Okay. How did they get this video?
Penguin with a camera, of course
Hopefully not lost in Canadian waters.
This is especially cool since I started watching The Terror last night on AMC
This submarineoperation is so, so beautiful.
So, they break through the ice, let a photographer off, then submerge again so they can be photographed surfacing?
