Clouds or melt ponds?
Looking at Worldview visible, North of Svalbard (details in image names) & the ice looks qualitatively different than it was previously.
It could just be cloud formations but, if so, these would have to be strange given what I would describe as a 'grooves & angles' appearance.
It was above freezing in the region displayed, around approximately 83.63N, 4.17E, on 2018-05-06 at 1200 UTC. (It's colder there now, ~-10 degrees C.)
So could the Worldview experts comment on whether large scale melt ponds could be an alternative possible explanation, even early in May?
