Hi Espen, I've been following the picture
 http://www.ijis.iarc.uaf.edu/cgi-bin/seaice-monitor.cgi?lang=e
Since you seem to be THE expert on following IJIS, or at least the one following it the closest, I was wondering if you can help me.

Do you know to what ice concentration the different color shades, from white to light blue, to heavy blue, correspond to? There seem to be about 5, and I'm interested to know which ones are at or above the 15% ice-concentration threshold used for the ice extent calculation.

If this is a refreeze, it is the earliest I can recall?

Thanks Bruce,

Yes I got several liters of dried and frozen Porcini for the freezing season and a great stock of them for many evenings with 100% Porcini Soup, I really found a Goldmine for these mushrooms in the deep forests of Sweden some of them were up to 40 cm in diameter and 30 cm in height and in a perfect condition.

The drop seems CH4 related, like the huge drop last year from the 2600 ppb CH4 event.

I'd not be quite so quick to make that assumption.  Synchronous yes; a casual relationship is much less clear.

I think we can make a much better argument for the short term drop to be related to weather. There are major weather systems - the remains of Nuri in the Bering, an unnamed powerful low in the north Atlantic - that are in play currently.

We could easily be seeing either weather having artificially driven up the coverage area, or knocking it back down by way of direct effect on the pack in peripheral seas.

I'm combing January type errors out of my scripts and graphs myself, so no sweat!  ;D

The graph above, for instance, was so eager to conquer even more previous years that it said "next target" was 0 km², lol. Basically because "lowest ever" never happened before.

Sure did, but impossible to say if it will last, or how long, of course. Though there is a trend for slower January *and* February refreezes over the past 3–4 years. Quite logically, as the sea ice collapse spreads around the year, I guess?

The IJIS/Jaxa website seems to be dismantled.
Affected are the Sea Ice Monitor, the daily extent graphs and of course the data files.
Announcement on the old Sea Ice Monitor page:

NOTICE:

Thank you for visiting our website.

This site will be closed on February 22, and might be unstable from February 15, 2015.

New sea ice monitor website will be coming soon. Stay tuned.

Meanwhile, almost equivalent information can be available at

I haven't found the colorful version of the sea ice extent graph, perhaps somebody knows?
