Central Alaska was one of the very few areas of North America to have a colder than normal Dec to Feb winter
this year.

I see the ice on the Tanana River (where the Nenana Ice Classic takes place) is extra thick this year. Over 4 foot of ice there on March 3rd.

It's amazing how little movement there was in the Beaufort gyre this freezing season. There is absolutely no arm with MYI this year.
90% of the world is religious, but somehow "love thy neighbour" became "fuck thy neighbours", if they don't agree with your point of view.

WTF happened?

@ freegrass .....doesn't look like much ice over 1.5 metres

Yeah, i tried to find the thickness of the MacKenzie, as i heard the area up to Slave Lake was warm. Never did find anything but air temp. Usually a press release when it does break up.

that is for Nov 25th 2023 it is an animation if you watch it to the last it shows mostly 2 meters thickness

It's amazing how little movement there was in the Beaufort gyre this freezing season. There is absolutely no arm with MYI this year.

I guess it's a bit of a double edge sword because if there was  an arm of MYI there, it could be vulnerable to melt in anycase. I will say though for the first part of March, weather conditions have been more favourable for the Beaufort sea with below average temperatures, winds blowing offshore/against the Beaufort Gyre and that HYCOM model does seem to suggest improved thicknesses as a result.

Looks like winds are set to switch though in the coming days so I suspect the smooth looking ice we got at the moment will start develop cracks so how it looks from above may look different in around 5 days from now.

It does look too me that despite volume being quite low, negative anamolies are mainly in a zone where the ice never melts out which is the north of the CAA and so far the Beaufort sea. We could well see something interesting in terms of ice conditions in this area come September but that is of course a long way off.

The JAXA sea ice extent maximum for 2024 was on the 11th March at 14,411,099 km2, 13th lowest in the 46 year satellite record, 0.41 million km2 above the longterm linear trend, and 0.29 million km2 above the 2023 maximum.

14th place! Not too bad for being in the midst of an absolute climate crisis situation. How is volume holding up in PIOMAS? Last time I looked at the graph it was basically up since 2012. I hope that continues.

Piomas volume was 4th a couple of weeks ago.

Piomas volume was 3rd as of March 1st, with thickness in 4th place as per Gero's posts:

If that is correct, does that mean the ice is thinner and spread out further.... in my head, that means the area can disappear faster than ever before.

Yes, for sure. That's why we see lower minimums in Sept.
