ljgeoffIt's the beginning of the freezing season. Here are three posters on Neven's Arctic Sea Ice blog forum:

I thought the one idea(above) about all the fresh water from prior melting and that puddled near the ice and then refreezing quickly, made some sense. That would explain a pause when the salt water was reached. But how much melt water would stay through storms and rough seas?
What about the slightly warmer peripheral waters and the less than ideal air temps?

water temps are not slightly warmer, they are a lot warmer and a lot above average in peripheral seas. further air temps are way warmer above 80N than any previous year, including 2012. the energy/heat that has been there now for quite some time finally start to show it's effect. if the stormy conditions continue it will be a very late "real" refreeze because current temps do not explain the fast refreeze, must be a lot of freshwater and smaller floes floating around that held freshwater temps close to freezing temps.

The further problem we now have is, all that moisture falling now as snow will be piling onto that new ice, and reducing heat flow *out* of the water, all the while replacing/displacing heat flow out of the ice through the top of the atmosphere. I'm pessimistic about the coming refreeze and the condition the ice will be in at max.
