Ice under cloud

Yesterday's flight took me north from Toronto, over Hudson Bay and into the western part of the Northwest passage, then over Melville Island and on into the Arctic Ocean.

These are digital photos from a commercial flight, with some post processing to balance colours.

Looking down through clouds at ice floes in the western part of the NW Passage.

I'm not sure whether the larger agglomerations of ice are parts of the ice pack that haven't broken up entirely, or are part of the multi-year ice that has broken free from islands or ice shelves..

Sea ice seen through a couple of holes in the clouds.

In the Arctic Ocean, we seem to have flown over an area where the ice hasn't broken up at all. We can clearly see frozen leads in the ice.
