JAXA is an index of Sea Ice extent which is preferred by many, because the observing platform has good resolution and has recently been mostly more reliable than, say, NSIDC. It's the one I present first here. But for about a week it was not reporting, and this was at a late stage of melt and during an Artic cyclone.
When it suspended, melting had been sluggish, and 2016 was falling behind 2012, 2007 and 2015. However, during the break melting was higher, and 2016 is now in clear second place, behind 2012. It won't catch 2012, and will struggle to stay with 2007, where melting lasted well into September. However, it is ahead, and is quite likely to stay ahead of 2015, finishing at least third in recent years. Neven's (and forum) is the place to stay in touch.
