Summer Sea Ice in the Laptev Sea

I've recently been looking at the PIOMAS Gice data, about which I will explain briefly here and in more depth later this month. Of the areas I have been looking at one that has struck me is the Laptev Sea, the other is Baffin Bay, on which I will blog in due course. But for now, Laptev:

March 2015 Status

Data is now in for March 2015, the early maximum is confirmed, temperatures over autumn/winter continue the pattern of recent years, and the volume increase in PIOMAS remains. This year takes volume back to 2010 levels, but the impact of 2007 remains clear. My entry for the 2015 Sea Ice Prediction Network (SIPN) is given at the end of this post.

Three Neat Videos.

I've just visited Cryosphere Today, and noticed a new heading 'Arctic Climate Feedbacks'. From the date of the video it references, it's not really new, the Youtube video is dated 22 January 2015. Anyway it led on to three short but impressive TED videos that neatly link together (well I think they do). Each video is only around 5 minutes long.

Large extent of older sea ice in the Beaufort Sea

I have processed images from the Drift Age Model of Fowler/Maslanik/Tschudi to draw attention to the extent of old ice in Beaufort. 2014, like 2013, enters the melt season looking more like a pre-2007 year in the highlighted region.

Rotten sea ice in the summer?

The 2015 melt season has begun, but as is the nature of a near sinusoid, the peak is rather boring with a small rate of change. So to alleviate the boredom, here's a post about compactness. ;)

Sea Ice Maximum 2015

Rather late, due to work commitments, here are my comments on the 2015 sea ice maximum. Three days ago NSIDC provisionally called the maximum at 14.54M km^2, on 25 February 2015. Does this mean anything for the coming season?

Mid March 2015 Status

So far the sea ice extent maximum was set on 22 February 2015, however as of 13 March extent is only 0.14M km^2 below, so it is too early to claim a maximum. That noted there are good grounds to suspect that the 22 February maximum may hold. PIOMAS data is covered at the end of the post.
