The environment in Antarctica is extremely dry. It is an average of 18% Relative Humidity in the lab at Scott Base and while the development of corrosion on metal artefacts is inhibited, the dry humidity is not so kind to organic materials. Great effort is made to prevent paper artefacts from curling during their treatments and to introduce a degree of humidity to aid the treatment of organic objects. A humidity chamber is normally constructed for this purpose:

We also suffer the consequences of the dry environment and continuously strive to remain hydrated by drinking copious amounts of water. Our water bottles have become permanent accessories. Moisturisers and silicon barrier creams are found distributed throughout Scott Base to help combat flaking skin and cracking fingers. Some people apply sticky tape around their fingers to prevent their skin from completely splitting, some apply eye-drops daily and everyone is seen applying lip balm regularly. And so, one very memorable Sunday, we constructed our own humidity chamber. Rain was made by spraying a room down with pressure water and for a few glorious hours we basked in rain, puddles and high humidity…
