@crandles: I was wondering about the green water, too. Could it have something to do with the very low angle of incidence of the sun now? The clouds look weird, too. (Same effect shows up in previous years around this time of the year, too.)

The differences in the Canadian Archipelago are pretty stark. Wasn't everyone saying a few years ago that this would be the last toehold for ice? The little that's there seems to be floating bergs now. (Also: anyone else watching the breakup of the ice shelves along the northeast of Greenland? They seem to be in their dying days.)

P.S. I've seen articles addressing windblown dust from distant deserts and local effects from road dust, but I've seen nothing addressing increase in transport of dust originating in the Arctic.
Is anyone aware of any work on albedo effects of Arctic dust? I mean dust from the Arctic that's been held in place for millennia by permafrost or soil moisture or trapped under snow or ice. The receding glaciers I've been to in the Andes have had lots of windblown sand (really uncomfortable for hiking). I've noticed some ice off of Greenland that seems to be covered with what appears to be windblown dust. Seems like this could be another feedback mechanism, especially around Greenland and the CA.
(IJIS AMSR-E data, btw)
Back-of-the-envelope math: If SIE decline for this year mirrors 2003 from the same date through September minimum, we wind up at 4.5mil, below 2008 but above 2007. If it mirrors 2007, we wind up just barely breaking 4.0mil, recording a new low for the satellite record. It seems highly unlikely that 2011 will not be at least our second-lowest on record unless something odd happens.
Thanks to everyone for the good info on the Petermann. Just based on some very rough analysis, there's not much of a chance of 2011 not winding up very low for SIE. Assume ice loss for the rest of the year mirrors 2003, a fairly mild recent year: 2011 winds up around 2008 for September minimum. Given conditions, though, it doesn't look like 2011 will be that forgiving.
Petermann Glacier questions, for anyone who might know much about it: 1.) Is it just me, or does that look like a large crack that's been growing over the past several weeks? (Not as big as the chunk from last year, but still sizable, assuming that is a big fissure.) 2.) Does anyone know where the "grounding point" is on it? Not sure of the right term, but the point where the beach would be sans glacier? I can't find anything specific to the Petermann on the intertubes.
Good eye. Looks like there's a bit of meltwater forming right in front of the camera. (I'm going to have to check this every ten minutes now because I want to see whether or not we get underwater shots off this camera.)
