Again Lena Delta.

As surreal as beautiful.

On the other side of things, the Barents doesn't look a whole lot healthier. <sn>
Both ecmwf and gfs forecasting below 960hPa storms in the barentsz on saturday, though, in extent terms, it might just suck more older ice out of the CAB

edit: Mercator model indicating the underlying 34m current north and northwest of FJL hasn't quite cooled down over the freezing season. Jan1-mar25. Open water due west of FJL may be wind driven.

Shame, would have spurred some interesting reading had it happened.

Forgive my naivety.
thanks for the research  :)  It's unlikely that this year's mostly first year ice is up to the job. Waves are over 3m today, forecast for over 4m tomorrow.

AMSR2 regional data anomalies for today's date
(2018- 2012->2018 mean)

I couldn't figure out a good way to normalise this to area-of-the-sea-of-interest so there is a bias in the size of the bars to some extent.
Nice graph. I think the absolute anomaly in km2 is okay, I don't see it as biased.

Definitely Simon. In both cases the "spine" seems to be caused by MYI drift pattern.

Interesting kink in the DMI temps recently, probably being facilitated by the high latent heat of peripheral seas.

Wonder how this will affect refreeze, particularly in the ESS.

Latent Heat of fusion will normally peg temps around freezing over melt season. Only when there is so little ice will the temp rise to reflect the waters temp instead.

This year DMI80N temps were a shade below other years.

Was this a sign that more aggressive melt was occurring and lowering the temp closer to the actual melting point of sea water?

If the ice covering this region was fragmented then melt would be occurring at a faster rate than if the area was cover by a few large sheets of ice?

If the temp continues to rise then we will know that a portion of the ice has now gone ( no more Latent Heat of Fusion) and we are, in fact, measuring more open water than past years? Enough to impact the DMI80N temps?
