I don't have any pictures, but I've seen the docks at Hall Beach, Churchill, Rankin Inlet, Nanisivik, and Cornwallis Island, all in the Canadian Arctic.
It turns out I'll be going to Rankin and Hall next week so I'll try and get a picture or two.
Most Arctic communities don't have docks; the ships anchor and supplies or passengers are lightered back and forth. Traditional docks would be destroyed each year by the sea ice.
The few permanent docks designed for tying up to are usually steel or concrete cribs filled with rocks and then levelled with gravel so vehicles can drive up. Churchill is an all concrete dock, but built the same way.
These docks all are constructed parallel with the shore, not sticking out into the bay, again so the ice doesn't rip them apart.
I'm curious, do you have a specific dock in mind?
Regards,
Bruce
