This year's trend line dipped below last year's only to go up again in the first two weeks of April, probably reflecting the late ice growth we saw here and there on the fringes of the ice pack, that also had trend lines on extent and area graphs flirting with the long-term average for a while. Very similar to 2010, but with thinner ice according to PIOMAS.
Here is Wipneus' graph for which he calculated the "expected" 2012 values, based on the same date values of 1979-2011 and an exponential trend. A caveat from Wipneus: "Note that the (not indicated) statistical error bars are quite large."Because there haven't been any updated CT SIA numbers I cannot update the average thickness map (PICT) I first posted last month. I'll update this post as soon as the sea ice area data comes online.
For the time being I'm posting the PIOMAS anomaly graph:
