Scientists in Red
The US National Science Foundation provides almost all the clothing, food, and camping gear you will need in Antarctica. There is a clothing warehouse in Christchurch, New Zealand (the place we fly from to reach continental Antarctica), where each field party member tries on the cold weather gear before they go to the field.
In McMurdo, your gear is waiting for you (put together by workers that are there during the winter) to check out and make sure it is what you need, e.g., you check your tents to make sure there are no holes (see below).
Why red coats? Maybe they chose red because it is easy to see whether you're on rocks or ice and snow. There is probably a safety factor of the "dumb beakers" (what the support people, especially the military folks, used to call us scientists!) getting lost somewhere! - Co-PI and Curator, Edith Taylor
