The August Extent Loss Oscillation

In my July Status blog post I rounded up by mentioning a possible oscillation in August NSIDC Extent losses. Using the Wipneus extent calculation based on NSIDC concentration, and with the benefit of 2014's August figures, I think it is worth looking at the again.

However I don't have a convincing explanation, and at this stage I am not convinced it needs one.

PIOMAS August 2014

 PIOMAS August data is now out, this is the last monthly status post for 2014. More analysis of this highly unusual year will follow, and occasional commentary on the coming freeze season will follow. But now that the melt season is essentially over there are other sea ice related matter I want to get onto.

PIOMAS? Too busy...

I'm too busy to do a proper write up on the August PIOMAS data, that will remain the case until Sunday. So until then here's one graphic from the August PIOMAS gridded data, I think it puts the significance of 2014 into its proper perspective.

That is a massive slug of thicker ice going into the 2014/15 winter. The derived data has been updated, link, but the daily data has not been updated as gridded hasn't, that doesn't come each month.

2014 Melt Season Review

I've decided not to await the actual minimum for 2014 to do a post on the season. Now that virtually all the data is in and I've had an afternoon off to do the bulk of the work, here is my 2014 season summary.

June Sea Ice Area and Melt Ponding

I've previously blogged about the anomaly cliff in CT Area during June and its relationship with melt ponding. This anomaly drop is also seen in Wipneus's area and extent calculations based on gridded NSIDC data, it is not peculiar to Cryosphere Today Area.

However are the recent June anomaly cliffs simply due to spread of melt ponding, or is there something else going on?

PIOMAS July 2014

PIOMAS data is now out and the picture of another year of muted melt is confirmed. As of this June the net volume impact of the 2010 volume loss event has been wiped out. However this does not equate to a recovery of thickness or volume across the Arctic. Those still holding out for a crash this year are flogging a dead horse, those expecting a crash by around 2016 are walking towards the same horse, whip in hand.

The regional PIOMAS Data and Thickness Plots that I produce are now updated. See the top right panel on the blog for links.

July 2014 Status

July continues a year of moderate loss compared to the long term average. 2014 is very likely to repeat the high extent in 2013.
