Antarctica Time lapse: A Year on Ice

clipped from www.youtube.com Time-lapse video filmed in Antarctica, in and around McMurdo Station and Scott Base. Each year the sun is below the horizon for 4 months in the middle of winter, and above the horizon for 4 months in summer. During the couple of months in between we have more-or-less normal days. Includes shots of auroras and the very rare polar stratospheric nacreous clouds, which form when ozone depleting gases crystallize in the upper atmosphere in the intense cold. Summer population is about 1200 people, winter about 200.
