Antarctic weather can deteriorate rapidly.
Field parties carry radios, tents, sleeping bags, stoves, food, and other supplies when heading out to do their research, even if they are just planning a day trip. On the bright side, there is plenty of chocolate available for people going out into the field. Field parties are equipped with special clothing designed to withstand the rigors of Antarctica. This gear is issued to people on their way to the ice and given back when they leave. Even with the best of clothing, constant vigilance must be maintained against frostbite.
