels is because even though they're surrounded by land mass they are located between 72 and 80 North.
When you were or above 75 degrees north these solarmount season is really only from about June 1st until maybe August 15th but probably really a little bit earlier than that.
The ideal way to melt out the CAA.
Would be a strong blast near record or record warm over for northern Canada in the last 10 days of May that decimates the northern Canadian snow cover and can bring above freezing temperatures all the way into the north central CAA.
If this happens and can trigger the abrupt albedo drop at the surface what name the snowpack.
Say because of that the albedo drops from like . 85-.90 to .65-.70.
If you follow that with a large ridge of high pressure typically in the dipole pattern that combination can lead to early in that area abruptly happening bursted how long it would normally take for solar insolation alone that time of year to cause the albedo drop.
We have seen in early June over the Arctic basin it takes sometimes 5 to 7 days straight sunny skies to cause the satellite to pick up the wet surface versus the previous dry surface.
probably because when that pattern starts that he has to go into not only melting the surface but it also partially gets trapped in the heating the air around it.
This is why albedo is everything.
Anyways the CAA this summer most specifically the Northwest passage that goes to resolute Canada would need an historically warm July to have any chance of melting out.
It's very unlikely we see it melting out this summer.
