On the purpose of this manual: Today people go from the United States to Antarctica in hours. Warm buildings and home comforts shield them from months-long darkness, high winds, and temperatures sometimes below -75°C. (-100°F.). At stations like McMurdo, life seems so normal that it is easy to forget Antarctica's dangers. Tragedy and disaster can strike unexpectedly. It has happened, and it will happen again. This manual will help you prepare for the possibility, when all seems to be going well, of suddenly being in a survival situation.
