In summer of the South Pole, there are only bright days but no dark night. Amid such 'White Night', our icebreaker cruised through floating ice-filled sea, and there I met a countless number of penguins, seals, and whales.
In winter of the Antarctica, the sea is entirely frozen so that even icebreaker cannot sail and there is no day but night only.In that period, Antarctic bases are isolated and surrounded by total darkness and coldness of -40 degrees Fahrenheit.Such isolation, darkness, and coldness sometimes drove some workers to lose mind and even life.The only solace is beautiful aurora in a jet-black sky.
