Cloud Vortex North of Baffin Island, Canada73.3N 87.8W
The light tan peninsula near the center of this image is part of Baffin Island, part of the Canadian Arctic Archipelago, in the territory of Nunavut. Above Baffin Island is Devon Island, whose notable feature is the bright white Devon Ice Cap.
Moving east, Baffin Bay is mostly covered by clouds. Some of these have taken on the swirled form of a vortex, as can be observed in the close-up.
Below Baffin Island, part of mainland Nunavut can be seen. The large, sediment-laden, greenish body of water in the lower left quadrant is Rasmussen Basin, a natural waterway through the Canadian Arctic Archipelago. It separates King William Island (to the north-west) from the mainland.
To the east of this basin is Pelly Bay, a natural inlet and an arm of the Gulf of Boothia. Like Rasmussen Basin, it also appears greenish, although this coloration is limited to its southern reaches.
