14 hour loop of a channel in the CAA, I don't know its name so left the lat, lon in there. Rotated so that North is up.
Nansen Sound upper left, Greely Fjord to the center and right. Eureka is just to the left of the lower left '80'.
I didn't realize this stuff was moving around like that. It looks to me like melt runoff is driving it, but what do I know? :-)
I was also very surprised at the movement - I'd have thought ice in those narrow inlets and straits would mostly stay put. But I don't think melt runoff can be the culprit. To me it looks like a strong wind is pushing ice out towards the left in that long central east-west fjord, while currents are pulling ice generally southwards in the other fjords and straits.
If you look closely at the top fjord that stretches to the right, the ice is floating in along the southern side and ends in a turbulent swirl towards the bottom of the fjord. This is entirely in accordance with how fjord currents work in Iceland, flowing in along one side and out the other, with turbulence somewhere towards the end (where the fjords tend to be deepest).
The strong wind in that one fjord is also something we see in Iceland and other narrow fjord/narrow valley environments. If the alignment of the valley/fjord is just right, the wind starts to funnel along and can get increadibly strong, while another fjord a few kilometers away that is slighlty differently orientated could be experiencing a wind-free day.
