Here's one for my readers in the Frozen North, otherwise known as the Great Lakes, where I understand icebreakers are still having to cut channels for shipping. Here's a video clip of an icebreaker carving through ocean ice, filmed by members of its crew who disembarked and went ahead of it in order to film it passing them. It's fascinating to hear the ice crunching beneath its bow as it passes.
Like the man said, "That's cool!" (Very!)
