The annual supply ship the American Tern being unloaded at McMurdo Station, Antarctica.
Time-lapse footage taken over 3 days of continuous sunlight towards the end of summer. This is the only time of year the ice is thin enough to get ships in.
In the background the Krasen, a Russian ice-breaker can be seen working a channel in the 2 meter thick ice to keep it from freezing up, so the Tern will be able to leave again.
Every 2.5 seconds of film equals 1 hour in real time.
